VRV IV total solutionsto maximise energy efficiencyEnergy in buildings

In many commercial buildings, there are energy balance requirements.

Energy is needed for both heating and cooling, for hot water and

refrigeration, as well as for ventilation. Typically, these functions are

powered and operated by separate systems and all of the energycollected by these systems is rejected into the outside air.

But with a VRV solution, many of these building HVAC services can be

operated by a single system, which can recover waste energy and reuse

it to provide heating or cooling capacity elsewhere within the building.

Understanding whole building needs

Heating, cooling, refrigeration and air conditioning account for around

40-50% of a typical building’s energy usage. Most buildings rely mainly on

primary energy from energy supplier.

However, by understanding the whole building’s heating and cooling

needs at the outset, an integrated climate control solution can be delivered

that offers much higher energy efficiency levels, thus reducing the energy

consumption and carbon impact of a building.

Daikin has the technology, and all the products, to deliver the definitive

answer: a total solution that redefines efficiency.




VRV Heat Recovery heating and cooling solutions

Air curtains

Biddle air curtains are the ideal solution for retailers

and consultants to combat the issue of climate

separation across their outlet or office doorway. Usinga combination of rectifier technology, air velocity and

temperature control, they deliver greater comfort to

staff and customers alike, all year round, in all weathers.

AHU and VAM connections

Air handling units provide bulk air movement around

a building, to provide ventilation and maintain indoor

air quality. By using a VRV system to connect directly

via a refrigerant circuit, the VRV IV systems are ableto provide heating and cooling to air handling units

to reduce or eliminate the increased loads on the air

conditioning system due to fresh air.

Hot water

The waste hea t from offices,

comms rooms, open reception

areas, or even industrial

applications can be re-used

to provide, not just sanitary

hot water, but also underfloor

heating or water for an Air

handling unit (AHU).



Redefining efficiencyof VRV technology

For climate control in all types of buildings, the mission to

achieve ever greater efficiency is relentless. Over time, progress

is typically made in marginal refinements of technological

design or operational control. Until now!

Variable Refrigerant Volume [VRV ] was first developed

by Daikin over 30 years ago.

This game-changing innovation revolutionised

heating and cooling, providing the ability to operate

different climate control settings simultaneously in

various areas of a building.

By circulating only the volume of refrigerant

required at any given time to meet the capacity

demand, VRV offered two key benefits: reduced

energy consumption and greater control for

building occupants.

Since its introduction, Daikin has led the way in

taking this technology to new levels of efficiency,

comfort and control.

Now Daikin has completely re-designed this

technology to create our market-leading climate

control solution: VRV IV Heat Recovery.

The result is over 30% more efficient than

previous systems.



Real efficiency of design takes into account the lifetime of a

system, not just today’s known requirements. A building’s tenants,

uses and internal layouts may change – so its HVACR system may

need to adapt.


in design

Build in future flexibility

with Multi-BS boxesA change of tenant or building

usage typically requires substantial

changes to branch selector (BS)

boxes and pipework. BS boxes

usually have a limited number

of unused fan coil connections.

But with Daikin’s new multi-branch

selector boxes, that restriction no

longer applies.

For example, a single fan coil could

be attached to a 10-way box,

leaving 9 ports unused for futureneeds. Each of those vacant ports

could later be used for 14kW fan

coils, or to serve the high demand

of a communications room.

There should be no need to fit

different or additional BS boxes.

Only the pipe work needs to be

changed in order to reposition fan

coils for the new configuration.

However, Daikin continues to offer

single BS boxes, so a dedicated boxcan easily be added to the main

pipework, if required.

functions in a new more user friendly way. Further

details will follow.



Advanced IESmodelling capabilities

To bring advanced VRV Heat Recovery modelling capabilities

to the market, Integrated Environmental Solutions (IES) has

partnered with Daikin UK to integrate the Daikin Dynamic VRV

Systems Sizing Tool within the IES Virtual Environment (IESVE).

This software tool enables architects and engineers to

accurately establish the performance of these state of

the art systems within their building project.

Users can automatically size the system and select

the correct VRV indoor and outdoor unit model-

number based on the buildings heating and cooling

loads. Full thermal simulations then reveal annualloads, power input and efficiencies.

The tool allows users to compare alternative

configurations so that they can easily evaluate the

best option to maximise energy efficiency and lower

building energy use.

The software can be used with version VE6.5 onwards

and covers the whole Daikin VRV range.




Sound levels in buildings are a major factor in occupant comfort.

We have made dramatic reductions in the sound levels of our

BS boxes with the introduction of new technology so you can

be confident in achieving your clients’ expectations.

These reductions have been made possible by completely

redesigning the expansion valves and carefully refining and testing

the control logic to deliver the lightest, smallest, most efficient and

quietest range of Branch Selector boxes available on the market today.

Branch Selector Boxes designed for low sound levels

The Daikin 4 way multi box offers a sound reduction of 6.5 dBA when compared against other manufacturers under normal operating

conditions. It also offers a sound reduction of 13.5 dBA (sound pressure when changing over from one mode to another) when compared

with previous models.

in installationFor installers, efficiency is all about time and profitability:

the time taken to fit and commission systems, meet project

deadlines and avoid delays due to unexpected complexity or

changing conditions.

Efficiency in installation is pivotal to competitiveness in project tenders. Ultimately, it can

also be the difference between profit and loss on the job.

The new Daikin three-pipe VRV IV Heat Recovery system takes no longer to install than

a two-pipe system. In fact, our latest technology is designed to make installation faster,

easier and more flexible than ever before.

Smaller Multi-Branch Selector Boxes [BS]

To make system fitting easier for installers, our range now includes

4, 6, 8, 10, 12 and 16-way BS boxes. Unlike other manufacturers’

multi-boxes, these do not require complex separators inside.

Accordingly, all Daikin multi-boxes are at least 30% smaller –

and our 4-way and 8-way boxes are actually half the size of other

manufacturers’ equivalents.

A single BS box is also available if required for a remote area

requiring independent control of heating and cooling

[EXAMPLES: comms room, or a newly-added enclosed office].

All Daikin multi-boxes will fit comfortably into a 300mm ceiling.

They are also quieter and up to 32% lighter than those of other

manufacturers. Unlike other manufacturers’ multi-boxes, each

port can be connected to a 14kW fan without any loss of cooling

capacity. Those other multi-boxes are also subject to a maximum

8kW fan coil on each port. So each Daikin BS multi-box can handle

75% extra capacity.

Easier commissioning and servicing

Daikin VRV IV technology includes advanced software to simplify

system commissioning and servicing as well as multi-site

commissioning and control of installed systems.

The VRV configurator incorporates a graphical interface so that

settings can be pre-prepared off-site for high-speed uploading on

site. Among other benefits, this reduces the time required on a roof

to configure outdoor units, as well as reducing set-up errors that

would otherwise require repeat visits to site.

In addition, the software allows engineers to check systems,

evaluate operational data and identify any errors.

At the core of this technological breakthrough is Variable

Refrigerant Temperature [VRT]. New generation VRV doesn’t just

control the amount of refrigerant in the system; it also controlsthe temperature of that refrigerant.

Totally redesigned withVariable Refrigerant Temperature [VRT]

This means the evaporating and condensing temperatures can be

tailored precisely within an HVAC system to achieve the optimum

balance between comfort and efficiency.

The system adjusts intelligently to weather variations and real-time

working situations, as the load requirement fluctuates during the day

and within individual zones of the building.

In effect, it delivers a perfectly controlled interior climate without

wasting energy.

Market leading

operational efficiency

VRV IV Efficiency VRF Efficiency

Operational efficiency is much more than a nominal measure of energy consumption.

It is now measured in the real-life application of technology throughout the changing

seasons and the varying demands of building usage across each year.

VRV IV HR compared with astandard VRF* system*Variable Refrigerant Flow

Building type: Multi-storey office block

Time: Summer

In this example, the differing energy consumptions

are show in a multi-storey office block with reception

area, cellular and open plan offices, meeting rooms,

washrooms and communications room.

The building is routinely occupied from 08.00-19.00,

Monday-Friday and generally unoccupied outside

these hours.

The enhanced capabilities of our new systems mean

that we are already well-placed for imminent changes

in how efficiency will be rated in future.

From 2016, VRV systems will no longer be rated

on the basis of a single measure, but on their

performance over a typical year.




Daikin’s new generation VRV IV heat

recovery extends and enhances the

capabilities of VRV technology – giving

greater scope for smarter use of energy

and a more intelligent response to eachindividual building’s HVAC needs.



In the current commercial environment, retailers are under pressure

to reduce both store development and running costs. Legislation

adds further financial pressure, with initiatives such as the Carbon

Reduction Commitment Energy Efficiency Scheme meaning that

larger retailers need to improve energy efficiency dramatically,

or face stringent penalties.

Reducing

retail costs

Affordable, energy efficient solutions are vital to minimise lifetime

costs, while ensuring compliance with the latest regulations.

According to the Carbon Trust, the retail sector is responsible for

around 21 million tonnes of CO2 emissions per year. The retail

sector could cut its total spend on heating and cooling by a

massive £560 million annually by making energy savings of 20%.

The Carbon Trust also estimates that heating and hot water

account for 60% of a retailer’s energy bills. Typically, retailers with

air conditioning systems have double the energy consumption and

association carbon emissions compared with those that don’t. This

need not be the case if an energy efficient solution is implemented.

VRV solutions offer:

> Energy saving inverter heat pump technology, delivering

COP’s of up to 8 in mixed mode operation

> Individual control of each indoor unit

> A customisable solution using ‘variable refrigerant temperature’

to achieve the highest seasonal efficiency

> The highest standards of heating comfort, thanks to continuous

heating during defrost

> Flexible installation: the heat pump can be installed outdoors to

maximise commercial space internally or can be installed indoors

so there is no visual impact and low noise.

Versatile climate control

Climate control is key to creating a comfortable

browsing environment in store. However a uniform

temperature across the store is often not the best

solution. Retailers need the flexibility to control

multiple indoor units individually, so that the differentareas of a shop – such as the shop floor, storage and

staff areas – can be set at different temperatures in

order to provide the highest levels of comfort for staff

and customers.

Energy efficient VRV systems help to improve

comfort levels, while allowing each area to maintain

its set temperature. Micro processors balance

the system’s performance with the building’s

requirements to enable its compressors to operate

down to power levels 40 to 45% lower than more

conventional systems, thus reducing running costs

and carbon emissions.




Case study

Porsche Centre, Colchester

Extending a car showroom ahead of the launch of the sporty

Macan Turbo SUV meant the Porsche Centre in Colchesterneeded an equally standard-setting heating and ventilation

system to provide a comfortable environment for customers

and staff.

Echoing the Macan’s principles of performance, efficiency

and comfort the heating and ventilation system now serving

the enlarged display area – created by converting the former

workshop – is Daikin’s range-topping VRV IV heat pump and

a VAM ventilation unit.

The new heat pump operates alongside an earlier VRV III heat

recovery system, which serves the existing offices.

The ceiling units installed at Colchester are ideal for use in shopsand medium sized offices, because they can be used with ducts

of varying lengths. They consume 20% less electricity than similar

earlier models, thanks to a new DC fan.

The Daikin VAM heat reclaim ventilat ion (HRV ) unit, also mounted

in the ceiling, modulates the temperature and humidity of

incoming fresh air to match the indoor conditions. This provides a

balance between indoor and outdoor temperatures, significantly

reducing the cooling or heating load on the air conditioning

system while ensuring frequent air-changes.

The Range, Warrington

The Range is a nationwide retail chain offering a variety of

mid-priced goods for the home – DIY, homewares, furniture,lighting, arts and crafts and garden products.

The Daikin systems ser ving The Range’s 7,800m2 store in

Warrington provide a complete solution for climate control

and hot water. Seven VRV IV heat pump condensing units and

71 self-cleaning Roundflow Cassettes heat or cool the shop floor

in response to commands from the Daikin RTD-20 retail control

system. A VRV III heat recovery system and standard fan coils

provide simultaneous heating and cooling in the offices and

other back-of-house facilities – as well as hot water.

The VRV IV heat pump is 28% more efficient than earlier models,

as its Variable Refrigerant Temperature technology adjusts to

provide optimal seasonal efficiency at all times. VRV IV alsoqualifies for ECA approval.

“ We were very happy to work with Daikin UK to incorporate

one of the latest fully integrated renewable systems, allowing

The Range at Warrington to have a fully controllable system

Efficient building and facilities management are key to minimising

operational costs within medium-sized offices and large

office complexes.

Efficiency in the

workplace

Heating, air conditioning, hot water and ventilation are all

significant areas of energy consumption. But neither the

commercial climate, nor the current legislative framework,

will tolerate wasted resources. Responsible businesses are

seeking new and innovative ways to rein in their running costs

and carbon emissions.

Daikin provides total climate management solutions that put

building managers in complete control of the indoor climate. VRV

solutions are ideal for medium to large buildings, helping installers,

specifiers and building managers to:

> Dramatically reduce the cost of hot water and heating byre-using heat recovered from areas requiring cooling

> Ensure controllable comfort, by simultaneously heating

spaces while cooling others

> Choose outdoor heat pump installation to maximise commercial

space internally or indoor installation to minimise the visual

impact and noise externally.

A healthier office atmosphereVRV’s integrated capabilities mean that ventilation and air

conditioning can be combined in one system, with air filtration

ensuring a steady supply of clean air. Energy waste is minimised

by recovering heat from the stale air expelled from buildings and

using it to heat incoming air virtually for free.

Cutting the cost of hot waterBy using VRV’s heat pump technology to recover

heat from areas requiring cooling, reclaimed heat can

be used to produce hot water for sinks, under floor

heating, showers and radiators. The entire system can

be connected to solar panels to provide additional

solar thermal energy for hot water production.

Centralised controls for officesManaging comfort settings and energy consumption

is easy with VRV systems, which offer user-friendly

controls that can be integrated with other buildingservices such as lighting and blinds.

> Easy to use touch screen

> Many energy saving functions available including

movement sensors, controllers with evening and

holiday schedules

> Energy consumption can be set per indoor unit

> Monitoring and control available for up to

128 indoor units

> Online monitoring and control available for

multiple buildings

> Controls can be integrated with other systems

e.g. blinds, lights etc.

> Energy costs can be managed and divided amongmultiple tenants.




Case study

Velocity, Brooklands

Energy efficient heat recovery air conditioning from

Daikin UK enhances the ‘green’ credentials of a stylish officedevelopment designed to attract ‘head office’ tenants at

Brooklands, in Surrey.

With their Breeam ‘excellent’ rating and low B ratings for

energy performance, the two buildings in the 9,885m2 Velocity

development sport a range of environment friendly systems to

create a top-class workplace that is economically attractive to

both landlord and tenants.

Named to evoke memories of Brooklands’ aviation and motor

racing past, the five-storey Velocity buildings symbolise

streamlined speed and their systems reflect the best in technology.

Solar shading on the south-facing aspects reduces solar gain,while rooftop photovoltaic and solar thermal arrays provide

renewable alternatives for some of the buildings’ energy needs.

Daikin UK’s VRV III heat recovery systems were specified for

Velocity’s office heating and cooling needs, giving the buildings a

total of 358hp of air conditioning power.

The entire air conditioning system is controlled automatically by

the Building Energy Management System, which is programmed

to keep indoor temperatures at 22-23°C all year.

“ Daikin is a personal preference of mine. They were first with

VRV and have led the field with improvements to the concept. Their systems are very reliable.”

Case study

Flow, Staines-upon-Thames

A structural extension to suit a major tenant moving into

a high efficiency new-build office development beside theRiver Thames provided an ideal opportunity to compare

the performance of two generations of Daikin VRV air

conditioning systems.

The original 6,709m2 development at Staines-upon-Thames

consisted of two buildings – Flow 1 and Flow 2. Respectively four

and three storeys, they were built speculatively and Category A

fitted for possible occupation by up to seven individual tenants

after completion in 2013. Both buildings have BREEAM ‘excellent’

ratings – exceeding the original aim of ‘very good’ through

increased on-site efficiency.

Complementing the buildings’ other efficiencies, seven separate,

independently controlled Daikin VRV III heat recovery systemswith outdoor units of 20hp to 38hp were installed.

However, the whole development has been let to an American

software company on a 10-year lease and contractors have

added walk-though access between the first and second floors

of the buildings.

The two-storey link adds another 173m2 of usable space,

requiring two additional fan coil units on each level, served by

the new 8hp VRV IV HR condenser.

A hotel’s reputation depends on how welcome and comfortable

guests feel during their stay – and Daikin UK has a complete solution

for hotels to help create the perfect ambience. Yet at the same time,

hotel operators must maintain complete control of their operating

costs and energy consumption.

Hospitalitywith economy

Daikin’s cost-effective solutions can offer total control of hotel air

conditioning, ventilation, heating and hot water, with stylish yet

silent, draft-free indoor units that promise a good night’s sleep.

And because VRV is a modular solution, upgrade and renovation

projects can be phased to minimise interruption.

Integrated heat recovery

Integrated solutions offer zone by zone control of hospitality areas

and guest bedrooms:

> Recovering heat from areas requiring cooling and re-using for

low cost heating and hot water

> Creating the perfect environment for guests by simultaneously

heating spaces while cooling others

> Maximising hospitality space with outdoor heat pump

installation, or opting for indoor installation in city centres,

to minimise external space and noise.

Heating water with renewable energy

Renewable energy can be used to produce low-cost hot water for

bathrooms, under floor heating and radiators, thanks to VRV heat

recovery solutions, which reclaim waste heat from areas requiringcooling to heat hot water up to 80°C.

Smart energy management

Daikin VRV systems can be controlled centrally,

in tandem with other building services such as

lighting and fire alarm systems, for optimum comfort,

efficiency and safety:

> Centralised management available for VRV systems

with up to 2,560 indoor units

> Controls offer intuitive navigation, graphicalinterface and extensive reporting

> Energy consumption can be set per indoor unit

> Controls can be integrated with other systems

e.g. lighting, fire alarms etc.

> Online monitoring and control is available for

multiple buildings.

Intelligent hotel room controller

Hotel owners need full control of energy use. A Daikin

intelligent controller can adjust the system setpoint

when bedrooms are vacant or windows are opened,

thus preventing unnecessary energy consumption

to maintain absolute control over the hotel’s runningcosts and environmental impact. Daikin’s intelligent

room controller:

> Connects to all types of controllers, including easy

to use touch screens

> Integrates easily with hotel management software.




Case study

Bloomsbury Hotel, London

In a nine-month phased project, the Grade II listed

Bloomsbury Hotel replaced an ageing air conditioningsystem to beat the ban on R22 refrigerant and achieve

significant energy savings.

As part of ongoing upgrade programme, the hotel’s owners,

The Doyle Collection, wanted to cut energy usage and CO2

emissions. They opted for a Daikin VRV-Q system, which is

40% more efficient in heating and 25% better in cooling than

R22 systems.

VRV-Q has the added benefit of allowing the re-use of existing

pipework and some indoor units – reducing replacement costs

and speeding up installation. At the Bloomsbury, the installation

cost savings were about 50%. The phased replacement also

minimised the impact on occupancy rates and therefore theeffect on revenue.

In its first year of operation, the VRV-Q system helped reduced the

Bloomsbury Hotel’s energy usage by 15,000kWh – independently

assessed as a 23.5% year-on-year saving.

“The Daikin system is more efficient and certainly quieter than

the old one. Our energy bills are between 23% and 26% lower

than before the system was changed.”

Case study

Chester Hotel, Aberdeen

A £5 million refurbishment programme, which saw the

Simpsons Hotel in Aberdeen transform into the five starChester Hotel, sparked some special creativity in air

conditioning design for public areas.

Chris Thoms, Mechanical Design Manager for Hutcheon Services,

Aberdeen, was tasked with providing a five star air conditioning

solution for the new-look hotel. The system chosen to air-

condition the public areas and the conference and wedding

facilities was Daikin VRV III Heat Recovery.

“ The client was keen on the Daikin system for its high energy

efficiency and the benefits of a VRV heating and cooling system,”

he says.

“ It was challenging getting the air conditioning for the mainconference room into the project because of the thickness of

acoustic insulation above the ceiling. There wasn’t really a ceiling

void to house the units.”

Various alternatives were considered, but the chosen solution

was to fabricate ‘domes’ matching the circular overhead light

fittings selected for the conference room. The domes provided

depth to accommodate Daikin slim ducted fan coil units, each

with a nominal 7kW of cooling and 8kW of heating.

Public buildings are under increasing pressure to lead the way in

sustainability, in order to reduce carbon emissions – and improve

energy efficiency as part of overall strategy to spend public money

more carefully.

The government estate makes up a significant part of the built

environment, providing working places for 5.4 million people –

about 18% of the workforce. According to the Office of NationalStatistics, ‘public’ buildings are responsible for about 10 million

tonnes of CO2 annually.

In seeking to meet energy efficiency targets across both public and

private sectors, government and its agencies have to demonstrate

a willingness to replace outdated and wasteful heating and cooling

systems with efficient modern technology.

VRV systems provide ideal solutions for most public buildings,

offering operating cost savings, a reduced carbon footprint,

high efficiency in all ambient conditions and a working

environment that is always comfortable for staff and visitors.

Public buildings lead the way




Case study

Portcullis House, Cardiff

Switching to Daikin VRV IV heat recovery air conditioning as

part of a major refurbishment project has given the ownersof a 3,600m2 Cardiff office building an additional benefit –

a healthy extra 350m2 of space to let to the new tenant,

the NHS.

Portcullis House, previously occupied by HMRC, has three storeys

of open plan offices and seven storeys of smaller offices and

meeting rooms in a taller wing behind.

An old four-pipe air conditioning system, with floor-mounted

fan coil units, piping and associated trunking on perimeter walls,

has been removed – yielding the 10% increase in lettable space.

Heating and cooling for the old system was provided by boilers

and chillers – all of which were in a poor state.

Daikin’s brand new VRV IV heat recovery air conditioning was

specified for its cutting edge technology and high efficiency.

As an added benefit, its refrigerant piping, branch selector boxes

and round flow cassettes could all be accommodated within the

existing ceiling voids.

Portcullis House has a fairly high degree of solar gain, which

means that it often requires simultaneous cooling and heating.

The VRV IV heat recovery facility means rejected thermal energy

from the ‘hot’ side can be used efficiently to warm the colder

parts of the building.

> 3 VRV IV heat recovery condensing units (22h and 26hp)> 38 Roundflow Cassettes (1.8kW to 7.2kW)

> 21 Wall-mounted fan coil units (1.2kW to 2.9kW)

Case study

Palace of Westminster, London

During a refurbishment project at the Houses of Parliament,

Daikin’s innovative VRV-Q plug-in system was selectedto replace outdated air conditioning systems using now

banned R22 refrigerant.

Like many other buildings with R22 systems, the iconic London

landmark had to make the change because of the phase-out of

the gas. New sources of R22 were banned in 2010 and recycled

gas was also banned from 31December 2014 under European

environmental legislation.

VRV-Q uses R410A refrigerant, which has zero ozone depletion

potential and reduces associated CO2 emissions. VRV-Q also

improves energy efficiency and is able to reduce energy

consumption by up to 40%.

VRV-Q offers a technically secure and cost-effective option to a

full system upgrade. It can reduce the cost of an R22 upgrade

by up to 50% because VRV-Q outdoor units are designed to

work with existing R22 piping – and potentially also controllers

and indoor units manufactured after 1996. This means only the

outdoor units and heat recovery branch selector boxes have to

be changed – saving time and reducing costs.

A fast and effective upgrade is possible because VRV-Q

operates at lower pressures to suit existing R22 piping, without

compromising efficiency levels. In fact, a VRV-Q 10hp system has

a COP of 3.98 and an EER of 4.00 – around 50% more efficient

than the equivalent R22 system it replaces.

The new standard in heating comfort

VRV IV Heat Pump for continuous comfort,even during defrost

Because the VRV IV Heat Pump continues to provide continuous

heating even when in defrost mode, it provides the answer to

any perceived disadvantages of specifying a heat pump for

monovalent heating.

Heat pumps are known for their high energy efficiency in heating,

but they accumulate ice during heating operation and this must

be melted periodically using a defrost function that reverses the

refrigeration cycle. This causes a temporary temperature drop,

which can reduce comfort levels inside the building.

Defrosting can take over 10 minutes (depending on the size of thesystem) and occurs most frequently between -7 and +7°C when

there is most humidity.

How does it work?VRV IV Heat Pump features a unique heat-accumulating element,

based on phase change materials, which provides energy to

defrost the outdoor unit while continuing to provide heating, thus

maintaining a comfortable indoor climate. The energy needed for

defrosting is stored in the element during normal heating operations.

How phase change material works

A phase change material (PCM) will store or release energy when

it changes phase from solid to liquid or liquid to solid.

The outdoor unit coil is defrosted …

… with the energy stored in the heat accumulating element …

… while indoors a comfortable temperature is maintained.

A field trial at a German fashion chain store

demonstrated how the innovative features of

VRV IV have improved energy efficiency

dramatically over previous models.

The results of the trial showed that the new VRV IV

system consumed much less energy, particularly

when cooling, compared with the VRV III system –in some cases up to 60% less. When heating, savings

were an average of 20%.

The Unterhaching trial demonstrates how VRV IV heat

pump technology uses a renewable energy source

– air – to provide a complete and environmentally

sustainable solution for heating, cooling, and

ventilation in commercial environments. The trial also

shows that businesses can only identify and control

energy wastage through careful and intelligent

monitoring of climate control systems, a servicewhich Daikin can offer.

The Daik in low-cost upgrade solution

4 Reuse drain pipes

Durable PVC pipes can be easily reused. Only flow tests are required.

4 Reuse refrigerant pipesPipes used for R- will also work with VRV-Q, thanks to lower

operating pressures of the system.

4 Reuse refrigerant branch pipes

There are no restri ctions when upgrading from a Daik in VRV system.

Other VRF systems require branch pipes to withstand pressure up

to . MPa.

! Replace indoor units and BS boxesContact your local dealer to check compatibility in case you need

to keep the indoor units.

4 Reuse remote control wiring

Reuse wiring when upgrading from a Daikin VRV system. In other cases,

this will depend on the cable type.

4 Reuse indoor-outdoor wiring

Restrictions: see remote control wiring.

! Replace outdoor units

Replacement VRV R22 is a hydrochlorofluorocarbon (HCFC) which was commonly used in air conditioning

systems. However, both new and recycled sources of R22 are now banned.

Many systems today are still running on R22. But as R22 is no longer available, now’s

the time to replace R22 systems. The good news is that Daikin’s VRV-Q solution delivers

significantly higher energy efficiencies, with the potential of saving up to 50%, compared

with installing a completely new system.

Always operational

Avoid loss of business

Replacing now prevents unplanned, lengthy

disruption of air conditioning systems. It also avoids

loss of business for shops, complaints from guests inhotels, lower working efficiency and loss of tenants

in offices.

Quick and easy installation

No interruption of daily business while replacing the

system thanks to phased-in, fast installation.

A future-proof,

high-quality solution

Customers can replace systems cost effectively from

other manufacturers with highly-efficient and flexible

Daikin VRV technology, featuring higher qualityindoor units that deliver enhanced comfort and

superior performance.

A cost saving decision

Reduce costs

System upgrades cost less, because only the

outdoor and indoor units need to be replaced.

This is also the easiest and fastest way to comply

with regulations for buildings.

Environment protection

Improved efficiency saves energy and lowers CO₂

emissions as well as reducing your energy costs.

Reduced energy consumption

These benefits will convince

your customer

Lower long-term costsEU Directives prohibit system repairs with R-22 after 31 December 2014. Delaying the

required R-22 replacement until an unplanned system breakdown is a losing game.

Replacement day will come. Installing a technically advanced system lowers energy

consumption and maintenance costs from day one.

Refrigerant branch pipes

Refrigerant branch pipes, including those from

other manufacturers, Y-refnets, T-refnets and headers,

can be reused under the following conditions:

✓ Pipes are corrosion-free✓ Pipes are insulated

✓ Pipes can withstand a pressure up to . MPa

✓ There are no special components that implement

decompression (e.g. oil trap)

✓ Installed copper pipework is in suitable condition

(piping thickness will generally meet specifications,

since the unique Daikin VRV solution operates at

lower pressure levels)

Refrigerant oil

Refrigerant piping can be reused if one of thefollowing oils was used: Barrel Freeze, Ethereal,

Ester, Ferreol, HAB, MS, Suniso.

Maximum piping lengths

and level distances

VRV-Q can be installed for piping systems with a total

length up to m. See the illustration below for
