Heat pump efficiency =

SCOP =

heating output / year

electricity input / year

The seasonal efficiency (also called SCOP) of a heat pump is the average efficiency over a whole year. The total heating output per year is defined by the climatic conditions and house specifications (heat load, required water temperatures, etc.), and is independent of the type of heating system.The total electricity input per year is the critical parameter, as this is what the customer pays for. This means the SCOP value can be seen as the real operating efficiency of a heat pump system.

Why choose

Daikin Altherma low temperature heat pump?

3 systems in 1: heating, cooling and hot waterDaikin Altherma is a total heating and domestic hot water system with an option for cooling. Based on heat pump technology, it represents a flexible and cost-effective alternative to a fossil fuel boiler. The inherent energy efficiency of Daikin Altherma makes it an ideal solution for your customers looking for reduced energy consumption and low CO

2 emissions.

Depending on the model and conditions, a Daikin Altherma heat pump delivers about 5kWh of usable heat for every kWh of electricity it consumes. This means approximately 80% of the heat is free! Talk about a good investment.

The high efficiency systemBy making use of the heat in the outside air, the system uses much less energy while occupants enjoy a stable and pleasant level of comfort. Also, maintenance requirements are minimal, keeping running costs low. Thanks to advanced compressor technology, the energy savings are even greater.

Why heat pump?The Daikin Altherma heat pump uses a sustainable energy source: extracting heat from the outside air. In a closed loop containing a liquid refrigerant, a thermodynamic cycle is created through evaporation, condensation, compression and expansion. This “pumps” heat from a lower to a higher temperature level. Via a heat exchanger the heat gained is transferred to the home’s warm water distribution system. This can be under-floor heating, low temperature radiators and/or fan coil units. For cooling, the system operates in reverse.

Best seasonal efficiencies

› Low-capacity 4-8kW range is equipped with swing compressor: integration of main moving parts in one component, assuring no abrasion and no refrigerant leakages, guaranteeing optimal reliability and efficiency.

› High-capacity 11-16kW range is equipped with scroll compressors: quiet, compact and robust, guaranteeing optimal operational reliability (no valves and built-in swing-link coupling) and efficiency (through a low initial flow and a constant compression ratio).

Swing Scroll

Daikin Altherma low temperature provides excellent ratings that comply with European legislation and certification schemes, and/or local incentive programs. Each capacity class has an individually sized compressor, dimensioned for optimal efficiencies per capacity range. This avoids having an over-dimensioned compressor with lower seasonal efficiencies. For example, the compressor of the 4kW class is designed to work at optimal frequencies, delivering the low capacities needed by houses with low heat loads. In addition, the Daikin Altherma optimises efficiency at all outside and water temperatures through:

› a pressure sensor for detailed measurement of condensing pressure level to evaluate the optimal amount of subcool

› an individual dimensioned plate heat exchanger per capacity class, to offer optimal efficiencies per capacity range

a. Low running costs: high heat pump efficiencies at all outdoor and water temperatures

Daikin Altherma low temperature maintains its high heating capacities even in the lowest outdoor temperatures. Electrical back-up heater assistance is required never or rarely. These high heating capacities, available across the whole Daikin Altherma low temperature 4kW-16kW range, are achieved thanks to the combination of technologies:

› Optimised controls to achieve higher frequency of use at low outdoor temperatures

› Liquid injection to avoid too-high discharge temperatures when high water temperatures are required at low outdoor temperatures

› Perfectly-dimensioned plate heat exchangers to maximise the heat exchange surface

When the heat load is lower than the maximum capacity of the heat pump system, the compressor can turn in partial load operation. This reduced compressor frequency results in:

› Higher compressor efficiency in partial load operation

› Delivered capacities exactly matching the actual heating demand of the building

› Obtaining the capacities needed with minimum energy consumption

› Less on/off operation, increasing the operation life cycle of the compressor

The partial load operation and optimal operation area can be illustrated by a typical application in Paris

Resulting in the best possible effficiencies

Efficient partial-load operation is especially important for the temperature range where the highest heat output is required. Typically, 80% of the total heat output is required in an outdoor temperature range of -2°C to 10°C. Achieving high efficiencies in this temperature range contributes strongly to high seasonal efficiencies.

› Largest part of heat output delivered at optimal efficiencies

› Less on/off operation when heat load becomes lower than the minimum capacity the heat pump can deliver, optimising efficiency and comfort

The combined effect of the Daikin Altherma weather-dependent set-point control and the Daikin Altherma inverter compressors maximises the efficiency at each outdoor temperature, assuring stable room temperatures.

1 Weather-dependent set-point control: Daikin Altherma maximises efficiency at every outdoor temperature through its weather-dependent set-point control. This control logic will always keep the water temperatures as low as possible, to maximise the heat pump efficiency for each specific outdoor temperature. This results in:

› Higher heat pump efficiency with lower water temperatures

› No unnecessary overheating, thereby deliver-ing the temperatures required

› Continuous heating at lower water tempera-tures, providing stable room temperatures

2 Inverter technology: lowering the compressor frequency with increasing outdoor temperatures, thus increasing the efficiency

d. Smart heating control

e. Optimal use of energy limiting electrical inputs of auxiliary components

› No bottom plate heater needed on 4-8kW class › Low-capacity bottom plate heater on 11-16kW class

(ERLQ-C series), only operating during defrost cycles, results in 90% less electricity consumption when compared with standard thermostatic controlled bottom plate heaters.

› Thanks to all these improvements, COP of up to 5.2* is reached

The low capacity unit with its high modulating range offers optimal efficiency in most relevant outdoor temperature ranges by combining compressors and plate heat exchangers that have been specifically designed for smaller heat loads. This is designed to meet the needs of the new-build house market in Europe, which is moving towards smaller heat loads due to:

The new-build house market in Europe is moving towards smaller heat loads, due to :

1. Growing importance of low-energy houses

2. Stronger legislation on energy consumption in new residential constructions (e.g. EPBD regulations)

3. Decreasing size of new-build houses

4. EU Member States planning to reach their 20-20-20 targets

Daikin Altherma low temperature offers a full product line-up with a specifically dimensioned heat pump system (compressor, modulating range, plate heat exchanger, …) to deliver the required capacities for the house, with the best possible efficiencies.

Daikin Altherma low capacity unit is developed and dimensioned to reach optimal efficiencies at the most relevant temperature range, thanks to its high modulating range.

A consistent energy label across Europe

The Ecodesign Directive for heat generators and water heaters requires them to carry energy labels which are common across all EU member states. The principle behind this label is already well-known from refrigerators, washing machines and TV sets. Devices and appliances are currently split into efficiency classes on a scale from A++ to G. Dark green represents the highest level of efficiency, dark red the lowest.

Be on the safe side with Daikin

All Daikin units are tested and meet the criteria of the Ecodesign Directive. Our energy labels reliably show the precise efficiency class, both for individual products up to A++ and for packages up to A+. Perfectly matched in terms of their individual components, our complete systems provide both maximum comfort and peace of mind – for dealers, installers and end users.

Tank temperature up to 55°C with heat pump only, up to 60°C with the standard back-up heater of the heat pump module.

High hot water volumes

The following volumes can be achieved with only one heat-up cycle.

› Hot water volume of 300l available at 40°C (sufficient for six showers) without electrical assistance (260l tank, tank temperature 50°C, cold water temperature 10°C, one heat-up cycle).

› Hot water volume can be increased to 375l using the standard back-up heater (260l tank, tank temperature up to 60°C).

c. Best solution for domestic hot water heating: high efficiency – high comfort

Smart control

Daikin Altherma uses smart controls to heat the domestic hot water tank, maximising efficiency and comfort for the end-user. The combination of the schedule and reheat functions guarantees minimum electrical input and ensures constant availability of hot water.

› Schedule function: heat the tank to a pre-set temperature at a specified time. Can be repeated four times per day, with the possibility of setting two different tank temperatures (storage comfort and storage economic).

› Reheat function: when the tank temperature goes below a specified minimum reheat temperature, Daikin Altherma switches automatically to domestic hot water heating, heating the tank to a specified maximum reheat temperature.

› Both functions can be used individually or in combination to provide the best efficiency and maximum comfort. The schedule function can heat the tank during the night, with the low electricity tariff, up to a relatively low temperature (e.g. 50°C without electrical assistance). When higher hot water consumption occurs during the day (lowering the tank temperature to the minimum reheat temperature) the heat pump will switch automatically to domestic hot water heating with the reheat function to guarantee the constant availability of hot water. Thanks to the large coil surface of the tank (1.56m2) heating the tank with the schedule or reheat functions occurs very quickly.

d. Quick and easy commissioning

e. Easy serviceability

At the first start-up, a quick configuration wizard will guide you smoothly through the commissioning process. Via a series of short questions, the set-up of basic parameters will automatically be completed. Fine-tuning these parameters remains possible using the menu-based navigation. As a result of the quick configuration wizard, only the parameter settings relevant to the installation are shown in the menus. The irrelevant parameters will be hidden and thus inaccessible.

You can download the parameters to a PC as a back-up or for duplication on similar installations. If preferred, you can prepare the parameter settings beforehand and upload them to the unit during commissioning.

Before the actual test-run of the unit, an actuator test mode allows all the wired components to be activated one by one. This makes it easy to do a quick and easy check of all connections and wiring to ensure correct operation. An automatic screed-drying function can be activated: it proceeds through a gradual heat-up of an under-floor heating system to avoid cracks in the floor during first use. Individual and easy-to-programme schedule timers – for heating, cooling, domestic hot water operation and recirculation, noise-sensitive operation and electrical booster heating – adjust operation to match the end-user’s typical daily schedule. After the commissioning, you can restrict access to the installer’s menu (manually or automatically after one hour) to avoid wrong manipulation of the unit by the end-user.

27

In case something goes wrong, full-text error messages guide the end-user to take appropriate action to try and resolve the problem. If the problem persists and a site intervention is necessary, the service engineer will be able to review the last 20 error occurrences, for simple diagnosis of the problem.

Detailed information on the operational conditions of the unit – such as the running hours of the different elements, operating temperatures or number of starts – can easily be read out from the extended end-user’s menu.

The user interface itself is equipped with a temperature sensor and can be installed remotely from the Daikin Altherma low temperature indoor unit.

› Installed on the unit: it allows quick and easy access to the unit’s operating information and settings.

› Installed remotely (e.g. living room): it also acts as a room thermostat – but with advanced features that provide more stable room temperatures, increased efficiency and operation life cycle. A second optional interface can still be installed on the unit for service purposes.

Room thermostat:

The Daikin user interface can be installed in the living room using the room thermostat function, which can additionally lower or raise the set-point water temperature depending on the actual room temperature, to even better match the set-point room temperature.

2.Integrated solar unit and domestic hot water tank

maximising renewable energyand offering top comfort for hot water preparation

28


The integrated solar unit uses free

energy from the sun to provide

domestic hot water and space

heating support. Solar energy and

heat pumps complement each other

ideally in this application. Depending

on your customer’s needs, you can

offer an a pressureless (drain-back)

or pressurised solar system. The

integrated solar unit based on a

lightweight plastic tank and can be

combined with a secondary heat

source. And end users can control the

unit easily via a smartphone app.

29


The integrated solar unit uses free energy from the sun to produce domestic hot water and space heating.

Thanks to the extremely high efficiency of our flat solar collector up to 80% of solar energy can be converted into usable heat. In this application solar energy and heat pumps complement each other ideally: the heat pump adds the required amount of heat to the system to meet the demand.

Offer a drain-back or pressurised system depending on your customers‘ needs.

Drain-back solar system (with EHSH(X)-A) If the constructional conditions permit, recommend the direct drain-back system. In this system, the water in the storage tank is supplied directly and without heat exchanger to the solar collectors, heated and then stored. This process considerably increases the efficiency of the entire system, especially the solar collectors. Because the system is not pressurised, there is no need for an expansion tank, pressure relief valve, pressure gauge or heat exchanger.

A fully-automatic controller independently manages the solar system to provide optimum use of solar energy. The solar collectors are only filled if there is sufficient energy from the sun, and if the thermal storage tank can absorb the heat. When energy from the sun is insufficient, or the thermal storage tank can not absorb more heat, then the feed pump switches off, and the entire solar system drains into the thermal storage tank. Because of this process, this system does not require antifreeze. The connection pipes in the building and on the roof must be installed with a constant gradient. If a constant

gradient is not possible, then a pressurised solar system is a better solution.

Pressurised solar system (with EHSH(X)B-A) The pressurised solar system is easy to install and suitable for any application, in any building. It operates efficiently and safely at all pipe lengths and feed heights. The structure of the solar thermal storage tank is engineered so that an additional plate heat exchanger is not necessary. A bivalent heat exchanger for pressurised solar or other heat sources is already incorporated, making the system simple and flexible.

b. Lightweight tank with exceptional hygienic benefits

c. Bivalent option: combinable with a secondary heat source (EHSH(X)B-A only)

d. Easy app control

Heat from other sources can also be efficiently stored in the indoor unit. The solar system can be supported by oil-fired and gas-fired boilers, pellet-fired boilers or wood-fired stoves with boilers for heating and

hot water generation. If you are not installing a solar system from the beginning, it can be fitted quickly and easily at any time afterwards.

1. Control with the app

Simple, consistent handling can be carried out via a smartphone app. You’ll find it easy to use, thanks to the intuitive menu navigation and control.

2. Clear display and easy modification

The display shows values and parameters in clear text. All operating modes, timer programmes and operating parameters can be set and modified quickly.

3. Simple controller for easy regulation

The water temperature for heating is regulated according to the outdoor temperature. The controller automatically detects winter and summer, and switches the heating mode on and off to suit demand. The controller is easy and intuitive to operate and can be extended with a room controller, allowing the end user to conveniently control and monitor the heating system.

there is enough solar heat. › The pump switches on briefly and fills the

collectors with storage tank water. › The fully-automatic controller manages the

solar system independently to provide optimum utilisation of the solar energy

› The system drains the water to the storage tank when not needed.

› No expansion tank, pressure relief valve, pressure gauge, heat exchanger and antifreeze required.

Pressurised solar system › System is filled with heat transfer fluid with

the correct amount of antifreeze to avoid freezing in winter.

› System is pressurised. › Operates safely and efficiently with any length of

pipe or feed height. › A bivalent heat exchanger makes the system
