forapartmentbuildingsand

collectivehousing

Apartment buildings are the most common form of new home

construction in Europe, with twice as many apartment units being

built than single-family homes. Such buildings deserve high efficient

heating systems. To meet this need, Daikin is introducing Daikin

Altherma Flex Type. This comfort system heats, cools and produces

domestic hot water simultaneously by making optimal use of our

VRV® and cascade technology. Daikin Altherma Flex Type represents

a further extension of our heating product range that until now has

targeted new and refurbished single-family dwellings. Expansion

into the apartment and collective housing segment confirms Daikin’s

position at the cutting edge of residential comfort technology and

represents a further realisation of our goal to provide the market with

the best in turnkey residential comfort.

Daikin has more than 50 years of experience with heat pumps, and

supplies more than one million of them to homes, shops and offices

each year. Over 100,000 Daikin Altherma units have been installed

throughout Europe. Such success is only possible from a market

leader that can guarantee the highest levels of service and quality!

modularflexibility

The Daikin altherma makes use of Daikin’s renowned VrV®

technology. multiple indoor units can be connected to a single

outdoor unit. a combination of proportional integral Derivative

controlled compressors and electronic expansion valves in the

outdoor unit continuously adjust the circulating refrigerant

volume in response to load variations in the connected indoor

units.

This allows the indoor units to operate independently of each

other,assuringtotalflexibility.eachapartment retainscontrolof

itsownheating,hotwaterandcooling.

invertercompressors

Daikin altherma owes its remarkable low energy consumption

to a unique combination of highly efficient inverter-controlled

Daikin compressors with a variable operating point.This allows

capacitytobeexactlymatchedtotheactualheatingdemandof

the outdoor unit also means maximum comfort and minimum

DaikinaLTHermaFLexType:THeFLexibLeHeaTingSOLuTiOnFOraLL

Daikin Altherma represents added value for any

APARTMENT OWNER, with its innovative combination

of heating, cooling and domestic hot water production

in a single system. It improves on current heating system

performance - it makes use of renewable energy, 2/3 of the

heat is coming from the air outside - cools when and where

necessary, and includes a heat recovery system.

Its efficient, environmentally aware air-to-water heat pump

technology makes today’s apartment buildings more

environmentally sustainable, with lower running costs,

reduced CO2 emissions, and reduced primary energy use.

Daikin Altherma Flex Type is the first product on the market

that fully allows the use of renewable energy source for

apartment applications.

The modular design of Daikin Altherma Flex Type allows

CONSULTANTS and ARCHITECTS to incorporate the

system in any development project. A typical installation

includes 1 outdoor unit (from 23 to 45 kW) for up to

10 apartment units. Multiple outdoor units can be installed

for larger applications.

The outdoor unit extracts heat from the outdoor air,

raises and transfers it at intermediate temperature to the

individual indoor units (6 and 9 kW). The small footprint

indoor unit raises the temperature further and feeds

heated water to emitters. Aditionally, the unit can provide

cooling. The ideal heat emitter is the Daikin heat pump

convector, which offers high capacity heating & cooling in

a compact unit and low sound levels.
