The Daikin Altherma Flex Type is todays answer to current and future issues associated with conventional heating systems such as increasing energy costs and unacceptable high environmental impact. With the Daikin Altherma Flex Type, 2/3 of the heat generated comes from the air, recognised as renewable energy source, which is free of charge! Daikin Altherma Flex Type achieves a typical seasonal COP of 3 in the moderate Western and central European climate. Compared to an oil boiler, this results in: Up to 36% less running costs* Up to 71% reduction of CO2 emissions* Up to 35% % reduction in primary energy use*
* Data calculated taking in account Belgian conditions: SCOP of 3, average energy prices 2007-2010, CO2 emission factor for electricity production

Modular system

One or more inverter-controlled outdoor heat pump units can provide heating, cooling and domestic hot water to an apartment building, with 1 outdoor unit combined with up to 10 indoor units. Outdoor units between 23 and 45 kW extract the heat from the outdoor air, raise it to an intermediate temperature and transfer this heat energy to the individual indoor units. A small footprint indoor unit is installed in each individual dwelling. It receives the heat energy from the central outdoor unit, raises the temperature further by means of a second (cascading) heat pump cycle and feeds heated or cooled water to emitters (underfloor elements, heat pump convectors and/or radiators as needed). Two classes of indoor units are available (6 and 9 kW), ensuring optimum efficiency for any size apartment. Multiple outdoor units can be installed for larger applications.

Space heating

Daikin Altherma Flex Type system uses two refrigerant cycles, R410A and R134a, to heat the water circuit. The purpose of a cascade system is to attain or work with pressures and temperatures which cannot be reached by using only one refrigerant cycle. The aim is to get best characteristics out of the two active cycles, both operating under their optimal conditions. The R410A refrigerant circuit has excellent characteristics with respect to low evaporating temperatures, while the R134a circuit has excellent characteristics for high condensing temperatures (see graph). Symbolic graph The advantages of cascade technology versus single refrigerant cycle heat pumps: Wide water temperature range (25C 80C): all types of heat emitters can be connected (under floor heating, convectors, radiators), but also compatible with existing radiators No drop of efficiency with increasing water temperatures, High capacities towards low ambient temperatures, down to -20C. No electrical heater required

compressor compressor

Domestic hot water heating
Thanks to the cascade technology, the Daikin Altherma Flex Type can reach water temperatures of 75C to heat up the domestic hot water tank, which makes it highly efficient for the production of domestic hot water.

Cooling

The second refrigerant cycle R134a can be bypassed to offer efficient cooling. The R410A refrigerant cycle is reversed, and the cool water circuit can be used to cool the rooms. High cooling capacities with water temperatures down to 5C, in combination with Daikin heat pump convector or Daikin fan coil units Under floor cooling is possible, with water temperatures down to 18 C Heat from cooling operation can be recovered to heat the domestic hot water tank
Domestic hot water can be produced up to 75 C, without the assistance of an electric heater No electric heater required for Legionella disinfection COP of 3.0 for heating from 15 C to 60 C Heat-up time from 15 to 60 C in 70 minutes (200L tank) Equivalent hot water volume of 320L at 40 C (without reheat) for a 200L tank at a tank temperature of 60C. Higher volumes of equivalent hot water are available with the 260l tank, or using a higher tank temperature.

Modular flexibility

The Daikin Altherma makes use of Daikins 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, assuring total flexibility. Each apartment retains control of its own heating, hot water and cooling.
Daikin compressors with a variable operating point. This allows capacity to be exactly matched to the actual heating demand of the building. The ability to optimally control the heat capacity of the outdoor unit also means maximum comfort and minimum energy consumption.

Heat recovery

Heat absorbed while cooling one apartment, can be recovered instead of being simply released into the air. This recovered heat can be used for domestic hot water production in the same apartment for space heating and domestic hot water production in other apartments Maximum use is made of available energy, thus reducing electricity costs.

Inverter compressors

Daikin Altherma owes its remarkable low energy consumption to a unique combination of highly efficient inverter-controlled
Small footprint, quick installation
The domestic hot water tanks in the Daikin Altherma Flex Type range are designed to be stacked on the indoor units. The heat pump indoor units themselves are fully equipped with all the required hydraulic components, and thus can be connected directly to the heat distribution system. Advantages: Small footprint: less than 0.6 m2 per apartment, less than 0.9m wall width Reduce installer workload by use of quick-couplings
Installation of outdoor unit
The outdoor units are sufficiently compact to allow easy transportation. Thanks to their lightweight construction and vibration-free operation, floors do not need to be reinforced. Small refrigerant pipes and refnet piping options allow quick and easy installation of the Daikin piping system. Compared to regular T-joints, where refrigerant distribution is far from optimal, the Daikin REFNET joints have specifically been designed to optimise refrigerant flow.

Silent operation

Comfort is more than the perfect indoor climate. The use of a low noise inverter compressor in the indoor units means the units will produce less sound than standard household appliances such as washing machines, dishwashers or refrigerators. In addition, a low noise mode is available to further reduce the sound of the indoor unit.
Easy and flexible cost allocation
Since the individual heat pump indoor units in each apartment share the heat captured by a single outdoor unit, it might be even required to distribute the operational costs of the outdoor units fairly amongst all tenants. When cost allocation based on the actual energy consumption of each individual tenant is preferred over equal shares, each apartment can be equipped with heat metering equipment. A Daikin software tool allows you to calculate the correct share in the operational cost of the outdoor unit for each apartment based on the readings of the installed heat metering equipment, and taking into account additional consumption for cooling operation or savings due to heat recovery operation. This software tool accepts input from most industry standard heat metering equipment, which will also allow you to subcontract the cost allocation to any meter reading company.
Daikin heat pump convector:
the optimal heat emitter for apartments
The Daikin heat pump convector operates at typical water temperatures of 45C, which can be efficiently produced thanks to the Daikin Altherma cascade technology. The heat pump convector is therefore the ideal heat emitter for apartment applications, providing high comfort levels: Small dimensions compared to low temperature radiators: width is reduced with 2/3rd Low sound level, optimal for bedroom applications down to 19 dB(A) High-capacity cooling with water temperatures down to 6 C Heating / Cooling operation

All type of heat emitters can be connected to Daikin Altherma Flex Type, thanks to its wide water temperature range. Daikin Altherma Flex Type is able to work with multiple set points, allowing a combination of different heat emitters operating at different water temperatures. The set point of the indoor unit will be lowered in function of the actual demand of the various heat emitters, ensuring optimum efficiency at all times and under all conditions. ZONE 1 : TLw = 65C

DAI-EL

Perfluoro
Daikins high performance perfluoroelastomer (FFKM) is the most stable fluoroelastomer even in the harshest chemical environment. It exhibits resistance to chemicals that standard FKM cannot withstand, such as ketones, ethers, furan, amines, ammonia, and high-concentration alkaline media. Furthermore, DAI-EL Perfluoro is ready-to-go and does not require custom tooling because it already contains cure agent and fillers.

FKM Compound Products

A wide range of FKM compound products are available from Cri-Tech, Inc., a subsidiary of DaikinAmerica, Inc. The use of full-compound products could improve the manufacturing productivity by eliminating the capital-intensive process of mixing FKM polymer, acid acceptor, and fillers. It could also eliminate unwanted carbon contamination in the facility.

Appendix 1: DAI-ELTM for Fuel Hoses
DAI-EL are vinylidene fluoride base fluoroelastomers which provide good processability of hoses and good fuel resistance (permeability). DAI-EL has various fluorine content (from 66% such as DAI-EL G-755 to 73% ) fluoroelastomer which suitable for hoses.

Safe Handling*

1. Compounding agent and facility The common fillers and facilities for commodity rubber can be used for DAI-EL. The mixing mill needs to be cooled. Finely divided metallic powder or filler, such as aluminum and magnesium, or amine compounds of more than 10% should not be used as compounding agents for DAI-EL because such materials are known to decompose vigorously elevated temperature. Store the compound in a tightly closed package in a cool and dry place. Another milling before use is recommended when the compound is left for more than three days. Too tight a nip between the rolls in the mixing mill may cause scorching. Be sure to cool the rolls well whenever the compound is milled with tight nip. The work are should be adequately ventilated at all times because a small amount of toxic gasses (e.g. HF, acetone, methanol, acetaldehyde, methyl iodide and carbon monoxide) may be evolved during curing. A slight amount of hydrogen fluoride vapor may be produced during use at high temperatures (above 200C). The room should be well ventilated. Do not smoke in the work area as harmful vapors may be inhaled when cigarettes are exposed to the powder of DAI-EL. After handling the powder of DAI-EL, knock off any dust from your hair or clothing and wash your face and hands thoroughly before smoking. Do not incinerate DAI-EL as this can produce harmful vapors. Disposal should be done in accordance with local laws and regulations.
