How does the Daikin Altherma 3 Integrated R32 air-water heat pump work?

In a few words, its operation is given by the presence of a closed circuit inside which there is a refrigerant fluid subject to cyclic changes of state, which precisely passes from the liquid phase to the vaporized one and vice versa. These changes obviously lead to variations in pressure and temperature, which occur first of all at the level of the evaporator where, by acquiring heat from the air, the heat pump is able to transform the fluid from liquid to vapor. At this point, using electrical energy instead, there will again be a transition to the liquid state at the level of the compressor and in this phase the machine gives up heat to the system, everything happens cyclically and ends by means of an expansion valve that allows the fluid to return to its initial conditions.

Considering the energy balance related to the operation of the heat pump, we realize that this is essentially positive, meaning that the share of thermal energy produced is at least 5 times higher than the expenditure of electricity. The advantage of being able to use the machine both in summer, to cool, and in winter, to heat, makes it one of the most convenient solutions in the domestic sphere, without considering the fact that everything can be associated with the presence of a photovoltaic system, which would further increase the above-mentioned convenience. Moreover, the non-use of combustion sources associated with the use of electricity that, as mentioned, can be self-produced by photovoltaics, brings the system in a framework of almost total cost reduction. We are therefore referring to solar thermodynamic, a system through which we combine the special features of heat pumps and a solar collector of thermal type, with a small solar panel, a compressor component and a tank for water.

High performance: The innovative R32 Inverter compressor of the Daikin Altherma 3 chiller, equipped with Bluevolution technology, combined with climate control, allows you to achieve high performance with lower operating costs. Already ready for Class A+++, the new Altherma 3 range achieves a nominal COP value of 5.1 at 7°C outside and 35°C supply temperature and a COP of 3.3 in domestic hot water production (EN16147). Capable of reaching flow temperatures of up to 65°C at high efficiency, Daikin Altherma 3 with R32 is suitable for both underfloor heating and radiators, and retains its renowned frost protection features down to -25°C for reliable operation even in the coldest climates.

 

Ease of installation: Ten years of experience in creating air-to-water heat pumps and more than 350,000 units installed throughout Europe have resulted in a new range that is easier and faster to install and use. Setup has been simplified with a new wizard that allows installers to configure the unit in just a few steps and get it up and running quickly. Unit configuration, based on system type and needs, can also be done remotely and then uploaded to the unit's electronic board on the day of installation via USB or SD Card.
