CO2 heat pumps function the same as heat pumps using conventional refrigerants. By using CO2 as the refrigerant, the heat pumps can operate more efficiently in the high temperature range and more efficiently in low ambient temperatures.
With a maximum outlet temperature of 90°C, CO2 heat pumps can be used to produce domestic hot water.
CO2 heat pumps in combination with buffer tanks can also be used to replace existing gas boilers for space heating.
Existing central heating installations usually require a minimum supply water temperature of 80°C. CO2 heat pumps are therefore an excellent device to make existing buildings more sustainable.
By combining central heating with hot water production, the Seasonal Performance Factor (SPF) gets even better.
CO2 heat pumps are suitable for collective heating in apartment buildings, small district heating systems, swimming pools, sports accommodation, sanitary hot water production in hotels and holiday parks.
