Product Description

Heat pumps with environmentally friendly refrigerant R-744 (CO2)

Advantages of using CO2 as a refrigerant

As CO₂ is a natural, non-HFC refrigerant, it boasts an ozone depletion potential (ODP) of zero, and a global warming potential (GWP) of 1.

Conversely, traditional HFC refrigeration systems adversely impact climate change in two distinct ways: direct and indirect contribution. Direct contribution results from the release of refrigerants into the atmosphere.

Indirect contribution refers to the energy used to operate traditional refrigeration equipment. Essentially, the less energy required to operate the equipment, the lower the impact on the environment.


In order to provide answers in the case of special requirements, it is often necessary to identify solutions that deviate from the standard. Ecodan heat pump systems, which can be used for heating, cooling and domestic hot water (DHW) production, use the refrigerant R410A – in contrast, the QAHV uses the refrigerant R744. After all, pure hot water heat pumps, which are tasked with generating particularly high hot water temperatures, have to meet very different requirements of their own.



Behind the type designation R744 is the natural refrigerant CO2. Carbon dioxide (CO2) is almost the ideal refrigerant in ecological and safety-related terms as it has an ozone depletion potential (ODP) of 0. In addition, it is non-toxic, non-flammable and chemically inert – properties that render recovery and disposal unnecessary
