thermeco2 high-temperature heat pumps with cooling function shine in a government facility
In the public sector, two thermeco2 high-temperature heat pumps with cooling function are proving their worth in the energy-efficient provision of heating and cooling using CO₂ (R-744, GWP = 1) as refrigerant.

Cooling-heating-coupling- thermeco2 flexibly supply the government institution with temperatures ranging from 10 degrees Celsius to over 75 degrees Celsius.
- The heat pumps use the non-fluorinated refrigerant CO₂ (R-744, GWP = 1), which significantly reduces the global warming potential compared to conventional HFC refrigerants.
A state institution has chosen to install heating technology as part of its building operation and energy management approach. This is precisely what this project demonstrates, in which our experts at ENGIE Refrigeration are making targeted use of two thermeco2 high-temperature heat pumps with cooling function. The challenge: to find a solution that meets complex temperature requirements, provides both heating and cooling, and uses a natural refrigerant – a combination that is technically demanding and particularly important in the public sector. Our thermeco2 high-temperature heat pump with cooling function confidently meets all these criteria and masters the temperature gap between cold water at ten degrees Celsius and hot water at more than 75 degrees Celsius. Thanks to heat-cold coupling, thermeco(2)performs particularly efficiently.
Heat pumps with cooling function: sustainably effective
And the heating solution scores with further advantages: the non-fluorinated refrigerant CO₂ (R-744, GWP = 1) combines a low global warming potential, high energy efficiency (COP/SCOP) and cost-effectiveness – the ideal starting point for modern cooling and heating solutions. Among non-fluorinated refrigerants, CO₂ is the only one that is neither flammable nor toxic. This facilitates safe and legally compliant use in various applications. The fact that high-temperature heat pumps with a cooling function do not leave the waste heat generated during the cooling process unused, but use it directly for heating purposes, this demonstrates the efficient use of waste heat: no energy is lost during the cooling process, but is directly recovered for heating purposes. This makes them suitable not only for government institutions, but also for all other applications where waste heat is generated throughout the year and both heating and cooling are required – whether for building heating, industrial processes or drinking water heating. Ultimately, this practical example shows that technical innovation and responsibility for future generations are not mutually exclusive, but complement each other perfectly. Our thermeco2 high-temperature heat pumps with cooling function provide tangible proof of this!
