Absorption heat-pump

 

Absorption heat pumps use high temperature heat to regenerate refrigerant that can evaporate at low temperatures and thus use energy with low potential. 1 MW of high temperature driving energy allows 700 kW of heat to be obtained from a low temperature (15 ° C) heat source. Thus, 1.7 MW of heat is given to the consumer at a temperature of 60 ° C (efficiency factor 1.7).
