Abstract
The present disclosure relates to a method for operating a refrigerant circuit through which a refrigerant circulates, in which heat is transferred from a first heat source to the refrigerant in a first heat pump mode, and from a second heat source to the refrigerant in a second heat pump mode. Efficiency and heating capacity are increased therewith in that heat is transferred to the refrigerant simultaneously from both the first heat source and the second heat source in a combined heat pump mode. The disclosure also relates to an air conditioning system that contains a refrigerant circuit operated in this manner.
