Abstract

Provided is a heat pump and a method for operating a heat pump. In a heating mode, the heat pump comprises a refrigeration cycle including connected in a loop by fluid lines and in succession: a compressor, a first heat exchanger, a third heat exchanger, a second expansion valve, and a second heat exchanger. The refrigeration cycle further comprises an internal heat exchanger having a first conduit and a second conduit being in heat exchanging contact, wherein the first conduit is part of the fluid line between the third heat exchanger and the second expansion valve, and the second conduit is part of the fluid line between the second heat exchanger and the compressor, wherein the third heat exchanger is configured to reduce a temperature of the refrigerant provided from the first heat exchanger to the internal heat exchanger by giving off heat to a physical medium.
