- the heat sink circuit is formed by means of the heat sink feed and the heat sink return.
- the evaporator which is thermally coupled to the heat sink return, allows a reduction in the temperature of the heat sink return.

In other words, advantageously the temperature of the heat source may be further utilized.
- the heat pump may use a working fluid with R1233zd, R1336mzz, butane, cyclopentane and/or with a fluoroketone and/or a mixture of said substances.
