HEAT PUMP COMPRISING A COOLING MODE

摘要

A heat pump comprising a cooling mode includes a cooling evaporator coupled to an advance flow and a backflow. The cooling evaporator is brought to a pressure such that a vaporization temperature of the working liguid in the backflow is below a temperature of an object to be cooled to which the backflow may be thermally coupled. In this manner, an area having vapor at high pressure is generated. This vapor is fed into a dynamic-type compressor which outputs the vapor at a low pressure and provides electrical energy in the process. The vapor at low pressure is fed to a cooling liquefier which provides vapor liquefaction at a low temperature, this temperature being lower than the temperature of the object to be cooled.
