Abstract
A system for household-related heat recovery from waste water includes a compression heat pump having a compressor for a coolant, a condenser, and an evaporator. Disposed between the condenser and the evaporator is an expansion valve, and a temperature probe is arranged on the evaporator at a location at which coolant is injected. A switching valve switches over a flow resistance of the expansion valve between two fixed flow resistance values. Below a predetermined temperature at the temperature sensor, the switching valve switches over to low flow resistance of the expansion valve and above the predetermined temperature, the switching device switches to a higher flow resistance of the expansion valve.
