Beschreibung
Zusammenfassung:	The invention relates to the field of heat pumps, in particular to a cascade heat pump system. The cascade heat pump system comprises a first compressor, a multi-way reversing valve, an evaporator, a first heat exchanger, an evaporative condenser, a second compressor and a second heat exchanger; the evaporative condenser is provided with an evaporation side and a condensation side which are in heat exchange connection. The first heat exchanger is provided with a first side and a second side which are in heat exchange connection. The second heat exchanger is provided with a third side and a fourth side in heat exchange connection; the first compressor, the multi-way reversing valve, the evaporator, the first side of the first heat exchanger and the condensation side of the evaporative condenser are connected to form a primary loop. The second compressor, the evaporation side of the evaporative condenser and the third side of the second heat exchanger are connected to form a second-stage loop. The cascade heat
