Beschreibung
Zusammenfassung:	The invention relates to a variable-frequency air source heat pump system capable of discharging water at double water temperatures. The variable-frequency air source heat pump system comprises an outdoor unit, a first refrigerant-water heat exchanger unit and a second refrigerant-water heat exchanger unit, wherein the outdoor unit comprises a compressor, a four-way reversing valve and an air side heat exchanger, and the four-way reversing valve and the air side heat exchanger are sequentially connected with the compressor; the second refrigerant-water heat exchanger unit comprises a forward refrigerant side heat exchanger and a reverse temperature adjusting refrigerant heat exchanger which is connected with the forward refrigerant side heat exchanger in series through a water path, wherein the reverse temperature adjusting refrigerant heat exchanger is connected with refrigerant pipelines at the two ends of the air side heat exchanger through refrigerant pipelines correspondingly, one end of the forward refr
