Abstract: A heat recovery air-conditioning hot water system and a refrigerant flow control method therefor. The heat recovery air-conditioning hot water system includes a compressor, a condenser, heat exchangers, an indoor unit, a first throttling device, a second throttling device, a first reversing valve, and a second throttling device, wherein the first reversing valve is used to control the refrigerant switching of the indoor heat exchanger, so as to realize the switching of cooling and heating modes; the second reversing valve is used to control the refrigerant switching of the outdoor heat exchanger, so as to realize the operation switching of cooling and heating modes of the outdoor heat exchanger; and an exhaust pipe of the compressor is respectively connected to the first reversing valve, the second reversing valve, and the water-side heat exchanger by means of a water-side high-pressure air pipe.
