When the indoor and outdoor temperature difference is less than 5 ℃ and the indoor temperature is 26 ℃, the outlet water temperature of the air energy heat pump indoor unit 2 is 15 ℃. When the outdoor temperature exceeds 30 ℃ and the indoor and outdoor temperature difference is less than 5 ℃, the outlet water temperature of the air energy heat pump indoor unit 2 is in linkage of 1:1 inverse reduction according to the outdoor temperature, namely, the outlet water temperature of the air energy heat pump indoor unit 2 is reduced by 1 ℃ when the outdoor temperature rises by 1 ℃, and the limit value is 5 ℃. If the indoor and outdoor temperature difference is a negative value, the air energy heat pump indoor unit 2 stops working. Under the refrigeration mode, the temperature of the water inlet of the coupling tank is lower, the water inlet temperature of the coupling tank can reduce the temperature of return water in the coupling tank to a certain degree, and the temperature difference between the water inlet temperature and the return water temperature of the coupling tank is reduced.
