The method comprises the steps that when a water side heat exchanger of the household water machine operates in a refrigeration mode, the refrigerant pressure in the water side heat exchanger is obtained; and when the refrigerant pressure is smaller than the first preset threshold value, the unit comprising the water side heat exchanger is controlled to exit the refrigeration mode. According to the control method, the unit comprising the water side heat exchanger can be controlled to quit the refrigeration mode in time according to the pressure of the refrigerant in the water side heat exchanger of the household water machine in the refrigeration mode, the situation that the low pressure of the low-temperature refrigerant is too low, the evaporation temperature of the low-temperature refrigerant is reduced, and consequently water in the water side heat exchanger which exchanges heat with the refrigerant is frozen is prevented, and therefore the user experience is improved. And the water side heat exchanger can be effectively protected, so that the service life of the household water machine is prolonged.
本申请公开了在户式水机的水侧换热器运行在制冷模式时,获取水侧换热器内的冷媒压力;在冷媒压力小于第一预定阈值时,控制包含水侧换热器的机组退出制冷模式。本申请的控制方法,可根据制冷模式下户式水机的水侧换热器内部冷媒的压力,控制包含水侧换热器的机组及时退出制冷模式,防止低温冷媒的低压过低导致其蒸发温度降低,从而导致与冷媒进行热交换的水侧换热器内的水结冰,如此,可以有效保护水侧换热器,从而延长户式水机的使用寿命。
