Kind Code:
A1
Abstract:
Disclosed in the present application are an air conditioner control method, an air conditioner control apparatus and an air conditioner having the same, the air conditioner being operating in a low-temperature hybrid mode. The method comprises: determining that an outdoor heat exchanger of an air conditioner operates in an evaporator state; collecting a state parameter for identifying a refrigerant state, and acquiring a state signal of a refrigerant of a refrigerating indoor machine according to the state parameter, wherein the state parameter at least comprises an overheat degree of the refrigerating indoor machine; and adjusting an opening degree of an electronic expansion valve of an outdoor machine according to the state signal of the refrigerating indoor machine. The method can adjust an opening degree of an electronic expansion valve of an outdoor machine according to a state signal of a refrigerating indoor machine when an outdoor heat exchanger of an air conditioner operates in an evaporator state, effectively improving control reliability, expanding the range of reliable operation of a system, and effectively addressing the problem of reasonable distribution of refrigerant between a refrigerating indoor machine and an outdoor machines under a low-temperature condition.
