Air conditioner system and evaporation temperature control method thereof

The invention discloses an air conditioner system which comprises a compressor, an outdoor heat exchanger and indoor heat exchangers connected in parallel. The compressor, the outdoor heat exchanger and the indoor heat exchangers are sequentially connected to form a refrigerant circulation loop. The side, close to the outdoor heat exchanger, of each indoor heat exchanger is provided with a first electronic expansion valve. The side, close to the compressor, of each indoor heat exchanger is provided with a second electronic expansion valve. The air conditioner system further comprises a controller. When the controller obtains the information that the practical superheat degree of the indoor heat exchangers is not equal to the preset superheat degree, the opening of the first electronic expansion valves is correspondingly adjusted according to the difference value between the practical superheat degree and the preset superheat degree; and or when the controller obtains the information that the practical evaporation temperature of the indoor heat exchangers it not equal to the preset evaporation temperature, the opening of the second electronic expansion valve is correspondingly adjusted according to the difference value between the practical evaporation temperature and the preset evaporation temperature. The invention further discloses an evaporation temperature control method of the air conditioner system. The evaporation temperature of multiple indoor units which are connected in parallel in the air conditioner system can be independently controlled.
