the first determining module is specifically configured to: determining the flow Q of the circulating water pump according to the external environment temperature Tao, wherein the flow q=k2 of the circulating water pump is equal to Q; wherein Q is the rated flow of the circulating water pump; k2 is a flow coefficient, and the flow coefficient K2 is positively correlated with the external environment temperature Tao;
the second determining module is specifically configured to: determining the operation frequency f of the compressor according to the external environment temperature Tao, and determining the opening of the electronic expansion valve according to the operation frequency f of the compressor;
the compressor operating frequency f is positively correlated with the external environment temperature Tao, and comprises:
compressor operating frequency f=k 1 * F, performing the process; wherein F is a compressorRated operating frequency; k (K) 1 Is the frequency coefficient, the frequency coefficient K 1 Is positively correlated with the external ambient temperature Tao;
when the external environment temperature is less than Tao at 32 ℃, the frequency coefficient K 1 The value of (2) is 1.38-1.74, and the flow coefficient K 2 The value of (2) is 1.76-2.36.
