In particular implementation, the invention can calculate the heat exchange quantity of the jet micro-channel radiator 14 and the soaking plate radiator 19 by testing the inlet and outlet pressure and the temperature of the jet micro-channel radiator 14 and the soaking plate radiator 19 and the flow parameters of the flowmeter 10, and judge the good and poor heat exchange performance of the jet micro-channel radiator 14 and the soaking plate radiator 19 according to the heat exchange quantity of the jet micro-channel radiator 14 and the soaking plate radiator 19. That is, the higher the heat exchange amount of the jet micro-channel radiator 14 and the soaking plate radiator 19, the better the heat exchange performance of the jet micro-channel radiator 14 and the soaking plate radiator 19, and the lower the heat exchange amount of the jet micro-channel radiator 14 and the soaking plate radiator 19, the worse the heat exchange performance of the jet micro-channel radiator 14 and the soaking plate radiator 19.

Therefore, for the present invention, the pressure value of the refrigerant at the inlet and outlet ends of the jet micro-channel radiator 14 can be obtained by measuring the differential pressure sensor 13 at the inlet and outlet ends of the jet micro-channel radiator 14, and the corresponding specific melting values (i.e. the heat value contained in the unit mass of the refrigerant) of the refrigerants at the inlet and outlet ends of the jet micro-channel radiator 14 and the soaking plate radiator 19 can be obtained directly from the thermal property chart of the refrigerant by measuring the two temperature sensor groups (the first inlet temperature sensor group 12, the first outlet temperature sensor group 16 and the second inlet temperature sensor group 17 and the second outlet temperature sensor group 20) respectively at the inlet and outlet ends of the jet micro-channel radiator 14 and the soaking plate radiator 19, so that the specific type of the refrigerant used in the present invention can be obtained according to the specific type of the refrigerant used at the inlet and outlet ends of the jet micro-channel radiator 14 and the soaking plate radiator 19, and the corresponding specific melting values (i.e. the heat value contained in the unit mass of the refrigerant) of the refrigerants at the inlet and outlet ends of the jet micro-channel radiator 14 and the soaking plate radiator 19 can be directly inquired.
