動車用冷房装置。 In an automobile cooling system, refrigerant gas compressed by a compressor is sent to a condenser, adiabatically expanded by an expansion valve, and then supplied to an evaporator.A temperature sensor detects the temperature of the refrigerant before and after the evaporator, and a temperature sensor detects the flow rate of the circulating refrigerant. a flow rate detector to detect;
An automobile cooling system comprising: a control device which receives signals from these detectors and controls the expansion valve so that the product of the refrigerant temperature difference before and after the evaporator and the refrigerant flow rate is maximized.
