冷房装置。[Claims for Utility Model Registration] (1) A compressor that sends out refrigerant vapor in a compressed state, a condenser that condenses the refrigerant sent from the compressor, and a fixed expansion coefficient that expands the liquid refrigerant sent out from the condenser. an evaporator that evaporates the liquid refrigerant that has passed through the expansion means and then sends it out toward the compressor; one end of the refrigerant is connected to an accumulator installed in the middle of a low-pressure side pipe connecting the evaporator and the compressor; A bypass pipe is provided in the middle of the high-pressure pipe connecting the compressor and the condenser, a regulating valve is provided in the middle of the bypass pipe, and a low-pressure pipe is located between the accumulator and the compressor. A superheat sensor is installed on the way to measure the degree of superheat of the refrigerant just before it is sent to the compressor, and the opening degree of the regulating valve is adjusted based on the signal from this superheat sensor to control the superheat of the refrigerant vapor that is sent to the compressor. An automotive cooling system consisting of a controller that maintains the temperature at an appropriate level. (2) The automobile cooling system according to claim 1, further comprising a fluid motor for driving a cooling fan provided in the middle of the bypass pipe line.
