A refrigerating apparatus capable of reducing the start noise of the compressor comprises a compressor 1, a condenser 2, a capillary tube 4, and an evaporator 6, serially connected by piping to form a closed loop. The apparatus further comprises a solenoid valve 3 installed between the outlet of the condenser 2 and the capillary tube 4 and a control unit C controlling the compressor 1 and the solenoid valve 3. The control unit opens and closes the solenoid valve 3 in response to the operation and stop of the compressor 1 and in particular closes the sole...
A refrigerating apparatus comprising: a compressor, a condenser, an expansion device, and an evaporator, serially connected by piping to form a closed loop; a first valve located between an outlet of the condenser and the expansion device; a second valve located between the compressor and the evaporator for preventing the refrigerant from flowing back from the compressor to the evaporator when the compressor stops; and a control unit controlling the compressor and the first valve, said control unit opening and closing the first valve in response to the o...
