冷凍装置。 In a refrigeration system, the refrigerant circulates through a compressor, a condenser, a throttle device, and an evaporator in this order during cooling operation, and the refrigerant circulates in the opposite direction to the above during defrosting operation.
At least two throttling devices with different flow resistances are installed in parallel on the refrigerant inlet side during defrosting operation of the condenser, and a signal from a pressure switch is activated by detecting high pressure during defrosting operation. A refrigeration system characterized in that a solenoid valve that is opened and closed is provided in series with the above-mentioned throttling device that has a smaller flow resistance.
