Refrigeration characterized in that an expansion valve for a gas cooler and an expansion valve for a subcooler are provided, and an electromagnetic valve that detects the temperature of the brine and opens and closes the brine is provided in front of the expansion valve for the gas cooler to control the amount of refrigerant. Device.
