Abstract

PURPOSE:To reduce an electric power consumption by a method wherein overheated gas, flowing into an evaporator from the compressor while it is stopped, is intercepted to reduce the temperature rise of the evaporator. CONSTITUTION:The gas of refrigerant medium, discharged into an enclosed vessel 2, is flowed into second discharging port 21 and is flowed to the condenser of a refrigerating cycle from a discharging pipe 22 through an inflow path 23. A pressure in a cylinder chamber 11 and the same in the enclosed vessel 2 become equal by the stop of a compressing element 4 and a discharge valve 15 closes the first discharging port 14 and the second discharging port 21. Accodingly, the inflow of the overheated refrigerant medium gas through the cndenser of the refrigerating device is prevented while the compressor is stopped to prevent the temperature rise of the evaporator, therefore, the electric power consumption may be reduced.
