To solve various problems due to delay in initial rise in starting an operation and dew condensation, as in a conventional adsorption type heat pump, dew condensation is found on an adsorbent and an adsorption core adsorbing vapor in stopping an operation.
A refrigeration system additionally includes a refrigerant tank 5 for recovering a refrigerant inside of a refrigeration cycle in stopping an operation to prevent dew condensation inside of the refrigeration cycle, a solenoid opening/closing valve 6 opened in returning the refrigerant from the refrigeration cycle to the refrigerant tank 5, a solenoid pressure equalizing valve 7 opened in returning the refrigerant from the inside of the refrigeration cycle to the refrigerant tank 5 to equalize a pressure in an evaporator 4 and a pressure in the refrigerant tank 5, and an electric heater 8 for heating the refrigerant in the refrigerant tank 5 to make the pressure in the refrigerant tank 5 higher than that in the evaporator 4 in returning the refrigerant from the refrigerant tank 5 to the refrigeration cycle in starting an operation.
