Abstract: Included are: a cylindrical body (cylindrical portion 16) provided with a shaft portion (18); and a first valve body (11) that is in close contact with the shaft portion to close an opening portion (22) of the cylindrical body, and is separated from the shaft portion when pressure (P) in the cylindrical body rises to a threshold (Pth) or higher by gas that has entered the cylindrical body, to release the gas from the cylindrical body to the outside. The valve body includes a closing portion (40) that receives the pressure (P) of the gas in the cylindrical body. The pressure received by the closing portion (40) serves as a valve opening force. As a result, the discharge characteristics of the gas filling a case are improved to enhance a pressure regulation function.

Abstract: Heat is absorbed from a first heat emitter and a second heat emitter is cooled by an adsorption type refrigerator operating by that absorbed heat. When the amount of emission of heat of the first heat emitter exceeds a predetermined amount of heat, the heat absorbed in the heat medium by a first heat collector is discharged to the outside air by an outdoor unit without being supplied to the adsorbent of the refrigerator. On the other hand, when the amount of emission of heat of the first heat emitter falls below a predetermined amount, the heat medium which had been supplied to a first heat exchanger for heating the adsorbent is switched to return to the first heat collector without flowing to the outdoor unit.
