Abstract
First and second refrigerating circuits respectively cause first and second adsorbing bodies to alternately adsorb and release first and second coolants. In the first refrigerating circuit, when the first adsorbing body is heated, it releases the first coolant. The released first coolant is cooled, and discharged through an expansion valve so that a part of the first coolant is liquefied. The resultant latent heat of vaporization can be utilized to cool an object to be cooled. Thereafter, the first coolant is adsorbed when the first adsorbing body is cooled. In the second refrigerating circuit, when the second adsorbing body is heated, it releases the second coolant. The released second coolant is cooled by a liquefied-gas-type cooler, and discharged through an expansion valve so that a part of the second coolant is liquefied. The resultant latent heat of vaporization is utilized to cool the first adsorbing body of the first refrigerating circuit. Thereafter, the second coolant is adsorbed by the second adsorbing body. The liquefied-gas-type cooler cools the second coolant by utilizing the latent heat of vaporization of a liquefied gas. Thus, the amount of the second coolant liquefied after being discharged through the expansion valve in the second refrigerating circuit is increased.
