PURPOSE: To provide a small-sized adsorption agent tank and to increase a cooling capability by a method wherein a flow passage for use in circulating refrigerant to be cooled at a load side is provided with a bypass flow passage for bypassing a part of the refrigerant to be cooled around an evaporator and circulating it in response to a temperature at the load side and with bypassing damper.
CONSTITUTION: A part of duct circulation air is branched to flow in a bypassing pipe 613 by a damper 614 at an upper end of a bypassing pipe 613 bypassing a duct 611 for medium to be cooled, i.e., air. A liquid surface of the cooling medium within an evaporating pipe of an evaporator 600 is placed at a slight upper level of a liquid surface of a condensor 500. With such an arrangement, since a volumetric flow rate of air flowing in the duct 611 is high, a heat transfer coefficient or a heat exchanging amount is varied in response to a variation of air flow rate flowing in the evaporator with a damper, resulting in that a refrigerant load can be controlled to show a set temperature. At that time, it is sufficient to control only a bypassing amount while an entire circulation fluid being kept at a constant value.
