To provide a method for operating an adsorption type refrigerating system capable of improving a coefficient of performance with an effective cost and size by decreasing the quantity of heat except that for desorbing a refrigerant upon its desorption.
A heat exchanger 3 has two areas 4 and 5 divided by a partition wall 1 including a first heat transfer surface for heating and cooling a solid adsorbing material on one surface and a second heat transfer surface coming into contact with a heating medium on the other surface. A solid adsorbing material 2 is held in the first heat transfer surface area 4. In an adsorption type refrigerating system, while the first heat transfer surface area 4 is connected to a condenser 14 and an evaporator 15 by using the heat exchanger 3, the heat source device 7 of the heating medium and a cooler 8 are separated from and connected to the second heat transfer area 5. The heating medium is condensed and liquefied by the second heat transfer surface of the cooled partition wall 1. The solid adsorbing material 2 is heated by the condensing heat to desorb refrigerant vapor and evaporate and vaporize cooled heating medium by the heated second heat transfer surface. The solid adsorbing material 2 is cooled by the evaporating heat to adsorb the refrigerant vapor by the solid adsorbing material and output cold heat from the evaporator 14 connected thereto.
