PROBLEM TO BE SOLVED: To realize prevention of device breakage and stabilization of device service life due to temperature fluctuation and to limit the number of fluctuations of unpleasant noise caused by fluctuation of a fan rotational frequency in a cooling system using an adsorption type refrigerating machine. SOLUTION: The temperature control system in the adsorption type refrigerating machine is provided with temperature control means 11a, 12a-12f, and 13 for carrying out control of suppressing a temperature fluctuation width of a heating medium within a certain range during a change-over between adsorption and desorption processes of a refrigerant in the adsorption type refrigerating machine. The rotational frequency of a fan for cooling an outdoor heat exchanger is controlled in response to inlet and outlet temperatures (measured by a fan 11a) of outdoor air inputted and outputted in the outdoor heat exchanger, in response to temperatures (12b and 12c by temperature sensors) of the heating medium inputted and outputted in the outdoor heat exchanger, or in response to at least one inputted and outputted heating medium temperature 12b, 12c, 12d, or 12e of a plurality of indoor heat exchangers, or a rotational frequency of a pump is controlled on the basis of an outlet temperature 12f of the heating medium from a first heating unit 2. By this, the temperature fluctuation width of the heating medium is suppressed within a certain range. COPYRIGHT: (C)2004,JPO&NCIPI
