A differential in refrigerant adsorption rates of adsorbent during an adsorption process and during a desorption process is enlarged, realizing improvement in refrigeration capacity, and together therewith, the number of circulation systems for coolant fluid is reduced and the number of pumps is made smaller. A heat exchanger of a first stage evaporator and a cooler for air conditioning use are connected in series, and coolant fluid cooled by this heat exchanger is supplied to the cooler for air conditioning use. Additionally, a heat exchanger of a second stage evaporator and a radiator are connected in series, coolant fluid cooled by the radiator is further cooled by the heat exchanger, and this coolant fluid is alternately supplied to heat exchanging passages of first first stage and second stage adsorption devices and to heat exchanging passages of second first stage and second stage adsorption devices.
