An adsorption module has heat medium pipes through which a fluid flows, a porous heat transferring member, and adsorbent. The porous heat transferring member is a sintered body formed by sintering a metallic material that is in a form of one of powders, particles and fibers, and has pores for allowing an adsorbed medium to pass through. The porous heat transferring member is disposed on peripheries of the heat medium pipes and bonded to outer surfaces of the heat medium pipes by sintering. The adsorbent is disposed in the pores. The porous heat transferring member further has an adsorbed medium passage for allowing the adsorbed medium to pass through. The adsorbed medium passage is located between the heat medium pipes, and extends straight and parallel to axes of the heat medium pipes.

According to the invention, the temperature and flow rate of cooling water for removing the heat of absorption are controlled artificially according to the cold output of load water by utilizing heated cooling water after the removal of the heat of absorption or heat source water, etc. According to the invention, a coolant tank and a load heat exchanger unit are provided as separate units. A load carrier is provided for cooling the load while partly evaporating the coolant through heat exchange between liquid coolant supplied from the coolant supplied from the coolant tank through a pump and the load. Mixture fluid of liquid coolant and vapor coolant after the heat exchange in the load cooler are returned to the coolant tank for separation of gas and liquid. Because the coolant tank and the load cooler are provided separately, the heat exchange with the load is performed by utilizing the latent heat of evaporation of coolant independently of possible temperature variations in the coolant tank. It is thus possible to obtain load heat at a constant temperature.

A heat exchanger having an adsorbing core is advantageously applied to a refrigerating system mounted on an automotive vehicle. The adsorbing core absorbs heat from coolant and gives heat to the coolant thereby to perform heat-exchanging operation. The adsorbing core is composed of a heat exchanging member such as tubes or fins of the heat exchanger and a attracting layer connected to the surface of the heat exchanging member. A seed crystal retaining layer is firmly connected to the surface of the heat exchanging member, and the attractant crystals forming the attractant layer are grown on the seed crystals by a hydrothermal crystal growth method. Since the attracting layer is uniformly formed and firmly connected to the surface of the heat exchanging member, heat is quickly transferred between the attractant layer and the heat exchanging member.
