<p>An air-cooled absorption type water cooling/heating apparatus has a cooling circulation system including an evaporator (7) in which a liquid refrigerant is evaporated so as to cool a heat exchanger leading to a cooling heat radiator, and a heating circulation system including a heat exchanger leading to a heating heat radiator and disposed in a separator (2) in which the solution which has been thinned as a result of absorption of the refrigerant is heated and fractionated into refrigerant vapor and thick solution. In the heating mode of operation, the circulation passage for the solution, which is controller by a control valve (14), is closed, and the circulation passage for the refrigerant, controlled by a control valve (15), is also closed. This arrangement enables a heat source (10), which is used for heating the refrigerant and the absorption solution in the cooling mode of operation, to be used also in the heating mode of operation, so that the construction of the apparatus as a whole is made compact.</p> |
