Abstract
An air-cooled absorption-type air-conditioning apparatus in which a simple design allows for heating and cooling and in addition in which freezing is prevented during the heating operation. A liquid coolant from the condenser is dripped onto the inner surface of the outer pipes in the evaporation-absorption chambers and removes the evaporation heat due to evaporation in low pressure. Therefore, the outer pipes are cooled. Overcooling of the outer pipes is prevented by a fan which directs the heat generated at the condenser to the outer pipes. The evaporated coolant is absorbed in the high-concentration liquid on the outer surface of the water pipes and the absorption heat generated by the high-concentration liquid heats the water flowing in the water pipes. A room unit performs the heating or cooling operation by using warm or chilled water circulating in the water pipes.
