摘要： PURPOSE:To prevent cavitation due to a decrease in a static pressure and circulation failure, generation of noise due to the cavitation by installing a pump mechanism to be driven by utilizing flow of solution from a high temperature regenerator to an absorber on a regenerated solution input route, and feeding the solution from the regenerator to the absorber. CONSTITUTION:At the time of heating, solution is heated to be boiled by a burner 11 in a high-temperature regenerator 1. Generated refrigerant vapor is pressure-reduced by a valve 31, then introduced to an evaporator 4, and condensed on an evaporating heat transfer tube 30 to heat heating warm water flowing in a tube. On the other hand, concentrated solution in the regenerator 1 is heat exchanged with solution from an absorber 5 by a high-temperature heat exchanger 10 to be cooled, and solution from a low-temperature regenerator 2 is sucked by a concentrated solution jet pump 8 which utilizes a loss head of a solution scattering unit 14 in the absorber 5 and a height head to the unit 14. The mixed solution in this case is heat exchanged with dilute solution from the absorber 5 in a low-temperature heat exchanger 9 to be further cooled, and then fed to the unit 14.

摘要： PURPOSE:To make compact the size of a cooled air absorber, minimize cooling air capacity, and reduce noise by installing a thermal material exchange device, shifting an absorption temperature level of an absorber to a higher temperature side, and increasing the differential temperature of heat exchange between the solution of the absorber and refrigerant air. CONSTITUTION:Enriched solution which returns from a high temperature generator 1 or a low temperature regenerator to an air-cooled absorber 5 is introduced into a regeneration chamber 15 of a thermal heat exchange device 14 so as to generate heat. On the other hand, the diluted solution generated in the air-cooled absorber 5 is introduced into an absorption chamber 16 of the thermal material exchange device 14 so as to absorb refrigerant vapor. As a result, the enriched solution which returns from the high temperature regenerator 1 or the low temperature regenerator to the air-cooled absorber 5, is further enriched since refrigerant vapor is generated at the thermal material exchange device 14 and the enriched solution is introduced into the air-cooled absorber 5. On the contrary, the diluted solution generated at the air-cooled absorber 5 absorbs refrigerant vapor at the thermal material exchange device 14 and turned into a diluted solution, which fed to the high temperature regenerator 1 or the low temperature regenerator 2. In this manner, only the air-cooled absorber is designed to operate at high temperature and high concentration, which makes it possible to increase differential heat exchange temperature against cooled-air.
