Study on the Minitype Solar Absorption Refrigerating Machine with the Air Bulb Pump

] Each state point parameter of the refrigerating cycle in the design parameter of the minitype solar absorption refrigerating machine with the air bulb pump is determined. The heating load of the generator, condenser, evaporator, absorber and solution heat exchanger and the circulating medium flow amount of the hot water, cold water, cooling air, dilute solution are calculated. The heat-transfer area demand of the heat-exchange equipments, such as generator, condenser, evaporator, absorber and solution heat exchanger, are computed. According to the calculated heat-transfer area, the heat-transfer pipe amounts of heat-exchange equipment are attained. The inner diameter sizes of heat water intake and outlet tubing, cooling water and cold water inlet tubing are determined. This provides a certain theoretic and practical basis for the minitype absorption refrigerating machine development.
