摘　　要：本文确定了设计计算参数下小型太阳能气泡泵吸收式制冷机制冷循环中各状态点参数,进行了发生器、冷凝器、蒸发器、吸收器、溶液热交换器的热负荷计算和加热热水、冷水、冷却水、稀溶液等循环介质的流量计算。进行了发生器、冷凝器、蒸发器、吸收器、溶液热交换器等换热设备所需的传热面积计算。根据求得的传热面积确定了各换热设备的传热管数,计算了热水进出口配管、冷却水进口配管、冷媒水进口配管的内径尺寸,为开发小型吸收式制冷机提供了一定的理论和实践基础。] 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.
