摘要(Abstract):

对传统气泡泵进行分析,提出利用气压泵代替现有单压吸收式制冷机内气泡泵,并对气压泵工作原理与运行状态进行了分析。用饱和浓氨水作工质,分析了在一个循环内,气压泵的能耗与提升效率,得出气压泵效率约为传统气泡泵效率11.6倍的结论。
The idea of using pneumatic pump replace the bubble pump in single pressure absorption refrigeration was proposed.Besides,it analyzes the operating principle as well as operating condition of the pneumatic pumps. Energy consumption and efficiency promotion of the pneumatic pump is analyzed in a cycle when stronger saturated ammonia water is used as the working substance.Thus,a conclusion is drawn that the efficiency of the pneumatic pump is 11. 6 times higher than that of the traditional bubble pump.
