中文摘要：
为了对一种新型吸收-压缩复合制冷循环的性能进行模拟,使用Visual Basic语言自行编制了一个程序。该程序模拟了发生温度、蒸发温度、冷凝温度、加热量、制冷量对系统性能的影响,并将其性能与传统蒸气压缩式制冷循环作了对比。模拟结果表明：当发生温度升高时,新循环的制冷系数先增大后减小;当蒸发温度升高或加热量增大时,新循环的制冷系数增大;当冷凝温度升高或制冷量增大时,新循环的制冷系数减小。在大部分假定工况下,新循环的制冷系数比传统蒸气压缩式循环的高10%以上。新循环的提出不仅能够大幅度减少空调电力负荷,还为太阳能等低品位能源的高效利用提供了可能。
英文摘要：
A program compiled by Visual Basic language was used to simulate a new combined absorption-compression refrigeration cycle for performance research,including the effect of generation temperature,evaporation temperature,condensation temperature,heat flux and refrigeration capacity on system performance which was compared with a conventional vapour compression refrigeration cycle.Simulation results show that when generation temperature increases,the coefficient of performance（COP） of new cycle increases first and then decreases.When evaporation temperature or heat flux increases,the COP of new cycle increases.When condensation temperature or refrigeration capacity increases,the COP of new cycle decreases.Under most simulation conditions,the COP of new cycle can be 10% higher than that of conventional vapour compression refrigeration cycle.The new cycle can not only reduce air conditioning load greatly,but also provide the possibility of efficient utilization of low grade energy such as solar energy.
