摘　　要：应用蒸汽驱动的五个由氨-复合吸附剂作制冷工质构成吸附床的制冷空调测试平台,分析循环冷却水进口温度、冷剂的循环量、蒸发温度、加热蒸汽的温度与体积流率变化影响系统供冷量的特点。结果表明,降低循环冷却水进口温度、合理地调控制冷剂流量和提供合适温度和体积流率的蒸汽可提高系统的制冷量和系统运行的稳定性。系统采用电加热锅炉产生蒸汽驱动时,制冷系数(COP)约为0.16,而采用船舶废气锅炉产生蒸汽驱动的COP将可达到1.02。Applied of the refrigeration performance of a steam powered ammonia adsorption refrigeration unit, which consists of five adsorbers packed with composite adsorbent, the analysis is＇ carried out by varying the inlet temperature, the flow rate of the refrigerant, evaporation temperature as well as the temperature and the volume flow rate of the heating medium. The results show that lowering the inlet temperature of the cooling water, reasonably setting the flow rate of the refrigerant and the steam for heating the adsorbent bed are crucial to stabilizing the refrigerating capacity. The coefficient of the performance （COP） of the unit is about 0.16 with inclusion of the electrical power consumption of the boiler. However, the COP would reach 1.02 on board ship if the steam from the exhaust gas boiler is used.
