| 摘 要： | 设计了一套闭式循环太阳能吸附式制冷系统,该系统主要包括150m^2的真空管太阳能集热器、2台额定容量为15kW的吸附式制冷机组、1台冷却塔、风机盘管以及循环水泵.实验表明：由于水容量较小,系统的运行过程呈现出波动特性;由于进入太阳能集热器阵列的水直接来自吸附式制冷机组,太阳能集热器阵列的进出口水温周期性地振荡;此外,吸附式制冷机组的进口水温波动明显.然而,系统的制冷性能达到令人满意的效果.与开式循环系统相比,闭式循环系统由于减少了循环水泵的数量具有高电力COP的优势.

| Abstract: | A closed-cycle solar-powered adsorption cooling system is designed.The system is mainly composed of the evacuated tubular solar collectors with an area of 150 m^2,two adsorption chillers with a rated cooling capacity of 15 kW,a cooling tower,fan coils and circulating pumps.The experiments were carried out to study the operating characteristics and the performance of the system.It is found that the operation of the system presents wave characteristics because of low water capacity.The water temperatures of the inlet and the outlet of the solar collector array cyclically swing since the water entering the solar collector array comes directly from the adsorption chillers.Besides,the inlet water temperature of the adsorption chillers varies distinctly.However,the cooling effect of the system is satisfactory.Compared with an open-cycle system,the closed-cycle system has the advantage of a high electric COP（coefficient of performance）because of the reduced use of circulating pumps. |
