硅胶-水吸附式冷风机组的设计及性能实验
|
摘要
吸附式冷风机组无须冷水回路和冷水泵,可满足小型化的应用需求。针对一种由2个吸附床,1个冷凝器和1个热管型的蒸发器的硅胶-水吸附式冷风机进行了实验研究,确定了机组的动态运行特性,探讨了热源温度、冷却水进口温度和冷风出口温度对系统性能的影响。实验结果表明,机组能够有效利用60～90℃范围内的低温热源,可提供0.84～2.29 kW的制冷量,系统的COP在0.26～0.43之间。
The adsorption air cooler does not require the cooling water circuit and the cooling water pump, so it can meet the needs of miniaturized applications. In this paper, a silica gel-water adsorption air cooler was experimentally studied, which consists of two adsorbers, one condenser and one heat pipe type evaporator. The dynamic operating characteristics of the cooler were obtained. This paper discusses the influence of heat source temperature, cooling water inlet temperature and cold air outlet temperature on system performance. The experimental results show that the cooler can be effectively driven by low-grade heat source at 60—90℃. The cooling capacity of 0.84—2.29 kW and the corresponding COPs of 0.26—0.43 were achieved.
