循环风量对新型家用纯净水机制冷系统及制水性能的影响
|
摘要
提出一种利用蒸气压缩制冷和空气加湿除湿原理相结合的家用纯净水生产系统,基于所搭建的性能测试台,实验研究了系统运行工况参数、制冷量、系统功耗、COP以及单位时间制水量和单位能耗制水量等性能参数随循环风量的变化规律。结果表明:随着循环风量的增大,系统制冷量、功耗及单位时间制水量均呈现上升趋势,COP则存在一个峰值;在实验工况下系统最大制水量达668 g/h,同时该系统存在一个最佳的循环风量为110.2 m~3/h,使系统单位能耗制水量达最大,为2067 g/(kW·h)。利用该系统所制取水的卫生指标(TDS <3 mg/L)和日产水量(> 12 L/d)均可满足一般家庭饮用需求,具有广阔的应用前景。
In this paper, a novel household pure water production system was proposed and established by combining the principles of vapor compression refrigeration and air humidification-dehumidification. The effects ofthe circulating air quantity on some running and performance parameters were experimentally conducted. Theseparameters included operating conditions of the system, refrigerating capacity, power consumption, coefficient ofperformance(COP), and produced water quantity of unit time and unit energy consumption. The results showed thatwith the increase of circulating air quantity, system refrigerating capacity, power consumption and produced waterquantity of unit time tended to rise, the COP showed a downward trend after rising first, and the maximum waterproduction of the system under the conditions studied in this paper was 668 g/h. The system has an optimalcirculating air volume of 110.2 m~3/h, which maximizes the system.s energy consumption per unit, which is 2067 g/(kW·h). The hygienic indicators(i.e. TDS less than 3) and daily production(above 12 L/d) of the water in the system can meet the requirements of the general household drinking and the system has a wide application prospect.
