Influence of circulating air quantity on cooling system and water producing performance of new household pure water machine

WANG Li;WU Weidong;HU Kun;School of Energy and Power Engineering, University of Shanghai for Science and Technology;  
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.
