摘要
针对风冷型分体空调器在酷暑的高气温、强辐射等恶劣气候条件下制冷运行时,经常出现制冷能力不足、压缩机连续运行时间过长以及易出现过压、超温保护故障等现象,提出了采用湿帘加湿产生湿风来改善空调器冷凝换热效果的措施,并设计、试制了湿风冷却小型家用分体单冷空调器样机;利用环境试验室条件和焓差法测量制冷量方法,测试和分析研究了该样机在不同室外环境工况、相同室内环境工况下的综合能效比。结果表明:在标准工况下,湿风冷却空调器与同类型传统风冷空调器相比,其综合能效比可提高约15%,在高温工况下,湿风冷却措施不但可大大提高空调器在高温工况下的运行可靠性,而且其节能效果明显,为进一步研发节能型分体单冷空调器提供了一种有益的参考。
In this study, a method with humidifying-air flow from a wetted pad was presented to improve the heat exchange effect on a condenser, and a prototype was designed and fabricated. Using an environmental chamber and the enthalpy potential method to test the refrigerating capacity, the integrative energy efficiency ratio （EER） of the prototype was obtained and compared with that of a conventional split air conditioner with the same size under the different outdoor temperatures and the standard indoor temperature. The results show that the present method not only can improve the operation reliability and energy-saving under the high temperature condition but also can increase EER by 15% at least under the standard experimental condition.
