摘要
我国夏热冬冷地区每年用于夏季空调的能耗很大,而该地区夏季降雨较多.将雨水回收均匀淋洒于空调冷凝器上,通过理论计算和实验研究相结合的方法,研究了喷淋水对改善冷凝器散热性能的影响.结果表明:(1)在相同的流量下,与单排孔相比,采用双排孔的滴水方式节能率更高.流量为19.17ml/s时,当室外干球温度35℃,相对湿度65％时,双排孔喷淋节能率可达15％以上;(2)在相同的滴水方式下,流量越大,节能率越高;(3)室外空气的相对湿度越低,节能效果越明显.利用雨水前后空调系统COP可提升近10％.
Abstract
In hot summers and cold wintersregions,the energy consumption for summer air conditioning is relatively high,and these regions experience higher levels of rainfall.This study investigates the effect ofspraying rainwateruniformly on condenser to improve the air conditioner heat dissipation performance.A combination of theoretical calculations and experimental research was employed.The results indicate that:(1)Compared to a single-row hole design,the drip method with a double-row hole design achieves higher energy efficiency with the same flow rate.At a flow rate of 19.17 ml/s,when the outdoor dry bulb temperature is 35℃ and the relative humidity is 65％,the energy-saving rate of the double-row hole spray can reach above 15％;(2)Under the same drip method,increasing the flow rate leads to higher energy savings;(3)The lower the relative humidity of the outdoor air,the more significant the energy-saving effect.The COP(Coefficient of Performance)of the air conditioning system can be improved by nearly 10％by utilizing rainwater.
