摘要
在阐述闭式冷却塔供冷的工作原理及毛细管空调系统特点的基础上,比较分析了不同闭式冷却塔供冷模式,确定了夏季以闭式冷却塔直接为毛细管平面空调系统提供冷源是一种节能的有效模式。随后,根据标准年气象资料,对乌鲁木齐地区室外空气湿球温度进行了分析,结果表明,该地区全年有8376h湿球温度不超过16℃,可以利用冷却塔循环冷却水直接供冷,且夏季三个月当中有1930h可以实现免费供冷,这对在我国西部地区推广毛细管平面辐射空调系统具有积极意义。
Based on elaborating the cooling principle of closed cooling tower and the characteristics of capillary tube air-conditioning system,compared different cooling modes of closed cooling tower,confirmed that it＇s an effective energy-saving mode when closed cooling tower directly supplying cold source for capillary tube air-conditioning system.According to standard meteorological data,analyze the air wet-bulb temperature of Urumqi,the result shows that there are 8376 hours of wet-bulb temperature not exceed 16℃ throughout the area all year round,that means the cooling water could be directly sent to capillary tube air-conditioning for cooling,also there are 1930 hours that free cooling could be used among three months of summer,it＇s positive for promoting capillary tube air-conditioning system in West China.
