摘　　要：空调冷凝水回收具有很大的潜力,是解决水资源紧缺的有效途径之一。文章基于不同空调系统在焓湿图上的表示,确定了其冷凝水生成量的计算公式,分析了各空调系统的冷凝水生成量组成,并针对相同办公建筑,计算了夏季我国各省会和首府城市单位空调冷凝水的生产量。结果表明:夏热地区可产生的冷凝水量最大,其次是寒冷地区、严寒地区,但西部的寒冷地区和严寒地区无收集价值;相同室内设计温度时,室内相对湿度取值越小,空调冷凝水生成量越多,温度高、相对湿度大的室外环境有利于生成更多的冷凝水;实际运行过程中,空调冷凝水量并不是固定值,其会受到室外空气状态参数的影响。The condensate of air conditioning has great recovery potential,and it is an effective way to solve the shortage of water resources.Based on the enthalpy-humidity diagrams,the calculation formulas of the condensate water production of different air-conditioning systems are determined and analyzed.It is concluded that the total condensate water production of all air-conditioning systems is composed of indoor moisture load and fresh air moisture load.Through calculation and analysis of the condensate water for the given office building in each China's provincial capital,it can be known that the condensate water production is the largest in hot summer areas,then in cold areas,severe cold and temperate areas.There is no collection value in cold and severe cold areas in Western China.To the same indoor design temperature,the higher the value of indoor relative humidity,the higher the humidity content of indoor air,and the lower the difference between indoor and outdoor humidity content,and the lower the fresh air moisture load and the lower the condensate water.Higher outdoor air temperature and relative humidity would help to generate more condensate water.Air conditioning condensate water has great potential for recovery,and is an effective way to solve the shortage of water resources.
