以广州为例分析了热湿地区冷却顶板空调系统新风冷负荷的特点,显示夏季空调期新风湿负荷占新风总负荷的90%以上。提出了利用太阳能液体除湿处理冷却顶板空调系统新风湿负荷的方案,并将其与常规的冷却除湿方案进行了比较。结果显示,冷却顶板空调系统新风湿负荷的太阳能液体除湿方式比冷却除湿方式节能40%以上,静态投资回收年限为2.2年,认为冷却顶板空调系统新风湿负荷的太阳能液体除湿方式要优于冷却除湿方式。
Taking Guangzhou as an example, the characteristics of the fresh air cooling load of cooling roof air conditioning system in hot and humid areas were analyzed. The results show that the fresh air conditioning load accounts for more than 90% of the total fresh air load in summer. The scheme of using the solar liquid dehumidification to cool the air conditioning system of the roof cooling system is proposed and compared with the conventional cooling dehumidification scheme. The results show that the dehumidifying method of solar liquid with the new rheological load of cooling air conditioning system is more than 40% energy saving and the static investment recovery period is 2.2 years. It is considered that the dehumidifying method of solar liquid with the new rheological load of cooling roof air conditioning system is better than the cooling dehumidification the way.
