夏季热湿地区新风冷负荷特点及新风湿负荷的处理

The Character of Fresh Air Cooing Load in Summer of Hot - Humid Area and Handling of Fresh Air Moisture Load

以广州为例,分析了热湿地区空调建筑物新风负荷的特点,得出在整个夏季新风冷负荷中潜冷负荷占87.9%,由此可见用于夏季新风除湿的能耗远远超过用于新风降温的能耗。对常见的三种除湿方式用于夏季空调新风除湿方案进行了综合分析,认为液体干燥剂除湿系统最适合用于热湿地区夏季新风湿负荷的处理。

Taking Guangzhou for example, the character of fresh air cooling load of building using air - conditioning is analyzed. It is found that 87.9 percent of the whole summer fresh air load is latent heat load. Therefore the energy using for dehumidification is much more than that using for cooling. Three dehumidification methods using for handling fresh air are analyzed, and the liquid desiccant dehumidification method is found to be the most suitable one for hot- humid area。
