| 中文摘要: |
| 温度和新风量的大小在影响室内环境的舒适性方面起着重要的作用。为了改善室内空调环境，ASHRAB规定设计温度应该保持在30％-60％之间，且需要把原有的设计新风量增大2倍至4倍。显然，降低温度和增大新风会加大空调的冷负荷，传统的空调供冷系统在满足上述条件方面显示出了自身的一些缺点。吸温供冷系统把除温和冷却降温供冷解耦分开处理．不但能把空气温度处理到一个比较低的程度，而且在节能方面也显示出很大的潜力。对吸温供冷系统的几种空气处理方式进行了分析和比较，从而可根据不同的情况为吸温供冷系统的使用选择比较理想的空气处理方式，以达到节能目的。 |

| Humidity and fresh air play an important role in acquiring a comfortable indoor environment. In order to improve the indoor air-conditioning environment, ASHRAE specified that the design relative humidity should be remained between 30% ~ 60% and the amount of fresh air should increase up to 2 ~ 4 times of the original design value. Decreasing the humidity and increasing the amount of fresh air will obviously increase the cooling load of the air-conditioning system. However, conventional air-conditioning cooling systems are inadequate to come up to the new standard. In the desiccant cooling system, the processes of dehumidification and cooling are conducted separately. The air humidity can thus be decreased to a very low degree and the system shows great potential in saving energy. In this paper, air processing methods in the desiccant cooling system were analyzed and compared, the results of which are helpful to select reasonable air processing methods for the desiccant cooling system according to different conditions in order to save energy. |
