摘要
为了解决一次回风式空调系统夏季制冷时耗电量大、能源浪费严重的问题及减小城市的局部“热岛效应”，本文提出了采用双冷凝器的冷凝热回收再热空气系统，并采用该系统对南京地区某演讲厅的空调系统进行了实例设计，设计结果表明：该系统相对一次回风式系统而言制取lkW冷量可省电0．154kW。另外，在满足送风温差要求的条件下，可通过改变再热风量的方式使该系统在88．0％·105．7％的供冷范围里实现室内恒温控制。
In order to solve the problem of large power consumption and serious waste of energy when air conditioning system with primary retum air is used for refrigeration in summer and reduce urban local heat island effect, air conditioning system with two condensers by condensing heat recovery for reheating air is put forward in this paper and is conducted for the design of air conditioning system of a lecture hall in Nanjing area. The design results show that this system can reduce power consumption by 10.8 kW per kW refrigerating capacity than air conditioning system with primary retum air. Furthermore, this system can realize the indoor air constant temperature control in the cooling range of 88.0%-105.7% by changing reheat air volume in the condition of meeting the requirement of the supply air temperature difference.
