摘　　要：基于除湿换热器技术的新型回热型全新风除湿系统（以下简称：回热型除湿系统）通过引入回热装置,一方面可以改善系统的除湿处理能力,在降低处理空气出口温度的同时,提高系统的全热制冷量;另一方面,大幅提高了系统的热力学COP,与不带回热装置的除湿系统相比,在同等工况条件下回热型除湿系统的热力学COP可以由0.5-0.6大幅提高至1.2左右。A novel fresh air desiccant system using silica gel coated heat exchanger is fabricated and introduced with heat recovery in this paper.It can be proved that heat recovery device can provide significant benefits to the desiccant performance of the system.The output total cooling capacity increases because of a lower supply air temperature.In addition,the thermal COP of the novel system can be improved to 1.2,comparing with the traditional system without heat recovery.
