本文建立了一个由除湿、蒸发冷却和蒸汽压缩空调组成的复合空调系统。实验研究表明，与单独的蒸汽压缩系统相比，新的混合系统的制冷量和COP可以显着增加。假设系统出口温度和湿度恒定，在ARI条件下进行了三种不同情况下的干湿分析。其优点表现为压缩机耗电量低、系统COP高、冷凝空气流量小、换热器尺寸小等。混合系统性能上级传统系统的原因在于除湿制冷和蒸发冷却改变了进入换热器的空气的入口状态。此外，还分析了蒸发冷却和冷凝冷却的效果。(C)2001爱思唯尔科技有限公司版权所有。
A hybrid air conditioning system, which consists of sections of desiccant dehumidification, evaporative cooling and vapor compression air conditioning, has been established in this paper. Experimental investigation demonstrates that cooling production and COP of the new hybrid system can be increased significantly, if they are compared with those of vapor compression system (VCS) alone. Assuming that the outlet temperature and humidity of the system are constant, psychrometric analysis at ARI conditions has been conducted under three different cases. The benefits are represented by lower electricity consumption of the compressor, higher COP of the system, less flow rate of condensation air, and reduced size of VCS, etc. The reason that the hybrid system is superior in performance to conventional systems lies in that desiccant dehumidification and evaporative cooling changes the inlet states of the air entering into VCS. Furthermore, the effects of dehumidification and evaporative cooling are analyzed in the paper. (C) 2001 Elsevier Science Ltd. All rights reserved.
