摘要

传统热泵空调采用能效极低的冷凝除湿，需要增强除湿能力，提高能效。本文基于表面涂覆吸附剂的除湿换热器，提出一种新型的一体式除湿热泵空调循环。通过建立实验测试台，测试此新型循环在典型夏季工况下的送风含湿量、除湿量、送风温度以及COP，并对关键运行参数的影响进行分析。研究结果表明:新型一体式除湿热泵空调循环除湿效果良好，除湿量约7.9 g/kg，且系统COP能达到5.2以上，新、回风温度的变化会影响送风温度和COP，新、回风含湿量的变化会影响送风温度、送风含湿量、除湿量及COP。

Abstract

A normal heat pump air conditioner needs condensation dehumidification

leading to low energy efficiency. To improve the energy efficiency

a novel integrated dehumidification heat pump air-condition cycle

based on a desiccant-coated heat exchanger

is presented in this paper. Through the establishment of experiment table

the performance under summer condition of the novel cycle is tested and the influence of key operational parameters are analyzed. The results show that the novel integrated dehumidification heat pump air-condition cycle has good performance: the dehumidification quantity can reach 7.9 g/kg

and the coefficient of performance（COP）of the system can reach 5.2. The change in the temperature of fresh air and return air has influence on the temperature of supply air and COP. The change in humidity of the fresh air and return air has also influence on the temperature and humidity of the supply air

the dehumidification quantity

and COP.
