摘要/Abstract

摘要：

提出一种由固体除湿热泵(DESICA)和变频多联机(VRV)组成的新型热湿独立控制空调系统(JDVS),为验证其实际舒适和节能性能进行了实验研究。DESICA是一台新型固体除湿热泵,其原理是用涂覆固体除湿材料的除湿换热器替代传统热泵中的蒸发器和冷凝器,并通过四通阀实现系统的连续运行。在JDVS中,DESICA负责处理潜热负荷和部分显热负荷,剩余的显热负荷由VRV处理。因此,对比目前普遍采用的全热交换器(HRV)和VRV所组成的传统热湿独立控制空调系统(JHVS),在上海冬夏季工况下进行实验研究。实验结果显示,新型JDVS系统相比JHVS系统,在满足设定温度的同时,能将室内相对湿度维持在50%左右。同时,在夏季和冬季工况下,JDVS系统比传统JHVS系统分别节能17.2%和9.3%。因而,新型JDVS兼具节能和舒适特点,拥有广阔应用空间。

Abstract:

A novel temperature and humidity independent control system (THIC) is proposed in this paper, and then experimental investigation of this system is conducted to evaluate its system performance. The THIC system is constituted of a novel solid desiccant heat pump (DESICA) to deal with the latent load and a variable refrigerant flow air conditioning system (VRV) to handle the sensible load. In order to verify the actual performance of this novel joint DESICA and VRV system (JDVS), operation performance of this system is experimentally tested and compared with commonly adopted joint heat recovery ventilator (HRV) and VRV system (JHVS). These two hybrid systems are installed in an office room and operated on adjacent days during typical winter (Dec, 2012 to January, 2013) and summer (July, 2013 to August, 2013) season in Shanghai. From the experiment results, it is found that the proposed JDVS can provide better indoor thermal comfort while consuming less energy in both winter and summer season, compared with the traditional JHVS.
