一种新型热湿独立控制系统冬季工况下的实验研究

Performance Analysis of a Novel Temperature and Humidity Independent Control System under Winter Conditions

热湿独立控制系统对显热和潜热负荷分开独立处理和控制,通常比传统热泵空调系统高效节能。在冬季工况下对一种新型的湿负荷处理系统(DESICA)以及其与VRV组合构成的热湿独立控制系统进行了实验测试,并将实验结果与传统全热交换器(HRV)和VRV构成的复合系统进行比较研究。研究结果表明:与传统HRV&VRV复合系统相比,DESICA&VRV复合系统能提供更舒适的室内环境(室温21℃左右,相对湿度50%左右);同时,DESICA&VRV系统的能耗降低9%。

Temperature and humidity independent control systems handle sensible load and latent load separately. They are usually more efficient and consume less energy than traditional air conditioning systems. In this paper, a novel humidity control system （ DESICA）, and the temperature and humidity independent control system constituted of DESICA and VRV （variable refrigerant volume air conditioning system）, are studied through field experiment under winter conditions. The performance was compared with heat recovery ventilator （HRV） and VRV system. The results show that DESICA＆VRV system provides more indoor thermal comfort （21℃, 50% ） and consumes 9% less energy than HRV＆VRV system.
