摘　　要：本文从设计工况和运行调节工况两个方面,对采用环形热管换热器的空调方式与传统的露点送风空调方式的两种全空气系统进行了对比分析。分析结果表明,采用环形热管换热器的空调系统能在不增加空调系统需冷量的前提下,通过增加少量风机能耗来增大送风量和提高送风温度,提高室内热舒适,在运行调节时能通过利用从空气中回收的热量提供再热,减少或消除冷热抵消造成运行能耗。Comparison of the loop heat - pipe air conditioning system and the air conditioning system with apparatus dew point air- supply was investigated under the design and the operation condition in this article. The study showed that compared with the air conditioning system with apparatus dew point air- supply, the loop heat- pipe air conditioning system can improve the in- door thermal comfort by the increases of supply- air volume and supply- air temperature through consuming a small amount of fan energy, and decrease the operating energy consumption through reducing the energy offset of heating and cooling of air- handling processes with the heat recovered from outdoor air reheating air- supply without increasing coolin~ load.
