复合辐射空调系统供冷季地区适用性分析

Study on the regional applicability of composite radiant air conditioning system in cooling season

提出一种在毛细管辐射和独立新风的基础上增加风机盘管系统的复合毛细管辐射空调系统。采用EnergPlus软件从热舒适性和能耗两方面探究了该系统在不同气候区域的3座典型代表城市的适用性。结果表明3座城市在夏季典型设计日的热舒适性均能基本满足人体热舒适要求,其中广州市在整个供冷季的热舒适性优于上海市和北京市。广州、上海和北京市供冷季日均总能耗分别为33.4 kWh、30.6 kWh和27.2 kWh,相比于VRV空调系统的节能率分别为31.3%、32.7%和37.0%。

This paper proposed a composite capillary radiant air conditioning system that added a fan-coil system to a capillary radiation system with independent fresh air system.EnergPlus software was used to investigate the applicability of the composite system in three representative cities in different climate regions from two aspects of both thermal comfort performance and energy consumption performance.Results showed that the thermal comfort performance of the composite system in three cities on the typical summer design day can basically meet the thermal comfort requirements of the human body.However,for the entire cooling season,the thermal comfort performance in Guangzhou was better than that in Shanghai and Beijing.The average daily total energy consumption of the composite system during the cooling season in Guangzhou,Shanghai and Beijing was 33.4 kWh,30.6 kWh,and 27.2 kWh,respectively.And the energy saving rate was 31.3%,32.7%,and 37%,respectively,compared with VRV air conditioning systems.
