单冷源与双冷源的毛细辐射空调系统的能耗分析

Energy consumption analysis of capillary radiation air conditioning system with single and double cooling sources

随着经济的迅速发展,能源供给日趋紧张,在城市的建筑能耗中,空调能耗占整体能耗近一半,因此,研究降低建筑能耗的经济合理措施极为必要^([1])。文章简要介绍了毛细管辐射空调中单冷源系统和双冷源系统的特性,使用EnergyPlus软件,模拟单冷源系统与双冷源系统应用于毛细辐射空调末端的运行工况,利用SketchUp和EnergyPlus进行建模与能耗分析,最终得出采用毛细管辐射末端时,双温冷源温湿分控系统相比于单冷源系统节能19.3%,对实际工程中空调系统的设计具有一定的参考意义。

With the rapid development of the economy,energy supply is becoming increasingly tight.Among the building energy consumption in cities,air-conditioning energy consumption accounts for nearly half of the overall energy consumption.Therefore,it is extremely necessary to study economic and reasonable measures to reduce building energy consumption.Radiant air-conditioning has been invented since its invention,It is gradually popularized with its high comfort and energy saving.This article will briefly introduce the characteristics of the single cold source system and the dual cold source system in the capillary radiant air conditioner,using EnergyPlus software to simulate the operating conditions of the single cold source system and the dual cold source system applied to the capillary radiant air conditioner terminal,using SketchUp and EnergyPlus to perform Modeling and energy consumption analysis finally concluded that when using capillary radiation terminal,the dual-temperature cold source temperature and humidity sub-control system is more energy-efficient than the single cold source system,which has certain reference significance for the design of air-conditioning systems in actual projects.
