摘要

为了从整体的角度系统分析中央空调系统设置排风热回收对系统总能耗的影响

选取以风冷冷水机组为冷源的中央空调系统为研究对象

在保证空调区域热舒适性及室内空气品质满足要求的前提条件下

通过该系统从空调房间提取热量到最终排放到环境中4个连续环路的能流情况

建立了空调系统不设置和设置排风显热、全热回收装置的能流系统分析模型. 并以广州某商业服务中心中央空调系统为例

分别绘制了上述3种空调系统夏季设计工况下的能流图

直观地表现了3种空调系统能流、能耗之间的差异

为空调系统的优选及所选系统的节能降耗提供有用的信息.

Abstract

In order to systematically analyze the effect of setting exhaust heat recovery device on the overall energy consumption of the central air conditioning system

the central air conditioning system with air-cooled chiller as cold source is selected as study object. On the condition of meeting the requirement of the thermal comfort and indoor air quality

the energy flow mathematical models for this central air conditioning system with and without setting device of exhaust heat recovery are established through analyzing the energy flows of the four consecutive loops which extract energy from the conditioned spaces and reject it to the environment. Based on the HVAC design parameters of a commercial building in Guangzhou

the energy flow diagrams of this air conditioning system with and without exhaust heat recovery are drawn respectively

which can visualize the main differences of energy flow and energy consumption between different systems and provide useful messages for selection and energy saving potential of the system.
