摘要

为了从整个系统的角度分析以风冷热泵热水机组为热源的集中空调系统的运行能耗，借鉴工业领域能耗强度的概念，提出在满足热舒适度的前提下，为空调区域提供单位热量整个空调系统的能耗强度（Energy Intensity，EI）的概念.该概念将整个系统各环路的能耗全部包含了进来，又通过对EI的分解分析，建立了系统及其各环路能耗的

e-p

分析法，运用这种方法可将两种工况下系统各环路

和

的改变对系统能耗强度的影响进行定量分析.为了降低空调系统的能耗强度EI，有两种途径：一是减小系统各环路为输送单位流体流量所产生的耗功率

e，

二是减小为空调区域提供单位热量，各环路所输送的流量

Abstract

For analyzing from the point of the whole system the operational energy consumption of central air conditioning systems with air source heat pump unit

the global energy intensity index based on the thermal comfort of the conditioned space is put forward. It includes the energy consumption of all the system subloops. Through the decomposition of （Energy Intensity，EI）

the

e-p

analysis method for the whole system and its subloops is built

which can easily analyze the change of the specific consumption (

) and delivered fluid ratios (

) on EI. It is indispensable to decrease the specific consumption (

) and delivere fluid ratios(

) of each sub-loop in order to decrease

the EI of HVAC systems.
