基于建筑能耗监管平台的VRV空调系统及集中式空调系统运行电耗分析

Analysis on the Operational Power Consumption of the VRV Air-conditioning System and Centralized Air-conditioning System based on Building Energy Monitoring and Management System

本文基于辽宁省3个建筑能耗监管平台对分别设有VRV及集中式空调系统的12栋办公建筑进行了建筑电耗分析。结果表明:VRV空调系统及集中式空调系统都存在很大的节能潜力;VRV空调系统随室内冷负荷变化的可调节性要好于集中式空调系统;最后指出影响两类空调系统节能运行的主要因素。

This paper analyzed the operational power consumption of 12 office buildings equipped with VRV and centralized air-conditioning systems in Liaoning Province according to the monitoring data derived from three building energy monitoring and management systems. Results show that both air-conditioning systems had great potential for energy saving,and the adjustability of VRV air-conditioning system was better than that of centralized air-conditioning system. Finally,the main effective factors of energy saving in the operation process of two airconditioning systems were pointed out.
