摘要

在我国南方地区，日照情况较好，光伏空调具有较好的气候适用性。目前针对光伏空调的研究主要基于小型光伏空调系统。对位于珠海的光伏直驱变频空调（离心式水冷冷水机组）系统进行实验和分析，引入并网太阳能保证率的分析指标，并评价了冷水机组的部分负荷运行情况、性能系数（COP）、热力完善度。结果表明，在某一典型天工况下光伏空调的太阳能保证率为63.20%，平均COP为6.64，热力完善度为65.94%。光伏直驱离心式水冷冷水机组运行可靠且有较好的节能特性和工作性能。

Abstract

In southern China

photovoltaic air-conditioner(PVAC)has a great climate suitability since the energy consumption of air-conditioners is high while the sunshine is abundant there in summer.At present

researches on PVAC are mainly based on small-scale system.Study on commercial and large-scale PVAC is still lacking.The paper introduces the performance experiment and analysis of a photovoltaic direct-driven centrifugal water-cooled chiller in Zhuhai.Analysis index like grid-connected solar fraction is used.The part-load working condition

coefficient of performance and thermodynamical perfectness of the water chillers are also studied.The result shows that

in a typical day

the values of solar fraction

COP and thermodynamical perfectness of the system are 63.20%

6.64 and 65.94% respectively.The photovoltaic direct-driven centrifugal water-cooled chiller can work reliably and has a great energy-saving performance.
