光伏直驱离心式水冷冷水机组性能测试与分析
Performance experiment and analysis of photovoltaic direct-driven centrifugal water-cooled water chiller
摘要
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.关键词
