地铁车站冷水机组冷却供回水温度对空调能效的影响分析
Analysis of impact of cooling supply and return water temperature of subway station chiller units on air conditioning energy efficiency
摘要
Abstract
Based on the configuration of the conventional standard subway station air conditioning water system,the energy efficiency performance of screw chillers,centrifugal chillers,and magnetic levitation centrifugal chillers in the air conditioning room was compared and analyzed,and the influence of different cooling water supply and return temperatures on the energy efficiency of the air conditioning room was calculated and analyzed.The results show that when the cooling water supply and return water temperature is reduced to 35.5/30.5℃,the energy efficiency coefficient of the refrigeration room is increased by about 5%,which provides a reference for the relevant designers in the system configuration and parameter selection.关键词
