摘要
高铁客运站空调系统具有冷负荷峰值大、负荷变化大、能耗高等特点,是高铁客运站建筑节能的工作重点.通过调研郑州东站空调系统现状,在冷量损失、漏风/漏接、温度分层、辐射热量、能效、智能管理手段方面分析当前空调系统存在问题,从节流、开源、节能管控改造3个维度提出控制策略,为降低能源消耗提供决策依据,也为其他客运站空调系统优化管理提供重要参考.
Abstract
The refrigeration system of high-speed railway passenger stations has the characteristics of high peak cooling load,large load variation,and high energy consumption,and is a key focus of energy-saving work for high-speed railway passenger station buildings.By investigating the current status of the air conditioning system at Zhengzhou East Station,this study analyzes the existing problems in terms of cooling capacity loss,air leakage/connection,temperature stratification,radiant heat,energy efficiency,and intelligent management methods.Control strategies are proposed from three dimensions:throttling,open source,and energy-saving control transformation.These strategies provide decision-making basis for reducing energy consumption and important references for optimizing the management of air conditioning systems at other passenger stations.
