某办公项目冰蓄冷系统设计分析

Design and Analysis of Ice Storage System for an Office Project

以重庆某办公楼工程为例,针对空调系统冷源方案,结合当地能源政策及空调负荷特点,对常规制冷系统、冰蓄冷空调系统两个方案进行了系统经济技术分析和比较。与常规空调系统相比,冰蓄冷空调系统装机容量小,可节省配电设施费及运行费用,其中年运行费用节约29.6万元。但由于冰蓄冷系统增加了蓄冰设备,其初投资比常规空调系统增加约157万元。因而需要人为制定合理的运行策略,确保经济效益和社会效益。

Taking an office building project in Chongqing as an example,aiming at the cold source scheme of air conditioning system,combined with the local energy policy and the characteristics of air conditioning load,the system economic and technical analysis and comparison of conventional refrigeration system and ice storage air conditioning system were carried out.Compared with the conventional air conditioning system,the installed capacity of ice storage air conditioning system is small,which can save power distribution facilities and operation costs,the annual operating cost was saved by 296,000 yuan.However,because ice storage system adds ice storage equipment,its initial investment is larger than conventional air conditioning system,about 1,570,000 yuan Therefore,it is necessary to formulate reasonable operation strategies to ensure economic and social benefits.
