摘要
本文介绍了一种冰蓄冷空调系统,采用永磁同步变频离心式冰蓄冷双工况制冷机组与基载制冷机组进行蓄冰、供冷。该系统具有配电功率低、日间制冷机组制冷效率高、系统控制简单等特点。结合该商业广场的冰蓄冷设计,对蓄冰方式的设计和运行策略进行了分析,并与常规中央空调系统在投资和运行费用方面进行比较分析。结果表明冰蓄冷系统的经济性好于常规中央空调系统。
In the present study, a new ice storage system was introduced, and it uses permanent magnet synchronous inverter centrifugal dual duty refrigerating unit combined with refrigerating unit of based load. This system has the advantages of low power, high COP in daytime and simple control. According to the ice thermal storage design of a financial center, the icestorage method and the operation strategy of this system were also introduced, meanwhile the investment and operating cost differences between this system and conventional ice storage system were analyzed. The results indicated that the economy of this ice storage system is superior to that of the conventional central air - conditioning system.
