蓄冰系统在不同功能建筑中的经济性分析

Economic Analysis of Ice Storage System in Buildings of Different Functions

冷源是空调系统的重要组成部分,其初投资及运行能耗在空调系统中所占比例相当可观。不同的建筑、采用何种冷源,在经济方面会有很大差异。通过蓄冰冷源与常规冷源在写字楼、酒店、综合楼等不同功能建筑中初投资与运行费用的综合经济比较,以回收年限做为衡量标准,给出了蓄冰冷源在不同功能建筑中的适用程度,便于在设计中对空调冷源的确定。由于不同地区的分时电价不同,不同时期的设备价格不同,计算结果也会不同,需采用这种分析方法重新校核。

The cold source is an important part of air conditioning system, its initial investment and operating cost take up a great proportion in air conditioning system. It will be large different in economic aspects of different buildings which adopt different cold source. The application of ice storage system in buildings of different functions is analyzed through the economic comparison of the ice storage system and conventional system in different buildings as office buildings, hotel and complex buildings, by payback period. This paper makes it easier to determine the cooling sources of air-conditioning. Because there is dif- ferent time-of-use tariff in different regions and different equipment prices in different periods, so the calculation results will be different, and it needs to adopt the analysis method to check again.
