Technical and Economic Evaluation of Ice Thermal Energy Storage Performance in Different Climates for Official Buildings in Iran

Authors

Abstract

In this paper the performance of Ice Thermal Energy Storage (ITES) systems has been modeled for an official building. In the present study, the ice storage tank is considered to be charged for 8-16 hours out of peak- time, and the tank content is supposed to be consumed during peak consumption time. In this paper, the internal Ice-On-Coil technology has been investigated. A four-floor official building of about 3106 m2 area is considered. The effects of different climates in various cities of Iran on energy consumption for charging and discharging storage tanks are considered. A comprehensive comparison between power consumption chiller without ITES system and power consumption chiller with ITES system in various coefficient of performance (COP) of chiller has been studied. It has been found from the obtained results that Bandar Abbas, among the considered cities, has higher energy consumption during peak hours of National Power Grid (NPG), so ITES system has a greater impact on the NPG peak saving in tropical regions. At the same time, COP Chillers with and without ITES systems, by using ITES system, had a reduction of about 26 percent in electricity consumption per day.
