Performance of radiant cooling system integrated with ice storage

Abstract

The purpose of this study is designing a hybrid system which is a combination of radiant cooling and low temperature air conditioning integrated with ice storage system. Also this evaluates the performance of the system. We compared energy amount with annual operating costs of conventional air conditioning system and this radiant air conditioning system.

Analysis of energy and carbon dioxide emission caused by power consumption

“…In general, smaller temperature difference between the ice water influent and effluent indicates less power consumption so that the VV system consumes less energy than the CV system. Similar observations have been reported in literature [42][43][44][45]. Results from this study show that the air volume using the VV system has been significantly enhanced.…”

Experimental Study for Using Ice in Air Conditioning to Reduce Peak Loads

“…It providing an enhanced coefficient of performance technology through sub-cooling of high temperature condensate refrigerant, it also balances the cooling load to permit the outdoor unit operating at full load condition. Performance of radiant cooling system integrated with ice storage [15]. It was found of calculations that ice storage system makes the effect of dehumidification higher, and prevent from the occurrence of condensation.…”
