Abstract
This paper investigates the possibility of integrating thermal energy storage to the hot side of LiBr/H2O absorption cooling system to cover 100% of peak cooling load for a three bedroom house on the hottest summer day in Cardiff, Wales. A shell and tube experimental system was designed to conduct charging and discharging experiments using Erythritol (melting point 117.7°C) as a phase change material, considered to have the highest energy density in the temperature range investigated (90°C to 120°C). The results show that Erythritol meets the requirement of an appropriate temperature range of application for the hot side of an absorption air-conditioning system. Erythritol store of 100 litres would provide approximately 4.4 hours of cooling at peak load based on the optimum COP of 0.7 for LiBr/H2O absorption cooling system.
