The use of phase change material (PCM) to improve the coefficient of perform - ance of a chiller for meeting domestic cooling in Wales

This paper investigates the possibility of integrating thermal energy storage to the hot side of LiBr/H 2 O 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 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 pro. 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/H 2 O absorption cooling system.
