Summary

Describes the integration of a chemical and vapour-compression heat pump for energy storage applications. The vapour-compression system is designed to operate using the UK cheap rate Economy 7 electricity tariff. States the system uses various refrigerant/absorbent pairs in the chemical storage unit and an ozone-friendly refrigerant, R134a, in the vapour-compression circuit. States the results indicate that the water-sodium sulfide pair provides a high energy storage density and is the most suitable for use in this system. Also describes the design features of a domestic-sized version of this heat pump system. Air in the conservatory of a house was used as a heat source for the heat pump.
