A review of chemical heat pump technology and applications

Chemical heat pumps (CHPs) provide high storage capacity and high heat of reaction as compared to sensible heat generated by absorption. Investigation of material properties and their operation have led to their heat pumps exploitation for commercial and industrial applications. Integration of solar thermal system to the CHPs would assist in expanding the utilization of CHPs and also for many applications in the tropical region. The research done in CHP regarding to status of technology, current applications and their future prospect has been reviewed, with special reference to their utilization with solar thermal energy for cold production and upgrading/storage of heat.
