Abstract

This paper presents a comprehensive review on research and developments on solar assisted compression heat pump systems, mostly reported during the last two decades. The first part of this paper provides a detailed description of the past efforts on various system configurations, system modeling, enhancement of system performance, modifications in compression heat pump cycles and environment friendly refrigerant options for solar assisted compression heat pump systems. The economical and environmental impacts of solar assisted compression heat pump systems are also described. Further research needs in this important field of solar assisted compression heat pump are listed. The outcomes of this review confirm that, there is a lot of research scope for improving the performance of the system and reducing its initial cost to make it competitive in the global market. The information presented in this paper is shall be highly beneficial for the active researchers working presently on solar assisted compression heat pumps.
