Research and developments on solar assisted compression heat pump systems - A comprehensive review (Part-B: Applications)

The second part of this review presents a comprehensive review on applications of solar assisted compression heat pump systems and its associated research potentials. The reported investigations on solar assisted heat pumps are categorized into five major groups as follows: (a) drying, (b) room space heating; (c) agricultural green house space heating, (d) water heating and (e) desalination applications. Most of the reported investigations in open literature are reviewed. The study will then presents the major limitations of solar assisted compression heat pumps and further research tasks in various applications. This paper concludes that solar assisted compression heat pump system is the promising equipment used for heating applications. The information presented in the second part of the review is beneficial to the researchers, energy experts and decision makers in the field.
