Review of solar assisted HVAC systems; Its performance analysis using CO2 as a refrigerant.

The main aim of this study is to review researches that have been carried out on solar assisted HVAC systems. The objective is to design a basic solar assisted air conditioning system that uses CO2 as a refrigerant. The performance analysis of the system is done with EES and Copeland Scroll software. Research about the solar-assisted HVAC system has advanced as some studies reveal solar-assisted system that can operate for 24 h. In this kind of system, the storage is important and takes a sizeable amount of space and cost in the design. Also, LiBr is one of the most commonly used efficient absorber in absorption refrigeration for HVAC. The details of all the findings and the performance of the system designed is given in the paper.
