This paper presents the recent studies on hybrid air conditioning systems. Additionally, the fundamental vapour compression system and components involved within the solar air conditioning system are discussed. The introduction of lowtemperature storage is an interactive solution and improve economically which portrays different modes of operating strategies. Yet, only a few studies have examined on the optimal operating strategy of the hybrid system. Finally, the findings of this review will help suggest optimization of solar absorption and vapour compression-based hybrid air-con systems for
future work while considering both economic and environmental factors. A comprehensive review has been conducted on the previous research’s that were published, which includes studies, specifications, and experimentally measured values of air conditioning systems in various tropical or subtropical climates in all countries of the world. The air conditioning regulators were divided into two main parts, the traditional cycle and the hybrid cycle, and a study of the working mechanism of each of the two systems, with illustrations for each cycle. A brief overview of solar collectors with different specifications and values, available spaces, and amounts of energy produced from emitted solar radiation was also discussed. Solar energy is also categorized into two main categories: solar thermal collectors, solar photovoltaic panels. The focus of the research has been on the past ten years. Different results were obtained in terms of economic and energy savings, with an average of 25% to 60% of the total energy consumed in the refrigeration cycle annually. Improvement in COP (Coefficient of Performance) is also observed at rates ranging from 10% to 20% at peak temperatures during the summer. Researchers ecommended the use of vacuum tube types of solar collectors because they are more efficient, effective, and serviceable in volatile conditions, as well as occupying less space than other types of solar collectors. In terms of performance, the COP was recorded at a rate of 5.6 to 4.6, while the COP for the absorbance system was very low, with a rate of 1.2 to 2.
