“…Chen et al [95] reported a theoretical and experimental work dealing with a solarassisted hybrid air-cooled adiabatic absorption and vapor compression air conditioning system that consisted of two coupled modes: the sub-cooling mode and the cascade mode. The experimental results of the cascade mode show that the COP of the VCC significantly increases with the growth of the hot water temperature, with a maximum increment of 162.0% when the hot water inlet temperature is 90 • C. The simulation results show an increment of 63.9-166.7% in the electric COP of the system in the cascade mode, which is similar to the experimental findings.…”

The aim of this study is to assess the state-of-the-art situation of mechanical compressors with thermal compressor systems in combined cooling systems and their ability to provide the required cooling effects with lower energy consumption than traditional cooling systems. The integrated systems have various advantages such as a broad temperature range, low energy consumption, and more flexibility in operating conditions. A comprehensive review of thermal‒mechanical combined cooling systems is presented in terms of its principles, applications, different configurations, and various heat source systems. Two types of thermal compressor systems are included in this study. The first one is the absorption system that uses a liquid‒vapor working pair in its thermodynamic cycle. Additionally, the second type is the adsorption system that utilizes a solid‒vapor working pair in its thermodynamic cycle. It is concluded that continuing technological innovations are vital for sustainable cooling. Technological developments can lead to cooling that is both inexpensive and energy-efficient.

“…Kashish Kumar and Alok Singh [13] suggest a coalescence of a liquid desiccant air-conditioning system with a VCR machine as a good alternative, in hot and humid areas. Using an absorption system and vapor compression refrigeration system with subcooling and a cascade mode for downsizing, Erjian Chen et al [14] suggested a solarpowered hybrid system with air cooling in their work.…”

In high temperature and high humidity zones, evaporative cooling is ineffective and vapour compression systems are less energy efficient. Therefore, an alternative system is highly desirable which is effective, energy efficient and enables the use of cheap and sustainable energy sources. Indirect evaporative cooling helps in retaining humidity level of air, but is less effective in attaining lower air temperatures. To mitigate this challenge, M-cycle indirect evaporative cooling system helps in achieving sub-wet bulb temperatures. In this work, performance of a novel modified indirect evaporative M-cycle cooling system assisted by 40% aqueous Li-Cl liquid desiccant is experimentally investigated against various parameters. The cooling system used in this study is a single unit system which can perform indirect evaporative cooling, liquid desiccant dehumidification and internal cooling to the liquid desiccant. With an air velocity of 1 m/s at the inlet, the introduction of openings in between inlet and exit of the cooling system has shown a maximum improvement of 19.2% in its dew point effectiveness, with unaffected dehumidification effectiveness. Furthermore, it is observed that the dew point effectiveness is decreased with the increasing distance of openings from the inlet. The investigated cooling and dehumidification system is useful as a pre-air-conditioner to conventional air-conditioning systems and also as a stand-alone air-conditioning system.
