Abstract: This paper thoroughly reviews the integration of absorption, adsorption and desiccant cooling technologies into vapor compression cooling/refrigeration systems. Different configurations of hybrid absorption-compression cooling systems have been collectively listed and studied based on energetic, exergetic, economic and environmental analysis. Several reviewed studies revealed that such systems could diminish the electricity consumption by 45–88% in comparison with conventional compression systems. Besides, various arrangements of hybrid adsorption-compression cooling systems have been intensively investigated using cascade, partially integrated and fully integrated systems. These layouts of integrated adsorption-compression cooling systems focus on escalating the performance of vapor compression cooling systems by dwindling their condensation temperatures. Surveys showed that using adsorption cooling systems with oversized capacity could result in increasing the performance until approaching freezing limits, while downscaled adsorption cooling systems could worsen the system performance as a result of increasing the intermediate condensation temperature. The amalgamation of vapor compression systems with both solid and liquid desiccant cooling cycles has also been reported and compared with different regeneration schemes; for instance, electric energy, solar energy and heat rejected from the assisted vapor compression cooling systems. Considerable studies confirmed that using multi-stage solid desiccant cooling systems compared with single-stage solid desiccant cooling systems can be operated at lower regeneration temperatures. Also by introducing integrated liquid desiccant-vapor compression systems, cooling can be attained with a dehumidification process that cools the supply air lesser than its dew point with an energy provision of 30–80%. This work is beneficial for researchers involved in the field of multi-integrated cooling systems.
