Abstract
Adsorption cooling is widely known as a simple thermal driven system that uses natural refrigerants in a sustainable way without contributing to the greenhouse effect. Nevertheless, the coefficient of performance and specific cooling power of the cycle are too low to be economically viable. Due to the rising energy demand and need for sustainable emissions, improvements in various aspects are being researched to make adsorption a competitive alternative by increasing the performance of the system. One major revolution in adsorption is the development of hybrid cycles. This work presents a review of the principal hybrid adsorption systems for domestic purposes and an application analysis was made. The systems involved in the research were all experimental prototype recent units that have been developed and tested, and they were chosen in order to cover the most used types of working-pairs including: Silica-gel-water, Zeolite-water, Activated carbon-methanol and Activated carbon-ammonia. A table was elaborated to summarize the review data and to enable clear comparison. Silica-gel-water and Activated carbon-methanol pairs presented the best results among the analysis made and seem to be the most promising for the applied use of adsorption technology.
