| Popis: | Chemisorption cooling is a type of technology that facilitates energy saving and produces less environment impact than that produced by vapor compression cooling systems. The advantages or disadvantages of these systems can be explored from mathematical models through which the impact of different working pairs as well as construction and operating parameters on these cooling systems can be described. In this sense, the impact of design variables on performance coefficient of a chemisorption refrigeration system that uses sodium bromide and ammonia as working pairs are evaluated from a mathematical model that describes the heat transfer into the system. The results indicate that the cycle time affects favorably the coefficient of performance as well as the apparent specific density of the sorbent and the reactor radius. Although the coefficient of performance values is low when compared to vapor compression cooling systems, the system can be operated by low temperature thermal sources, found in thermal solar collectors or flue gases, and it can increase the energy efficiency of industrial or residential applications. |
