The cycle characteristics of thermochemical resorption refrigeration system were investigated, and the experimental comparison between the basic resorption cycle and adsorption cycle was performed. Experimental results showed that the conversion rate during the regeneration phase in the resorption refrigeration cycle was higher than that in the ...

Ionocaloric refrigeration cycle
Science, 2022Developing high-efficiency cooling with safe, low–global warming potential refrigerants is a grand challenge for tackling climate change. Caloric effect–based cooling technologies, such as magneto- or electrocaloric refrigeration, are promising but often require large applied fields for a relatively low coefficient of performance and adiabatic ...

An ideal reversible cycle based on the two temperatures of the system can be drawn on a temperature–entropy basis. In this cycle a unit mass of fluid is subjected to four processes after which it returns to its original state. The compression and expansion processes take place at constant entropy.

The chapter presents the development of ejector refrigeration technology that strongly reduces the greenhouse gases emission by using natural refrigerants and also dramatically reduces the need for the electric power. This is accomplished by using free or inexpensive heat – either solar or waste heat, as the main source of energy instead of electricity.

Optimal synthesis of refrigeration cycles and selection of refrigerants
AIChE Journal, 1999AbstractThe optimal synthesis of the refrigeration configuration and the selection of the best refrigerants that satisfy a set of process cooling duties at different temperatures is addressed. This approach simultaneously selects refrigerants and synthesizes refrigeration structures by minimizing a weighted sum of investment and operating costs.

This chapter describes a collaborative effort of US private companies and various departments of the US Government to investigate the possibility of improving the efficiency of HVAC systems by use of one and two-phase ejectors. It is anticipated that this technology, when fully developed will result in attractive, energy saving products that ...

Optimization of the specific rate of refrigeration in combined refrigeration cycles
Energy, 1995The optimization problem of a combined refrigeration cycle formed by two endoreversible Carnot refrigeration cycles in series without intermediate reservoirs has been studied using finite-time thermodynamics. The fundamental relation between cooling quantity and coefficient of performance (COP) of the combined cycle is derived for a general physical ...
