This paper presents experimental analysis of various adsorbent and adsórbate pairs for refrigeration systems. The most proper adsorption theory for analyzed working pairs is presented. This article shows adsorption isotherms for activated carbon, silica gel and zeolite with methanol. Correlations relating pressure dependence of adsorption potential have been obtained with the help of McBain-Bakr spring balance (providing a continuous record of the quantities and rate of sorption). Using the experimental results and the BET theory surface area and pore volume are calculated. The characteristic curve has been applied to determine the whole thermodynamic description of the sorption pair. More complex assessment of working pairs is possible, when the cycle for specific conditions is modeled. To display the cycle of adsorption system, Clapcyron diagram P-T-x is used on which isosteres of adsorption are straight lines. The performance of an adsorption system is controlled by many parameters such as refrigerant, adsorbent thermophysical properties, system design and operating conditions. Based on the results of thermodynamic analysis and experimental results the coefficients of performance as well as the amount of useful heat for activated carbon, silica gel and zeolite with methanol have been presented. Conception of solar systems for refrigeration and heat pumping based on adsorption and desorption of gas from solid has been proposed.
