The developed schematics for the solar refrigeration systems, based on the use of absorbing cycle and solar energy for the regeneration of absorbent solution are presented in the article. Cascade (two-stage) principle of construction of contours is used with growth of concentration of absorbent on the stages of cascade. The solar absorbing systems in the basic variants of cooling and air-conditioning are developed. Heat-mass-transfer apparatus of film-type, entering in the complement of contours compatible and executed on the basis of multichannel compositions from polymeric materials. The features of film-type flows in the heat-mass-transfer apparatus of the basic solar systems are considered theoretically. Experimental research of processes of heat and mass transfer in the apparatuses of drying (absorber) and cooling (evaporated coolers of air and water of direct and indirect types) contours of the solar system is executed. On the basis of findings on efficiency of processes the comparative analysis of the solar refrigeration and air-conditioning systems possibilities is carried out. Positive influence of growth of concentration of absorbent from the first to the second stage of cooling is shown. The preliminary comparative analysis of the solar refrigeration systems possibilities is proposed.Посилання
