Abstract. The concepts of multifunctional dehumidification solar systems, heat supply, cooling, and air conditioning based on the open absorption cycle with direct absorbent regeneration developed. The solar systems based on preliminary drainage of current of air and subsequent evaporated cooling. The solar system using evaporative coolers both types (direct and indirect). The principle of two-stage regeneration of absorbent used in the solar systems, it used as the basis of liquid and gas-liquid solar collectors. The main principle solutions are designed for the new generation of gas-liquid solar collectors. Analysis of the heat losses in the gas-liquid solar collectors, due to the mechanism of convection and radiation is made. Optimal cost of gas and liquid, as well as the basic dimensions and configuration of the working channel of the solar collector identified. Heat and mass transfer devices, belonging to the evaporative cooling system based on the interaction between the film and the gas stream and the liquid therein. Multichannel structure of the polymeric materials used to create the tip. Evaporative coolers of water and air both types (direct and indirect) are used in the cooling of the solar systems. Preliminary analysis of the possibilities of multifunctional solar absorption systems made reference to problems of cooling media and air conditioning on the basis of experimental data the authors. Designed solar systems feature low power consumption and environmental friendliness.

Keywords: Multifunctional systems, solar energy, solar collectors, regeneration, evaporative cooling, polymeric materials.

Rezumat. Sunt elaborate schemele principale ale sistemelor multifuncţionale solare de uscare a aerului,de termoficare, de climatizare pe baza ciclului deschis absorbţional cu regenerare pentru generaţie nou a colectoarelor solare de tip „gas-lichid”. Este efectuat analiza pierderilor de c ldur în colectoarele menţionate, care sunt condiţionate de mecanisme de convecţie şi de radiaţie. Deasemenea sunt determinate debitele optimale de gaze şi de lichid şi dimensiunile principale şi configuraţie a canalului de cucru a colectorului solar. Aparatele de schimb cu c ldur şi cu masa, care fac parte a sistemul de racire evaporativ , sunt bazate pe interacţiune pelicular a fluxurilor de gas şi de ap în ele. Pentru crearea duzei sunt utilizate structurele cu multe canale fabricate din materialele polimerice. În partea ce r cire a sistemelor solare sunt utilizate materialele polimerice. În partea de r cire a sistemelor solare sunt utilizate evaporatoarele de r cire a aerului şi apei de tip direct şi indirect. Pe baza de date experimentale, obţinute de autorii analiza prealabil a posibilit ţilor sistemelor cercetate referitor la analiza problemelor de r cire a mediilor şi pentru climatizare a aerului. Sistemele elaborate au consumul de energie sc zut şi sunt ecologice..

Cuvinte-cheie: energie solar , regenerare, r cire evaporativ , colectoarele solare.
