LOW-TEMPERATURE WATER EVAPORATIVE CHILLERS DEVELOPMENT AND THEIR FUNDAMENTAL CAPABILITIES ANALYSIS

Abstract

Conception of creation of the water evaporative chillers of new generation is worked out with the use of air-water heat-exchanger for the preliminary cooling of entering  air, at its unchanging moisture content. The natural limit of cooling in such systems is a dew of outward air point, that substantially extends capabilities of the evaporative cooling technique practical use as a whole and allows to decide the tasks of refrigeration and air-conditioning systems with a substantial power cost cutout on realization of processes and simultaneous decline of level of harmful ecological influence on an environment. In the evaporated cooler multichannel structures are used from polymeric materials. Traditional type and new generation  water chillers capabilities comparison   is executed at varying of initial parameters and correlation of gas streams  and liquid in the basic contours of the evaporative chillers.The special attention is spared to the issue of water vapor condensation on the satiation line in transition on the deep evaporative cooling of environments. The comparative analysis of such coolers capabilities is executed on the basis of theoretical and experimental data of the author, as it applies to the solution of evaporative cooling tasks.
