Evaporative coolers of gases and liquids with a lowered level of cooling

Abstract

Evaporative coolers of gases and liquids with a lowered level of cooling This study is dedicated to the creation of the schematic solutions of the evaporative cooling and air conditioning systems, development of the heat and mass transfer equipment for such systems, experimental investigation and analysis of principle possibilities of such systems on the basis of carried out theoretical and experimental research. The theoretical modeling of the coupled heat and mass transfer process in indirect evaporative coolers of water and air is carried out. It is shown that the dew point temperature of the air flow entering the evaporative cooler can be served as a limitation of cooling. The difficulties connected with obtaining the cooling limitation for low-temperature cooling connected with the possible condensation of water vapor in the air flows, when the air flow contacting with water becomes fully saturated before going out from the heat and mass transfer device, are studied.
