MAISOTSENKO CYCLE FOR COOLING PROCESSES

ABSTRACT

The Maisotsenko Cooling cycle combines the thermodynamic processes of heat exchange and evaporative cooling in a unique indirect evaporative cooler resulting in product temperatures that approach the dew point temperature (not the wet bulb temperature) of the working gas. This cycle utilizes the enthalpy difference of a gas, such as air, at its dew point temperature and the same gas saturated at a higher temperature. This enthalpy difference or potential energy is used to reject the heat from the product. Consider the cooling gas to be air and the liquid to be water; the Maisotsenko Cycle allows the product fluid to be cooled in temperature ideally to the dew point temperature of the incoming air. This is due to the precooling of the air before passing it into the heat-rejection stream where water is evaporated. For purposes of this paper, the product fluid is air. At no time is water evaporated into the product airstream. When exhausted, the heat rejection airstream or exhaust air is saturated and has a temperature less than the incoming air, but greater then the wet bulb temperature. This cycle is realized in a single apparatus with a much higher heat flux and lower pressure drop than has been realizable in the past due to its efficient design.
