Краткое описание

In any explanation of cooling tower operation, it is shown that the ambient wet bulb temperature is a physical limit for water cooling. The main advantage of the Maisotsenko cycle (M-cycle) is the possibility to have the cold water temperature lower than the ambient wet bulb temperature, without violation of any physical principle. The idea is based on the fact that the ambient wet bulb temperature depends not only on the absolute humidity value, but also on a current air temperature. On the contrary, the dew point temperature depends only on the absolute humidity value. If we can provide lower temperature of the air (with the same absolute humidity) at the air inlet of the cooling tower, then the wet bulb temperature for such air will be lower. Therefore, if we can cool the air entering the cooling tower, without the change of its absolute humidity, it will be possible to cool the water more and, for some conditions, its temperature could be lower than the wet bulb temperature of the surrounding air at some distance from the cooling tower. However, the main problem is how to cool the air entering the cooling tower, very simply and without significant energy consumption. A theoretical possibility to solve this problem by application of the M-cycle is under analysis in this paper.
