The Effect Of Cooling Tower Wet Ball Temperature On Cooling Ability
[Description of the problem of wet ball temperature on the cooling ability] Many users react to us when using a closed cooling tower, when it is cloudy or rainy weather, the cooling effect of the closed cooling tower will be affected, especially when it rains in the rain At the time of the cooling ability, the cooling capacity can be about doubled under normal circumstances. Especially in the southern region, the influence of the rainy season. If the selection of the closed cooling tower is relatively small, it may cause the cooling temperature to not achieve the expected effect.
The minimum cooling temperature of the closed cooling tower is the temperature of the wet ball+3 degrees Celsius. When the temperature of the wet ball is changed by the meteorological conditions, it will affect the cooling effect of the closed cooling tower. When the temperature of the dry ball of the air environment changes, the temperature of the outlet of the closed cooling tower is detected, and the temperature changes very small, which can generate a maximum of 1-2 degrees of the cooling temperature difference.
- In rainy weather, when the temperature of the dry ball is similar to the temperature of the wet ball, the cooling capacity decreases significantly. Cause Analysis:
In rainy weather, the temperature difference between the temperature of the damp ball and the temperature of the dry ball is relatively small. The pressure of water vapor in the air increases the pressure and the effect of quality transmission has decreased, resulting in a decrease in evaporation water in the closed cooling tower, resulting in heat dissipation, resulting in heat dissipation If the amount is reduced, the temperature of the outlet will rise, which is the manifestation of the decreased cooling capacity.
- In the sunny weather, the temperature difference between the dry ball temperature and the temperature of the wet ball, and the cooling ability is better.
Cause Analysis:
In the sunny weather, the temperature of the dry ball will definitely be higher than the temperature, and the temperature difference will be relatively large. The air is relatively dry and the water contains less water. Therefore, the pressure of water vapor in the air is also relatively small. The speed of spraying and evaporating water has accelerated, the heat dissipation increases, and has a better heat transfer effect, so it has a better cooling effect.
