Differences between evaporative condensers and closed-loop cooling towers

When there is a phase change (condensation) of the cooling medium inside the tube, it is called an evaporative condenser. The evaporative condenser is a compact heat exchanger that combines the features of air-cooled and water-cooled systems; it replaces the traditional refrigerant condensation method that involves a shell-and-tube condenser together with a cooling tower. It relies on the latent heat of evaporation of water sprayed outside the tubes to remove heat, and by eliminating one heat exchange step, it offers advantages in terms of energy and water savings. The closed-wet cooling tower, abbreviated as CWCT, originates from industrial evaporative coolers and is used as a term in contrast to open-type cooling towers. As an indirect-contact cooling tower, it replaces the packing found in conventional cooling towers with a heat exchange coil assembly ； The target applications are mainly those that require high cleanliness of the cooling water or high precision in controlling the cooling water temperature, and where conventional open-type cooling towers are not suitable. Since their heat transfer mechanism is the same as that of industrial evaporative coolers and their applications are similar, in essence, evaporative coolers/closed-type cooling towers are simply two different names for the same type of equipment.

There is indeed a difference between phase transitions and those without phase transitions.

It’s this difference; in terms of production, it’s all the same

Born on the buttocks, it’s called hemorrhoids; born on the back, it’s called boils. That’s the difference. Ha

How to calculate it? I’ve read many professional explanations from university professors, but the more I read, the less I understand. Is there anyone who can explain it clearly? ?
