Refrigerant condenses inside a coil.

Water is sprayed over the outside of that coil.

Air is drawn through the same section.

Evaporating water removes the heat directly.

It happens in one machine on one surface.

A cooling tower and a separate condenser.

The conventional route moves heat twice.

Refrigerant to water, then water to air.

Here those two steps become one.

The intermediate water loop disappears.

Every heat transfer needs a temperature difference.

Removing one lets the plant condense lower.

Compressor power depends on condensing temperature.

The saving is continuous, not occasional.

Condenser water pumping is avoided as well.

Refrigerant has to travel to the condenser.

That is usually outdoors and often on a roof.

The circuit is longer and the charge is larger.

Part of it runs outside the plant room.

Leak detection and safety provisions follow from that.

In industrial refrigeration.

Cold stores, food processing and ice plants.

Long refrigerant circuits are already normal there.

Loads run continuously enough to reward efficiency.

Comfort cooling uses it far less often.

Yes, in every respect.

It is a wet outdoor machine.

Water treatment and testing apply equally.

Scale on the coil directly costs capacity.

Winter provisions are the same as well.

It condenses at a lower temperature for the same weather.

Evaporation reaches below the dry air temperature.

That is worth real compressor energy.

An air-cooled condenser needs no water at all.

The choice is efficiency against water obligation.
