A cooling tower is an installation that retreats heat from water by evaporation or conduction.
The industries use cooling water in various processes. As a result, there are also various types of cooling towers. There are cooling towers that create process water that can only be used once, before it is discharged. There are also cooling towers that create water that can be reintoduced in the production process.

Freshwater or central cooling system: Fresh water is used in a closed circuit to cool down the engine room machinery. The fresh water returning from the heat exchanger after cooling the machinery is further cooled by sea water in a sea-water cooler.
As discussed above, in the central cooling system, all the working machinery on ships are cooled down using circulating fresh water. This system comprises of three different circuits

The most common central cooling system is a split system, which includes an outdoor cabinet containing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with your furnace or air handler. The compressor pumps a chemical called refrigerant through the system.
emperature control of the process can be affected using electric, pneumatic, electro-pneumatic and self-acting controls. This Module details some common applications including process vessels, heat exchangers and high temperature fail safe control.

The water-cooled chiller uses water to take away the heat of the condenser refrigerant. The heat exchange capacity of water is 25 times that of air. Therefore, the water-cooled condenser can be made smaller than the air-cooled condenser, but it requires more water tower. And the cooling water pump power consumption refrigerant (R22 or 134A) through the chiller compressor output high-pressure refrigerant (high heat) through the condenser (water-cooled or air-cooled) to cool down and then use the law of physics to use an expansion valve or capillary expansion to cool the refrigerant again After the evaporator heat exchange and then back to the compressor
