The role of the cooling tower is equivalent to the heat exchanger of the outdoor unit of ordinary household air conditioners, which is used to dissipate heat.

For the incoming water of the water-cooled central air conditioner, the condensing side relies on the water in the water pump circulation pipe to take away the heat of the refrigerant in the condenser. After the water takes away the heat in the condenser, it circulates into the cooling tower under the action of the water pump Through the flow of water in the cooling tower, the heat is transferred to the air around the cooling tower, and then enters the central air conditioning condenser again to absorb the heat.

The cooling tower of the water-cooled central air conditioning system is equivalent to the condenser on the outdoor unit of ordinary household air conditioners, and the water pump is equivalent to the fan motor on the outdoor unit of ordinary household air conditioners, but it has changed from primary heat exchange to secondary heat exchange.

The water-cooled central version of the central air-conditioning cooling water system is an open system, and the water quality is easily deteriorated. It is necessary to clean the pipes regularly and replace the cooling water regularly.
