The cooling towers commonly used in air conditioners mainly include the following types:
1. DC cooling tower: DC cooling tower is a common type of cooling tower. Its working principle The hot water is circulated from the cooling equipment to the cooling tower through a water pump, and the water is sprayed onto the filling layer through the spray system to fully contact the water with the air to achieve the purpose of heat dissipation.
2. Closed cooling tower: A closed cooling tower is a relatively environmentally friendly cooling tower. It uses a closed circulation system, which can effectively reduce water waste and environmental pollution. Closed cooling towers can be divided into two types: cooling water circulation type and air circulation type.
3. Wet cooling tower: Wet cooling tower is a high-efficiency and energy-saving cooling tower that uses the evaporation of water to reduce the temperature of the air to achieve the purpose of heat dissipation. Wet cooling towers usually adopt a packed structure. Water is sprayed on the filling layer to fully contact the water with the air. The water takes away heat during the evaporation process, thereby achieving the heat dissipation effect.
4. Dry cooling tower: A dry cooling tower is a heat dissipation equipment that does not use water. It uses a fan to blow air across the surface of the radiator so that the air fully contacts the heat exchanger, thereby To achieve the purpose of heat dissipation. Dry cooling towers usually use aluminum alloy or copper tubes as radiator materials, which have the advantages of simple structure and easy maintenance.
In short, the commonly used cooling towers for air conditioners mainly include once-through cooling towers, closed cooling towers, wet cooling towers and dry cooling towers. Choose the appropriate cooling tower according to actual needs.
