What is a cooling tower?

The cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the temperature of the water; its cooling is the use of water and air flow contact to perform cold and heat exchange to generate steam, steam volatilization Evaporative heat dissipation devices that take away heat to achieve evaporative heat dissipation, convective heat transfer, and radiant heat transfer to dissipate waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system.

Working principle:

By spraying the circulating water onto the glass fiber filler. The filler provides a larger contact surface, through the contact of water and air, to achieve a heat exchange effect. Then, a fan drives the airflow in the tower to circulate the hot air flow after heat exchange with water to achieve cooling. The filling may include multiple, mostly vertical, water-based elements on which the wet surface spreads (filling) or lateral splash elements create many cascades of thin layers (splashing) of small droplets with the large ground surface area.

Characteristics:

1. The water is in the packing in the tower, the water is from top to bottom, and the air is from bottom to top. The two flow to the opposite cooling tower.

2. The countercurrent cooling tower has good thermal performance and is divided into three cooling sections:

a. The space from the water distributor to the top of the packing, the water temperature in this section is high, so it can still transfer heat to the air.

b. Fill water and air heat exchange section.

c. Filling to the water spraying section of the sump space, where the water is cooled is called the "tail effect". In northern China, the water temperature can drop 1-2 oC. In summary, under the same conditions of the counterflow tower and the crossflow tower, the packing volume is about 20% smaller, and the heat exchange process of the counterflow tower is more reasonable and high in cooling efficiency.

3. The water distribution system is not easy to be blocked, the water-filling filler is kept clean and is not easy to age, the moisture backflow is small, and the anti-freezing and deicing measures are easier. Multiple units can be combined. In winter, according to the required water temperature and water volume, a single unit can be combined or all fans can be turned off.

4. Easy installation and maintenance, low cost, commonly used in air conditioning and industrial large and medium-sized cooling circulating water.

Main application:

Cooling towers are mainly used in air conditioning cooling systems, freezing series, injection molding, leather making, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling, etc. The most widely used are air conditioning cooling, freezing, plastic chemical industry. The specific division is as follows:

A. Air temperature adjustment category: air conditioning equipment, cold storage, cold storage room, freezing, heating and cooling air conditioning, etc .;

B. Manufacturing and processing: food industry, pharmaceutical industry, metal casting, plastic industry, rubber industry, textile industry, steel plant, chemical industry, petrochemical products, etc .;

C. Mechanical operation cooling type: generator, steam turbine, air compressor, hydraulic machine, engine, etc .;

D. Other industries ...

The function of the cooling tower is to exchange the cooling water carrying waste heat with the air inside the tower body so that the waste heat is transferred to the air and dispersed into the atmosphere.
