A cooling tower is a device that uses water as a circulating coolant and absorbs heat from a system and discharges it to the atmosphere to reduce the temperature of the water. Its cooling is the use of cold and heat exchange between water and air to generate steam. The principle of heat dissipation, convective heat transfer and radiant heat transfer is an evaporative heat sink that dissipates excess heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower.
Cooling towers are mainly used in air-conditioning cooling systems, refrigeration series, injection molding, tanning, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling and other fields. The most widely used are air-conditioning cooling, refrigeration, plastic chemical industry .
The specific division is as follows:
A. Air room temperature regulation: air-conditioning equipment, cold storage, refrigerating room, freezing, heating and cooling air conditioning, etc .;
B. Manufacturing and processing: food industry, pharmaceutical industry, metal casting, plastic industry, rubber industry, textile industry, iron and steel plant, chemical industry, petrochemical products, etc .;
C. Mechanical operation cooling category: generator, steam turbine, air compressor, oil compressor, engine, etc.
D. Other industries
The role 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 transmitted to the air and dispersed into the atmosphere.
