Cooling tower means cooling tower is a water cooling device in the English literal sense, cooling means cooling and tower means tower or structure.
Cooling towers or cooling towers are basically water cooling devices that transfer the heat generated by the condenser to the open environment. To cool again, it returns to the cooling tower. Hot water circulates in the tower and is poured from the top of the tower to the bottom, as a result of which water falls from the inner cover of the cooling tower and collides with the air. Transfers
In short, the purpose of the Koolig Tower is to cool the water that is heated by the factory equipment during industrial processes, and in general its task is to cool the water. Given that the temperature and humidity of the air passing through this system increases, it is obvious that the amount The effect of the device largely depends on the humid temperature of the inlet air and increases as it decreases.
Cooling towers have different types and due to the advancement of engineering science and technology, significant changes have been made. Cooling towers are produced in concrete, galvanized or fiberglass structures. Today, the products of this refrigeration product are often offered with a composite body (fiberglass). Fiberglass in the structure of the cooling tower body increases the strength and resistance of the body against water corrosion and also increases the life of the body.
The cooling tower consists of several parts, the most important of which are:
• Fan: is a mechanism for forced movement of air inside the cooling tower. It is either of the axial type (suction) which is located at the top of the tower or of the centrifugal type (blower) which is installed in front of the tower.
Application of cooling tower in industry
Fluids for cooling in refinery air conditioners. Petrochemical Industries . Power plants, etc. are used to heat up due to circulation and its temperature rises. Industrial cooling tower or industrial cooling tower lowers the temperature of these fluids by evaporating water to near the bubble temperature and enters the absorbed heat into the environment. In various oil and gas industries, liquid oxygen production, wood parts production and foam production Industrial Cooling Towers have many applications, which may sometimes be represented as a concrete structure and sometimes may be seen as one or more fiberglass cooling towers in different industries.
Cement companies such as Lamerd Cement, Sabzevar Cement, Prietland Cement and other various cement industries in the construction industry use cooling towers to cool the processing of concrete operations and cement production. In the wood industry and the production of chipboard and industrial fibers, in special adhesive production furnaces, cooling towers are used to cool the adhesive tank. In the food industry, to cool the tanks of whey, milk, etc., cooling towers are used to cool the devices. Pasteurization is used.
Select Cooling Tower
Choosing a cooling tower in any project is a challenge between the initial cost of running costs and maintenance. In choosing a cooling tower, parameters such as the type of tower (evaporative air) the amount of heat transfer by the tower. Flowing water flow .Wet and dry ambient temperature. Inlet water outlet (Delta T) is very important in determining the cooling capacity of the cooling tower
To ensure the optimal use and proper operation of the chiller, choosing a cooling tower or cooling tower with a higher operating capacity will be cost-effective. Using a motor for the cooling tower fan that turns off frequently will reduce the efficiency of the tower, but To increase it, a three-stage motor or continuous speed can be used using the inverter system.
Due to the fact that the temperature and humidity of the air from the tower increases, it is obvious that the effect of the cooling tower largely depends on the humid temperature of the inlet air and increases with its decrease and other factors that affect the performance of the cooling towers. Put are:
1. Level and time of weather contact
2. The speed of the air passing through the tower
3. The direction of air flow relative to the water contact surface (both sides and sides)
Water-to-air contact surface includes:
1. Water level in the tower pan
2. All wet surfaces in the tower
3. The whole surface of the water droplets sprayed on the tower.
Theoretically, the lowest temperature that can be achieved for water in the cooling tower is the humid temperature of the inlet air, in which the exhaust air condition will be saturated with water vapor, but often the outlet water temperature from 4 to 5.5 ° C is higher than the humid inlet air temperature. is. Therefore, the exhaust air from the tower will always be slightly lower than the saturation state.
Note: The lower the optimum temperature of the tower inlet air, the higher the efficiency of the tower, so in humid areas, water condenser is not economical and air condenser is used.
