The three common types of closed cooling towers are: counterflow, cross flow and composite flow. These three types of closed cooling towers have their own advantages and characteristics. I will share these three by the editor of Teling Air Conditioning. The different parts of a closed cooling tower are convenient for consumers to make better decisions.
Whether it is an open cooling tower or a closed cooling tower, there are usually two types of cross flow and counter flow. The so-called cross flow, that is, the angle of the air inlet of the cooling tower is at right angles to the angle of the water flow. This type of cooling tower is suitable for civil central air conditioning. Low noise, simple structure and convenient maintenance. The countercurrent cooling tower, that is, the angle of the air inlet of the cooling tower and the angle of the water flow are exactly the opposite, and it occupies a small area, but the noise of the cooling tower is a little bit louder. It is suitable for industrial cooling towers, such as casting and forging, heat treatment industries and so on.
Countercurrent closed cooling tower
Scope of application: compact structure, small footprint, several units can be combined at will, to achieve a variety of water volume, large and small temperature difference regulations, suitable for conventional cooling projects. The air inlet type of the counter-flow cooling tower is the bottom counter-flow air inlet, which alternates with the falling spray water to generate saturated hot and humid air. The heat is discharged by the top fan, and the water is blocked by the specially constructed water trap to circulate the water collection tank. The structure is compact. , Occupies a small area;
Cross flow closed cooling tower
Application range: Transformed by a cross-flow open tower, suitable for projects where several units are arranged in parallel to form a variety of water volumes, and the efficiency is correspondingly low. The working fluid flows in the coil, and the outer wall of the coil is wrapped by spray water. The heat of the liquid is transferred through the pipe wall to generate saturated hot and humid steam with water and air. The heat is discharged to the atmosphere by the fan, and the water is blocked back to the water collection tank and sprayed circularly. In the process of spraying water, the consumption is very small. During the process of spraying water circulation, the water temperature is reduced by the PVC heat sink, and the wind water generated by the fresh air flows perpendicularly. The important feature of this operating principle is that it is likely to inhibit the formation of scale on the outer wall of the coil.
Composite flow closed cooling tower
Scope of application: It is suitable for the cooling of high-temperature fluids or projects with large temperature differences, with correspondingly higher energy consumption and larger volume. The closed cooling tower with low maintenance workload and mixed flow design is the most efficient closed cooling tower on the market. The mixed-flow cooling tower puts the process refrigerant in a clean and fully enclosed circuit to avoid contamination, and at the same time integrates the functions of the cooling tower and the heat exchanger, and has the operation and maintenance performance.
The decision of counter-flow closed cooling tower, cross-flow closed cooling tower and composite flow closed cooling tower: as long as the design requirements are realized, the cooling effect is the same, but it is recommended that the area with relatively large temperature decides the cross-flow or composite flow closed cooling tower , Usually the area chooses the countercurrent closed cooling tower.
