The three common forms of closed cooling towers are: countercurrent, cross-flow and compound flow. These three forms of closed cooling towers have their own advantages and characteristics. The staff of Wuxi Jiahe Cooling Equipment Co., Ltd. will share the differences of these three types of closed cooling towers with us below, so that users can make a better choice.
Whether it is open cooling tower or closed cooling tower, it is generally divided into cross flow and countercurrent two kinds. The so-called cross flow, that is, the inlet direction of the cooling tower is at a right Angle to the direction of the water flow. The cooling tower is suitable for civil central air conditioning, with small noise, simple structure and convenient maintenance. The countercurrent cooling tower, that is, the inlet direction of the cooling tower and the direction of the water flow is opposite, covers a small area, but the cooling tower noise is a little bigger, suitable for industrial cooling tower, such as casting, forging, heat treatment industry and so on.
Countercurrent closed cooling tower
Application scope: compact structure, small footprint, can be any combination of multiple sets, to meet the requirements of a variety of water, size and temperature difference, suitable for conventional cooling projects. Countercurrent cooling tower air intake form for the bottom countercurrent air, and the falling spray water reverse alternately form saturated hot and humid air, heat is discharged by the top fan, water by the special structure of dehydrator back to the collection tank recycling use, compact structure, small area;
Cross flow closed cooling tower
Scope of use: It is converted from cross-flow opening tower, suitable for multiple sets and combined to synthesize all kinds of water projects, the efficiency is relatively low. The working fluid flows in the coil, the outer wall of the coil is wrapped in spray water, the heat of the liquid is transferred through the tube wall, and the water and air form saturated hot and humid steam, the heat is discharged by the fan, the water is blocked back to the water tank circulation spray, consumption is very little, the process of the spray water circulation through the PVC radiator to reduce the water temperature, and the formation of feng shui vertical flow into the fresh air, The important feature of this operation principle is that it is very possible to inhibit the generation of scale on the outer wall of the coil.
Composite flow closed cooling tower
Application scope: Suitable for high temperature fluid cooling or large temperature difference projects, relatively high energy consumption, large volume. The closed cooling tower with low maintenance workload and mixed flow design is the most efficient closed cooling tower in the market. The mixed-flow cooling tower places the process refrigerant in a clean fully closed loop, which is free from pollution. At the same time, it integrates the functions of the cooling tower and heat exchanger in one body, with excellent operation and maintenance performance.
Selection of countercurrent closed cooling tower, cross-flow closed cooling tower and compound flow closed cooling tower: as long as the requirements of modeling design are met, the cooling effect is the same, but it is recommended to choose cross-flow or compound flow closed cooling tower in areas with high temperature, and choose countercurrent closed cooling tower in general areas.
The above is about the introduction of three common closed cooling towers. Do you know more about them? If you want to consult more about the cross-flow closed cooling tower, countercurrent closed cooling tower, compound flow closed cooling tower, welcome to the official website for understanding.
