Convection cooling tower mechanics have large fans to exhaust domestic forced circulation. Water flows down on the surface of the fill, which increases the contact time between the water and air-help maximize the heat transfer between water and air. The rate of cooling tower mechanical convection depends on many different parameters such as fan diameter and speed of operation, the fill becomes the system's capacity.
- Mechanical convection tower now available with a range of wide productivity. Towers could be built at the factory or field - such as the concrete tower was built only in the field. Many towers are built in a way that can work together to achieve the desired capacity. So a lot of cooling towers are assemblies of two or more separate towers, called "cell" number of cells, such as cell towers 8 refers to such towers. The multiple cell towers can row, square or round depending on the shape of the cell and, depending on the air inlets are located on the side or bottom of the box.
There are three types of mechanical tower as summarized in Table 1 .
Table 1. key features or different types of cooling towers (according AIRAH)
type cooling tower Advantages Disadvantages
cooling towers forced convection (Figure 4): air is sucked into the tower by a fan located Suitable inlet section with high air resistance due to centrifugal blower
fans are relatively quiet the traffic due to high air velocity and a low air velocity, can be resolved by placing the towers in the chamber of the wire exhaust pipe and passed along with the
ventilation cooling towers ?? horizontal line (Figure 5):
Water enters at the top and go through the buffer block.
the air enters from one side (tower one line) or from the opposite side another (tower two lines) A fan draws air in through the fill up the exit at the top of the tower honthap poor circulation forced convection air speed because racao 3-4 times more air into fan and adapters motor control is needed against weather conditions, humidity and corrosion because they are placed in a moist airway
ventilation cooling towers upstream (Figure 6):
Hot water enters the upper part. Air enters the bottom and out at the top. Use exhaust fans and blowers
