Reliable owner for air conditioning cooling

Closed cooling towers are essential equipment in industrial cooling systems. They provide effective heat exchange solutions through a closed circulation system. This type of equipment is mainly composed of the following key components:1. Heat exchange coil: This is the core part of the closed cooling tower, responsible for transferring the heat of the medium (such as oil or water) that needs to be cooled to the environment. The coil is usually made of corrosion-resistant materials to cope with chemical corrosion in various industrial environments.2. Fan: The function of the fan is to drive air flow and accelerate the dissipation of heat. An efficient fan can ensure good air flow through the heat exchange coil, thereby improving cooling efficiency.3. Shell: The shell protects the internal components from the influence of the external environment, such as weather changes, dust, etc. The shell is usually made of carbon steel anti-corrosion material or fiberglass to ensure long-term durability and safety.4. Spray water pump: The spray water pump transports desalted water to the upper part of the closed cooling tower, increases the contact area between water and air by spraying, and improves cooling efficiency.5. Internal filler: The filler is used to increase the contact area between water and air and optimize the heat exchange process. Good packing design can significantly improve cooling effect.In summary, these components work together to ensure that the closed circuit cooling tower can operate efficiently and provide good cooling solutions for various industrial applications. Proper maintenance and regular inspection of these components are important to maintain the good performance of the equipment.

Closed cooling towers are an essential component of industrial and commercial refrigeration systems. They dissipate heat through a circulating water system to keep the equipment running at a suitable temperature. The amount of cooling water is critical to the performance of the equipment because it directly affects the heat exchange efficiency and the cooling capacity of the system.In a closed cooling tower, cooling water is usually pumped to the nozzle at the top of the tower and then evenly distributed on the packing layer. As the water flows through the packing and the air flows in the opposite direction, heat is transferred from the water to the air, thereby achieving cooling. If the amount of cooling water is insufficient, the water film will not be able to completely cover the surface of the packing, reducing the contact area between water and air, thereby reducing the heat exchange efficiency. On the contrary, if the amount of water is too large, although the contact area between water and air can be increased, it will also increase the energy consumption of the water pump and may cause excessive water droplets to be entrained in the tower, affecting the normal operation of the equipment.Therefore, in order to ensure the efficient operation of the closed cooling tower, the appropriate amount of cooling water should be determined according to the specific environmental conditions and system requirements. This usually involves a comprehensive consideration of factors such as the design parameters of the equipment, climatic conditions, inlet water temperature, outlet water temperature, and required cooling load. By accurately controlling the amount of cooling water, not only can the cooling efficiency be improved, but also energy consumption can be saved and the life of the equipment can be extended.Please indicate the source for reprinting: https://www.htcoolingtower.com/

The air inlet of various types of closed cooling towers may freeze. The air inlet of natural ventilation counterflow closed cooling towers usually freeze at the lower edge of the inner wall of the tower, or hang ice at the edge of the retaining eaves inside the tower. When it is light, it forms a thin ice curtain; and when it is serious, it freezes with column A of the tower to form an ice wall in the cross-flow cooling tower. There is ice in the inner edge of the louver of the inlet of the cross-flow cooling tower. Because the hard part of the cooling tower is water leakage, a large area of ice is formed on the side of the inlet column and the louver. The main reason for the intake icing is that the water around the packing of the cooling tower is too small, and a small amount of water flowing down the wall of the cooling tower stays in the intake for a long time. Upper edge or spout edge.If the heat load and water quantity of the whole tower is too small, the bottom of the pouring water packing of the whole tower will hang ice; Some use zoned water distribution cooling tower, because of uneven water distribution, will make part of the packing frozen. When the casting density is small, the cold air will invade first. In other areas with low watering density, it is easy to form freezing damage to plums, such as water tank blockage and damage. If the nozzle is blocked and the water tray falls off, it is easy to cause local freezing damage. If the local water of the pouring filler is too small or the pouring filler column is close to the air inlet, it is easy to cause the packing supporting beam column and part of the packing to freeze.An ice cone is formed on the inner and outer edges of the rigid ring at the top of the cooling tower. Due to the accumulation of water vapor, natural ventilation is carried out. In the mechanical ventilation cooling tower, the effect of the secondary tower part of the dehydrator is poor. With the air out of the tower, water drops fly out of the tower and fall on the platform on the top of the tower and the exhaust pipe of the fan, causing ice. The high efficiency dehydrator and the double wave dehydrator installed in the packing high wind speed area can eliminate the floating drops and solve the icing problem on the top of the tower.Because water separators are not installed or are ineffective, large drops of water fall on the surrounding ground, or vortices at the air intakes carry some of the droplets out of the tower and onto the ground. When multiple grilles in cooling towers are ventilated mechanically, some grilles will not operate in winter. Water vapor from the running tower falls on the fan blades in the stopped tower and accumulates on the surface area of these blades, so it freezes. If the blade on the ice from melting, static, dynamic balance of the blade will be out of balance, serious when bow | fan vibration and damage of the tower structure.When cooling towers are out of service in winter, the water-filled circulation ditches, pressure lines and valves can freeze because the water does not flow and cannot be replenished. The lateral frost heave force caused by freezing can reach 0.2 ~ 0.3MPa, causing damage to the equipment.
