How to operate a closed cooling tower in the cold winter season

  What is a closed cooling tower? Do you know that it is divided into operation methods in severe cold and other seasons. If you want to know the operation methods in severe cold season, the editor of trlon below gives you a brief introduction to the content below, and I hope to help you.JN2Cooling tower noise reduction treatment manufacturer

  Cold and freeze protection for fan coilJN2Cooling tower noise reduction treatment manufacturer

  The fan coil is an expensive accessory in the closed cooling tower, so be sure to avoid freezing and bursting. Draining the fan coil is a way to avoid freezing, but it is restrictive. Evacuation of galvanized steel pipes should only be carried out in emergency situations, and should not be regarded as a small part of the standard operating procedures, because the fan coils are not galvanized and will quickly rust. If necessary, stainless steel and copper coils can be emptied, but this process is not simple and requires proper machinery and equipment modifications.JN2Cooling tower noise reduction treatment manufacturer

  Water pan cold and frost protectionJN2Cooling tower noise reduction treatment manufacturer

  Although ethylene glycol can prevent the material in the coil from freezing and protect the fan coil, the external circulating water pan is not protected from cold and frost. If the external circulating water tray is not emptied in winter, it is likely to require the use of resistance or steam heaters to avoid freezing of the external circulating water system when the closed tower is not operating, and the required input of the water tray The heat is determined by the natural environment and can be found in the data sheet of the selected closed tower. Or, the external circulating water can be discharged into a sump or heated building to avoid freezing of the external circulating water.JN2Cooling tower noise reduction treatment manufacturer

  Further researchJN2Cooling tower noise reduction treatment manufacturer

  Because it is more difficult to drain the closed tower fan coil and there are corresponding risks, compared to some applications such as HVAC water source heat pumps, generally speaking, the common method is to run the boiler fluid substance in the closed tower. When doing so, the external circulating water can be emptied, or heated appropriately, because the cooling fan coil is no longer required. In addition, because the boiler heat will be lost through the fan coil, a damper is installed to avoid air circulation around the fan coil. Although the damper can avoid most of the heat loss, the insulation material can further avoid heat loss. These two technologies will make the heat loss of the fan coil smaller, and can avoid the boiler large-scale and increase energy consumption cost.JN2Cooling tower noise reduction treatment manufacturer

  The above is the operation method of closed cooling in severe cold season introduced by trlon editor. Trlon has a group of professional scientific research and development, production and manufacturing elite teams, R&D and design department, manufacturing department, quality inspection department, sales department and after-sales service Other departments are led by employees who have years of experience in water-cooled machinery and equipment, and have a cooling tower R&D center and thermal performance test platform to ensure that the cooling tower performance meets the requirements of the working conditions.JN2Cooling tower noise reduction treatment manufacturer
