Reasons and solutions for the increase in water temperature of cooling tower in summer

  With the arrival of summer, the weather became hot. When the user is using the cooling tower, the water temperature is too high and the chiller main high temperature alarm occurs. The main function of the cooling tower is to realize circulating water cooling through heat exchange, so that the water quality can reach the heat required by the chiller. When summer comes, the temperature of the cooling water becomes too high to meet the heat dissipation requirements of the main equipment. As equipment managers, they must face this problem and start from the working principle of cooling tower equipment to solve the thorny problem of excessive water temperature.QTjCooling tower noise reduction treatment manufacturer

  There is a big difference between using a cooling tower in winter and using it in summer. In winter, the entire ambient temperature is very low, and the temperature can be controlled within the specified range without opening the sprinkler system when the cooling tower is working. And in winter, wind cooling can neutralize most of the heat. When used in summer, when the ambient temperature is high, the heat exchange will be affected. Although the sprinkler system will be turned on to cool down when the temperature is high, what should be done if the sprinkler temperature still cannot be reduced? Don't worry, as an enterprise specializing in the research and development and production of cooling equipment, today Guangdong Trlon Energy-saving Air Conditioning Equipment Co., Ltd. will tell you in detail about the solution to the high temperature of the cooling tower in summer and difficult to cool down.QTjCooling tower noise reduction treatment manufacturer

  1. When the temperature is high in summer, if the cooling effect is not obvious, the spray system of the whole system should be turned on first. The spray system can effectively alleviate the problem of high temperature and rely on a large amount of cooling circulating water for heat exchange. The temperature can be effectively controlled. And when the temperature is controlled within the normal range, we can stop the spray system. Rely on air cooling and then continue to cool, and then turn on the spray when the temperature is high, so that the cycle can control the temperature and reduce the energy consumption.QTjCooling tower noise reduction treatment manufacturer

  2. The temperature can't be lowered even after opening the spray. The temperature in some areas in summer is very high, after the sprinkler system is turned on, the temperature still cannot be controlled within the normal range. At this time, the cooling capacity of the cooling tower has reached its limit. As the ambient temperature affects the cooling efficiency of the cooling tower, at this time we adopt the method of intermittently supplementing cold water. This will cause a certain amount of cooling water loss, but it can significantly reduce the temperature. If you want to consider the problem of water saving, we can install a thermal valve in the water outlet valve, and automatically control the supplement of cold water through the plc. After the temperature drops, the supplement of cold water will be automatically stopped.QTjCooling tower noise reduction treatment manufacturer

  3. The air volume of the fan will accelerate the air flow in the tower and accelerate the conversion of heat. The deflection angle, rotation speed and installation angle of the maple leaf will affect the air volume. When the air volume is the same and the type is the same, the cooling water volume is smaller than the larger cooling effect. We can appropriately adjust the design of the cooling tower.QTjCooling tower noise reduction treatment manufacturer

  4. The local wet bulb temperature should be considered in the initial design of the cooling tower, and the calculation should be carried out according to the summer temperature. The design temperature in the north wind area of ​​our country can generally meet the requirements, but it will be affected in the south of our country. The environment in the cooling tower is a high temperature and humid environment. There is a lot of rain in the south, the air humidity is high, and the temperature is high. This environment is just right It is similar to the environment inside the cooling tower, so it will have a certain impact on the heat exchange efficiency of the cooling tower. Therefore, the cooling tower needs to be designed slightly larger when selecting the cooling tower.QTjCooling tower noise reduction treatment manufacturer

  Seven reasons for the increase in water temperature of cooling towers in summer and solutions:

  Reason 1: The phenomenon of recirculation of hot air occurs.QTjCooling tower noise reduction treatment manufacturer

  Solution: Improve the ventilation environment and exchange hot air.QTjCooling tower noise reduction treatment manufacturer

  Reason two: insufficient air volume.QTjCooling tower noise reduction treatment manufacturer

  Solution: Adjust the angle of the fan blades within the rated current range of the fan.QTjCooling tower noise reduction treatment manufacturer

  Reason 3: The air inlet network of the cooling tower is blocked.QTjCooling tower noise reduction treatment manufacturer

  Reason five: the air volume of the fan is uneven.QTjCooling tower noise reduction treatment manufacturer

  Solution: Improve the ventilation environment to make the air volume uniform.QTjCooling tower noise reduction treatment manufacturer

  Reason 6: The circulating water volume of the cooling tower is too much.QTjCooling tower noise reduction treatment manufacturer

  Solution: Adjust the water volume to make the flow of the equipment meet the design standard.QTjCooling tower noise reduction treatment manufacturer

  Reason seven: the heat pipe is blocked.QTjCooling tower noise reduction treatment manufacturer

  Solution: Remove the dust and algae in the heat pipe and keep the heat pipe clean.QTjCooling tower noise reduction treatment manufacturer

  Guangdong Trlon Energy-saving Air Conditioning Equipment Co., Ltd. is a cooling tower manufacturer with many years of practical industry experience. When the cooling tower cooling water temperature is too high, it puts forward seven reasons and solves the problems one by one. Cooling towers are also prone to problems such as scaling and algae in summer, which is also necessary for regular maintenance of cooling towers. The commonly used circulating water treatment method is the chemical treatment method, which finally makes the cooling tower operate normally and proposes the cooling tower operating efficiency.QTjCooling tower noise reduction treatment manufacturer
