Description

technical field [0001] The invention relates to a dry-wet combined air-cooling integrated device with cold storage and antifreeze functions and a cooling method thereof, belonging to the technical field of general heat exchange. Background technique [0002] According to whether the circulating water system is in contact with the atmosphere, the circulating cooling water system can be divided into an open circulation system and a closed circulation system. An open circulation system generally uses an evaporative cooling tower as a heat dissipation device for circulating water. The water is in contact with the atmosphere, and the amount of evaporated water is large. In the closed circulation system, the circulating water does not directly contact the atmosphere, but conducts indirect heat exchange through the partition cooling coil, and the air and part of the cooling spray water are used as the cold source to take out the heat of the circulation system to achieve For coolin...

AI Technical Summary

Problems solved by technology

[0004] 1) It is greatly affected by the temperature difference between day and night and four seasons. In order to meet the cooling demand throughout the year, the design of the air cooler is often based on the hottest weather conditions, resulting in large-scale equipment and high investment costs. When the ambient temperature is low, there are The problem of large ineffective energy consumption

[0005] 2) The air cooling efficiency is low. In summer or when the temperature peaks at noon, the cooling capacity is insufficient and the peak cutting ability is poor;

[0006] 3) When the heat source user shuts down for maintenance in winter, the circulation system loses the continuous heat source, the temperature in the tube bundle and the pipeline drops, and the pipe freezing phenomenon is very likely to occur, so it is necessary to install an antifreeze device, while the traditional heat tracing or steam antifreeze device consumes a lot of energy and costs a lot of investment. high;

[0007] 4) After the spray air cooler is used for a long time, the surface of the tube bundle or the surface of the fin will be scaled, which will seriously affect the heat exchange efficiency and the cleaning is complicated
