As we all know, the discovery of the closed cooling tower originated from the evaporative cooler, which is a heat exchanger that combines the performance of a water-cooled cooler and a conventional cooling tower, and is often referred to as an evaporative air cooler.
Using this principle, the glass fiber reinforced plastic cooling tower used in the factory has gradually evolved. Today's cooling towers are divided into two types: open type and closed type. What are the different performances between the two? Xiaobian will briefly tell you today.
1. The main cooling medium is in a closed pipe for a long time and does not contact with air. The heat is generally exchanged with the spray water through the pipe wall of the heat exchanger, so it directly forms the effect of cooling and cooling. It is more convenient for daily management.
2. It does not need to be shut down frequently to maintain and maintain it. It is relatively stable and safe to operate, and it can also reduce the failure rate of associated equipment. It is usually more suitable for continuous operation of related systems.
3. Because it is a closed system, it is not often in direct contact with the air, so that there will be no algae and salt crystallization, so there is no need to remove algae and salt in the later cleaning, which is very good. Maintenance of related equipment operation.
1. The cooled medium of the open cooling tower is concentrated due to evaporation and needs to be replenished all the year round. Since the cooled medium is in direct contact with the air, when it encounters rainy days, the fluid will have a corresponding acid reaction and will cause damage to related equipment.
2. Routine shutdown maintenance is required, and open cooling towers are not suitable for continuous operation systems.
3. The cooled medium is mainly operated in an open type, and is often exposed to sunlight, which is easy to produce algae and salt crystals, which will affect some performance.
4. There is no way to run dry.
5. When the fluid is a volatile and irritating solution, there will be some safety hazards if the open cooling tower is operated at this time.
6. The cooling medium is circulated in the open type, and the internal system pipes are prone to scaling, which in turn reduces the heat exchange efficiency of the cooled equipment, so it is necessary to do a good job of cleaning in time.
