When selecting and designing a closed cooling tower, the influence of environmental meteorological conditions such as the customer's local wet bulb temperature is generally considered. These factors have a greater impact on the cooling efficiency and safe operation of the closed cooling tower. There is a big difference in climate and temperature between the north and south of my country. Therefore, closed cooling towers are used in different regions and have different response measures. Ecomic will talk to you about the impact of regional conditions on the cooling efficiency of closed cooling towers. 1. The relationship between cooling effect and local climate temperature. The cooling tower is an evaporative air cooling equipment. The basic condition for cooling is the evaporation of water to dissipate heat and cool down. The evaporation of water has a great relationship with the ambient wet bulb temperature. Generally speaking, the lower the wet bulb temperature, the stronger the evaporation capacity, and the higher the cooling efficiency of the cooling tower. Therefore, in the northern low-temperature and dry climate environment, the cooling tower efficiency is the highest, while in the southern hot and humid climate environment, the cooling tower efficiency is the lowest. Therefore, when choosing a cooling tower in the south, it is often necessary to enlarge the tower type, while in the north, a smaller tower type can be used to achieve greater cooling capacity. In other words, temperature and humidity will affect the cooling efficiency of the closed cooling tower. 2. Regional differences in icing problems not only affect the cooling efficiency of cooling towers, but also require cooling tower manufacturers to consider regional climate differences when designing. We all know that northern regions tend to have low winter temperatures, with winter temperatures often reaching minus 10 degrees Celsius or even lower. In this climate, if the user's cooling system shuts down unexpectedly, there will be no time to drain the circulating water from the system, and the consequences will be very serious. In most cases, the cooling coils of closed cooling towers will freeze and burst, causing equipment damage. In severe cases, all closed cooling towers will be scrapped, forcing users to stop work and production for a long time, causing immeasurable losses to users. Fortunately, the detachable plate-type closed tower designed and produced by Shenzhen Ecomic Technology Co., Ltd. has the characteristics of anti-icing and no pipe explosion after freezing, eliminating the hidden danger of freezing in winter for users. Therefore, when choosing a closed cooling tower, users should try their best to choose equipment without hidden dangers. 3. Regarding the issue of dry air cooling, we know that the heat dissipation of cooling towers has a great relationship with the ambient temperature. Especially for closed cooling towers, the lower the ambient temperature. The higher the cooling efficiency, when the ambient temperature reaches a certain level, users often want to use dry air cooling directly without spraying water, which can save a lot of evaporation water loss. It is true that dry air cooling does not require spray water and can save nearly 1% of evaporation losses per hour. Large industrial users often use tens of thousands of tons of circulating water and evaporate hundreds of tons per hour, losing more than 20,000 tons of water every day. If losses can be avoided in the entire northern winter, millions of dollars can be saved in three months every year. However, the conventional closed cooling tower has almost no cooling effect without spray water. This is determined by its cooler structure. The convection heat exchange between the coil cooler and the air has almost no effect. A brand-new plate-type closed tower was successfully developed by Ecomic. In dry and cold conditions in winter, the heat exchange effect is completely comparable to that of wet and cold closed towers, so that users can safely save water loss in winter without affecting the user's cooling needs. In fact, the Ecomic plate closed tower can not only achieve dry air cooling in winter, but also use dry air cooling in spring and autumn when the temperature is low (the ambient temperature is lower than 15°C), saving water and energy. When the Ecomic closed cooling tower was designed, the spray system was automatically opened based on the temperature. This is to take into account that the ambient temperature will change. When the temperature is relatively high and cooling by heat exchange of the air cannot meet the actual requirements, the spray water will be automatically turned on to assist cooling, and the water will evaporate to absorb heat to cool down. ； If the ambient temperature is relatively low, the cooling effect can be fully achieved without turning on the spray, realizing automatic switching, which not only ensures water saving, but also ensures cooling efficiency.
