When selecting and designing closed-loop cooling towers, factors such as the local wet-bulb temperature and other environmental and meteorological conditions are generally taken into account, as these factors have a significant impact on the cooling efficiency and safe operation of the cooling towers. There are significant differences in climate and temperature between the north and south of our country; therefore, different measures need to be taken when using closed-type cooling towers in various regions. Aikemike will talk to everyone about the impact of regional conditions on the cooling efficiency of closed-loop cooling towers. 1. The relationship between cooling efficiency and local climate temperature: Cooling towers are evaporative air cooling devices; the basic condition for cooling is the evaporation of water, which enables heat dissipation and temperature reduction. Evaporation of water is closely related to the ambient wet-bulb temperature. Generally, the lower the wet-bulb temperature, the greater the evaporation capacity, and the higher the cooling efficiency of the cooling tower. Therefore, in the cold and dry climate of the north, cooling towers achieve the highest efficiency, while in the hot and humid climate of the south, their efficiency is the lowest. Therefore, in the south, cooling towers often need to be of a larger size, while in the north, smaller tower sizes can achieve a high cooling capacity. In other words, both temperature and humidity affect the cooling efficiency of closed-loop cooling towers. 2. Regarding the issue of freezing, regional differences not only affect the cooling efficiency of cooling towers; the specific impacts on these towers also require manufacturers to take into account regional climate variations during design. We are aware that northern regions often experience low temperatures in winter, with temperatures frequently dropping below minus 10 degrees or even lower. In such climates, if a user’s cooling system shuts down unexpectedly and there is no time to drain the circulating water from the system, the consequences can be severe. In most cases, the cooling coils in closed-loop cooling towers freeze and burst, resulting in equipment damage; in severe cases, all such cooling towers become unusable, forcing users to suspend operations for extended periods and causing immeasurable losses to them. Fortunately, the detachable plate-type closed towers designed and manufactured by Shenzhen Aikemike Technology Co., Ltd. have the ability to resist freezing, and do not cause pipe rupture once frozen, thereby eliminating the risk of freezing problems in winter for users. Therefore, when choosing a closed-type cooling tower, users should opt for equipment that has no potential hazards. 3. Regarding dry air cooling, we know that the heat dissipation of cooling towers is closely related to the ambient temperature, especially in the case of closed-type cooling towers; the lower the ambient temperature, the better. The higher the cooling efficiency, the more users tend to prefer using dry air cooling when the ambient temperature drops to a certain level, rather than using spray water, as this helps to avoid significant losses of evaporated water. Indeed, since dry air cooling does not require the use of spray water, an evaporation loss of nearly 1% per hour can be avoided. For large industrial users with circulation water volumes in the tens of thousands of tons, the evaporation rate can reach hundreds of tons per hour, resulting in losses of over 20,000 tons of water per day. If such losses could be eliminated throughout the winter in the northern regions, millions of dollars could be saved over three months each year. However, conventional closed-type cooling towers have almost no cooling effect when there is no spray water, which is determined by their cooler structure; the convective heat exchange between the coil cooler and the air is virtually ineffective. A completely new type of plate-type closed tower, developed by Ecomic, achieves heat exchange performance that is on par with that of wet-cold closed towers even in cold and dry winter conditions. This allows for water savings for users during winter without compromising their cooling needs. In fact, the Aikemik plate-type closed tower enables dry air cooling not only in winter, but also during the spring and autumn when temperatures are low (when the ambient temperature is below 15°C), thus saving water and energy. In the design of the Aikemic closed-loop cooling tower, the spraying system is activated automatically based on temperature. This is to account for fluctuations in ambient temperature; when the temperature is high and cooling through air heat exchange is not sufficient to meet the requirements, the spray water is automatically activated to assist in cooling, with the water evaporating to absorb heat and thereby reduce the temperature ； If the ambient temperature is low, it is possible to achieve cooling effects without turning on the spray system, enabling automatic switching that ensures both water conservation and efficient cooling performance.
