Cooling tower cooling technology design requirements - Database & Sql Blog Articles

In cold and severe cold areas, it's essential to implement antifreeze measures to protect the cooling system from damage caused by freezing temperatures. Proper planning and design are crucial to ensure the system operates efficiently under extreme weather conditions. When determining the parameters and equipment specifications for a cooling tower cooling system, several factors should be taken into account: 1. The cooling capacity of the end coil must be sufficient to meet the winter cold load demand, considering the highest calculated water supply temperature and the temperature difference between the supply and return water. It’s recommended to increase the water supply temperature as much as possible to extend the cooling tower's operating time during colder periods. 2. When calculating the maximum cooling tower performance for cold water temperature, temperature difference, and the number of units required in winter, it's important to base these calculations on the cooling load demand, the air conditioning cold water temperature, and the cooling tower's capacity under outdoor winter weather conditions (as provided by the manufacturer or based on relevant data). Other factors like heat exchanger temperature differences should also be considered. 3. For open cooling towers, it's advisable to install a plate heat exchanger, which can allow a heat exchange temperature difference of 1–2°C. In contrast, closed cooling towers can directly supply cooled water without the need for an additional heat exchanger. 4. The specifications and number of circulating pumps used for winter air conditioning and plate heat exchangers should be matched with the specific requirements of the cooling system during cold weather to ensure optimal performance. These guidelines are compiled based on real-world challenges faced by professionals in the field. They are meant for reference only.

Always consult with a qualified engineer or technician when designing or modifying a cooling system.
