How to choose a suitable cooling tower for a water-cooled chiller

Aug 31, 2021

In many special use environments, companies need to apply water-cooled chillers. Since water-cooled chillers need the help of cooling towers during operation, they need to follow the instructions introduced by the chiller manufacturer after purchasing water-cooled chillers. Relevant experience, complete the normal operation of water-cooled chillers, and ensure high performance of water-cooled chillers.


How to choose to buy a cooling tower?

In the actual use environment, there are different types of cooling water towers. Simply distinguished from the shape, domestic cooling water towers are divided into two types: rectangular and circular. As for the specific functions, rectangular and circular cooling towers have similar functions, and there is no According to the introduction of the refrigerating machine factory manufacturer, the circular cooling tower can adapt to more use environments and achieve the purpose of improving the working efficiency of water-cooled chillers.


Determine the model and specific specifications of the cooling tower


Different water-cooled chillers need to be matched with different specifications of cooling towers. In the selection process, it is necessary to select suitable cooling tower equipment according to the specific data of the cooling water flow, and at the same time ensure that the water flow is in a more suitable state to ensure water cooling. According to the requirements of the refrigeration plant, the water flow rate of the cooling tower should not be higher than 20%. As long as it meets the specific value range, it can meet the needs of water-cooled chillers.


Specifications of cooling tower


In the process of purchasing a cooling tower, as to which specifications to choose, you need to complete the entire selection process according to actual needs, such as the specific operating power of the water-cooled chiller, and the amount of water inflow and discharge, combined with specific data to select the appropriate cooling tower product. At the same time, it should be noted that normal water-cooled chillers need to be equipped with a cooling water tower. The number of cooling water towers to be purchased needs to be determined according to the actual number of water-cooled chillers, and the principle of one-to-one purchase is realized, so as to meet the normal conditions of water-cooled chillers. Operational requirements.


For the introduction of cooling water tower selection techniques, users can realize that water-cooled chillers can meet daily production needs only when they cooperate with cooling water towers. The lack of any equipment has a great impact on cooling water towers. Therefore, choosing high-quality cooling water towers will improve The specific performance of water-cooled chillers plays a vital role.

Generally, when we choose a cooling tower, there is a commonly used formula:

Cooling water flow = host refrigeration capacity (KW) * 1.2 * 1.25 * 861/5000 (m3/h)

Cooling water volume = host condenser load (kcal/h) * 1.2/5000 (m3/h)

Cooling water volume = host condenser heat load (m3/h) * 1.2 (m3/h)

Cooling water volume = host cooling capacity (RT) * 0.8 (m3/h)

Cooling water volume = heat load of main engine evaporator (kcal/h) * 1.5 * 1.25/5000 (m3/h)

Cooling water volume = heat load of main engine evaporator (m3/h) * 1.2 * 1.25 (m3/h)

Cooling water volume = host evaporator heat load (RT) * 1.2 * 1.25 * 3024/5000 (m3/h)

Note: 1.2 above is the selection margin, 1.25 is the condenser load factor
