How to choose the industrial chiller that suits you best? In fact, it is very simple. There is a selection formula:
Refrigeration capacity = chilled water flow rate * 4.187 * temperature difference * coefficient
1. Chilled water flow refers to the cold water flow required when the machine is working, and the unit needs to be converted into liters/second;
2. The temperature difference refers to the temperature difference between the inlet and outlet water of the machine;
3. 4.187 is quantitative (specific heat capacity of water);
4. When choosing an air-cooled chiller, you need to multiply by a factor of 1.3, and when choosing a water-cooled chiller, you need to multiply by a factor of 1.1.
5. Select the corresponding machine model based on the calculated cooling capacity.
It is generally customary to use P to calculate the size of a chiller, but the most important thing is to know the rated cooling capacity. If the general air-cooled one is 9.07KW, choose a 3P machine. And so on. Therefore, the most important thing when selecting an industrial chiller is to find the rated cooling capacity.
