How to choose the most suitable Dongguan water chiller for daily industrial production? Actually, there is a direct and simple selection formula:
Refrigeration capacity=chilled water flow * 4.187 * temperature difference * coefficient
1. The chilled water flow refers to the cold water flow required for the operation of the machine, and the unit needs to be converted into liters/second;
2. 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 selecting an air-cooled water chiller, multiply by a factor of 1.3, and when selecting a water cooled water chiller, multiply by a factor of 1.1.
5. Select the corresponding machine model based on the calculated cooling capacity.
Generally, it is customary to calculate the size of the Dongguan water chiller using P, but the most important thing is to know the customized cooling capacity. If the air cooled version is 9.07KW, choose a 3HP machine, and so on. Therefore, the most important thing in selecting Dongguan water chillers is to calculate the customized cooling capacity.
