How to choose the right chiller?

How to choose the right chiller? In fact, it is very simple. There is a model selection formula: refrigerating capacity = chilled water flow *4.187* temperature difference * coefficient.

1. Chilled water flow refers to the cold water flow required by the machine during operation, and the unit shall be converted into liters / second.

2. Temperature difference refers to the temperature difference between the inlet and outlet water of the machine, and the unit is ℃.

3. 4.187 is the quantity (specific heat capacity of water), and the unit is kj/kg ℃。

4. When selecting air-cooled chiller, multiply the safety factor by 1.3, and when selecting water-cooled chiller, multiply the safety factor by 1.1.

5. Select the corresponding machine model according to the calculated refrigerating capacity.

6. The unit of calculated refrigerating capacity is kj h,1kw=3600kj. H generally, it is used to calculate the size of the chiller with P, but the main thing is to know the customized cooling capacity. Generally, if the air cooling is 2.5kW, the 1p machine is used And so on. Therefore, it is important to calculate the customized cooling capacity for the selection of industrial chillers.

Air cooled chillers and water-cooled chillers are the two most common industrial chillers. Some people think that air-cooled chillers are good, while others think that water-cooled chillers are good. How to choose them also needs to be considered in many aspects.
