In the process of using industrial chiller for production, when cooling equipment and materials, it is necessary to consider a technical parameter - cooling capacity. So how to calculate the cooling capacity of industrial chiller? The following by Danes chiller to take you to understand. Industrial chillers need to ensure that they have sufficient cooling capacity to achieve the effect of controlling the temperature to the required temperature within a certain period of time. To think simply, the choice of large cooling capacity of the chiller can ensure sufficient cooling capacity. However, the larger the cooling capacity of the chiller, the higher the unit investment, the later use of energy consumption will also increase. Therefore, if enterprises want to choose the right industrial chiller, the key is to calculate the cooling capacity reasonably and scientifically.

The following formula can be used to calculate the cooling capacity of industrial chiller:

Cooling capacity = water flow or production (converted to L) × temperature difference ÷860 = cooling capacity (kw)

- Water flow rate refers to the water flow required by the machine during operation;

- The temperature difference refers to the temperature difference between the machine and the water.

Air-cooled chiller adopts air cooling method, without cooling tower, cooling water pump, nor special room, can be installed on the roof and outdoor. Air cooled industrial chiller adopts scroll compressor, the main refrigeration components are well-known brands at home and abroad, excellent performance, reliable work.

The cooling capacity of the water-cooled chiller is large, but it needs to be equipped with a cooling tower to achieve a good cooling effect. The cooling tower is a refrigeration device, which cools the water, consumes the heat of the unit itself through the cooling water, and the frozen water is cooled through the evaporator of the unit, and the water source provided by the cooling tower is mainly from the heat exchange in the condenser.

In general, like household air conditioners, industrial chillers generally calculate the cooling capacity in P(HP, the number of compressors). For example, the cooling capacity of 90KW is required, and the cooling capacity of 1P≈2.85kW /1.39kW power is selected. 32HP water-cooled industrial chiller can basically meet the requirements, and the chiller is equal to or greater than the required number as the standard. In the selection of industrial chiller, the most important problem is to calculate the demand for cooling capacity, master the calculation formula of cooling capacity, and basically solve the problem of how to choose the right industrial chiller.
