How to calculate the refrigerating capacity of the cold water machine

by:CBFI     2020-09-26
Summer will come, little to the laboratories of scientific research, the big to the enterprise manufacturing all face the choice of the cold water machine problem. How is the cold water machine selection problem. Pause type is actually not difficult also, cold water first according to their own situation, choose air-cooled industrial ice machine or screw chillers; Then in the need to supply the refrigerating capacity by calculation in the corresponding manufacturers cold water model number list can be selected according to the refrigerating capacity corresponding applicable models.

the capacity calculation formula: frozen water refrigerating capacity = & times; 4. 187× Temperature & times; Coefficient of

1, freezing water flow refers to the machine's work when the cold water flow, unit need to conversion to liters/s;

2 refers to the machine, the temperature difference between in and out of the water temperature difference;

3、4. 187 for quantitative ( The heat capacity of the water) ;

4, choose cold water unit need to be air cooled by coefficient of 1. 3, choose water cooled industrial ice machine by coefficient of 1. 1;

5, select the machine according to the refrigerating capacity of the calculation model.

general confidential with much of the cold water use P to calculate, but the most important is to know the rated refrigerating capacity, generally air cooled 9. 7 kw way choice with 3 p machine, and so on, so the selection of industrial cold water machine the most important thing is to find the rated refrigerating capacity.
