Calculation of refrigeration capacity for refrigerators
Thread Content
The cooling capacity of the chiller is 1200 KW, with R22 as the refrigerant. The inlet temperature of the chilled water is 35°C, and the outlet temperature is 25°C. How can the flow rate of the chilled water through the chiller be calculated?
1200/4.18/（35-25）=28.7L/S=103.3m3/h, more or less
A temperature difference of 10 degrees is a bit large; generally, the supply water temperature for chillers is 7℃
kw=kj/s·cm△T; this gives the mass, not the volume
