Common calculation methods of water-cooled air conditioning with Dongguan water chiller
1. Calculation of water-cooled air conditioner and water chiller
Q=air volume × Temperature difference × specific heat × safety factor
Q/is the cooling capacity calculated by the chiller
Air volume/drying air volume of honeycomb machine
Temperature difference
Specific heat/plastic is generally 0.24 according to different plastic PET
Safety factor/generally 1.2-1.8
Example: air volume 1300m3 × The temperature difference is 120 degrees (the return air temperature drops from 160 degrees to 40 degrees) × Specific heat 0.24 × Safety factor 1.2
one thousand and three hundred × one hundred and twenty × zero point two four × 1.2=44928kcal/h=52kw refrigerating capacity Yo 20hp water chiller
2. Cooling capacity calculation of Dongguan chiller
Weight of water/liter × Temperature difference × Time=refrigerating capacity kcal/h
For example, 100 liters of water in the water tank × 10 ° temperature difference × Time 5 minutes=1200 kcal/h=13.9 kw
3. Water flow × Temperature difference=cooling capacity set as 5 degrees
For example, the flow is 4820 × Temperature difference 5 degrees=24100kcal/h=28kw
