Design of air coolers
Thread Content
There is currently a air cooler with a single tube side consisting of light oil + water (gas). The inlet temperature is 120 degrees, the outlet temperature is 45 degrees, the flow rate is 9000 KG/H, and the ratio of oil to water is 8:1. Two motors of 18.5 KW each are used, the air volume required is 160,000 m³/h, and the total pressure is 245 Pa. The area of each unit I selected is 250 square meters, with a fin ratio of 10. Is it feasible to use a single tube side in this case? Urgent! Could you guys help me do the calculation?
Choose single-pass mode! An air-cooled condenser, right? For such a temperature range, an evaporative air cooler is the appropriate choice; shouldn’t an air-cooled one be used instead? This post was last edited by ZLF60137 on 2009-3-30 16:20.]
Could the guy upstairs please explain why a single-threaded approach is acceptable?
After ensuring the heat exchange area, using a single-pass design can effectively reduce the resistance in the tube side
What if the flow rate is too low, affecting heat transfer?
Where did your 250 come from? Isn’t it calculated by first assuming the structure and flow velocity?
