Compressed air heat transfer； Alcohol heat transfer
Thread Content
How should the heat exchange area be calculated for the following operating conditions? Could some kind person help? 1. Hot side: 0.3 MPa compressed air, 72 m3/h, +40 ~ -12℃ ； Cold side: ethanol at 15 ~ -13°C; hot side: compressed air at 0.3 MPa, flow rate of 72 m3/h, temperature range of +40 ~ -3℃ ； Cold side: ethanol –15 to –13°C 3; hot side: alcohol, 25 m3/h, –25 to –30℃ ； Cold side: Freon evaporation, -35 ℃
It can be calculated, but I don’t know what type of heat exchanger you plan to use to achieve the above goal. Because I am not aware of your requirements regarding the manufacturing process and installation space. pkang18@hotmail.com
Reply to 2# paulkang: A tubular heat exchanger will do. I don’t know what value to use for the overall heat transfer coefficient; what is a typical value for it?
