1000 cubic meters per hour, which needs to be condensed into water. What size, in terms of area, should the condenser be? ? ? How to calculate
Is this gas water vapor? Under what conditions does it condense? It’s impossible to calculate without the specific data. Also, what structural format would you like to choose?
Saturated water vapor, 4Pa
This is actually quite simple; the steps are as follows. I won’t do the actual calculations for you: 1. Determine the total heat exchange amount based on the volume of gas and the latent heat of water vapor； 2. If it is a shell-and-tube structure, consult the \"Heat Exchanger Design Manual\" to calculate the heat transfer film coefficient for steam condensation outside the tubes; then, using the correlation equations for forced convection with regard to the cooling medium inside the tubes (which may be water), calculate the heat transfer coefficient inside the tubes, and subsequently determine the overall heat transfer coefficient ； 3. Calculate the logarithmic temperature difference: ((T0-T2)-(T0-T1))/ln((T0-T2)/(T0-T1)), where T0 is the saturation temperature of steam ； T1 — Cold medium inlet temperature ； T2 – Outlet temperature of the cold medium. 4. The heat exchange area can be calculated using the parameters mentioned above
