Heat exchangers
The design of this unit allows the study of three industrial exchangers
with identical surfaces: a plate heat exchanger, a glass shell and SS tube
heat exchanger and a glass shell and glass tube heat exchangers.
Two three‐way valves allows the study in co‐current and counter-current
flow in each heat exchanger.
Study the parameters affecting heat transfer
Exchanger materials: glass, stainless steel
Regime: turbulent, laminar
Circulation: co-current, counter-current
Thermal transfer fluid used: hot water, steam
Characterize and compare heat transfers
Thermal balance
Yield
Overall experimental and theoretical heat exchange coefficient K
