TIFCC Computer Controlled Cross Flow Heat Exchanger
The Computer Controlled Cross Flow Heat Exchanger, "TIFCC", consists of a rectangular wind tunnel made of stainless steel, resistant to corrosion. It has a bell-shaped inlet and a central opening arranged longitudinally with two supporting elements made of stainless steel to retain the plates with the different exchangers.
The Computer Controlled Cross Flow Heat Exchanger (TIFCC) basically consists of a rectangular wind tunnel made of stainless steel, resistant to corrosion. It has a bell-shaped inlet and a central opening arranged longitudinally with two supporting elements made of stainless steel to retain the plates with the different exchangers.
The tunnel is installed over the inlet of a powerful centrifugal fan and connected to it by an elastic coupling flange. This fan aspirates air from the tunnel and expels it outside, making air flow along the tunnel. There is a variable speed drive to control the air flow through the tunnel with the fan control through the computer.
The TIFCC unit includes two types of exchangers: a pinned (multi-tube) exchanger and a single tube exchanger, where the heating element is lodged, which is controlled through the computer.
To perform all the practical exercises the unit has two temperature sensors to measure the air temperature in the tunnel, before and after passing through the heat exchanger, a control temperature sensor lodged in the heating element and a flow sensor that allows the user to determine the air flow along the tunnel.
Available two optional exchangers: Local Heat Transfer Exchanger (TIFCC/A) and Finned Tube Exchanger (TIFCC/F).
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
Exercises and guided practices
GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL
- Investigation of convective processes.
- Determination of heat transfer in a single tube exchanger.
- Determination of heat transfer in a pinned (multi-tube) exchanger.
- Determination of the average heat transfer in a pinned (multitube) exchanger.
