General Description

The Computer Controlled Thermal Conductivity of Liquids and Gases Unit, "TCLGC", has been designed to allow the students to appreciate and understand the heat transfer process through any gas or liquid locked in a solid.

By the realization of the practices the student can determine the thermal conductivity of any gas or compatible liquid with the construction materials.

The Computer Controlled Thermal Conductivity of Liquids and Gases Unit "TCLGC" consists of an aluminum cylinder, that forms the body of the unit, which has inside a variable power heating element and temperature sensors, one of them inside the own heating element. It also has a brass jacket that contains the test fluid and the refrigeration water.

The fluid, whose thermal conductivity is to be determined, fills the small distance of radial security between the body of heated aluminum and a jacket with cooled water. This space is small enough to avoid the natural convection of the fluid.

The aluminum body and the water jacket are concentric thanks to two "o" ring joints which seal the distance of security, and which allow

easily and quick dismantling for cleaning.

The unit incorporates a water regulation valve, which allows the flow of water to be varied, a water flow sensor, and temperature sensors at the water inlet and outlet.

The connection and disconnection of the sensors have been made to be easy and comfortable.

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

  1. Obtaining of the curve of thermal conductivity of the air.
  2. Thermal conductivity in vacuum.
  3. Water thermal conductivity determination.
  4. Thermal conductivity determination of a mineral oil.
  5. Sensors calibration

MORE PRACTICAL EXERCISES TO BE DONE WITH THE UNIT

Additional practical possibilities:

  1. Dry air thermal conductivity under atmospheric pressure.

Other possibilities to be done with this Unit:

  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical and electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the TCLGC unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the TCLGC unit process.
  9. By using PLC-PI additional 19 more exercises can be done.
  10. Several other exercises can be done and designed by the user.
