TRD2PC Computer Controlled Two Doors Domestic Refrigeration Unit
The objective of the Computer Controlled Two Doors Domestic Refrigeration Unit, "TRD2PC", is to introduce the student into the complex world of refrigeration systems through a common domestic appliance.
The main element of the Computer Controlled Two Doors Domestic Refrigeration Unit, "TRD2PC", is a combifridge freezer with transparent panels to observe all the elements of a refrigeration cycle: compressor, filter,evaporator, condenser, etc.
Throughout the refrigeration circuit, temperature sensors and pressure sensors are arranged at key points ofthe circuit.
The fridge has an upper door for a refrigerator and a lower door for the freezer. There are mobile temperaturesensors in both compartments.
It has a thermostat to adjust the cooling temperature and a defrost heating element to prevent the evaporatorfrom freezing.
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 Acquisitionand Data Management Software Packages, for controlling the process and all parameters involved in theprocess.
Exercises and guided practices
GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL
- Study of the operating principle of a combi fridge freezer.
- Familiarization with the main components of a refrigerator.
- Study of the food position influence in the refrigerator.
- Thermostat setting.
MORE PRACTICAL EXERCISES TO BE DONE WITH THE UNIT
- Many students view results simultaneously.To view all results in real time in the classroom by means of aprojector or an electronic whiteboard.
- 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.
- The Computer Control System with SCADA allows a realindustrial simulation.
- This unit is totally safe as uses mechanical, electrical/electronic,and software safety devices.
- This unit can be used for doing applied research.
- This unit can be used for giving training courses to Industrieseven to other Technical Education Institutions.
- Control of the TRD2PC unit process through the control interfacebox without the computer.
- Visualization of all the sensors values used in the TRD2PC unitprocess.
- Several other exercises can be done and designed by the user.
