The Computer Controlled Automobile Air Conditioning Unit, consists, basically, of a compressor driven through a belt by a motor that simulates the engine of a car.
Technical Specifications
ATENG 12716 — Computer Controlled Automobile Air Conditioning Unit
(for main items)
With this unit there are several options and possibilities:
Main items: 1, 2, 3, 4, 5 and 6.
Optional items: 7, 8, 9, 10 and 11.
Let us describe first the main items (1 to 6):
1TAAUC. Unit:
Bench-top unit.
Anodized aluminum frame and panels made of painted
steel.
Main metallic elements made of stainless steel.
Diagram in the front panel with distribution of the
elements similar to the real one.
Includes:
Condenser (radiator).
Evaporator.
Two computer controlled refrigeration fans.
Filter.
Computer controlled electric motor (to simulate the
car’s engine).
Variable frequency drive to adjust the number of
revolutions of the motor between 300 and 1500 rpm.
Computer controlled variable area compressor.
Expansion valve.
Storage tank.
Unit: ATENG 12716
Compartment made of methacrylate with ventilation windows.
Safety pressure switch that stops the compressor at 14 bars.
Instrumentation:
Six “J” type temperature sensors.
Low pressure manometer for the coolant to measure the pressure before the compressor.
High pressure manometer for the coolant to measure the pressure after the compressor.
High pressure manometer for the coolant to measure the pressure after the condenser.
Two pressure sensors, one for the high pressure of the coolant, range: 0 – 25 bar, and another for
the low pressure of the coolant, range: 0 – 10 bar.
Flow sensor of the coolant, range: 5 – 60 l/h.
Psychrometric chart and enthalpy diagram of R-513a.
This unit has been designed for the use with the refrigerant R-513a, CFC-free, environmental friendly.
The complete unit includes as well:
Advanced Real-Time SCADA.
Open Control + Multicontrol + Real-Time Control.
Specialized Control Software based on LabVIEW.
National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
Calibration exercises, which are included, teach the user how to calibrate a sensor and the
importance of checking the accuracy of the sensors before taking measurements.
Projector and/or electronic whiteboard compatibility allows the unit to be explained and
demonstrated to an entire class at one time.
Capable of doing applied research, real industrial simulation, training courses, etc.
Remote operation and control by the user and remote control for technical support,
are always included.
Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
Designed and manufactured under several quality standards.
Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
calculations, etc. Apart from monitoring user's knowledge and progress reached.
This unit has been designed for future expansion and integration. A common expansion is
the Scada-Net (ESN) System which enables multiple students to simultaneously
operate many units in a network.
