INTRODUCTION
Automobile air conditioning systems are used to cool the air in the interior of the vehicle. They work, in most cases, according to the
recirculating air principle, sucking the air to be cooled from the inside itself.
The objective of the automobile air conditioning trainer designed by EDIBON is to introduce the student into the complex world of the air
conditioning systems, as well as studying and determining the optimum parameters for the operation of the unit concerning the basic
functions of an automobile.
GENERAL DESCRIPTION
All the elements of the TAAU unit are typical elements used in the automotive industry.
The air conditioning unit is basically composed of a motor that drives a compressor via a belt, simulating the automobile engine.
The speed of the motor and, therefore, the speed of the compressor, is regulated through a frequency converter to simulate the drive via
the engine of the vehicle.
The air supplied by the fans enters the cooling system through the condenser to undergo a cooling cycle along that system.
The unit has been designed to study not only the air conditions change but also cooling circuit, by strategically placing temperature and
pressure sensors and flow meters, which enable us to study the cooling cycle.
SPECIFICATIONS
Bench-top unit.
Anodized aluminum structure and panels in painted steel. Main metallic elements in stainless steel.
Diagram in the front panel with similar distribution to the elements in the real unit.
A condenser (radiator).
An evaporator.
Two cooling fans.
A filter.
Electrical motor (to simulate the vehicle combustion engine).
Frequency converter to adjust the number of revolutions of the motor between 300-1500 r.p.m.
Motor speed measurement.
A variable area compressor.
An expansion valve.
A storage tank.
A compartment made of PMMA, with ventilation windows.
A safety pressure switch that switches off the compressor at 14 bars.
Six “J” type temperature sensors.
A low pressure manometer for the coolant to measure the pressure before the compressor.
A high pressure manometer for the coolant to measure the pressure after the compressor and before the condenser.
A high pressure manometer for the coolant to measure the pressure after the condenser.
Flow meter for the coolant, range: 5-60 l./h.
This unit uses R134a coolant (CFC free).
