The Automobile Air Conditioning Unit, "TAAU", consists, basically, of a compressor driven through a belt by a motor that simulates the engine of a car. The number of revolutions of the engine and, therefore, the compressor, can be adjusted with a variable frequency drive.
The air supplied by the fans enters the cooling system through the condenser to undergo a refrigeration cycle through that system.
There is also an evaporator with fan, expansion valve, filter and storage tank.
Apart from the air conditions change, the unit has been designed to study the refrigeration circuit too by strategically locating temperature sensors, monometers and flowmeters, which enable the user to study the refrigeration cycle.
All the components of the system are typical elements employed in the car industry and are directed to the practice.
