Automotive Air Conditioning Trainer | PolarX – 544
The Automotive Air Conditioning Trainer PolarX – 544 replicates a vehicle’s air conditioning system, using a compressor, condenser, filter/drier, expansion valve, and evaporator to produce cold air. This Automotive Air Conditioning Trainer runs on a standard automotive 12VDC supply, with compressor drive via V-belt, magnetic coupling, and a variable-speed motor controlled by a frequency converter. An axial piston compressor (greater than 3HP) delivers approx. 3kW refrigeration capacity at 3000RPM, with 4 Type-k temperature sensors and optional simulation of 8 system faults. Optional LABVIEW-based DAQ software supports automated data measurement.
The Automotive Air Conditioning Trainer PolarX – 544 replicates a vehicle’s air conditioning system used to cool the car’s interior. This Automotive Air Conditioning Trainer operates on the recirculating air principle, aspirating air from the interior and propelling chilled air back into the cabin via fan.
Product Overview A compressor, a condenser with fan, and an evaporator acting as an air cooler with a three-stage fan and expansion valve make up the refrigeration circuit used to produce cold air in this Automotive Air Conditioning Trainer. All system parts reflect common aspects found in automotive technology. For example, the air cooler with the three-stage fan is fitted with the normal air vents seen inside a car, bringing the trainer close to real-world practice.
The trainer runs on a standard automotive 12VDC power supply. The system also includes the ability to lock the ignition. The compressor is driven by an electric motor using a magnetic contact and a V-belt. A frequency converter allows variable adjustment of the motor’s and compressor’s speed, imitating the drive via the vehicle engine.
Pressure, temperature, flow rate, and the compressor’s power consumption are among the significant characteristic factors displayed. Eight connectable faults have been installed specifically (optional). The system is especially effective for teaching motor mechanics. Comprehensive course materials outline the fundamentals and offer a step-by-step walkthrough of the experiments.

Construction and Design
The Automotive Air Conditioning Trainer PolarX – 544 uses a compression refrigeration system consisting of a compressor, condenser, filter/drier, expansion valve, and evaporator. An electric motor with variable speed drives the compressor via V-belt and magnetic coupling. The condenser is fitted with a fan, and the evaporator functions as an air cooler with a three-stage fan. A frequency converter enables variable adjustment of motor and compressor speed to imitate drive via the vehicle engine. The system is switched on via an ignition lock and runs on a 12VDC supply. Eight faults can be simulated via buttons in an optional connectable box.
Software
PolarX – 544 (optional). A DAQ software package, specially designed in National Instruments LABVIEW environment, measures and calculates the results of the apparatus. The software is optional. When the software is used, a set of electronic sensors is included. The software can be run on any Windows environment.
