Automotive Air Conditioning Trainer | PolarX - 544
Product Overview
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.

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.
