Electrical Faults in Air- Conditioning Systems Model RAC 082
Identifying electrical faults in air conditioning systems requires comprehensive knowledge This knowledge includes the design and operation of the individual electrical components as well as the reading of circuit diagrams. ET 170 helps to acquire this knowledge. Sci-tech Electrical Faults in Air-Conditioning System Model RAC 082 demonstrates the electrical circuit of a simple air conditioning system, consisting mainly of a refrigerant compressor and fan at the air cooler. The control circuits are actually present. Compressor and fan motor are simulated.
Item Description
Features
* Simulation of a simple air conditioning system with compressor, fan and thermostat
* Investigation of key electrical components from air conditioning technology
* Simulation of 15 faults
The compressor is controlled via a thermostat. Via a ballast the fan motor speed can be switched in two stages. The start of the compressor motor takes place via a start-up relay and start-up capacitor. Typical protection devices, such as circuit breaker, complete the electrical circuit. The operating state of the simulated components compressor and fan is indicated via lamps in the circuit diagram on the front panel. The simulation of 15 different faults, such as coil fracture in the motor or faulty switching contact, is possible. For fault indication, voltages and resistances are checked at the lab jacks with the multimeter. The depiction of the circuit diagram on the front panel facilitates the allocation of the measuring points. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
