Electrical Faults In Full Air Conditioning Systems

Product Description

Electrical Faults in Full Air Conditioning Systems Technical Description of Electrical Faults in Full Air Conditioning Systems 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. Helps to acquire this knowledge. Demonstrates the electrical circuit of a complex full conditioning system with heat pump function. The control circuits are actually present. The components in the load circuits are simulated (e.g. compressor, heater, 4-way reversing valve). The air conditioning system with heat pump function cools in the summer and heats in the winter. During heating operation the defrost timer introduces a hot gas defrosting by briefly switching the 4-way reversing valve. At very low outer temperatures an electrical auxiliary heating is activated during heating operation. With low air humidity the hygrostat activates the humidifying function. Typical protection devices, such as circuit breaker and frost protection monitor, complete the electrical circuit. The operating state of the simulated components is indicated via lamps in the circuit diagram on the front panel.
