Title: Interlocked control for car air conditioning plant - has compressor action inhibited when starter motor switched on to avoid overload
Inventor: KUHN HANS-ULRICH
IPC: B60H1/32
Filed: 1976-03-30
Abstract: The air conditioning plant has a first control circuit which switches on the compressor when the temperature rises above a set value. A second control circuit inhibits the compressor action when the starter motor is operated, so that the starter motor is not overloaded, the compressor being driven from the engine. A common switch control is provided for both circuits (8) for a simple layout. The first circuit is provided with a lomiting resistor (9) an d diode (10) to short circuit the circuit when the common switch is moved to the starter motor 'on' position. This provides a failsafe interlock to inhibit the compressor action. The system always protects the starter motor, even when the second circuit fails.
