Method for vehicle air conditioning, comprises control of compressor motor starting speeds by comparing motor current with first and second current thresholds derived from test data

摘要

The air conditioning system uses a compressor (1) and heat exchangers (3,4) to supply air to the windscreen and cabin (16b,16c). Test data is used to produce first and second thresholds. If the compressor motor current is greater than the first threshold compressor speed is limited. The speed limitation is continued if the compressor motor current is greater than the second threshold An Independent claim is also included for: A system which uses the method of compressor motor speed control
