Abstract
The utility model relates to an electric air conditioning system for a fuel /gas automobile. The system comprises an evaporator assembly, a condenser assembly, a compressor, a throttle component and an electric control assembly, wherein the compressor is an electric compressor which is in electric connection with an engine, a storage battery and a compressor driver, and the engine is driven by an output shaft of an automobile engine in a belt transmission mode. An existing belt wheel type compressor driven by a belt wheel directly through the automobile engine is replaced by the electric compressor so that the whole air conditioning system operates. The system has the advantages that a fuel /gas engine does not directly drive the compressor, and the compressor is driven by electricity due to the fact that the engine converts kinetic energy into the electricity. Due to storable property of the electricity, the electric compressor can still operate even if the engine stops working when an automobile is stopped. Therefore, the whole air conditioning system can be used under a parking state, and fuel/gas is saved.
