The invention discloses an electric automobile heat pump air conditioning system by adopting an electric compressor. The system comprises an electric compressor connected with a power battery, the output end of the electric compressor is connected with one port of a two-position three-way electromagnetic valve through a pipeline; two ports of the two-position three-way electromagnetic valve are sequentially connected with a first heat exchanger, an expansion throttle pipe and a second heat exchanger through pipelines; the second heat exchanger is connected with the first normally-closed electromagnetic valve; a pipeline between the second heat exchanger and the first normally-closed electromagnetic valve communicate with three ports of the two-position three-way electromagnetic valve; thefirst normally-closed electromagnetic valve is connected with the second normally-closed electromagnetic valve, a pipeline between the first normally-closed electromagnetic valve and the second normally-closed electromagnetic valve communicates with the input end of the electric compressor, and the second normally-closed electromagnetic valve communicates with a connecting pipeline between the second port of the two-position three-way electromagnetic valve and the first heat exchanger through a pipeline. One of the second port and the third port of the two-position three-way electromagnetic valve and the first normally-closed electromagnetic valve and the second normally-closed electromagnetic valve is selected to be opened to form an air conditioner refrigerating system and an air conditioner heating system.
