The invention provides an integrated electric air conditioning system for a hybrid electric vehicle. The system can realize free switching of multiple working modes such as independent refrigeration of an engine compressor, independent refrigeration of an electric compressor, simultaneous refrigeration of an engine and the electric compressor and the like by controlling different electromagnetic valves. The system comprises an engine compressor, a cab loop heat exchanger, an original vehicle condenser, a first thermostatic expansion valve, a battery and an expansion water tank. The medium output end of the cab loop heat exchanger is connected into the medium input end of the engine compressor through a return pipeline. The medium output end of the engine compressor is connected to the medium input end of the original vehicle condenser, and the medium output end of the original vehicle condenser is connected to the first thermostatic expansion valve of the medium input port of the cab loop heat exchanger. The system further comprises an integrated unit, and the integrated unit specifically comprises an electric compressor, a condenser, a heat exchanger, a second thermostatic expansion valve, an electronic water pump, an electromagnetic valve A, an electromagnetic valve B and an electromagnetic valve C.
