The invention discloses an electric automobile heat management loop system and a control method thereof. The system comprises a compressor, an air conditioning box assembly, an external heat exchanger and an integrated module. The air conditioning box assembly comprises an in-vehicle evaporator and an in-vehicle condenser, and the integrated module comprises a plurality of refrigerant connectors. The in-vehicle condenser comprises two refrigerant inlets and a refrigerant outlet. The integrated module is connected with the compressor, the exterior heat exchanger and the air conditioner box assembly. The integrated module is connected with the in-vehicle evaporator through the first refrigerant connector, connected with a refrigerant outlet of the in-vehicle condenser through the second refrigerant connector, connected with the first end of the out-vehicle heat exchanger through the third refrigerant connector, connected with the second end of the out-vehicle heat exchanger through the fourth refrigerant connector and connected with an inlet of the compressor through the fifth refrigerant connector. An outlet of the compressor is connected with the second end of the out-vehicle heat exchanger and the in-vehicle condenser, and the in-vehicle evaporator is connected with a fifth refrigerant connector of the integrated module and an inlet of the compressor. Efficient thermal management of the whole vehicle is achieved.
