The invention discloses an air conditioning system of an electric automobile and a refrigerating and heating control method of the air conditioning system. The air conditioning system comprises a compressor, a first heat exchanger, a first four-way valve, a throttling device, a second heat exchanger, a third heat exchanger and a second four-way valve. The compressor communicates with the first heat exchanger. The first heat exchanger communicates with a first connector of the first four-way valve. A second connector of the first four-way valve communicates with the third heat exchanger, a third connector of the first four-way valve communicates with a third connector of the second four-way valve, and a fourth connector of the first four-way valve communicates with an inlet of the throttling device. The throttling device is communicated with the second heat exchanger; the second heat exchanger is communicated with a second interface of the second four-way valve; the third heat exchanger is communicated with a fourth interface of the second four-way valve; a first interface of the second four-way valve is communicated with the compressor; the air conditioner further comprises an adjustable air inlet grille and a switching device. The problem that energy consumption is too high in the heating process of an air conditioning system of an existing electric vehicle is solved.
