The invention discloses a new energy vehicle air conditioner cold and heat circulation system and a circulation method thereof. The circulation system comprises a storage tank, a supercharger, a first air energy main machine, a second air energy main machine, a secondary refrigerant heat exchanger and a battery bin heat exchanger. An outlet of the storage tank is connected with an inlet of a battery bin heat exchanger installed in a battery bin through a pipeline, and an outlet of the battery bin heat exchanger is connected with a first port of a first air energy main machine and a first port of a second air energy main machine. A second port of the first air energy main machine and a second port of the second air energy main machine are connected with the inlet end of the supercharger through pipelines. The outlet end of the supercharger is connected with the storage tank, the secondary refrigerant heat exchanger and the first air energy main machine through pipelines. The secondary refrigerant heat exchanger is connected with an inlet of the battery bin heat exchanger. The air is heated or cooled by using the enthalpy change value of the enthalpy change of the refrigerant in the circulation process, the air is not required to be refrigerated and heated after being exchanged by a secondary system of water, and the energy consumption is low.
