2. A dual flow air control method for an ECM motor, comprising:
generating a dehumidification control signal G2;
generating a fan control signal G;
generating an auxiliary heat source control signal W; and
wherein the auxiliary heat source control signal W is sent to one gear of the ECM motor; and
the fan control signal G is sent to one gear of the ECM motor; and
the dehumidification control signal G2 is sent to one gear lower than the fan control signal G of the ECM motor; and
sending the dehumidification control signal G2 when an indoor real-time temperature T is at T0+ΔT or less, where ΔT is a temperature threshold and T0 is an indoor cooling target temperature during cooling; and
sending the fan control signal G when the indoor real-time temperature T is greater than T0+ΔT.
