The invention discloses a backheating method and a backheating structure for a heat pump air conditioner, which can improve the performance of the air conditioner. The backheating structure comprises heat exchangers A and B, a compressor, and a throttling element connected between the heat exchangers A and B, wherein the heat exchanger B is connected with the compressor by an air suction pipe of the compressor; and a higher-temperature coolant in the throttling element performs heat exchange with a lower-temperature coolant in the air suction pipe of the compressor.
