The invention mainly aims to provide a fresh air device and an indoor unit of an air conditioner. The fresh air device comprises a fresh air housing, a heat exchange core and an auxiliary inlet air heating device; a fresh air channel and a polluted air channel are formed in the fresh air housing; a fresh air inlet, a fresh air outlet, a polluted air inlet and a polluted air outlet are formed in the fresh air housing; the fresh air inlet and the fresh air outlet communicate with the fresh air channel; the polluted air inlet and the polluted air outlet communicate with the polluted air channel;the heat exchange core is arranged in the fresh air housing; the heat exchange core communicates with the fresh air channel and the polluted air channel, so that fresh air in the fresh air channel performs heat exchange with polluted air in the polluted air channel in the heat exchange core; and the auxiliary inlet air heating device is arranged in the fresh air channel and is positioned between the heat exchange core and the fresh air inlet, so that the fresh air enters the fresh air channel from the fresh air inlet, and flows in the heat exchange core after being heated by the auxiliary inlet air heating device. The fresh air device, provided by the invention, solves the problem that in the prior art, a way of introducing fresh air in a room causes energy loss in the room.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fresh air device and an air conditioner indoor unit. Background technique [0002] In recent years, due to rapid economic development and accelerated urbanization, air pollution has become increasingly serious. Perennial smog has already occurred in most cities in China. The increase in the concentration of PM2.5 directly leads to the frequent occurrence of haze weather and the substantial increase of toxic and harmful substances in the fog, which has seriously threatened human health. In this case, conventional household comfort air conditioners can no longer meet people's needs, and health, comfort, and environmental protection have become the goals of modern air conditioner development. [0003] For ordinary air conditioners, in order to ensure the air conditioning effect, the air conditioning room must be closed. As a result, the indoor dust, smog, bacteria, viru...
