In the prior art, an air conditioner is composed of at least a compressor, an outdoor heat exchanger, a throttling device, and an indoor unit evaporator. During refrigeration, the compressor compresses the refrigerant to a high-temperature high-pressure state, the high-temperature high-pressure gas-phase refrigerant is discharged from the compressor and flows into the outdoor heat exchanger, and the refrigerant releases heat in the outdoor heat exchanger to the ambient environment and is condensed into a liquid-phase refrigerant. The high-temperature high-pressure liquid-phase refrigerant flows out of the outdoor heat exchanger and is expanded into a low-pressure liquid-phase refrigerant through the throttling device. The low-pressure liquid-phase refrigerant flows into the indoor heat exchanger to absorb heat in the indoor environment and is evaporated into a gas-phase refrigerant, and the gas-phase refrigerant flows back into the compressor to continue circulating refrigeration. The circulation process of the refrigerant during heating is reverse to that of the refrigerant during cooling. One end of the compressor, where the gas-phase refrigerant is discharged, is provided with a four-way reversing valve to realize switching of refrigerant circulation directions during refrigeration or heating.

The air conditioner comprises an air conditioner indoor unit and an air conditioner outdoor unit, the air conditioner outdoor unit at least comprises a compressor and an outdoor heat exchanger, the air conditioner indoor unit at least comprises an indoor heat exchanger, and the throttling device can be arranged in the air conditioner indoor unit or the air conditioner outdoor unit. During refrigeration, the outdoor heat exchanger is used as a condenser, and the indoor heat exchanger is used as an evaporator; when heating, the outdoor heat exchanger is used as an evaporator, and the indoor heat exchanger is used as a condenser.

Air conditioners in the prior art drive air to flow by circulating indoor air, so that the temperature, the humidity and the like of the air in an indoor environment are adjusted indoors. However, during the use of the air conditioner, the doors and windows are usually closed, and the oxygen content of the air in the indoor environment is reduced and the air becomes dirty for a long time. In order to improve the air in the indoor environment, a fresh air device is needed to be arranged, fresh air is introduced into the room through the fresh air device, so that sufficient oxygen is kept in the room, the content of indoor carbon dioxide is reduced, and the indoor air quality is improved.

Therefore, the indoor unit of the air conditioner has a fresh air mode, fresh air flows into the heat exchange cavity 120 through the fresh air shell 310 and is sent into a room after exchanging heat with the indoor heat exchanger, and therefore the purpose that only fresh air is provided indoors to improve the indoor air quality can be achieved. Optionally, when the fresh air housing 310 is in the avoiding state, it slides to other positions inside the casing 100 to avoid opening the air inlet 110. Therefore, the indoor unit of the air conditioner has an air mixing mode, and indoor air flows into the indoor unit of the air conditioner through the air inlet 110 to exchange heat with the indoor heat exchanger. Meanwhile, outdoor fresh air flows into the heat exchange cavity 120 through the fresh air shell 310 to exchange heat with the indoor heat exchanger, that is, indoor air and outdoor fresh air exchange heat with the indoor heat exchanger and are mixed to be sent into a room, so that the purposes of conveying the indoor air and introducing the fresh air to the room to improve the indoor air quality can be achieved.

By adopting the indoor unit of the air conditioner, through controlling the sliding of the fresh air shell, when the fresh air shell is shielded and closed, the outdoor fresh air and the indoor heat exchanger realize heat exchange and then are sent into the room, or when the fresh air shell is avoided and opened, the outdoor fresh air and the indoor circulating air and the indoor heat exchanger realize heat exchange and then are sent into the room. Therefore, the situation that outdoor fresh air is overheated or overcooled can be avoided, the comfort level of outdoor fresh air supply is improved, and the comfort and experience of users are improved; in addition, the indoor fresh air can be independently sent into the outdoor fresh air to improve the indoor air quality, the outdoor fresh air and the indoor fresh air can be simultaneously conveyed, and the diversity of the indoor air conditioning mode of the air conditioner indoor unit is improved.
