At present, common air conditioners include wall-mounted air conditioners, vertical cabinet air conditioners, window air conditioners and ceiling air conditioners. Among them, vertical cabinet air conditioners are used by more and more families because of their advantages such as wide-angle air supply.

At present, the vertical cabinet air conditioners on the market are located at a relatively high distance from the ground. When the air conditioner is heating, the density of the air with a high temperature is lower than that of the air with a low temperature. It will be difficult for the hot air blown by the air conditioner to settle to the ground in the heating mode, which will cause the phenomenon of stratified distribution of room temperature. Although the average temperature in the room is higher than the outside, The temperature is lower than that near the ceiling, so the human body feels hot on the top and cold on the bottom, resulting in an obvious phenomenon of "hot head and feet cold", and the experience effect is poor.

Fresh air air conditioner is a healthy and comfortable air conditioner with fresh air function. It uses centrifugal fan to realize the circulation and ventilation between room air and outdoor air, as well as the effect of purifying air, while fresh air air conditioner only provides outdoor air induction. When the fresh air function is not in use, it will be in an idle state, and the fresh air conditioner in the idle state cannot perform indoor air circulation, that is, there is currently no fresh air fan used in the air conditioner to achieve indoor cooling and heating.
