Because an air curtain is generally set up at the entrance point, that is, a strong air flow is continuously sprayed from above to the bottom to obstruct the convection of the air. When the door of the store is opened, the air in the store and the air outside are convection, which will cause the energy consumption of the air conditioner to rise, just like when you open the air conditioner at home. The air curtain can alleviate this problem by blocking the air convection to a certain extent, so you will feel a strong gust of wind blowing on you when you enter the door. Wish.
