AI Technical Summary
Existing air curtain machines experience negative pressure at the air inlet during operation, and the airflow at the outlet is affected by the pressure difference, resulting in a short blowing distance and high energy consumption.
A novel high-efficiency circulating air curtain machine is designed. It utilizes two support legs of a gantry frame and an enclosure plate to form a convection air outlet and air inlet channel, allowing the airflow to circulate between the support legs. The airflow path is optimized through air guide plates and refrigerant pipes to reduce diffusion and extend the blowing distance. At the same time, the negative pressure of the fan is used to create an adsorption effect, reducing energy consumption.
It achieves the goal of extending the blowing distance of the airflow in the air curtain under relatively low wind conditions, thereby improving the air curtain effect and reducing energy consumption.
