The function of air curtains:
(1) Insulation Function: The wind curtain eliminates the need for continuous door opening and closing in frequently accessed areas like restaurants and stores. This maintains indoor air temperature at 60-80% efficiency, allowing only minimal temperature fluctuations.
(2) Insect Protection: The windbreak wall effectively blocks most pesky and harmful insects, making it easier to maintain cleanliness in areas like fruit counters and fast-food restaurants.
(3) Dustproof Function: Installing air curtain machines in precision machinery factories or in the entrances of food stores or clothing stores facing bus lanes can effectively block outside dust, maintaining cleanliness at a level of 60-80%.
(4) Freshness Function: The air curtain machine can prevent unpleasant odors from escaping from mechanical sources such as chemical laboratories, store coolers, and frozen meat storage, as well as block harmful gases emitted by outside vehicles. Regarding the prevention of air conditioning cold and hot air leakage, experts suggest that the air curtain machine should be integrated with air conditioning for effective resolution of these issues.
(5) Negative Ion Function: Generates active oxygen, improves lung function, boosts metabolism, enhances sleep quality, sterilizes, creates fresh air, removes smoke and dust, prevents myopia, and prevents static electricity from causing split ends.
The principle of the air curtain is to create a wall of high-speed airflow. The air curtain utilizes a special high-speed motor to drive impeller rotors, either axial, centrifugal, or mixed flow, to generate a high-velocity airflow, forming a powerful air barrier that divides the indoor and outdoor areas into two separate temperature zones.
Air curtain machines generate high-speed air currents, dividing the indoor and outdoor spaces into two separate temperature zones to create a comfortable indoor environment. They maintain the effectiveness of air conditioning and air purification, save electricity, and facilitate air circulation, effectively isolating dust, smoke, odors, and insects. The continuously formed air barrier effectively prevents the escape of cold (or warm) air, saves energy, and divides the indoor and outdoor spaces into two independent temperature zones. During prolonged operation of air conditioning units, they assist in temperature regulation to achieve energy conservation and environmental improvement. The dust and insect-proof effect: The high-speed air flow generated by the air curtain machine forms a protective barrier, effectively blocking outdoor dust and flying insects from entering, maintaining indoor cleanliness. The smoke and harmful gas-proof effect: The air circulation system of the air curtain machine effectively prevents the spread of smoke, pungent odors, industrial emissions, and vehicle exhausts from entering the indoor space. The air circulation effect: In large spaces like stadiums and cinemas where air conditioning energy distribution is uneven due to the size of the space, the air circulation system of the air curtain machine ensures uniform indoor temperature.
