What is the operating principle of the air curtain?

The air curtain generates a high-speed air flow, divides the indoor and outdoor area into two independent temperature ranges to create a pleasant indoor climate, maintains the effect of indoor air conditioning and cleaning, saves electricity and circulates the air, to effectively isolate dust and smoke and smell microorganisms such as air and insects. The continuously shaped air door can effectively prevent the release of cold (warm) air, save electricity and divide the interior and exterior area into two independent temperature ranges. When the air conditioning runs longer, it supports the circulation of temperature settings to save energy and improve the environment. Purpose. The air curtain with a dust and insect protection effect produces a high-speed airflow to form a protective door that can effectively block the entry of external dust and flying insects and keep the room clean. The air circulation system of the air curtain with anti-smoking and harmful gas effects can make any corner of the room a strong barrier against the spread of spicy fumes and industrial gases, car exhausts and other harmful gases. Air circulation Effect If the energy distribution of the air conditioner is uneven due to the large space in stadiums, cinemas and entertainment centers, the air circulation system function of the air curtain can achieve the internal temperature balance.

What calculation methods are available for air curtain?

(1) calculation method based on the impulse principle;

(2) the calculation method using the combination of jet wind speed and door opening wind speed;

(3) with regard to the radiation flow and the opening air flow as a potential flow, the coating calculation method;

(4) calculation procedures based on the principle of natural ventilation;

(5) The calculation method based on the experimental diagram.

Where is the scope of the air curtain?

Use of air curtain. The air curtain is installed via the doors of refrigerated, air-conditioned, dust and heat-insulated shopping centers, theaters, hotels, restaurants, conference rooms, cold stores, operating rooms and apartments. Start the machine to separate the inner and outer air. It is convenient to enter and leave and can prevent the exchange of hot and cold air inside and outside. At the same time, it has the effect of preventing dust, pollution and mosquitoes.

Aerospace cleaners are also frequently used in sectors such as electronics, instrumentation, pharmacy, food, precision processing, chemistry, footwear and services, trade, etc. used.
