The working principle of the air curtain is to allow the high-speed jet of air to form a wall. The air curtain uses a special high-speed motor to drive the tubular, centrifugal or axial-flow fan to generate high-speed airflow, forming a strong airflow barrier, dividing the indoor and outdoor into two independent temperature zones.
What are several ways to calculate the efficiency of the air curtain according to the principle?
What is the application field of the air curtain machine?
Knowing the area that the user needs to heat, how much power should the air curtain be configured?
(1) The calculation method according to the momentum principle;
(2) The calculation method using the combination of jet wind speed and door-hole wind speed;
(3) The calculation method of superimposing the jet and the door-hole airflow as a potential flow;
(4) Calculation method according to the principle of natural ventilation;
(5) Calculation method according to the experimental chart.
The air curtain machine is installed above the door of the refrigeration, air conditioning, dustproof and heat insulation shopping malls, theaters, hotels, restaurants, conference halls, refrigerators, operating rooms and households. Open, not only to facilitate access, but also to prevent the exchange of indoor and outdoor hot and cold air.
At the same time, it has anti-odor, anti-pollution and anti-mosquito effects. air curtains have been widely used in electronics, instrumentation, pharmaceuticals, food, precision processing, chemicals, shoemaking, services, commerce and other industries, creating a good business environment for many businesses.
1. The height of the house shed is less than 3m. If there is no heating equipment, it is calculated according to the configuration of 200W ~ 300W per square meter (normally, it is equipped with 200W per square meter, and if the room is not well insulated, it is calculated according to the configuration of 300W per square meter).
Example: What is the heater power required for heating a room of 40 square meters?
40 square meters × 200W=8000W=8KW
2. The height of the shed is less than 3m, and there are heating facilities but the heat is not enough. The auxiliary heating with heating equipment is calculated according to the configuration of 100W per square meter.
Example: 100 square meters of living room: 100 square meters × 100W=10KW
3. If the height of the shed is more than 3 meters, calculate the result according to the above method, multiply the actual height and divide it by 3M.
Example: a room of 50 square meters, the room has normal insulation, and the height of the shed is 5.6M
50 square meters×200W×5.6/3=18.7KW
