According to effective pressure circulating type air curtain air curtain theoretical study and the characteristics of the air curtain blocking mechanism, for example Air Curtain in Mine. The results obtained with a romantic air curtain back off the roadway and control of air flow inside. Its better than manual or automatic throttle. To solve the problem of leakage of underground transport busy roadway opened up new avenues. Thus ensuring the normal flow of underground romantic, help protect the health of workers and the safety of underground production, the mine has broad application prospects. The same section of the main ramp and roadway sides cave room. 4 turbines connected in parallel with the air curtain ramp to increase air flow into the barrier has played a role in regulating the windscreen. When the air temperature is below -lO ℃. Main ramp of the air curtain full. Air temperature is 0 ~ -lO ℃, the open side of the air curtain. When the air temperature is greater than O ℃. To effectively block the smoke, the air curtain inclination angle must be greater than zero. In formula describes the air curtain can stop flue gas conditions. A building more than 50m (13 ~ 22F) staircases in the front room and shared room at the entrance to set up two air curtain. Evacuation of air curtain protection front room and the stairs near the diffusion of smoke a flow process, the fire source maximum power of 1.15MW, fire growth factor O.O8 kw / s square by CFD simulation model. Mechanical exhaust ventilation amount of 65OO m cubic meters / h, the air curtain outlet velocity of 11m / s, the maximum flow of 235O m cubic meters / h. After the simulation results 12Os smoke entered the front room. The amount of smoke to 125O0m cubic meters / h, the smoke does not enter the smoke before the room. Tips: When you buy air wind screen you try to provide the use of a machine on site, how many meters from the ground installation location, how high lintel above the door, what material, in the case of glass or something, the best photo . 2, the air curtain door installation tall, wide, toward the door. 3. What is the heat source to be used: electricity (power, from the power supply chamber can provide the number of meters to be installed machine), hot water (number of degrees), steam (steam, etc.), 4, what places and sound requirements. 5, Texas air-conditioning plant Watson of goods sold non-small items in your order before you must notify the seller phone to help you timely delivery. 6, under normal circumstances, within 10 commonly used models are available from stock, the same day at 13:00 in play money before arrival, or pay-fighting arrival. It can be shipped the same day, in Texas warehouse directly shipped to the country. But the company is for the sale, order time is not fixed, it is sometimes too late to update the site, so the number displayed on the website is not necessarily real number of inventory items, so be sure to call to confirm the money in your orders. 8, the company sold products for commercial or industrial, non-Taobao goods sold, so much for the next line transactions, transaction records if you do not see on the Internet, does not mean that there will be no deal for this item before. Blowing air curtain form, commonly used to send there, side feed type and bottom feed three. Sent to the air curtain: air curtain installed in the upper part of the doorway. Sent to the air curtain installation is simple and does not account for the construction area, it does not affect the architectural appearance, blowing air flow better sanitary conditions for the general public buildings. Despite sending air curtain blocking efficiency is not as cold outdoor air curtain delivery, but it is still a form of the most promising. Usually the door air curtain sole purpose of blocking the outdoor cold (hot) air, usually only provided the air outlet, no return air, so free jet diffusion to the room and on the ground after contact, the door air curtain air curtain called simple. Side curtain air delivery: air curtain mounted on the side of the doorway, divided into two kinds of unilateral and bilateral. Industrial buildings, when the outer door width less than 3M, should adopt unilateral air, when the outer gate width of 3 ~ 18M, should adopt unilateral or bilateral air, or down on the air. In order not to block the air flow, equipped with side curtain air delivery doors open inward prohibited. By sending air curtain: air curtain is installed under the ground. Due to lower feed air curtain jet strongest area in the lower openings, and therefore resist the winter cold wind from the bottom openings when invade the efficiency of the best, and not affect the direction of the door opening.
