Air curtain by air handling equipment, fans, and air distribution duct system composed. The machine installed in refrigeration, air conditioning, dust, insulation of shopping malls, theaters, hotels, restaurants, conference rooms, cold storage, and home theater and other hot and cold air above the entrance door of the industrial air curtain, start the machine, can indoor separated from the outside air, played only accessible, but also to prevent the exchange of indoor and outdoor hot and cold air at the same time, with dust, pollution prevention, anti-mosquito effect. We produce such an air curtain can be widely used in electronics, instrumentation, pharmaceutical, food, precision machining, chemical, footwear, and services, business, etc. industries. Hot air curtain is put energy into thermal energy of high-power electrical equipment, its large and secure the release of heat, using a wide range, much favored by the market. Can be divided according to the appearance of large air curtain: mainly used in shopping malls and large energy and mining enterprises, hot air curtain, door seal better. Small air curtain: installation height of not more than 3 m, the smaller the energy consumption of the air curtain. Electric air curtain: easy to use, Dezhou air curtain manufacturers, non-polluting, low-cost air curtain installation, affordable and effective. Hot air curtain: the system piping water temperature and other demanding mine mouth hot air curtain, the general effect. Steam air curtain: large steam consumption by limiting the amount of steam boilers, the best results. According to the effective pressure circulation type air curtain air curtain off the theoretical study and the characteristics of the mechanism of the air curtain, air curtain application example in Mine. The results come back off the air curtain has a Merry Merry and control of roadway within. Its better than a 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 mine production safety at the mine has broad application prospects. In the same section of the main ramp, on both sides of the roadway cave room. Typhoon aircraft with four parallel composition of the intake air curtain ramps increase airflow resistance plays a role in regulating the windscreen. When the air temperature is below -lO ℃. Main ramp full of air curtain. Atmospheric temperature is 0 ~ -lO ℃, the open side of the air curtain. When the air temperature is greater than O ℃. To effectively block the smoke, air curtain inclination angle must be greater than zero. In formula describes the air curtain can stop the smoke conditions. A building more than 50m (13 ~ 22F) staircases front room and shared room at the entrance to set up two gas-screen machines. Protection curtain air evacuation stairs near the front room and the spread of a fire smoke flow process, the fire source maximum power of 1.15MW, fire growth factor O.O8 kw / s squared by CFD simulation model. Mechanical exhaust ventilation amount of 65OO m cubic meters / h, 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 / h, the smoke does not enter the front room of smoke. Plumbing hot air curtain air conditioning _ Watson (certified) _ air curtain is provided by the Texas Watson air-conditioning plant. Texas Watson air-conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Watson air conditioning in leadership with the staff warmly welcome all inquiries negotiations to create Watson conditioned a better future.
