Watson air curtain air-conditioning plant shop door hot and cold air curtain

Texas Watson manufacturers air curtain is strong air flow generated by the wind turbine tubular form one side of an invisible curtain, therefore, also known as air curtain machine, air curtain, air curtain air, dampers, air door. Air curtain for: refrigeration, air conditioning, dust, insulation of shopping malls, theaters, factories, hotels, restaurants and other door, the upper air curtain installed in 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. For demanding building, in order to better organize the airflow, the air outlet is located at the top of the door, the floor set back air, circulating air through a filter after use, heating and other treatment. 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. Mining air curtain is a high-speed motor driven centrifugal wind wheel tubular or produced strong air flow, forming one side of an invisible curtain. Therefore, also known as air curtain, air curtain air curtain air, dampers, air curtains, electrical mine air curtain is to use electrically heated air curtain. Mining air curtain is put energy into heat energy of high-power electrical equipment, because of its large and secure the release of heat, using a wide range, much favored by the market. Mining air curtain is generally not installing air filters, because the installation of the air filter, will increase the air intake resistance and reduce the intake of the number, it increases the load on the heater --- (PTC heater consists of a number ceramic piece combination) when the air curtain when the mining work is energized heater and fan work, power and PTC ceramics rapid warming, then sent wind turbine high temperature heat PTC ceramic chip away the surface, reducing the PTC ceramic the temperature of the sheet surface. Although the general mining air curtain without air filter, but the air will be a lot of dust particles, which will work with the mining air curtain air curtain into the surface mining in heaters, air curtain mining longer used, airborne dust particles accumulate on the surface of the heater is also more thick, which would affect the rate of heat PTC ceramic plate (heater heat dissipation rate), increasing the overall temperature of the mining air curtain body, will also affect fans stability and lifetime effects of the heater.
