DBF wind chassis series is the company one of the series of air conditioning products, high-pressure polyurethane foam slab structure, with low noise YDW double inlet fan and Chip Primary filter combination. In industrial production, the supply and exhaust for use with buildings, commercial entertainment, culture, education and health sectors of air conditioning engineering systems. Has a small wind chassis manufacturers, insulation performance, light weight, low noise, simple operation and maintenance features. According to the working principle of centrifugal fan is the principle of potential energy is converted to kinetic energy, the use of high-speed rotating impeller accelerates the gas, and then slow down, change the flow of the kinetic energy into potential energy (pressure). In the single-stage centrifugal fan, the gas from entering the impeller axis wind chassis brand, changing the gas flow through a radial impeller, and then into the diffuser. In the diffuser in HTFC-11 dual-speed centrifugal wind chassis, the gas flow direction changes caused slowdown, which would slow down the role of the kinetic energy is converted into pressure energy. Increased pressure occurs mainly in impeller stroke chassis, followed by the process occurs in the diffuser. In a multi-stage centrifugal fan, and reflux into the next impeller allows airflow, resulting in higher pressure. Two-speed exhaust air box _ Chenyu air conditioning (certified) _ Xinzheng wind chassis provided by Wu Cheng Chen-yu air-conditioning Limited. Wu Cheng Chen Yu Air Conditioning Equipment Co., Ltd.
