Corrosion centrifugal fan, motor (motor) driven impeller rotating within the volute casing, the air sucked through the intake port from the impeller center. Due to the dynamic action of the blades on the gas, the gas pressure and speed can be improved, and the centrifugal force along the road leaves the cabinet Shuaixiang discharged from the exhaust port. Corrosion centrifugal fan impeller and casing composed mainly of small fan impeller is mounted directly on the motor, the large centrifugal fan corrosion by coupling or connection with the motor pulley. Usually unilateral corrosion centrifugal fan inlet, with a single-stage impeller; flow can be bilateral air intake, with two back to back impellers, also known as double-suction centrifugal fan central air conditioning fan coil corrosion can follow calandria number divided: two rows of tubes, three rows of tubes; there are two control points and four controls: two controls that ordinary fan coil go cold summer cooling and winter heating hot water go; four pipe fan coil used for some of the more luxurious places you can go hot and cold at the same time, which can refrigeration needed some room, some rooms warm. Two rows of tubes into a cold summer Chongqing sidewall fan, one out of cold water into a hot water in winter, a hot water; three rows of tubes are two water, into a cold, feed a hot Water sidewall fans, while a water. Principle: The fan coil rely mainly on the role of fan forced dwex type sidewall fan, when the air is heated by the heater surface, and thus strengthen the convection heat exchanger between the radiator and the air blower zaoqiang fiberglass sidewalls, quickly heating room air. Fan coil air conditioning system is the end of the device, which works out constantly recycling unit mounted inside the room where the air duct, the air through the cold water (hot water) after the cooling coil (heating) in order to keep the room temperature constant. Typically, after the new air handling unit into the room to meet the needs of fresh air conditioned room dwex type sidewall fans, Hao Yang air conditioning equipment (certified), Sidewall Fan Yang Hao provided by the Texas Air Conditioning Equipment Co., Ltd .. Air Conditioning Equipment Co., Texas Hao Yang (www.dzapjt.com) is a leader in Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Hao Yang air conditioning equipment in leadership with the staff warmly welcome all inquiries negotiations to create Hao Yang air conditioning equipment a better future.
