[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - no power ventilation fan None power Uses: 1, resulting in an air convection cooling exhaust gas. 2, to reduce the air conditioning load, increase the indoor fresh air. 3, the moisture out of the roof, Mei Qi, steam, keep the roof dry. 4, instead of heavy-duty electric blower, reduce electricity cost savings bracket, subtract noise. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan Fan] the main performance parameters of flow, pressure, power fan, efficiency and speed. In addition, the noise and vibration of the size of the fan is the main technical indicators. Air volume flow rate, also known as boiler fans, to the unit of time, said the volume of gas flowing through the fan; pressure, also known as pressure exhaust fan fire, refers to the value of the gas pressure rise in the fan, there is static pressure, dynamic pressure and total Pressure points; power is the fan input power, namely shaft power. Effective power and fan shaft power ratio referred efficiency. Fan total pressure efficiency up to 90%.
