Low-noise wind chassis; low-noise wind chassis is a new wind power source wind chassis brand, compared with conventional ventilation wind chassis performance, with large air volume, low noise, low power consumption, easy on-site installation and removal features. Direct fan uses a low-noise fan wind chassis, especially for general plant, civil, education, research and office building ventilation and air conditioning system pressure and other series. E-type transmission using the company designed specifically for the air conditioning low noise series two-speed exhaust fan wind chassis, while the post-retrofit energy supply and exhaust air box in addition to outside, but also discharge air temperatures above 280 ℃ continuous operation 100 minutes. 1. The choice of the control parameters for wind chassis air flow, total pressure, efficiency, noise, and electrical power. There are centrifugal and axial flow. Fan since the wind chassis, is conducive to the muffler. 2, in the selection of fan model, first consider the leakage loss of piping systems, calculation errors, as well as the actual fan wind, air pressure of the negative bias. 3. Moreover, you should pay attention to the relationship between the pipe network resistance characteristics match with the fan characteristics.
