NuTone is an American company that manufactures products mainly for residential use, including doorbells, intercom systems, indoor air quality products, ventilation systems, range hoods, ceiling fans, built-in electric heaters, ironing equipment, and home theater systems. The company was founded in 1936 by J. Ralph Corbett in Cincinnati, Ohio. [1]
Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
The effectiveness of displacement ventilation at removing particulate contaminants has been investigated recently. [13] [14] Small aqueous droplets containing infectious nuclei are frequently released in hospital rooms and other indoor spaces, and tend to settle through the ambient air at a speed of order 1–10 mm/s typically. In cold climates ...
For residential buildings, which mostly rely on infiltration for meeting their ventilation needs, a common ventilation rate measure is the air change rate (or air changes per hour): the hourly ventilation rate divided by the volume of the space (I or ACH; units of 1/h). During the winter, ACH may range from 0.50 to 0.41 in a tightly air-sealed ...
A cross-flow fan is a centrifugal fan in which the air flows straight through the fan instead of at a right angle. The rotor of a cross-flow fan is covered to create a pressure differential. A cross-flow fan has two walls outside the impeller and a thick vortex wall inside. The radial gap decreases in the direction of the impeller rotation.
An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...
