Fans and Blowers Bureau of Energy Efficiency pressures upto 500 mmWC. 5. Total static pressure, = 468.75 – (–22.33) = 491 mmwc (∆ p. tions, and efficiency. In axial flow, the air that enters the fan leaves it without any change in the direction. Could you please explain more about this phrase: "efficiency of fan is less than 1 and refrigerator is about 3"! As the air moves from the impeller hub to the blade tips, it gains kinetic energy. Switch to new, energy-efficient light bulbs: Compact Fluorescent Lamps (CFLs) or Light Emitting Diodes (LEDs). Examples include centrifugal fans, blowers and pumps. ... or bathing; when replacing exhaust fans, consider installing high efficiency, low-noise models. (see Figure 5.2). fan efficiencies are given in Table 5.2. Propeller fans usually run at low speeds and moderate temperatures. Potential sealing system savings can exceed the energy savings obtained from switching to variable frequency drives, trimming impellers, or re-sizing pumps in many applications. • Eliminate variable pitch pulleys. 0000003381 00000 n A fan that is rated at FEI 1.1 provides the following energy savings over the baseline requirement: (FEI 1.1) - (FEI 1.0) = 0.1 Energy Savings i.e. 0000008171 00000 n 93Bureau of Energy Efficiency 5. 0000007987 00000 n AND COMPRESSOR pump.
