Blowers
Blowers Blowers are an essential component of HVAC systems, responsible for: 1.Air circulation: Moving air through the system and building. 2.Pressure increase: Boosting air pressure to overcome system resistance. 3.Air distribution: Distributing conditioned air to various zones or spaces. Types of blowers: 1.Centrifugal blowers: Use a spinning impeller to increase air pressure. 2.Axial blowers: Use a spinning propeller to move air. 3.Cross-flow blowers: Use a cylindrical impeller to move air. 4.Regenerative blowers: Use a spinning impeller to increase air pressure. Key characteristics of blowers: 1.Flow rate: Measured in CFM (cubic feet per minute). 2.Pressure rise: Measured in inches of water gauge (in wg). 3.Efficiency: Measured by fan efficiency grade (FEG) or fan motor efficiency. 4.Noise level: Measured in decibels (dB). Factors affecting blower performance: 1.Proper sizing and selection. 2.Regular maintenance and...
