Study Notes
Benefits of Ceiling Fans
- Summer Cooling: Provide a breeze that enhances comfort during hot weather.
- Winter Heating: Re-circulate warm air from the ceiling to warm the space below.
- Energy Savings: Operate efficiently, leading to reduced energy costs in heating and cooling.
- Ambient Illumination: Often include light fixtures, adding to room brightness.
- Aesthetic Appeal: Available in various designs, enhancing interior decor.
Pancake Motor
- Common Motor Type: Characterized by a smaller height in relation to its diameter, favored for ceiling fans due to its efficiency.
Bearings
- Functionality: Support moving parts in the motor, minimizing friction and wear.
- Self-Lubricating: Most modern bearings are designed to reduce maintenance.
Fan Efficiency
- Labeling: Fans rated based on airflow produced per watt of electricity consumed, indicating energy performance.
Wind Chill Effect
- Airflow Mechanism: Fans create a downward airflow, making the air feel cooler and more comfortable for occupants.
Winter Heating Mechanism
- Re-Circulation Role: Fans help distribute warm air that gathers near the ceiling, improving overall temperature in the room.
Factors Affecting Airflow and Performance
- Motor Speed: Influences how much air is moved.
- Blade Surface Area: Larger blades can move more air.
- Blade Pitch: The angle of blades affects airflow dynamics.
- Blade Sweep Diameter: Diameter of the fan’s rotation impacts the amount of air circulation.
Ceiling Fan Light Kits
- Regulation Requirement: Must come with compact fluorescent lights (CFLs) for medium-based sockets as per federal guidelines.
Fan Sizes
- Importance: Size influences fan performance and appropriateness for specific room dimensions (details not provided).
