1. Components of HVAC Systems

Key components of HVAC systems include:

?? Heating Systems: Heating systems such as furnaces, boilers, heat pumps, and radiant heaters provide warmth during cold weather by transferring heat energy to indoor spaces.

?? Cooling Systems: Cooling systems such as air conditioners, chillers, and evaporative coolers remove heat from indoor spaces, maintaining comfortable temperatures during hot weather.

?? Ventilation Systems: Ventilation systems ensure the circulation of fresh outdoor air and the removal of indoor air pollutants, promoting healthy indoor air quality and preventing the buildup of harmful contaminants.

?? Air Distribution Systems: Air distribution systems, including ductwork, vents, and diffusers, distribute heated or cooled air evenly throughout buildings, ensuring uniform comfort levels in every room.
