HVAC (Heating, Ventilation, and Air Conditioning) systems are a collection of equipment and systems that work together to provide comfortable and healthy environmental conditions in buildings and enclosed spaces.
Heating systems aim to increase the interior temperature of the environment, while cooling systems aim to decrease it. Ventilation systems, on the other hand, aim to provide fresh and clean air to the environment by removing stale and impure air.
These systems typically include equipment such as heating and air conditioning units, air ducts, fans, filters, heat exchangers, circulation pumps, thermostats, and controllers. HVAC systems can be designed in various ways, depending on the space's needs and local weather conditions.
HVAC systems are important not only to ensure the comfort and health of occupants but also to protect sensitive equipment in the environment, such as computers and electronics. They can also ensure air quality in critical environments like hospitals, laboratories, and others. Furthermore, these systems can be designed to improve the building's energy efficiency, reducing operational costs and minimizing environmental impact.
