What is the principle behind HVAC (Heating, Ventilation, and Air Conditioning) systems?

Question

Accepted Answer

HVAC systems control the temperature, humidity, and air quality in a building by circulating air through heating and cooling units.

HVAC systems work by controlling the temperature, humidity, and air quality in a building.
They use a combination of heating, ventilation, and air conditioning units to achieve this.
Heating units like furnaces or boilers provide warmth during cold weather.
Ventilation systems circulate fresh air and remove stale air to maintain indoor air quality.
Air conditioning units cool the air during hot weather.
HVAC systems can also include filtration and purification systems to improve air quality.
Proper maintenance and regular inspections are essential to ensure HVAC systems function efficiently.
