Understanding HVAC Systems
What is HVAC and How Does It Work?
The term HVAC stands for Heating, Ventilation, and Air Conditioning. Essentially, it encompasses the various systems and technologies designed to provide thermal comfort, enhance indoor air quality, and effectively manage the temperature and humidity levels within buildings. An HVAC system operates through a network of units working together to ensure a comfortable environment for occupants. This process involves drawing outside air, filtering it, conditioning it through heating or cooling units, and distributing the treated air throughout the space via ductwork.
A typical HVAC system consists of a furnace or boiler, an air conditioner, a heat pump, and a duct system for ventilation. In more advanced configurations, additional components may include air handlers, humidifiers, and smart thermostats to optimize system performance and energy efficiency.
