HVAC, or Heating, Ventilation, and Air Conditioning is the science of vehicular and indoor environmental comfort. The intent of HVAC is to provide acceptable indoor air quality and thermal comfort for the occupants of the building. HVAC includes a wide range of system technologies to deliver comfortable indoor air through a properly controlled heating and ventilation system. These systems include heating and ventilating systems such as air-conditioning, liquid cooling, and gasification. Some of the more advanced HVAC technologies include energy management, including demand, energy efficiency, and environmental response.
Heating, Ventilation, and Air Conditioning (HVAC) are the science of vehicular and indoor environmental conditioning. Its purpose is to provide acceptable indoor air quality and thermal comfort for a wide range of applications. HVAC systems control the internal temperature of a building or other structure by regulating the flow of air, controlling internal temperatures, controlling energy use, and regulating the temperature of water used for outdoor irrigation and bathing. HVAC services are provided by many companies. There are many types of HVAC systems such as heating and cooling, air conditioning, and central air conditioning.
