HVAC is a shortened term for Heating, Ventilation and Air Conditioning â€“ related technologies dealing with indoor climate control. HVAC technology has been developing since the industrial revolution, and the systems and tools used are constantly evolving, with new innovations being introduced all over the world.
Heating, ventilating, and air conditioning technologies are used to provide warmth and comfort in cold climates, to improve the quality of air indoors, and to keep buildings comfortable when outdoor temperatures become unbearable.
HVAC, specifically air conditioning, is particularly important in arid American cities, such as Phoenix, Arizona, where the temperature hits 100Â° over 100 days per year, on average, putting Phoenixâ€™s climate on par with Baghdad and other Middle-Eastern cities.
Heating systems often differ in their central components, which can include boilers, furnaces, or even heat pumps, which draw heat from the air or ground and convert it to either heat or cool air.
Ventilating may be done through either forced ventilation, which uses fans & other technology to draw or force air movement and improve air quality, or natural ventilation, which involves utilizing natural convection and allowing warm air to rise and escape while cool air is drawn in naturally.
Air conditioning is often misunderstood as the creation and circulation of cold air. The technology actually works to remove heat from the air, leaving the indoor climate cool and comfortable.
In the past few decades, technological developments have allowed for great improvements in HVAC system energy efficiency. Other technologies, such as Geothermal Heat Pumps and radiant floor heat, are becoming more popular due to their efficiency as well.
