HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the technology and equipment used to regulate temperature, humidity, and air quality within a building and space. The primary function of HVAC systems is to maintain indoor air quality and comfort by providing heating, cooling, and ventilation.
HVAC systems can include a variety of components and equipment including heaters, air conditioners, ventilation systems, and ducts & vents.
A part of HVAC called refrigeration involves moving heat from one place to another in order to keep a particular temperature. This method transfers heat from the air within a building or other place to the outside through air conditioning equipment. Additionally, refrigeration is utilized for a variety of other purposes where precise temperature control is necessary, including the delivery and storage of food.
