The Basics of Heating and Cooling Systems
Heating and cooling are some of the most important factors to a home or office building because they are critical for creating a comfortable environment. HVAC, or Heating, Ventilation, and Air Conditioning systems are responsible for performing the three main functions of comfort inside a home or building: controlling air temperature, humidity, and quality of air. Keeping these systems maintained and performing repairs when needed is a huge industry and companies are looking to fill thousands of positions with skilled and knowledgeable technicians. ATI’s HVACR Training program in Las Vegas will equip students with the training and knowledge to successfully install, service, and repair both residential and commercial heating and cooling systems.
Let’s take a look at the two main types of cooling and heating systems, central heating and air conditioning. Central A/C systems are split systems. This means they have an outdoor unit, called a compressor bearing unit, and indoor coil which is normally found on the top of the furnace. The compressor circulates coolant through the system to gather heat and moisture from inside the building and transfers it outside. The heat and moisture filled air is blown over the cooled indoor coil which captures the heat and moisture and expels cooled air. The heat that is now stored in the coil gets pumped outside while the cooled air gets distributed throughout the space.
Central heating systems use a furnace to keep a home warm during the colder times of the year and it also plays a critical role in the operation of the air conditioning system. A furnace produces heat through the combustion of natural gas in the furnace’s burner. The heat that is created is then passed through a heat exchanger. Air from the home is blown over the heat exchanger which warms up the air. The furnace houses a blower which blows the warmed air into the buildings ducts and disperses it warming the entire space. During the colder months the furnace still utilizes the blower, only now the return air that is sent back into the home has been cooled by the indoor coil part of the A/C system.
The benefits of these heating and cooling systems are what make them widely popular for both residential and commercial buildings. They are more energy efficient, provide cleaner air, and create a comfortable environment for the people inside.
