The answer to 'what is heat exchanger' is a critical component of a furnace or air conditioning system that transfers heat from one medium to another. It is responsible for efficiently transferring heat from the hot air produced by the combustion process or refrigerant in an AC system to the air that is circulated through the ductwork and into the home. The heat exchanger is designed to maximize the surface area for heat transfer while preventing the combustion byproducts from mixing with the air that is distributed throughout the home.
A well-functioning heat exchanger is essential for the safe and efficient operation of a furnace or air conditioner. It helps ensure that the heated or cooled air is delivered to the living spaces as intended, without any dangerous gases or contaminants. Regular inspection and maintenance of the heat exchanger is important to identify any cracks or damage that could compromise its performance and pose safety risks.
