Is heat exchanger part of HVAC?
Maintaining Your HVAC Heat Exchangers These components are designed to use less energy during the heating and cooling process for a more energy efficient system. As such a vital component of your HVAC system, it is essential to ensure that your heat exchangers continue to operate efficiently.
What are the different types of heat exchangers?

How does the heat exchanger work?
Heat exchangers, metal shells and tubes, work by transferring heat from one place to another. The hot flue gas heats the metal as the gas makes its way to the exhaust outlet of the furnace. As this is happening, the hot metal heats the air circulating over the exterior of the heat exchanger.
Which type of heat exchanger is used in air conditioner?
All air conditioning systems contain at least two heat exchangers, usually called the evaporator and the condenser. In either case, evaporator or condenser, the refrigerant flows into the heat exchanger and transfers heat, either gaining or releasing it to the cooling medium.
What does a heat exchanger do in HVAC?
What Is a Heat Exchanger in HVAC? A heat exchanger is a device that transfers thermal energy from one medium to another. Heat exchangers not only assist in the cooling and heating of homes and buildings, but also help machines and engines work more efficiently.
What’s the purpose of a heat exchanger?
Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact.
What is heat transfer in HVAC?
A heat exchanger in an HVAC system uses conduction to transfer heat. This is the traveling of heat energy from one molecule to another using direct contact with the temperature source. HVAC heat exchangers will either heat or cool the air with conduction, but they need the proper medium from which to get the energy.
Which type of heat exchanger is more efficient?
The plate type heat exchanger is the most efficient type of heat exchanger with its low cost, flexibility, easy maintenance, and high thermal transfer. WCR plate corrugations are designed to achieve turbulence across the entire heat transfer area. This produces the highest possible heat transfer coefficients…
What is the heat exchanger in a furnace and how does it work?
A furnace heat exchanger works by literally exchanging (or transferring) the heat created in the combustion chamber to the exterior of the unit, where it is then blown through the ductwork throughout the house.
What is the process of a heat exchanger?
It works by burning natural gas , making a line or grid of hot gas jets that fire upward over water flowing through a network of pipes. As the water pumps through the pipes, it absorbs the heat energy and heats up. This arrangement is what we mean by a heat exchanger: the gas jets cool down and the water heats up.
What does the heat exchanger do?
heat exchanger. n. A device, such as an automobile radiator, used to transfer heat from a fluid on one side of a barrier to a fluid on the other side without bringing the fluids into direct contact.
