The equivalent of a large refrigerator for your home is a central air conditioner. As a matter of fact, it uses the same parts, materials, and processes as a refrigerator, including a refrigerant that transforms between liquid and gas before returning to liquid as it passes through a network of tubes and coils or fins that trap and release heat.
It distributes heat from one location to another as it completes this cycle. It simultaneously generates cold (the lack of heat) in one location and transports that chill to another. The area that receives the cold in the case of an air conditioner is an air handler or furnace cabinet that has a fan that distributes the chilly air throughout your home.
Usually, the air handler or furnace is placed in a remote area like the basement or attic.Through a network of air ducts, this appliance distributes chilled air throughout the home. During the heating season, a forced-air furnace frequently uses the same network. The cooling system is turned on and off in the home using one or more thermostats in response to changes in room temperature.
