The Efficient Approach to Air Conditioning in DenverForced air A/C (air conditioning) works off the same system of ducts and vents your heating systems uses. Air conditioning is the process of removing heat from a confined space, thus cooling the air in that room. Forced air heating and cooling units are designed to maintain uniform temperature throughout a space by cooling air in a central location and then pushing (or “forcing”) the cooled air throughout the duct work in the home and into the individual rooms. The most common type of air conditioning systems uses a compressor cycle to transfer heat from your house to the outdoors, allowing the cool air to have more of an effect.
Used in millions of residential and commercial spaces throughout the United States, the process is performed to create a more comfortable interior environment. In addition to creating a more comfortable thermal environment, air conditioning can also improve indoor air quality.
A Central AC System with Forced Air Cooling
A popularly used heating and cooling unit designed and used to cool the entire house is known as the central air conditioner. Similar to the manner in which heat is distributed throughout a home or office, central air conditioners use a fan to distribute the cool air throughout the building. Cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Some air conditioning systems use desiccants, which are chemicals which remove moisture from the air, and offer added comfort in humid environments.
Since 1992, central air conditioners, included in heating and cooling units, come with a rating system according to their seasonal energy efficiency ratio (SEER). SEER is the seasonal cooling output measured in BTUs, divided by the seasonal energy input in watt-hours for an average U.S. climate. Since 2006, the national efficiency standard for central air conditioners require a minimum SEER of 13. An air conditioner requires a SEER of 14.5 or higher to qualify for Energy Star status.
