What’s It All About
Two-thirds of all homes in the United States have an air conditioner. A heating and air conditioner use about 5% of all the electricity produced in the United States, at an annual cost of more than $11 billion to homeowners. As a result, roughly 100 million tons of carbon dioxide are released into the air each year — an average of about two tons for each home with an air conditioner.
A heating and air conditioner employs the same operating principles and basic components as your home refrigerator. Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings of your home; likewise, an air conditioner uses energy to transfer heat from the interior of your home to the relatively warm outside environment. To keep your air conditioner running efficiently, it;’s crucial to schedule routine air conditioning maintenance.
A heating and air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils.
The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and cooling your home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser’s metal tubing and fins.
Throughout the second half of the 20th century, nearly all air conditioners used chlorofluorocarbons (CFCs) as their refrigerant, but because these chemicals are damaging to Earth’s ozone layer, CFC production stopped in the United States in 1995. Nearly all air conditioning systems now employ halogenated chlorofluorocarbons (HCFCs) as a refrigerant, but these are also being gradually phased out, with most production and importing stopped by 2020 and all production and importing stopped by 2030.
Production and importing of today’s main refrigerant for a home heating and air conditioner, HCFC-22 (also called R-22), began to be phased out in 2010 and will stop entirely by 2020. However, HCFC-22 is expected to be available for many years as it is recovered from old systems that are taken out of service. As these refrigerants are phased out, ozone-safe hydrofluorocarbons (HFCs) are expected to dominate the market, as well as alternative refrigerants such as ammonia.
Switching to a high-efficiency air conditioner and taking other actions to keep your home cool could reduce energy use for air conditioning by 20% to 50%.
The two most common types of air conditioners are a room heating and air conditioner and a central heating and air conditioner. A compromise between the two types of systems is provided by a ductless, mini-split air conditioner.- Energy.gov
