Three-quarters of all homes in the US have an A/C unit. Air conditioning systems utilize about 6% of all the electricity produced in the United States, at an annual expense of about $29 billion to homeowners. As a result, roughly 117 million metric lots of co2 are released into the air each year.
Air conditioning unit use the very same operating principles and basic elements as your home refrigerator. Refrigerators utilize energy (typically electrical energy) to move heat from the cool interior of the refrigerator to the reasonably warm surroundings of your home; likewise, an air conditioning system utilizes energy to transfer heat from the interior of your home to the reasonably warm outside environment.
An air conditioner cools your house 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 normally made from 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 house. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outdoors air streaming over the condenser’s metal tubing and fins.
Throughout the 2nd half of the 20th century, nearly all ac system https://air-conditioning-edmonton.ca utilized chlorofluorocarbons (CFCs) as their refrigerant, however 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 likewise being gradually phased out, with a lot of production and importing dropped in 2020 and all production and importing dropped in 2030.
Production and importing these days’s main refrigerant for home air conditioning unit, HCFC-22 (likewise called R-22), started to be phased out in 2010 and will stop completely by 2020. Nevertheless, HCFC-22 is anticipated to be available for several years as it is recuperated from old systems that are gotten of service. As these refrigerants are phased out, ozone-safe hydrofluorocarbons (HFCs) are expected to dominate the marketplace, along air-conditioning-edmonton.ca with alternative refrigerants such as ammonia.
Changing to high-efficiency ac system and taking other actions to keep your house cool might lower energy usage for cooling by 20% to 50%.
