Why Changing to a Higher Efficiency AC System is a Smart Choice
Three-quarters of all homes in North America have air conditioning units. Air conditioning systems utilize about 6% of all the electrical power produced in the United States, at an annual expense of about $29 billion to homeowners. As a result, approximately 117 million metric lots of carbon dioxide are released into the air each year.
Air conditioning unit utilize the exact same operating principles and basic components as your house fridge. Fridges use energy (typically electrical energy) to move heat from the cool interior of the fridge to the relatively warm surroundings of your home; also, an a/c uses energy to transfer heat from the interior of your house to the relatively warm outside environment.
An a/c unit cools your home with a cold indoor coil called the evaporator. The condenser, a hot outside coil, launches the gathered heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is generally made from copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump requires the refrigerant through the circuit of tubing and fins in the coils.
The liquid refrigerant vaporizes in air-conditioning-edmonton.ca 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, quiting its heat to the outside air flowing over the condenser's metal tubing and fins.
Throughout the 2nd half of the 20th century, nearly all air conditioning system used chlorofluorocarbons (CFCs) as their refrigerant, but because these chemicals are harming to Earth's https://air-conditioning-edmonton.ca/ ozone layer, CFC production stopped in the United States in 1995. Nearly all cooling systems now use halogenated chlorofluorocarbons (HCFCs) as a refrigerant, however these are also being gradually phased out, with the majority of production and importing dropped in 2020 and all production and importing visited 2030.
Production and importing these days's main refrigerant for home a/c unit, HCFC-22 (also called R-22), started to be phased out in 2010 and will stop totally by 2020. However, HCFC-22 is expected to be offered for several years as it is recuperated from old systems that are taken out of service. As these refrigerants are phased https://air-conditioning-edmonton.ca out, ozone-safe hydrofluorocarbons (HFCs) are anticipated to dominate the marketplace, along with alternative refrigerants such as ammonia.
Switching to high-efficiency air conditioning system and taking other actions to keep your house cool might minimize energy usage for air conditioning by 20% to 50%.
