Three-quarters of all homes in the USA and Canada have an air conditioning system. Air conditioning units use about 6% of all the electrical power produced in the United States, at a yearly cost of about $29 billion to property owners. As a result, approximately 117 million metric lots of carbon dioxide are released into the air each year.
Air conditioners employ the exact same operating principles and fundamental parts as your home fridge. Refrigerators use energy (normally electrical power) to move heat from the cool interior of the refrigerator to the reasonably warm environments of your home; similarly, an a/c utilizes energy to transfer air-conditioning-edmonton.ca heat from the interior of your house to the relatively warm outside environment.
An a/c cools your home with a cold indoor coil called the evaporator. The condenser, a hot outside coil, launches the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is typically made of copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) in https://air-conditioning-edmonton.ca/ between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils.
The liquid refrigerant vaporizes 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 flowing over the condenser's metal tubing and fins.
Throughout the 2nd half of the 20th century, nearly all air conditioning system 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 use halogenated chlorofluorocarbons (HCFCs) as a refrigerant, but these are also being slowly phased out, with the majority of production and importing visited 2020 and all production and importing dropped in 2030.
Production and importing these days's primary refrigerant for home ac system, HCFC-22 (likewise called R-22), started to be phased out in 2010 and will stop totally by 2020. Nevertheless, HCFC-22 is expected to be readily available for many 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 market, along with alternative refrigerants such as ammonia.
Switching to high-efficiency ac system and taking other actions to keep your home cool might lower energy usage for cooling by 20% to 50%.
