Three-quarters of all homes in North America have an air conditioning system. Air conditioning systems utilize about 6% of all the electrical air-conditioning-edmonton.ca power produced in the United States, at a yearly cost of about $29 billion to homeowners. As a result, roughly 117 million metric tons of carbon dioxide are released into the air each year.
A/c use the very same operating principles and standard parts as your house refrigerator. Refrigerators use energy (normally electrical power) to move heat from the cool interior of the fridge to the relatively warm environments of your house; also, an a/c unit uses energy to transfer heat from the interior of your house to the relatively warm outside environment.
An air conditioning system cools your house with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, launches the collected 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 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, quiting its heat to the outside air streaming over the condenser's metal tubing and fins.
Throughout the 2nd half of the 20th century, nearly all a/c utilized chlorofluorocarbons (CFCs) as their refrigerant, however since these chemicals are harming to Earth's ozone layer, CFC production stopped in the United States in 1995. Nearly all air conditioning systems now utilize halogenated chlorofluorocarbons (HCFCs) as a refrigerant, however these are likewise being slowly phased out, with many production and importing stopped by 2020 and all production and importing come by 2030.
Production and importing these days's main refrigerant for home air conditioning unit, HCFC-22 (likewise called R-22), began to be phased out in 2010 and will stop completely 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 out, ozone-safe hydrofluorocarbons (HFCs) are expected to dominate the https://air-conditioning-edmonton.ca/ marketplace, in addition to alternative refrigerants such as ammonia.
Changing to high-efficiency air conditioners and taking other actions to keep your house cool might lower energy use for a/c by 20% to 50%.
