Why Changing to a Higher Performance A/C is a Wise Choice

Three-quarters of all homes in United States and Canada have an AC system. Air conditioning units utilize about 6% of all the electrical energy produced in the United States, at an annual expense of about $29 billion to homeowners. As a result, approximately 117 million metric tons of carbon dioxide are released into the air each year.

A/c utilize the same operating principles and standard elements as your home fridge. Fridges utilize energy (usually electrical energy) to move heat from the cool interior of the refrigerator to the fairly warm environments of your home; also, an air conditioning system uses energy to transfer heat from the interior of your house to the relatively warm outside environment.

An a/c cools your house with a cold indoor coil called the evaporator. The condenser, a hot outside coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded air-conditioning-edmonton.ca by aluminum fins. This tubing is normally made of 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 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, 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 used chlorofluorocarbons (CFCs) as their refrigerant, however because these chemicals are harming to Earth's ozone layer, CFC production stopped in the United States in 1995. Nearly all a/c systems now utilize halogenated chlorofluorocarbons (HCFCs) as a refrigerant, but these are also being slowly phased out, with many production and importing dropped in 2020 and all production and importing visited 2030.

Production and importing of today's main refrigerant for house air conditioners, HCFC-22 (also called R-22), began to be phased out in 2010 and will stop completely by 2020. However, HCFC-22 is expected to be available for many years as it is recovered from old https://air-conditioning-edmonton.ca systems that are gotten of service. As these refrigerants are phased out, ozone-safe hydrofluorocarbons (HFCs) are expected to dominate the marketplace, in addition to alternative refrigerants such as ammonia.

Switching to high-efficiency air conditioning system and taking other actions to keep your home cool might decrease energy use for air conditioning by 20% to 50%.
