Welcome to airconditionmission3.com where you can find all things related to the world of Air Conditioners. Air conditioning. What a lifesaver. It has made the suburbs possible. Manufacturing from the north to the south occurred because plants could be built and people could work in them without collapsing from the heat. Its cost at one point, however, drew one scientist, William Schockley the co-inventor of the transistor, to move his research facilities to California, to what later became known as Silicon Valley. There he did not have to put air conditioning in his building. Even when air-conditioning was purposely avoided, it had an impact.

So it started out as a way of making people comfortable. Right? Well, not exactly. In 1882, thanks to Thomas Edison, the first electric power plant opened in New York making it possible for the first time to have an inexpensive source of energy for residential and commercial buildings. And by 1889, central station refrigeration was used in large cities to preserve foods and documents. It was well known that a cool surrounding could preserve foods and other perishables for a long time. But what was not well known was how humidity and heat were related. Then in 1902, Willis Carrier built the first air conditioner to combat humidity inside a printing company. Controlling the humidity in printing companies and textile mills was the start of environment management.

  
  
Tips for Lowering Your Central Air Conditioner's Energy Usage

02/07/12

Set your thermostat at 78 F or higher. Each degree setting below
78 F will increase energy consumption by approximately 8%. Be
careful, however, that if you're A/C is oversized the diminished
run-time from raising the thermostat setting may result in
too-high indoor humidity in some locations.

Use bath and kitchen fans sparingly when the air conditioner is
operating to avoid pulling warm, moist air into your home.

Inspect and clean both the indoor and outdoor coils. The indoor
coil in your air conditioner acts as a magnet for dust because
it is constantly wetted during the cooling season. Dirt build-up
on the indoor coil is the single most common cause of poor
efficiency. The outdoor coil must also be checked periodically
for dirt build-up and cleaned if necessary.

Check the refrigerant charge. The circulating fluid in your air
conditioner is a special refrigerant gas that is put in when the
system is installed. If the system is overcharged or
undercharged with refrigerant, it will not work properly. You
will need a service contractor to check the fluid and adjust it
appropriately.

Reduce the cooling load by using cost-effective conservation
measures. For example, effectively shade east and west windows.
When possible, delay heat-generating activities, such as cooking
and dishwashing, until evening on hot days.

Over most of the cooling season, keep the house closed tight
during the day. Don't let in unwanted heat and humidity.
Ventilate at night either naturally or with fans.
