Air conditioning is the cooling of indoor air for thermal comfort. In a broader sense, the term can refer to any form of cooling, heating, ventilation, or disinfection that modifies the condition of air. An air conditioner (often referred to as AC or air con.) is an appliance, system, or machine designed to stabilise the air temperature and humidity within an area (used for cooling as well as heating depending on the air properties at a given time), typically using a refrigeration cycle but sometimes using evaporation, commonly for comfort cooling in buildings and motor vehicles. The concept of air conditioning is known to have been applied in Ancient Rome, where aqueduct water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier.

About four months ago my air conditioning stopped working. By that, I mean that it would blow air, but the air wouldnt be cold. Then yesterday my heater stopped working in the same way, so now my car blows the same temp air out the vents regardless of the setting. Any help narrowing down the source would be great! Asked by Jennifer K - Wed Apr 4 00:07:59 2007 - - 2 Answers - 0 Comments A. The A/C problem and the heater problem are probably not related... but could be. They are both electrically controlled by the HIVAC control head. The cause of your A/C not blowing cold could be caused by alot of different things. The lack of heat also. On your lack of heat issue... There is something simple that you yourself may be able to check, that is, your coolant level in the radiator. If your coolant level is low (from a leak) there may not be enough coolant to circulate through the heater core and this may be the cause of your lack of heat. Make sure the engine is cold before attempting to check or have anyone else check the coolant level. If the coolant level is low you will need to have the source of the leak fixed. Answered by know da stuff - Wed Apr 4 00:26:40 2007 Who can tell me about air conditioning parts or lead me to a good diagram? Q. We are trying to fix the air conditioning at work (the landlord won't do anything) and need to replace some parts. We have the ducts and I have found out that the ducts are connected to the collars (male/female). The collars are then attached to a big square piece which then has the grille attached where the air goes out. Does anyone know what the big metal square piece is called? I've been looking online but so far, no luck. And if you know of any good diagrams illustrating this, that'd be great as well. Thanks!

Q. I live in a very old house which for some reason makes it very hard to install air conditioning (it has something to do with the thin walls) so any cool air we have comes from fans. This however does not do the best job of keeping the house cool. Is there anything I can do to keep my house cool when it's hot? Asked by Ro - Fri May 25 18:37:53 2007 - - 16 Answers - 1 Comments A.
