Air conditioning is the cooling and dehumidification 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.

The central air conditioning in my apartment is getting repaired and won't be working for 4 or 5 days. I want to improvise something. Maybe taking a fan and pointing it a a bag of ice. Heck.. I don't know... Any tips ? Asked by lambcrawler - Fri Jun 8 20:34:42 2007 - - 5 Answers - 0 Comments A. use the principle of evaporation. Depending on the humidity, it can work wonders. Lightly soak and wring out a sheet before bed, and have a fan blow across you. You will be comfortable enough to get to sleep. Some people get a large amount of ice, put it in a shallow pan, and have a fan blow over it. Another is to fill an ice chest with 70% ice and 30% water, take a hand towels, soak and wring out, then place over head and breathe the cold air. Do it once more but this time leave on your wrists for a couple of minutes. As for a whole house fix, there is no other DIY method I know of. The ice cold towel on the head is really amazing relief even though temporary.
