New material set to change cooling industry

Refrigeration and air conditioning may become more efficient and environmentally friendly thanks to the patent-pending work of LSU physicists. The team of researchers led by LSU Physics Professor Shane Stadler has discovered ...

Research team develops wood-based foam to keep buildings cooler

Summertime is almost here, a time when many people try to beat the heat. But running air conditioners constantly can be expensive and wasteful. Now, researchers reporting in the ACS journal Nano Letters have designed a lightweight ...

Ancient pigment can boost energy efficiency

A color developed by Egyptians thousands of years ago has a modern-day application as well – the pigment can boost energy efficiency by cooling rooftops and walls, and could also enable solar generation of electricity via ...

NASA's first weather report from Jezero Crater on Mars

The weather often plays a role in our daily plans. You might put on a light jacket when the forecast calls for a cool breeze or delay your travel plans because of an impending storm. NASA engineers use weather data to inform ...

Plastic snowfall in the Alps

In a new study, Empa researcher Dominik Brunner, together with colleagues from Utrecht University and the Austrian Central Institute for Meteorology and Geophysics, is investigating how much plastic is trickling down on us ...

Introducing the i-Cool Solar air conditioning for trucks

(PhysOrg.com) -- A solar-powered air conditioning system has been developed for use in trucks, and should be available commercially by early 2012. The "i-Cool Solar" system was the brainchild of companies Mitsubishi Chemical ...

Air conditioning

Air conditioning refers to 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 mechanism 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, most commonly for comfort cooling in most buildings and motor-cars.

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.
