Air conditioning (often referred to as aircon, AC or A\/C) is the process of altering the properties of air (primarily temperature and humidity) to more favourable conditions, typically with the aim of distributing the conditioned air to an occupied space to improve comfort. In the most general sense, air conditioning can refer to any form of technology, heating, cooling, de-humidification, humidification, cleaning, ventilation, or air movement, that modifies the condition of air.<\/p>\n\n\n\n
In common use, an air conditioner is a device (most commonly a home appliance or automobile system) that lowers the air temperature. The cooling is typically done using a simple refrigeration cycle, but sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles. In construction, a complete system of heating, ventilation and air conditioning is referred to as “HVAC”.<\/p>\n\n\n\n
Air conditioning can also be provided by a simple process called\u00a0free cooling\u00a0which uses pumps to circulate a coolant (typically water or a glycol mix) from a cold source, which in turn acts as a\u00a0heat sink\u00a0for the energy that is removed from the cooled space. Free cooling systems can have very high efficiencies, and are sometimes combined with\u00a0seasonal thermal energy storage\u00a0(STES) so the cold of winter can be used for summer air conditioning. Common storage media are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat exchanger equipped boreholes. Some systems with small storage are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the temperature of the storage gradually increase during the cooling season, thereby declining in effectiveness. Free cooling and hybrid systems are\u00a0mature technology.<\/p>\n\n\n\n
