Air conditioning, often abbreviated as A/C (US) or air con (UK), [1] is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical ...

, = 42 °C – [(42 °C – 19 °C) × 85%] = 22.45 °C or 72.41 °F. However, either of two methods can be used to estimate performance: Use a psychrometric chart to calculate wet bulb temperature, and then add 5–7 °F as described above.
Refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated because of their toxicity and flammability [ 1 ] and the contribution of CFC and HCFC ...
Jorge Bacerra takes a drink of water from a bottle in his vest as the temperature reaches 106 degrees along Weber Avenue near Roeding Park in September 2022.
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...

Temperature in each zone may be adjusted by adding small amounts of trim air, which is low-pressure, high-temperature air tapped off the AC PACK upstream of the TCV. Air is also supplied to individual gasper vents. [a] A revolving control on the vent can be turned to adjust ventilation between no air output at all and a fairly substantial breeze.
