Cooling A warming Planet: Part 1

Artificial cooling has had a profound effect on how, and where, we live and work

 Did you know?

  • Air Conditioning is the control of not just the temperature but the humidity, the air quality and the air flow in a space.
  •  In 1902, Willis Carrier patented the air conditioner, a device that would impact factory productivity, building design, population trends, and, ultimately, the growth of cities.
  •  When a national group of urban planning historians was asked to rank the most important influences on the American metropolis in the last half of the 20th century, their top 10 list focused on social, economic and political developments. Of the many technological devices that helped shape our lives during that era, only two made the list: the automobile and the air conditioner.
  • A 2008 National Bureau of Economic Research study concluded that in the era of air conditioning, the general tendency of hot weather to depress economic activity no longer affects the world’s wealthier nations.
  • Air conditioning applications are broadly divided into comfort and process  applications.
  • Process applications aim to provide a suitable environment for a process being carried out such as Hospital operating theatres, in which air is filtered to high levels to reduce infection risk and the humidity controlled to limit patient dehydration.,  Clean rooms for the production of integrated circuits, pharmaceuticals, and the like, in which very high levels of air cleanliness and control of temperature and humidity are required for the success of the process ,Facilities for breeding laboratory animals,Data centers, Textile manufacturing, Nuclear power facilities, food cooking and processing areas,chemical and biological labs.
  • Comfort applications aim to control indoor environment in buildings such as residential buildings, malls, shopping centers, restaurants, transportation applications such as vehicles, trains, ships, aircraft, and spacecrafts and  sports stadiums such as the  Qatar stadium for the 2022 FIFA World Cup
  •  Refrigerants are the key to air conditioning and refrigeration, but they can also be serious troublemakers when released into the atmosphere.
  •  The chlorofluorocarbons (CFCs) used in its air conditioners refrigerants are blamed for the growing hole in the Earth’s ozone layer
  •  Under the 1989 Montreal Protocol Refrigerants such as chlorofluorocarbons (CFCs) that harm the stratospheric ozone layer are being phased out.

The world is warming, incomes are rising, and economies are booming, one result of this is a booming market for air conditioning — world sales in 2011 were up 13 percent over 2010, and that growth is expected to accelerate in coming decades.

As demand increases in the world’s warmer regions, global energy consumption for air conditioning is expected to continue to rise dramatically and could have a major impact on climate change.

The big question is this, how do we strike a balance?
