The next generation of air conditioning technology can reduce the amount of electricity used by cooling buildings and keeping people cool. With the rise in global temperatures, new air conditioning technologies need to be developed rapidly and at a scale that will not only keep people comfortable, but also limit the growth of greenhouse gas emissions. To meet this goal, the new technologies must be introduced to the market by 2022 and capture nearly 100 percent of the global air conditioning market by 2040.

The two main categories of air conditioners are packaged and split systems. Packaged systems have a condenser and compressor on the outside of the building, while split systems have their indoor and outdoor components in one unit. The main difference between these systems is their cooling capacity. A packaged system will cool more than one room at a time, and a split system will cool just one room.

The invention of air conditioning systems changed the way people worked and lived in the United States. It made it possible to work anywhere at any time of day, and it made it possible to live in the desert. The first air conditioned office building was built in the late 1920s. The early advertisements for air conditioning promised productivity and comfort.

When choosing an air conditioning system, it is important to understand your needs and budget. Typical BTU capacities for rooms with common temperatures range from 6,000 to 12,000 BTU. Choosing an air conditioner with the proper size will save energy and provide the best cooling.
