Some of the air conditioners are placed in windows while others are split type and ceiling type. There are also some electric fans which are equipped to provide coolness to a small room. Almost all of the types have condensers which actually work to provide the coolness. A fan or blower is also integrated into the machine in order to blow out the cold air and bring it to the people in the area.
The main advantage of having an air conditioner in the room or area is the coolness that it brings. There are several months in a year that may be so hot that people resort to different things just to cool down. Having air conditioning equipment is a boon for those in the house or area. Many people often go to malls just to cool down and feel better from the heat outside. Another advantage, apart from the comfort that these machines bring, is the well-being and health of the individual. Small children and the elderly easily suffer from heat stroke because they have a difficult time regulating their bodies. It is important to keep them cool when the temperature rises above normal and brings about a hot day. Many of those who suffer from heatstroke may pass away because they cannot cool down. Aside from the health, comfort and well-being of people, plants and animals also benefit from the chill that these kinds of equipment bring. Some plants wilt or die from extreme heat and they can benefit from being under a shade or better yet placed in a room which has a decidedly lower temperature due to the efforts of air conditioning. The same goes for animals and pets that may be left outside in the heat of the sun. Many long haired dogs and cat need to be kept cool when the temperature is too high for comfort. Food also spoils less fast when placed in an air conditioned room. Some art objects also need to be kept in a regulated room in order for these not to be affected by the heat. This is especially true for paintings.
Air conditioning also has some disadvantages. Many experts believe that constantly going into a cool room and out to the hot outside can cause some respiratory illnesses. Some suffer from migraines if they constantly move in and out of a cool room to the warm outside. Some sicknesses can also be transmitted easily if the individuals are always in a closed air conditioned room. The air inside such a room just circulates and is not usually refreshed unless the windows are opened to let in fresh air and circulate the air inside.
