Home air conditioning systems are responsible for a great deal of comfort in many parts of the world. However, it is not only cooling that home air conditioning systems provide, they can also purify air and heat it. Air conditioning and heating systems are often combined into one central aircon unit.
The term ‘air conditioning’, air con or simply AC refers to air quality, that is the cooling and dehumidification of indoor air for the thermal comfort of the occupants. However air conditioning systems have other applications too: for example many museums use AC to safeguard the quality of their documents. The American Declaration Of Independence is protected by aircon amongst other things.
However, in its broadest sense, air conditioning and heating can refer to any form of cooling, heating, ventilation, cleansing or disinfection that improves the air quality of the ambient atmosphere. An aircon system is, therefore, any appliance, system, or machine designed to stabilize the air temperature and humidity within an enclosed area. The enclosed area can be a home, a room or a box (in a museum).
Home air conditioning systems are generally thought to only refer to the cooling of air, but some models will also raise the temperature, if required, through the addition of a furnace. These system can make use of ducts or not.
The cooling cycle is usually carried out using a programmable refrigeration unit but sometimes using evaporation. Aircon systems are commonly used for comfort heating and air conditioning in residential buildings and motor vehicles with the aid of a thermostat.
The concept of residential AC equipment is known to have been applied in Ancient Rome, where water from an aqueduct would be circulated through the walls of the houses of the richest members of society in order to cool them.
Similarly, the homes of the rich and powerful in medieval Persia involved the installation of cisterns and wind towers to cool the buildings during the hot season.
However, our modern style electric home air conditioning systems are the result of advances in chemistry and electricity technology during the 19th century. The first large-scale electrical aircon household appliances were invented and used in 1902 by Willis Haviland Carrier.
Heat air conditioning can be thought of in two ways. Heat air conditioning can refer to systems that provide heating as well as cooling to maintain the air quality of a building or the term can refer to the method of cooling that the apparatus uses – heat transference products of high efficiency. Maintenance and Repairs are usually needed on older air conditioners as they age.
Central air conditioner prices depend on what type of air conditioning system you require and what you want to achieve with it. Obviously, it costs more to have an air conditioning unit that heats and purifies as well as cools. It is also more expensive to apply air conditioning to a larger area than a small one.
There are different types of central air conditioning systems. Some just cool, but others combine the functions of heating and cooling , so if you want to find out more about central air conditioning systems, look up that page on this web site.
Split air conditioning systems are those that have the distributor inside the room that has to be cooled and the fan, which is the noisier part of home air conditioning systems outside the room. The fan remains outside the building, which makes split air conditioning systems ideal for regulating domestic and office indoor air quality.
