Detailed Explanation of Air Conditioning
Air Conditioning is a method of providing clean air to an area at the proper temperature and humidity. The term usually describes a refrigeration system designed to cool the air within a space. In the process of removing heat, the system also removes moisture from the air, further increasing comfort levels. Auxiliary filters may remove pollen, dust and other such pollutants from the air. Entire buildings are designed so that air temperature, humidity, and freshness are controlled by a single, central air conditioner. There are many different types of air conditioner, and of all these types’ people in the UK are mostly familiar with the type known as a “split system”. This is an indoor fan coil unit connected via pipe work to an outdoor condensing system.
The key element of the air conditioner is the refrigerant, most often a fluorocarbon that flows constantly through the conditioners mechanisms. Becoming a liquid and giving off heat when it is compressed, and becoming a gas and absorbing heat when that pressure is removed. The mechanisms that evaporate and compress the refrigerant are divided into two areas, an indoor air filter fan and cooling coil. And outdoor comprising of a compressor, condenser coil and fan.
In the air cooling cycle, warm humid air is drawn from the room through the filter and over the cooling coil. This coil contains a refrigerant fluid with a very low boiling point, i.e. it will have evaporated at room temperature. The warm air gives up its heat to the refrigerant and in the process, causes the refrigerant to vaporize. Cooled dehumidified air is blown back into the room. The vaporized refrigerant moves to the compressor, which pumps it under pressure to the condenser coils.
Here its heat is transferred by fan to the outside, and it is returned to the cooling coil as a liquid. Electric motors drive the compressor, blower and fan. A thermostat controls the compressor motor, turning it off when the room temperature reaches the desired level and restarting it as the room heats up.
Buildings can be centrally air conditioned if they have a forced air conditioning system, which uses a blower fan and ducts to distribute heated or cooled air throughout the building. During the summer months these ducts can be used to carry cooled air. In most central air conditioning units, the condenser and compressor are built into an enclosed housing outdoors, and the cooling coil is mounted in the main duct near the blower fan. Insulated tubing is used to carry the refrigerants between components.
A large building may have one or more cooling units mounted on its roof or placed beside it. In some units, a fresh air intake mixes fresh outside air with the inside air. This mixture is pushed through several filters that remove polluting airborne particles. The cleaned air is then cooled as it passes over the coils of a large cooling unit. Where the air is too dry and needs added moisture, it may be forced through ducts containing a fine water spray. Finally the cooled air passes into the rooms or offices in the building.
Indoor units come in various shapes and sizes to suit the particular environment. They can be located on the floor, on a wall, or below or within the ceiling. The size of the indoor unit normally reflects the capacity i.e. the amount of cooling or heating. Outdoor units generally look the same although varying in size. If there is no available external location, the outside unit can be positioned adjacent to an outside wall and a hole cut to vent the system.
Primitive 19th century air conditioning systems used the evaporation of blocks of ice to cool the air. Credit for the first practical air conditioning system is generally given to the American inventor Willis Carrier, who designed a mechanical air conditioner in 1911 and began manufacturing conditioners in 1915.
It was not until the 1930′s however, that air conditioning systems began to be installed in office buildings, hospitals, apartments, trains and buses. By 1950, air conditioning had also become an option on most vehicles. Today, many large buildings are constructed with air conditioning. Most large systems are controlled by computers to ensure efficient interaction between the environment and the conditioning and heating systems.
