Air Conditioning

In ordinary conversation, when the word air conditioning is stated, people automatically take it to mean cooling room temperature. Technically speaking, though, air conditioning is the process of controlling room temperature through various means that involve ventilation, heating system and cooling. In structure, it is referred to as HVAC. Aircon Services Singapore

In 1902, The New York Share Exchange was the very first building to use air conditioning units that separately cooled and warmed up the environment. Later that 12 months, Willis Havilland Carrier installed the earliest electrically-run air fitness unit at a printing photos plant. The unit not only cooled the air but also handled the humidity. 

In those times, air conditioning was generally used in manufacturing facilities to boost products by handling the associated with humidness, thus, increasing employee production. It was several years later, in the 1955s, that homes and autos started to be when you have the air conditioning technology.

An air conditioning unit cools the air by using a refrigerant, a substance that alters the temperature of the air. In the early stages of the development, air conditioning models used harmful gases such as ammonia and methyl chloride as refrigerants. They will were soon replaced by another type of substance, patented substance called Freon.

Freon is safe for humans. Nevertheless , it is harmful to the surroundings. The moment released into the atmosphere, this chlorofluorocarbon gas is believed to be a contributing factor to the thinning of the ozone layer. Most air AC sold today still employ this type of gas, specifically the HCFC R-22. That is said that environment activists will have to hang on until 2010 to find the total eradication of HCFC R-22 in air conditioning untis.

Air health and fitness units have different types of refrigeration cycles. The first type uses a heat pump that hard disks out heat from the room and blows in cooled air though a compressor. The second type pumps in a refrigerant. If the refrigerant evaporates, it takes with it the hot air and leaves cooled air.
