subject: Can You Handle Life Without Air Conditioning? [print this page] Can you survive the freezing winter days and nights without your heater on? Can you imagine the hot summer months without your air cooling system running all day long? If you can't, you might want to thank the person who invented the air conditioning system. He made our lives easier and more comfortable.
Air con is the method of controlling the disposition of air for a rather more snug environment for man or business products. 4 characteristics of air are controlled in aircon. These are air temperature, relative humidity, air motion or circulation and the dust particles in air. A control over these 4 properties is mandatory in air conditioning for the consideration of human comfort. Much more accurate control of these properties is necessary in the operation of some business air-con units. Other properties like odour and air pressure are further controlled in some categorical industries.
The control over air temperature in air con includes both cooling and heating processes. Aircon provides many applications. Air-conditioned business establishments like stores, restaurants and theaters attract buyers particularly in the hot and damp high season. Modern transport requires sufficient air-con to provide folks with sorely needed comfort.
Most modern buses, trains, aircraft and passenger vehicles are provided with state of the art air-con systems that provide total comfort to the traveling public. Big business plants need exact air temperature control to maintain their high level of product quality. Even economic workers need a favorable working environment and are customarily supplied with business aircon units, to function more efficiently and effectively in their operation.
Who must have started with the idea of air con that we are reaping rewards from today? The cavemen, during prehistoric times, might have started the concept. The acute chill within the caves might have pushed them to come up with something which will make their lives more comfy. They discovered the first fire and used this to heat their caves. Moving fast forward, the successive development of temperature control over environment can be traced thru the advancement in hearths, open fireplaces and ceramic stoves, but the arrival of modern air-con has been assigned to Willis H. Carrier. Carrier described the energy relations that existed in an air and water vapor mix. In order to enable engineering designers to foretell performance of the part parts, Carrier suggested some streamlining steps.
The development of both winter and summer aircon was principally assigned to the Americans and with this, were enhancements made in boilers, automatic controls, automatically fired furnaces and thermal insulation.
Though the research work in home cooling was done in the 1930s, it was not till the late 1940s the demands for home cooling systems became high. The Great Depression caused a delay in the general public approval of the home cooling system thanks to the added burden of costs the new system brought with it. Many houses were already provided with aircon by 1950s and 1960s. Obviously , the development of the air-con system has brought so much comfort to day-to-day lives and favorable environments to our ever-growing industries.
