subject: Coping Without The Comfort Of An Air Conditioning Unit [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-conditioning is the method of controlling the state of air for a rather more cosy environment for man or commercial 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 required in aircon for the consideration of human comfort. Rather more exact control of these properties is necessary in the operation of some economic air-conditioning units. Other properties like odour and air pressure are further controlled in some explicit industries.
The control over air temperature in air con includes both cooling and heating processes. Aircon provides many applications. Air-conditioned business enterprises like stores, cafes and theaters attract shoppers particularly in the hot and humid high season. Modern transport needs sufficient aircon to provide folk with much needed comfort. Most modern buses, trains, aircraft and passenger automobiles are provided with state of the art air-conditioning systems that provide total comfort to the traveling public. Great business plants need accurate air temperature control to maintain their high level of product quality. Even business employees need a rather more favorable working environment and are sometimes supplied with business air-conditioning units, so as to function more efficiently and effectively in their operation.
Who must have started with the idea of air conditioning that we are reaping rewards from today? The cavemen, during prehistoric times, may have started the idea. The intense chill within the caves might have inspired them to come up with something which will make their lives more comfy. They discovered the 1st fire and used this to heat their caves. Moving fast forward, the successive development of temperature control over environment can be traced thru the discoveries in hearths, open fireplaces and ceramic stoves, but the arrival of modern air-conditioning has been accredited to Willis H. Carrier. Carrier described the energy relations that existed in an air and water vapour mix. To enable engineering designers to envision performance of the element parts, Carrier suggested some streamlining steps.
The development of both winter and summer air-con was mostly traced to the north Americans and along with this, were enhancements made in boilers, automated controls, instantly fired furnaces and thermal insulation.
Although the research work in home cooling was done in the 1930s, it wasn't until the late 1940s that the demands for home cooling systems became high. The Great Depression caused a delay in the public acceptance of the home cooling system because of the added burden of expenses the new system brought with it. Many homes were already equipped with air conditioning 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.
