With the summer fast approaching, a properly air condtioned, chilled, calm home is something everyone looks forward to at the end of the day, and most of us get stumped when this appliance, comes to a grinding halt due to a glitch. It usually takes hours to get a technician to come, check your appliance on a busy day, and might take days altogether after that, to get it repaired in case of a serious fault. So here are some tips to avoid this fateful condition, and to make sure your beloved air conditioner runs efficiently for a long time. 1) Insulation. Make sure your whole air conditioning system is properly insulated and leak proof. Check your walls for any air leaks that might affect the proper working of the air conditioner. Make sure all your windows are leak proof, and replace the heavily rusted parts of your window sills, if necessary. Also make sure you replace all the rusted and cracked parts of metal in your air conditioner units. This also includes the duct lining and the other parts of the air conditioner that might be present outside the building. 2) Maintenance and Servicing. Have your air conditioner serviced by a professional atleast once every six months. A professional can check the direction of air flow, inspect the coils and assess its efficiency. And make sure you have a proper, clean surrounding for the appliance. Dusty surroundings can not only reduce the efficiency of the air conditioning unit, but also cause problems like asthama, wheezing and other air-borne, particle-spread diseases. 3) Placement. Make sure the air conditioner unit’s registers are not covered. This includes window curtains and hanging plants too. Ideally, the curtains should be held about 25cms above your unit, in case of a window type air conditioner. Incase of a seperate heat rejecting unit, like in the case of a portable type and split type, make sure the heat rejecting unit is not kept in direct exposure of sunlight. Use curtains to block the heat and sunlight into the room during the hottest part of the day. This not only prevents unnecessary heat accumulation in your room, but also keeps your cooling appliances clean. 4) Chemical Cleaning. Use chemical cleaning to clean the insides of your coils. Removing the dust accumulation on the coils helps air flow, and reduces problems in the long term. Most importantly, avoid vaccuming the coils, because this causes serious health problems.
A modern day air conditioning unit
Air conditioners are considered by many to be life savers that help us fight the scorching summer heat. Not only do they cool the air in our buildings and provide us with a chilled room, but they also have numerous health benefits. Air conditioners contain filters that purify the air we breathe and remove all the dust, the dirt, the microbial particles present and all other air borne particles that are almost inseparable.
Air conditioners also have stress reducing qualities that are even lesser known. Hot air has very high stress inducing qualities, which causes an increase in blood pressure, increased heart rate and also cause nervous break downs in extreme conditions. Air conditioners are known to be able to effectively counter all these issues which are known to wreck our summers for us. But how did this magic appliance come to be?
John Gorrie – the physicist who made the breakthrough
There were many attempts at this kind of device right from mid-18th century. The first notable moment came when Dr. John Gorrie, an American physician, made a machine that blew air, using many wall fans, over a bucket containing crushed ice.
Perhaps the first break-through was achieved by Willis Carrier. Widely acknowledged to be the “Father of Air Conditioning”, his machine was called “Air Treatment Machine”, and used chilled coils to cool the air. This apparatus was able to lower the humidity to almost 50%.
The major drawback of this apparatus was its huge and bulky size, and the use of poisonous ammonia as a coolant. This problem was overcome eventually in 1922, when Carrier replaced the ammonia with benign coolant dielene, and a compressor was added to the system. But the apparatus still remained very bulky and noisy for use in home. By 1928, air conditioners were installed in the offices of all the representatives in the White House, and soon the Supreme Court and the Senate followed suit.
After the second World War, the sale of air conditioners increased by almost ten times in less than 8 years.
Today, while the air conditioners are widely blamed for the burning of a huge hole in our ozone layer, it has become one of the essentials of life, right after food, water and shelter, and cannot be done without.
