Air-conditioner sales get a boost in Goan summer

The sale of air conditioners in Goa has risen exponentially  in the past couple of months as citizens try to desperately beat the heat in Goa by resorting to cool down the temperatures in offices, shops and homes in Goa through the use of cooling systems.

So traders in Goa who normally sell around five air conditioners per month are now selling around 30 per month thanks to the increased humidity in the state in the month of April and May this year. Also air cooler units blowing cool air, have also seen robust sales this year thanks to the heat in Goa and traders are on song selling a record number of air-coolers in Goa this year.

The popular brands of air-conditioners in Goa range in prices from Rs 16,000 to around 47,000 depending on the type of brand and the capacity. However the 1 tonne and the 1.5 tonne air conditioners are reportedly very popular owing to their mid range size. The brands available in the Goan market are Samsung, Hitachi, LG, Onida, Daikin, Godrej, Blue star , General and Voltas.

It is also notable that the modern air conditioners sold in Goa consume lesser electricity for its use compared to the older models sold a few years back due to which the general public prefers to use an air conditioner compared to earlier trends.

The older generation of airconditioners employed toxic or flammable gases like ammonia, methyl chloride and propane. The usage of such gases could result in fatal accidents when they leaked. In the year 1928, Thomas Midgley Jr, created the first Chlorofluorocarbon gas, Freon, which was much safer for human beings but was later found to be harmful to the ozone layer of the atmosphere.

The blend mostly used in homes and buildings was an HCFC known as R-22. But it is to be phased out for use in new equipment by 2010 and completely discontinued by 2020.

However several non ozone depleting refrigerants have been developed as alternatives including R-410A, known by the brand name of Puron.

Room air-conditioners normally come in two forms or constructions. Unitary and split or packaged terminal PTAC systems. Unitary systems or the common one-room air conditioners sit in the window or wall opening with interior controls. Interior air is cooled as a fan blows it over the evaporator. On the exterior, the air is heated as a second fan blows it over the condenser.

The split AC ( PTAC) on the other hand is frequently used in offices, shops and hotels. It has two separate units ( terminal packages) , the evaporative unit on the exterior and the condensing unit on the interior with tubing passing through the wall and connecting them. This minimises the interior system footprint and allows each room to be adjusted independently.

So how does a Goan make a choice about what kind of AC he should fit in his house , shop or office. here is some advice.

If you want a nice neat look in your premises, the Split AC is a good option. Also if you didn't want to mess with the window, split would be a good idea. Besides if you don't like the external of a window AC hanging out, a split may be a prudent decision. Also the compressor of the split can be located at a far distance through tubing. However if tubing and compressor for split is a problem then surely Window AC is the way to go.

Split AC is also expensive on the budget and you may want to look at that too before making a decision. Window ACs are cheaper and 
subject to the above, both AC's have similar functions in operations and makes no difference to comfort levels.
