History Of Air-conditioner
In 1902 Sackett-Wilhelms, a publishing house at Brooklyn, was getting its printing all messed up. It was then that Willis Carrier was called upon to analyse the problem. He discovered that owing to fluctuations in heat and humidity paper dimensions kept changing, resulting in misalignment of coloured inks.
This was a classic temperature and humidity control problem. Carrier then invented the world’s first air-conditioning system. Carrier waited till 1906 before patenting this contraption of his, loosely termed as “an approach for treating air. It was the beginning of bigger thing for carrier.
He later went on to create the biggest air-conditioning firm which now a days operates globally with name of Carrier Aircon and has a market share of over the 40 % across the world.
Though now the market is flooded with a lot of players like National, LG, Samsung, Daikin, Blue Star, etc. and the technology has increased tenfold, this American giant MNC ( Carrier Aircon) and William Carrier will always be in the eyes of the world, simply because they were the ones who gave the world an industry which is worth billions over the global market and creates employment for millions of people.
Air-conditioner-The Product
An AC is primarily classified into three broad segments – unitary products, packaged air-conditioners (PAC) and ducted splits and central plants. The unitary products would include the window ACs and the mini-splits (without ducts).
Room air conditioners operate on electricity or gas and are enclosed in a single cabinet. They blow the conditioned air directly into the room and do not have air ducts leading to and from them.
Window air conditioners fit into the lower part of a window and can be moved from window to window and thus the name, Window ACs
Central air conditioners use electricity or gas. They can supply conditioned air to a number of rooms or to an entire building from one central source. Fans blow the conditioned air through air ducts from the air conditioner to the rooms. Central conditioners have a number of advantages over other kinds. For example, all the equipment for air conditioning a large area is located in one place. This reduces the cost of cleaning and repairing. Central conditioners can also be zoned i.e. they can supply air of different temperature to different parts of a building.
These ACs are ideal for rooms with low heat loads. They are available in the capacity range of 0.5 TR to 3 TR. The room AC sector caters to residential premises, offices and small establishments. Split ACs are so named because the unit is 'split' into two parts.
The compressor and the condenser forming an outdoor unit and the cooling coil remaining as an indoor unit. Split units can be with or without ducts. In PACs, the unit is placed in a separate room and the cold air is carried through ducting to the required areas. It is suited to those establishments that are not large enough to go in for a central system.
Ducted splits and PACs cater to segments requiring cooling capacity of less than 15 TR. The central air-conditioning segment is more technology intensive and project oriented. It caters mainly to institutional clients where capacity requirements are usually 50 TR and upwards.
The demand for nonducted products grew steadily in the latter half of the 1990s.The demand for mini-spilt ACs has grown at a higher rate as against window ACs mainly because of a lower base. The demand switch from mid sized ducted products, such as packaged ACs or ducted splits to mini splits is also one of the larger growth rates in the latter segment.
The demand for non-ducted products i.e. the window air conditioners & mini splits come from both households & corporate while the demand for ducted products comprising of the central plants & packaged air conditioners & ducted splits come only from corporate.
