Split air conditioners offer more advantages<\/p>\n
Living in a country like Indonesia that has a tropical
\nclimate, an air conditioner is a virtual necessity for
\nhomeowners.<\/p>\n
First introduced and patented by Willis Carrier of the U.S. in
\n1906, air conditioners are now available in all different types
\nand sizes.<\/p>\n
The cost and efficiency of home air-conditioning systems
\nvaries. Basically, there are four types of air conditioners
\navailable in the market these days. They include the window unit,
\nbuilt-in window, central air-conditioning and the ductless split
\nsystem.<\/p>\n
The window unit is generally easy to install in any standard
\ndouble-hung window, while the built-in window is an air
\nconditioner unit that is installed into the wall.<\/p>\n
Although built-in units normally consume more energy than
\nwindow units, they offer more features like cool\/heat selections,
\naccording to a buying guide at www.air-conditioners-advice.com<\/p>\n
Central air-conditioning cools several rooms simultaneously
\nthrough your home's ducts, but some systems can be noisy.<\/p>\n
Duct-free split systems, or Split AC as they are commonly
\ncalled, require professional installation, but this type of air
\nconditioner offers silent, duct-free air-conditioning, which
\nmakes it quite suitable for home use.<\/p>\n
Split ACs are quite popular in Asia, including Indonesia. The
\nSplit AC comprises an indoor unit and outdoor unit. In fact, the
\nSplit ACs dominate the country's air conditioner market.<\/p>\n
The cooling capacity of an air conditioner is measured in
\nBritish Thermal Units (BTUs) -- the amount of the heat that is
\nprocessed per hour in the air conditioner.<\/p>\n
Generally, the split air-conditioning systems sold in
\nIndonesia have different sizes, including 0.5 PK (horsepower),
\n0.75 PK, 1 PK, 1.5 PK and 2.5 PK.<\/p>\n
An air conditioner with 1 PK has the cooling capacity of 9,000
\nBTUs. For home use, the standard is 600 BTUs for each square
\nmeter. This means that a 1 PK air conditioner can cover a room
\nthe size of 15 square meters.<\/p>\n
The most popular brands in the Split AC category in the
\nIndonesian market are LG, Samsung, Panasonic, Sharp, Fujitsu and
\nDaewoo. The standard size is between 0.5 and 1 PK and they sell
\nfor between Rp 1.6 million and Rp 2.5 million each.<\/p>\n
Advantages<\/p>\n
According to the U.S. Environmental Protection Agency,
\nductless split air conditioners have numerous residential and
\ncommercial applications.<\/p>\n
The most common residential applications are in multifamily
\nhousing or as retrofitted add-ons to houses with hydronic or
\nother non-ducted distribution systems (radiant panels, wood
\nstoves, etc.).<\/p>\n
Installation in new additions, where extending or installing
\nductwork is not feasible, is also a popular application.
\nCommercial uses are also numerous. Some applications include
\nschools, perimeter cooling for office buildings, additional
\ncooling for restaurant kitchens and cooling for small offices
\nwithin larger spaces, such as arenas, warehouses and auditoriums.<\/p>\n
Ductless split-system air conditioners combine the zoning
\nflexibility of a conventional room unit (a single air conditioner
\ninstalled through a wall or a window frame) with the whole-house
\ncooling potential of central systems.<\/p>\n
Like central systems, they have two main components: a
\ncompressor\/condenser, as well as an air handling unit, which
\ncontains an evaporator and a fan.<\/p>\n
Some units operate as heat pumps and provide both summer
\ncooling and winter heating. The noisy compressor and condenser
\nare housed as one unit and located outdoors. The quiet
\nfan\/evaporator unit is indoors, located in the area to be cooled.<\/p>\n
A conduit, which houses the power cable, refrigerant tubing,
\nsuction tubing and condensate drain, links the outdoor and indoor
\nunits. The term, \"split-system,\" also describes some central air
\nconditioners and heat pumps. If you ask about ductless, split-
\nsystem air conditioners, make sure the dealer understands which
\nsystem you are talking about.<\/p>\n
Another common term for ductless split-systems is \"mini-
\nsplits\".<\/p>\n
The advantages of ductless split-systems over room and central
\nair conditioners are: easy installation, quiet operation,
\nversatility in zoning and design, and security, EPA says in its
\nconsumers guide posted at online airconditioner shop
\nwww.iapcooling.com.<\/p>\n
The split systems also eliminate the loss of cool air as it
\npasses through the ductwork. A key advantage of split systems is
\ntheir ease of installation.<\/p>\n
Hook-up requires only a 7.62-centimeter hole in the wall for
\nthe conduit. Unlike with central air-conditioning, you do not
\nneed ductwork. Since the compressor in most ductless split-
\nsystems is as much as 15.24 meters away from the indoor
\nevaporator, it is usually possible to cool rooms on the front
\nside of the house, while still hiding the compressor in a less
\nconspicuous area.<\/p>\n
The compressor units also fit well on flat commercial building
\nrooftops. Ductless split-system air conditioners operate
\nrelatively quietly, since the compressor is outside and the
\nevaporator unit's fan generally runs at a low speed.<\/p>\n
Variable speed high efficiency fans are also available. By
\nproviding zone cooling, ductless split-system air conditioners
\nsave energy, since only the rooms that are occupied need to be
\ncooled. A thermostat independently controls each zone.<\/p>\n
Therefore, operating costs are often lower than those of
\ncentral systems that cool every room, whether it is in use or
\nnot. If you cannot afford to purchase an air conditioner for the
\nwhole house, you can also buy the system one zone at a time. A
\nsingle outdoor unit controls from one to four zones, depending on
\nthe size of the unit. Commercial buildings tend to use larger
\nunits.<\/p>\n
Split-systems are also more secure than window units since
\nthere is only a small hole in the wall. -- The Jakarta Post<\/p>",
