can pass through a hole in the wall barely 10 cm in diameter). The outdoor unit houses
the compressor, condenser, and the condenser fan. The indoor unit consists of the
evaporator (cooling coil) and the evaporator blower.
Cooling capacity: 0.5–5 TR (tonnes of refrigeration).
Features: Split air-conditioners have higher initial cost as compared to window units.
However, split air-conditioners have higher efficiencies and low noise-levels as the noisy
components like condenser, compressor, and so on, are installed within.
Bureau of Energy Eficiency labelled air conditioners
The Bureau of Energy Eficiency (BEE) has a Standards and Labelling Programme targeting household and other equipments like frost-
free (no-frost) refrigerator, tubular luorescent lamps, room air-conditioners, direct cool refrigerators, distribution transformers, induction
motors, pump sets, ceiling fans, LPG, electric geysers, and colour TVs. The appliances are rated on a scale of one to ive stars based
on their performance and energy consumption. Five star rating indicates highest eficiency rating and, thus, highest energy savings.
The labels provide information about the energy consumption of appliances, and, thus, enable consumers in making informed choices
while buying.
In the category of air-conditioners, this programme covers split air-conditioners and window air-conditioners. With effect from January
2010, sale of room air-conditioners is not permissible without BEE label and at least one star is mandatory for selling the product. The
eficiency of an air-conditioner (AC) is determined by its energy eficiency ratio or EER (ratio of coiling output to total electric energy
input). The number of stars on the BEE label indicates the eficiency of an AC; the higher the number of stars, the more eficient the AC.
Information related to BEE labelled AC models of different brands available in the Indian market is available on the BEE website (http://
www.bee-india.nic.in/). The following table shows the format in which the information is available on the website.

Central AC system
Central AC systems are further divided into ductable packaged air-conditioners and central
plants. The term ‘ductable’ implies any AC system that is suitable for ducting.
i. Ductable packaged AC systems can be divided into the following two categories.
• Air-cooled ductable splits: The indoor units in these systems are located above the false
ceiling and connected to the ducting. The location for installing indoor units should
be selected with great care. Ideally, the indoor units should be located in areas that are
easily accessible, like corridors. Installation of the indoor units in conditioned areas or
above false ceiling should be avoided.
