Types of Air Conditioners



The basic types of are room , central split-system, central and packaged.

Room air conditioner
Room air conditioners are installed directly in the windows or walls, which means they have no pipeline. The fan spray faces inside, while the condenser fan is facing outside.

Room Air Conditioners

Room fresh air conditioners rooms than the entire house. If they provide cooling only where they are needed, room air conditioners are cheaper to use than central units, although their effectiveness is generally lower than that of central air conditioners.

Smaller room air conditioners (ie., those less than 7.5 amps of ) can be connected to any 15 or 20 amp, 115 volt circuit of household that is shared with any other device. Larger air conditioners room (ie., Those drawing more than 7.5 amps) need their own circuit of 115 Volts. The largest models require a dedicated circuit of 230 volts.

Central Air Conditioners

The central air conditioners circulate fresh air through a system of ducts supply and return. The supply ducts and registers (openings in walls, floors or covered by grills) carry the air-cooled air conditioner at home. This cooled air becomes warmer as it circulates through the house, so it goes back to the central air conditioner ducts and registers return. The air conditioner is either a central is a unit of split-system or a unit packed.

In a split-system central air conditioner, an outdoor metal cabinet contains the condenser and compressor, and an indoor cabinet contains the evaporator. In many split-system air conditioners, this indoor cabinet also contains a furnace or the indoor part of a heat pump. The air conditioner’s evaporator coil is installed in the cabinet or main supply duct of this furnace or heat pump. If your home already has a furnace but no air conditioner, a split-system is the most economical central air conditioner to install.

In a packaged central air conditioner, the evaporator, condenser, and compressor are all located in one cabinet, which usually is placed on a roof or on a concrete slab next to the house’s foundation. This type of air conditioner also is used in small commercial buildings. Air supply and return ducts come from indoors through the home’s exterior wall or roof to connect with the packaged air conditioner, which is usually located outdoors. This combination of air conditioning and central heating system eliminates the need for a separate inside furnace.

A packaged air conditioner sits outside the house next to the foundation or on the roof. Its cabinet contains the evaporator, condenser, compressor, and all other parts of the air conditioner. Supply and return ducts connect to this outdoor cabinet.
A packaged air conditioner sits outside the house next to the foundation or on the roof. Its box contains the spray, condenser, compressor and all other parts of the air conditioner. The supply pipes connect to the back of the box outside.
