The noisiest and bulkiest part of the air conditioner, which contains the compressor, is located outside, while the internal component is much lighter and quieter and can be located in almost any part of the indoor air space. Modern split air conditioners are equipped with remote control and usually have a heat pump option for heating during the winter months. The combination of sophisticated controls and a heat pump means that the indoor air spaces can be effectively "climate-controlled" by modern split air conditioners, keeping the room temperature within 1-2 degrees of the temperature setting. Most split air conditioners now have a number of control modes and timers so that the operation of the unit can be pre-programmed in considerable detail. Even the direction and swing of the discharge fins can usually be adjusted. There is always a coarse air filter on the indoor unit to protect the coils from large particles, and there are often fine filters and air cleaners built in to remove fine dust, tobacco smoke, plant pollen, odors and chemical contaminants.
Monosplit wall mounted air conditioner
A type of fixed air conditioner in which the refrigeration cycle is divided into 2 units. The outdoor unit houses the compressor, the condenser coil and the expansion valve and is designed to transfer heat to the outside by means of a centrifugal fan. The indoor unit contains the evaporator coil and, thanks to a tangential fan, blows cool air into the room. Thanks to a special valve, the refrigeration cycle can be reversed to activate the heat pump mode. The outdoor motor acts as an evaporator to remove cold; the indoor unit condenses and blows hot air into the room.
Ceiling Cassette Air Conditioner
Commonly used in offices with suspended ceilings, the ceiling cassette air conditioner, also known as a cartridge air conditioner, is usually designed to be installed within one or two ceiling tile spaces. The majority of the unit is invisible because it is above the ceiling line, and the only visible part is the decorative bottom panel with its central inlet grille and 4 peripheral outlet louvers. The main advantage of these units is aesthetics, but also that a centrally mounted unit can provide increased cooling or heating capacity over a wide area because the air is distributed in 4 directions.
Floor Mounted Air Conditioner
Floor mounted split air conditioners can really be divided into two types. Firstly, column air conditioners, which are large, high capacity units (up to around 45000 BTU) that are used where a large space needs to be cooled and there may be structural reasons why several smaller outlets cannot be used. Typical applications include lobbies, reception and waiting areas. The high output of these air conditioners means that they produce a strong flow of cool air that does not allow occupants to be close to the air conditioner. Second, there are smaller cabinet style air conditioners that are much smaller, more like the dimensions of a storage heater than the tall upright freezer dimensions of a column air conditioner. Typically their rated capacities are up to about 15000BTU and they are ideal for providing high efficiency air conditioning for new additions and conservatories.
Duct Mounted Air Conditioner
Where a building has a ducted air system, a duct mounted air conditioner is usually the preferred option. Since the ducts are usually hidden in the ceiling cavities, then so is the duct mounted air conditioner. Sometimes referred to as duct or central air conditioners, they also have the advantage of being able to deliver conditioned air to a number of rooms, depending on the layout of the ductwork. Because these air conditioners work within duct systems, they usually have the ability to cool fresh air or a mixture of fresh and recirculated air, depending on the layout and control of the air delivery system. This type of air conditioning is common in applications where there are a number of different rooms or zones, or even separate spaces, that need to be cooled.
