Room air conditioners

The Room Air Conditioner system is a unit air conditioning system and consists of a compact box with all the components fitted inside it. It is also known as the wall air conditioner or the window air conditioner. It is placed in an open window or through a hole in an exterior wall. Most people prefer the unit installed on a window rather than have to poke holes in the wall. The system ejects heat to the outside in the condensing unit and cools the air on the inside using the evaporator and its coils.

A large house or building has to have many such units for each room. The advantage is that each room can have controlled temperature independently. The disadvantage is the cost of the entire utility bill and the cost of installation and maintenance and any repairs that take place will be quite large.

The room air conditioner has the option of a portable air conditioner. This is also a unitary air conditioner as it has all its parts on an intact compact box. It has the evaporating and the condensing unit. It is usually placed on the floor and can be attached with a hose to the wall. It can be easily moved and the available units have a capacity of 1800-18000W.It is one of the noisiest units available. These units are often found in hotels because they can be operated independently.

Most air conditioners have the following similar parts, the compressor, the condenser, the evaporator, the expansion valve and the drier or accumulator. These parts are interconnected using pipes and valves. Refrigerant is the fluid which is also highly volatile that transports heat from one component to another. The air conditioner basically starts working when you turn on the AC and the refrigerant goes to the compressor where it is compressed and absorbs heat and changes from liquid to gas. Then it goes to the condenser where it is cooled sometimes in some systems the condenser may be fitted with an electric fan. After being cooled and changing back to liquid the refrigerant moves to the evaporator where it is cooled further and then air is blown across it for it to become cool and this cool air is then blown into your environment. The refrigerant then absorbs the heat from the air blown and it reverts to a gas. The drier removes any impurities on the refrigerant using filters and desiccant to absorb any moisture. The expansion valve controls how cool the air you receive will be. Then the process takes place over and over until the room is cooled. This is also referred to as the refrigerative cycle. Before acquiring a unit you should check how energy efficient it is and for some of the appliances industries they offer free installation of your unit.

To select a unit that will serve you without hiking your utility bills select a unit with a high SEER value. You should also schedule maintenance of your unit for it to last long without repairs or replacements.
