Split air conditioner

There are many kinds of air conditioners in the industry; these include the wall air conditioner, the central air conditioner, the split system air conditioner and the portable air conditioner among many other air conditioners. These are mostly made up of the compressor, the condenser, the evaporator, the expansion valve and the drier or the accumulator. The refrigerant is the liquid used to ferry heat from one component to the other. When it absorbs heat it changes state from liquid to gas and when cooled it changes back to liquid. The compressor pumps the refrigerant across all the other components. In the compressor the refrigerant is compressed until it becomes a hot vapor. The hot gas refrigerant moves from the compressor to the condenser. In the condenser the refrigerant is cooled by a condenser fan and it changes state from gas to liquid. The liquid then moves to the expansion valve where its heat is regulated. Then it moves to the evaporator where it is cooled even further and air is cooled by being blown across the cool refrigerant and it absorbs the heat from the air and changes into a gas.

Always get a unit that is the perfect size, a small air conditioning unit will not effectively cool the house and a unit that is too large will run your bills too high as it turns on and off unnecessarily. It is always recommended to get a contractor to get you the best deal and for him to check your house for the most suitable type of unit. The contractor will check window dimensions, any previous duct work, the floor surfaces and the overall size of the house. Based on this information he will then select the most suitable fit with a high SEER rating for your house.

The split-system air conditioners have two types of systems, mini-split and central systems. Both systems have the evaporator and condenser in different places. The mini-split system can cool a number of rooms in the same building. It is quite advantageous because of its small size and its ability to cool more than one room.

A portable split system has an indoor unit on wheels connected to an outdoor unit via flexible pipes, similar to a permanently fixed installed unit. The split system or ductless system is technically called a "packaged terminal air conditioner" or PTAC. You see these occasionally in home applications but more commonly in hotels, motels and apartments. The split system breaks the air conditioning system into two packages or terminal units and refrigerant tubing passes through the wall connecting both package units.

One terminal package is the condensing unit located on the exterior and includes the compressor, condenser and condenser fan. The other terminal package is the evaporative unit located on the interior and handles air cooling and distribution. The internal evaporative unit includes the fan, expansion valve and evaporator coil.

The condensing unit is placed on the outside and it consists of the condenser, its fan and the compressor. While on the inside the evaporative unit has the evaporator, its fan, the expansion valve and the evaporative coil. The inside unit keeps the room cool even as it expels heat to the outside through the condensing unit. Once the air is cooled on the inside the heat carried through the refrigerant is expelled to the outside and this way the cycle continues until the room is cool enough to be comfortable and can then it can be kept at those conditions.
