Mobile air conditioning
Since the invention of the first air conditioner many modifications have been made and these have led to the creation of the different types of air conditioners. The major air conditioners in the market are the central air conditioner, the window air conditioner, the portable air conditioner and the split or ductless systems. The portable air conditioner is also known as the mobile air conditioning unit. This is because you can carry it from home to the office and back as you wish. It is also referred to as a unit air conditioner in that it has all the components of a major air conditioner made in a size to fit a compact box. These components include the compressor, the condenser, the evaporator, the expansion valve and the drier or accumulator. They function in the same way they would in a bigger air conditioner. The compressor will pressurize the refrigerant and it will absorb heat and change state from liquid to gas. Then the refrigerant gas will move to the condenser where it will be cooled by electric fans to revert back to liquid. Then it will move across all the other components to ensure that your room is well cooled. It is placed on the floor and connected to a hose attached to the wall that expels heat to the exterior. The disadvantage of this unit is it is the noisiest.
Mobile air conditioning is found with capacities of between 1800 to 18000 W output and can either be evaporative or refrigerative systems. There is also another type of portable air conditioner known as a portable split system that is connected to the exterior unit via pipes and tubes. It is also known as a terminal unit or PTAC, packaged terminal air conditioner. This AC system has two distinct units that serve to cool the rooms with interconnecting tubing for the refrigerant to easily move through both systems. The two units are the condensing and the evaporative unit. The condensing unit is placed on the outside and t 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. For systems that are connected to the outside during harsh weather such as winter with the snow and water you will need a strong protective covering for the outside unit. Alternatively you can move it to the inside of the house until the season passes as you will not need to cool your home in winter.
You can maintain these systems for years with regular maintenance to prevent frequent break downs and repair.
