Room air conditioner

There are a great variety of air conditioning systems that can be used depending on your preference and the location of where the air conditioner is to be used. These air conditioners include room, portable, ductless and central air conditioning systems. The room air conditioner is known as a unitary air conditioner because all the components are in one compact box. These components are the compressor, the condenser, the evaporator and the other systems that have been made small enough to fit in such a system to cool a room. There are components found on the inside and there are the components found on the outside. The evaporative system is found on the inside and consists of the evaporator coil, the blower, the thermostat, filters and the funnel. The condensing unit is found on the outside and is made up of the condenser, the condenser coil and a fan to cool the coil.

The refrigerant changes state from gas vapor to liquid as it collects heat from your environment and ejects that heat to the outside. Refrigerant is special in that it has a very low boiling point meaning that it changes from a liquid to a vapor at low temperatures. The compressor is the central part of a functioning air conditioner. Refrigerant enters the compressor as a low pressure warm vapor and leaves it as a high pressure hot vapor. From the compressor, hot refrigerant vapor moves to the condenser. Here the high pressure hot refrigerant vapor is cooled by air blowing over finned condensing coils by the condenser fan as it moves through the finned coils. As the refrigerant temperature is lowered it changes state from a hot vapor to a hot liquid at high pressure and moves onto the expansion valve. The expansion valve is also an important part of the air conditioner. As the hot liquid refrigerant passes through a tiny opening at high pressure in the valve on one side, it emerges as a cool low pressure mist on the other side because as a gas expands, it cools. So now we have a low pressure cold liquid mist that moves onto the evaporator coil. The low pressure cold liquid leaving the expansion valve now runs through the evaporator coil located in the plenum of your furnace. Here the hot air of your home blows across the evaporator coil and heats it up while the cold coil cools off the air blowing across it and back into your home. As the refrigerant heats up, it boils and changes from a cold liquid and evaporates into a warm vapor. From there it moves back onto the compressor and exterior condensing unit and the cooling cycles continues.

Due to the fact that this room air conditioner installation is half inside and half outside the house during adverse weather conditions you should get it inside or cover it with a wrap that is water proof and thick. The room air conditioner is also referred to as the wall air conditioner and is most commonly found in hotels and other similar establishments because it will be responsible for the air quality of a particular individual.
