Wall air conditioner

The wall 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 moisture from the evaporator coil drains along the bottom of a metal pan and drips to the exterior through a hole or condensate drain tube. The whole package is neatly housed in a metal enclosure and sits partly in and partly out of your room's window. It ejects heat out one end and blows cooled air out the other end.  This system is usually covered during adverse weather conditions to prevent damage to its parts. This type of air conditioner is mostly found in apartments and hotels where there is a huge building but each individual can monitor how they would like their room temperature to be.

This type of air conditioner can also come as a portable air conditioner. This system is another type of the unitary air conditioning system. The portable air conditioner consists of a unit that has also had its components made smaller to fit within it and it is mobile and can be moved around and it usually discharges exhaust heat using a hose vent through an exterior wall. Portable air conditioning units are the noisiest type of air conditioners and can typically cool rooms under 500 SF. It also has traits similar to the window air conditioner where heat is removed at one end and cool air comes from another end. The only difference being the portable air conditioner is usually placed on the floor.

Then the other type is the split or ductless air conditioner. The split system or ductless system is technically called a "packaged terminal air conditioner" or PTAC. They are found in home applications but more commonly in hotels. The split system air conditioning system has 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 outside and includes the compressor, condenser and condenser fan used to cool the condenser. 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 to cool the evaporator coil, expansion valve and evaporator coil. Then there is the central air conditioning. The central air conditioning system is the premium cooling solution for your home. It is the quietest, best performing and most comfortable. The only real risk is that the system be sized appropriately for your home. If it is sized too large it will not perform well and it might short cycle.
