Understanding the Basics of Air Conditioning Systems

Air conditioning is the process of treating indoor air to control certain conditions necessary for human comfort. It works by introducing warm air into a system and dispersing cold air, making use of the principle of phase change. A window air conditioner is a unit air conditioning system that is placed in a window or through a hole in an exterior wall. It continuously draws air from the space to be cooled and is cooled by cooling the unit coil and returned to the same space for cooling.

In the early years, air conditioning helped drive the manufacturing of everything from baked goods to war supplies. Today's “modern cooling systems” continue to operate according to the same basic principles, providing cold air to people inside. It consists of a complete vapor compression system having compressor, condenser, evaporator, expansion device with motor, blower, fan, air filter, grilles, fresh air damper and control panels. Despite the fact that the outside temperature varies, the indoor temperature remains constant.

Heat can be removed or added to the conditioned space depending on the environmental conditions. If a system is too large, it will not work well and will not properly dehumidify indoor air. These portable units draw indoor air out through a single duct, negatively affecting your overall cooling efficiency.
