A room Air conditioner is a small enclosed cooling mechanism that is able to be placed in a window or through a wall for venting and for air change . Lately , there has also been an introduction of portable air conditioning units, which are housed in cases that is on the floor near a window with a tube for venting. These portable units usually have casters mounted to the bottom of the case making it possible for them to easily move from one room to another as needed.

The purpose of air conditioning equipment for a room is to cool the air inside a small, confined space and they are not produced as a “whole house” air conditioning system. They are most often used in houses where people are renters; therefore , they are not permanently installed and can be removed and taken to a new location if the occupant moves .

Usually , a room air conditioner will have a control panel mounted anywhere on the front or on top, in order to give the user very easy access to the controls. In general , there are independent controls for regulating the target room temperature and for controlling the fan speed for circulating the conditioned air around the room .

Most people don’t know that room air conditioning units do not “technically” cool a room. It is more correct to say that room air conditioners eliminate the heat from the air and then motions it elsewhere to where the unit has been vented.

A pressurized refrigerant, R-22, runs through the air conditioner unit when it is switched on. While the unit is on, the condenser will pull the refrigerant gas into the air conditioning system and then pressurize it, which raises the temperature of the gas . This heated, high-pressure gas travels next to the condenser coils, which are situated on the outdoor portion of the unit where the fans distribute the heat that has collected .

The cooled gas then grows condensed into a liquid, which goes to the interior part of the room air conditioner to the evaporator coils. The fan then moves the air throughout the unit. The thermostat controls the cycling of this process to support the desired temperature in the room.

Several room air conditioners have mechanical controls, such as knobs and push buttons. The newer air conditioning units are controlled with Elektronik touch-pads that tend to provide more functionality and can control the mode the units operate in, the temperature set point, a timer for automatic shut off and powering on, and various other conveniences, most of which are created to make the unit as energy efficient as possible.
