A room air conditioner is a small enclosed cooling gadget that mounts through a window or through a wall for venting and for air exchange.

The main aim of air conditioning equipment is to cool the room air within a small, confined area. They cannot be used as a “whole house” air conditioning system. They can be often used in houses or apartments which people stay on rent. It makes it unable to install permanently. there. A room air conditioner comes with a control panel mounted somewhere on the front or on top. It gives the user an easy access to the controls. Usually there are independent controls for setting the target room temperature and for controlling the fan speed thus circulating the conditioned air in the room.

Most people are unaware that room air conditioning units do not cool a room technically. It is apt if said that room air conditioners remove the heat from the air and then moves it elsewhere to where the unit has been vented.

A pressurized refrigerant, R-22, flows through the air conditioner unit when it is put on. When the unit is on, the condenser will pull the refrigerant gas into the air conditioning system getting it pressurized and raising the temperature of the gas. This heated, high-pressure gas is then made to move next to the condenser coils, located on the outdoor portion of the unit. The fans then distribute the heat that has been collected.

The cooled gas then gets transformed into a liquid. It is then made to move to the interior part of the room air conditioner to the evaporator coils. At this point, these coils are able to can absorb the heat that is in the room. The fan then helps in moving the air throughout the unit. The thermostat controls the cycling of this process to maintain the needed temperature in the room.

Some room air conditioners do have mechanical controls, like knobs and push buttons. The newer air conditioning units has electronic touch pads that control the functionality and regulate the mode the units operate in, the temperature set point, a timer for automatic shut off and powering on, and various other conveniences. Most among these are designed to make the unit as energy efficient as possible.
