Listen For Any Strange Noises While The Unit Runs
If you hear any squealing or knocking the unit’s motor and belts may need lubricating or replacing. It’s best to call a certified technician to do these jobs. Air conditioning (often referred to as AC, A.C., or A/C) is the process of removing heat from a confined space, thus cooling the air, and removing humidity.
This process is used to achieve a more comfortable interior environments, typically for humans or animals; however, air conditioners are also used to cool rooms filled with heat-producing electronic devices, such as computer servers or power amplifiers.
Air conditioners often use a fan to distribute the conditioned air to an occupied space such as a building or a car to improve thermal comfort and indoor air quality.
Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult to massive units installed on the roof of office towers that can cool an entire building.
The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants. (chemicals which remove moisture from the air).
Designed to improve manufacturing process control in a printing plant, Carrier’s invention controlled not only temperature but also humidity. Carrier used his knowledge of the heating of objects with steam and reversed the process.
Instead of sending air through hot coils, he sent it through cold coils (filled with cold water). The air was cooled, and thereby the amount of moisture in the air could be controlled, which in turn made the humidity in the room controllable.
