An Air Conditioner (often referred to as AC) is a system designed to dehumidify and extract heat from an area. The cooling is done using a simple refrigeration cycle. The definition of cold is the absence of heat and all air conditioning systems work on this basic principle. Heat can be removed through the process of radiation, convection, and heat cooling through a process called the refrigeration cycle. Refrigeration air conditioning equipment usually reduces the humidity of the air processed by the system. The relatively cold (below the dew point) evaporator coil condenses water vapour from the processed air, sending the water to a drain and removing water vapour from the cooled space and lowering the relative humidity. An evaporative cooler is a device that draws outside air through a wet pad, such as a large sponge soaked with water. The sensible heat of the incoming air, as measured by a dry bulb thermometer, is reduced. The total heat (sensible heat plus latent heat) of the entering air is unchanged. HVAC is an acronym that stands for the closely related functions of «Heating, Ventilating, and Air Conditioning
