# Air Conditioning
## Description:
Air conditioning (AC) systems are mechanical systems designed to regulate indoor temperature, humidity, and air quality by cooling and sometimes heating the air. They typically consist of an indoor unit (evaporator), an outdoor unit (condenser), and a refrigerant system that transfers heat. AC systems can be split-type, ducted, window-mounted, or portable.
## Purpose:
The primary function of air conditioning is to provide thermal comfort by cooling and dehumidifying indoor spaces, especially in warm climates. Additionally, modern AC systems improve indoor air quality by filtering dust, allergens, and pollutants. They are widely used in residential, commercial, and industrial buildings to maintain comfortable and controlled environments.
