An air conditioning system is a technology designed to control the temperature, humidity, and air quality in indoor spaces. It works by removing heat from the air inside a building and transferring it outside, creating a cooler environment. The main components include a compressor, condenser, evaporator, and refrigerant, which work together to circulate cool air. These systems can be found in various settings, such as homes, offices, and vehicles. They help improve comfort during hot weather and can also filter out pollutants, making the air cleaner. Regular maintenance is essential for optimal performance and energy efficiency.
