Air conditioning systems are designed to control the temperature, humidity, and air quality in indoor spaces. They work by removing heat from the air inside a building and transferring it outside, creating a cooler environment. Common types of air conditioning systems include central air conditioning, window units, and portable air conditioners, each suited for different needs and spaces. These systems typically consist of several key components, including a compressor, condenser, evaporator, and refrigerant. The compressor circulates the refrigerant, which absorbs heat from the indoor air and releases it outside. This process helps maintain a comfortable atmosphere, especially during hot weather.
