Air conditioning equipment is a system of machines and components that are used to regulate the temperature, humidity, and air quality of a space. It typically consists of an outdoor unit, an indoor unit, and a network of ducts and vents to circulate the air. The outdoor unit contains a compressor, condenser, and fan, while the indoor unit contains an evaporator and fan. The system works by cooling the air inside the space and then circulating it throughout the area.
