Air conditioning a skyscraper requires a complex system of ducts, vents, and other components. The most common method is to use a central air conditioning system, which consists of an outdoor condenser unit, an indoor evaporator coil, and a series of ducts to distribute the cooled air throughout the building. The condenser unit pumps refrigerant through the evaporator coil, which absorbs heat from the air and cools it. The cooled air is then distributed through the ducts to the various rooms in the building. Additionally, the system may include a thermostat to control the temperature and a humidifier to maintain the desired humidity level. Proper installation and maintenance of the system is essential to ensure the building is properly cooled.
