HVAC systems in high-rise buildings are designed to provide efficient and effective climate control for the occupants. The system typically consists of a central air handling unit, which is connected to a network of ducts and vents that distribute conditioned air throughout the building. The air handling unit is responsible for heating, cooling, and filtering the air, and is usually connected to an outdoor unit that provides fresh air to the building. The system is also connected to a thermostat, which allows the occupants to adjust the temperature to their desired level. The system is designed to maintain a comfortable temperature throughout the building, while also providing adequate ventilation to prevent the buildup of pollutants.
