How Do Package Units Work?

Here's a basic overview of how rooftop/package units work:

• Air Handling Unit (AHU): This is the main component responsible for moving air. It contains a fan that draws in air from the building through return ducts. This air can be either heated or cooled depending on the system's mode.
• Heating Element (if applicable): If the system is equipped for heating, it will have a heating element. This could be a gas burner, electric coils, or some other type of heating mechanism.
• Cooling Element (if applicable): Similarly, if the system is designed for cooling, it will have a cooling element, typically a refrigeration system that uses a compressor, condenser, evaporator, and refrigerant to absorb and release heat.
• Air Filter: Before the air is conditioned, it passes through a filter to remove dust, dirt, and other particles. This helps maintain indoor air quality.
• Thermostat: This is the control interface that allows users to set the desired temperature. The thermostat monitors the indoor temperature and signals the unit to adjust its operation to achieve the desired setting.
• Ductwork: The conditioned air is distributed throughout the building via a network of ducts. Supply ducts carry conditioned air to different rooms, while return ducts bring air back to the AHU for reconditioning.
• Ventilation: In addition to heating and cooling, package units often include a ventilation system to bring in fresh outdoor air and maintain indoor air quality.
• Control System: This includes sensors and controls that monitor various aspects of the system, such as temperature, humidity, and airflow. These controls work in conjunction with the thermostat to regulate the system's operation.
• Exhaust (optional): Some package units may have an exhaust system to expel stale air from the building.
• Condensate Drain: In cooling mode, moisture is condensed from the air and needs to be drained away to prevent damage to the unit and the building.
