Understanding how an AHU (Air Handling Unit) and a chiller work is crucial for optimizing HVAC systems in commercial and industrial settings. Both play integral roles in maintaining indoor air quality and temperature control.

How an AHU Works

1. Function of AHU

  • Air Handling Unit (AHU): An AHU is a crucial component in an HVAC system designed to condition and circulate air. It processes air by filtering, heating, cooling, and humidifying it before distributing it throughout the building. Learn more about the function of AHU.

2. Components of AHU

  • Filter: Removes dust and impurities from the air.
  • Coils: Heat or cool the air. Coils may be connected to a chiller or a heating system. Discover more about AHU components.
  • Fan: Circulates air through the system.
  • Ductwork: Distributes conditioned air to various parts of the building.

3. Operation of AHU

The AHU pulls in outside air through an intake, processes it with filters and coils, and then distributes the conditioned air through ductwork. Explore more about AHU operation.

How a Chiller Works

1. Function of a Chiller

  • Chiller: A chiller removes heat from a liquid, typically water, which is then circulated through a system to cool air or other equipment. Chillers are commonly used in large-scale cooling applications such as industrial processes and commercial buildings. Learn more about the function of a chiller.

2. Components of a Chiller

  • Evaporator: Absorbs heat from the liquid being cooled.
  • Condenser: Releases the absorbed heat into the environment.
  • Compressor: Compresses refrigerant to transfer heat.
  • Expansion Valve: Regulates the flow of refrigerant. Discover more about chiller components.

3. Operation of a Chiller

A chiller works by circulating refrigerant through the evaporator to absorb heat from the liquid, then compressing the refrigerant and releasing the heat into the environment through the condenser. The cooled liquid is then sent to the AHU or other systems. Explore more about chiller operation.

Integration of AHU and Chiller

1. Working Together

  • AHU and Chiller Integration: In an HVAC system, the AHU and chiller work together to ensure effective climate control. The chiller cools the water, which is then used by the AHU to condition the air. Learn more about AHU and chiller integration.

2. System Efficiency

  • System Efficiency: Proper integration and maintenance of AHU and chiller systems are essential for optimizing energy efficiency and performance. Discover more about system efficiency.
