Air Cooled Chiller
Air-cooled chillers are refrigeration systems that use air to dissipate heat from the coolant or refrigerant. Unlike water-cooled chiller, which rely on a water source and cooling towers, air-cooled chiller use fans to blow air over condenser coils, transferring heat from the refrigerant to the ambient air. They are typically used in smaller to medium-sized applications, such as commercial buildings and industrial processes, where water availability or cost is a concern. These chillers are valued for their relatively simple installation, lower maintenance requirements, and suitability for environments where water conservation is important.
Air Cooled Chiller
Characteristics of
- Cooling Mechanism: Air-cooled chillers use air to remove heat from the refrigerant. The refrigerant absorbs heat from the chilled water in the evaporator, then travels to the condenser where fans blow air over the coils, releasing the absorbed heat into the atmosphere.
- Heat Exchanger: The condenser coils facilitate the heat transfer from the refrigerant to the surrounding air. As the refrigerant releases heat, it changes from a high-pressure vapor to a high-pressure liquid.
- Refrigerant: A fluid, usually a hydrofluorocarbon (HFC), that circulates within the chiller, absorbing heat at the evaporator and releasing it at the condenser. Common refrigerants include R-410A and R-134a.

Energy Efficiency on
- SEER (Seasonal Energy Efficiency Ratio): A measure of cooling efficiency over a typical cooling season, taking into account variations in load and ambient temperature.
- EER (Energy Efficiency Ratio): A measure of the cooling efficiency at a specific operating condition, typically used to compare the efficiency of different chillers under standard conditions.
- Variable Speed Drives: Improve energy efficiency by adjusting the speed of the compressor and fans based on the cooling load, reducing energy consumption during partial load conditions.
Air Cooled Chiller
Components of
- Compressor: The compressor is the heart of the air-cooled chiller. It compresses the refrigerant, significantly raising its pressure and temperature. This high-pressure, high-temperature refrigerant gas is then sent to the condenser.
- Condenser Coils: Heat exchangers where the high-pressure refrigerant releases its heat to the air blown over the coils by the fans.
- Evaporator: Another heat exchanger where the refrigerant absorbs heat from the chilled water or other fluid, thus cooling it down.
- Expansion Valve: Regulates the flow of refrigerant into the evaporator, lowering its pressure and temperature to enhance heat absorption.
- Fans: Blow air over the condenser coils to assist in the heat dissipation process. Can be axial or centrifugal, depending on the design requirements.
- Control System: Manages the operation of the chiller, including starting/stopping the compressor, adjusting fan speeds, and optimizing overall performance for energy efficiency.
- Piping and Valves: Connect the various components and control the flow of refrigerant and chilled fluid through the system.
- Electrical Components: Include wiring, switches, circuit boards, and other elements that power and control the chiller’s operation.
