Leading Air Cooled Chiller Manufacturers

Air cooled chillers are a cooling system that uses a shell and tube evaporator to exchange heat. A refrigerant system removes heat from the water and transfers the heat to the air around the chiller. Air cooled chillers are very compact, easy to install, and exceptionally efficient. Read More…

Air Cooled Chillers Air cooled chillers use air to absorb heat from a process liquid and transfer it into the atmosphere. Air cooled chillers are one of three major types of liquid chillers, providing a straightforward chilling option used in many industrial applications. The other two types of chiller are water-cooled chillers and evaporation-cooled chillers.

How Air Cooled Chillers Work

The size and design of air cooled chillers make them very popular for commercial and office buildings. Since they do not require a cooling tower, they can be portable and located on the top of a building or the ground near a building. Air cooled chillers remove heat from the water and harmlessly eject the hot air into the atmosphere and environment.

Components of an air cooled chiller:

  1. Compressor

    Compressors for air cooled chillers can be screw, scroll, or reciprocating.

    • Scroll Compressors

      A scroll compressor has a scroll that orbits inside the housing. As the scroll orbits, it forces gas to the center of the scroll, where the gas reaches discharge pressure and is released.

    • Screw Compressor

      Screw compressors are found in large cooling units with sizes of 20 to 300 tons and can be externally or internally driven. The helical rotors of a screw compressor trap and compress gasses.

    • Reciprocating Compressor

      A reciprocating compressor is like an engine with a cylinder, piston, and a rod to achieve compression. An electric motor supplies the power for the unit. The piston is moved inside the cylinder by the rotation of a crank attached to the rod. When the piston moves backward, it pulls in the gas. As the piston moves forward, it compresses the gas before it is released.

  2. Condenser

    The four parts of a condenser are the housing, coils, compressor, and fan. Although there are a wide variety of designs for condensers, they all work following the same basic principle. The main part of the condenser is the coils, which are made of copper or aluminum and contain the refrigerant.

  3. Fans

    Fans pull air across the condenser's coils and force it out of the unit into the atmosphere.

  4. Expansion Valve

    The expansion valves control the flow of refrigerant and help change liquid refrigerant to gas for the evaporator. The evaporator core would freeze if there is too much refrigerant flow or be inefficient if the flow is too low.

  5. Evaporator

    In the evaporator, chilled water is produced, and the heat from warm water is removed and sent to the condenser.

Cooling Process of an Air Cooled Chiller

Step One

The compressor provides the force that drives the refrigerant, which leaves the compressor headed to the condenser at high pressure and temperature and as a superheated vapor.

Step Two

In the condenser, the refrigerant makes its way through coiled horizontal pipes transferring thermal energy into the air stream. The heated air is moved along by fans placed on the unit.

Step Three

The expansion valve holds the refrigerant to maintain its high pressure. The small orifice of the valve permits small amounts of refrigerant to continue to flow. However, as it enters the other side of the valve, the refrigerant experiences a pressure drop, turns into a vapor, and reaches a very low temperature.

Step Four

When the low-temperature refrigerant leaves the expansion valve and enters the evaporator, it passes through another set of horizontal tubes where it is surrounded by chilled water. The water and the refrigerant flow in opposite directions. During this process, the refrigerant picks up the unwanted heat from the water, which leaves with its thermal energy gone and at a very low temperature.

Air Cooled Chiller System

Types of Air Cooled Chillers

Air cooled chillers are used where the discharge of heat from the chiller is not a concern. In areas with cold temperatures, the discharged heat is used to heat buildings, manufacturing plants, and industrial operations. The primary types of air cooled chillers are stationary and portable. The compact design of air cooled chillers makes it possible to place them in various locations. Although they are compact and can be portable, they still provide a highly efficient cooling system.

Stationary Air Cooled Chillers

A stationary air cooled chiller is the central part of a cooling system and is normally never moved. Therefore, it has all the characteristics of an air cooled chiller with the same type of efficiency and stability. Stationary air cooled chillers are referred to as central cooling chillers and are used where the release of heat from the chiller is not an issue.

Portable Air Cooled Chillers

Portable air cooled chillers offer the convenience of being able to be moved to meet the needs of a location. They are used for various applications, from temporary cooling of a location to permanent cooling of factory operations.

Benefits of Air Cooled Chillers

The many benefits of air cooled chillers make them an ideal solution for various cooling applications.

  • Air cooled chiller condenser coils always have plenty of fresh air. When the refrigerant reaches the condenser coils, the fresh air absorbs the heat.
  • The proportional integral derivative (PID) temperature controller prevents harm from high temperatures and has a set scale that can be used to shut off the unit.
  • Cooling fans connected with the condenser provide a constant fresh air supply.
  • Heat is exchanged by the liquid refrigerant in a corrosion-resistant shell and tube heat exchanger.
  • A key benefit of air cooled chillers is that they are environmentally friendly since they do not release toxic fumes or chemicals.
