An HVAC Engineering Professional Explains Types of Compressors Used in Chillers

MEP Consulting Engineers Reviews

The compressor performs a fundamental role in the operation of a chiller, making it possible to remove heat from indoor spaces or from industrial processes via HVAC engineering. Once the refrigerant in a chiller absorbs the heat from a building or process it becomes a gas, but it is incapable of releasing the heat right away in this form. However, after the compressor raises the pressure and temperature of the gasified refrigerant, the heat can be expelled. Air-cooled chillers release heat directly outdoors, while water-cooled chillers release it into a stream of water that is then pumped to a cooling tower.

There are many types of compressors, each with advantages and disadvantages. This article will provide an overview of the three types most commonly used in large commercial chillers. HVAC engineers can determine the best option for your building based on load characteristics.

  • Reciprocating compressor
  • Centrifugal compressor
  • Rotary-screw compressor

In commercial space cooling systems, the compressor is typically the component with the highest electricity consumption. Therefore, it is important to have a well-sized unit, and of a type that is suitable for the application at hand.

Reciprocating Compressors

The reciprocating compressor has a shape similar to that of a car engine cylinder, and it is also known as piston compressor for this reason. Refrigerant that has evaporated after absorbing heat is fed into the cylinder through suction valves, and compressed by the piston before being sent to the condenser.

For a given cooling capacity, reciprocating compressors have a lower upfront cost than centrifugal and rotary-screw compressors in HVAC engineering. They also offer design flexibility, allowing multiple units to be installed together to serve variable cooling loads – individual units are activated or deactivated as needed.

The main limitations of reciprocating compressors are their lower energy efficiency and their demanding maintenance, compared with other types of compressors. Also, although these compressors can achieve good capacity control when multiple units are used, there are few options to modulate the capacity of an individual unit. The two most common options are:

  • ON/OFF Control: Operating the unit intermittently (reduced duty cycle) when its full capacity is not required.
  • Cylinder Unloading: The compressor cylinder can be equipped with additional suction valves or a clearance valve. These valves remain closed when the unit operates at 100% capacity, but may be opened in several combinations to achieve reduced capacity.

Centrifugal Compressors

If a reciprocating compressor can be compared to a car engine, this type is comparable to a water pump because it also uses an impeller, with the difference that it operates with refrigerant. These compressors are also available in hermetic and open models, where the open construction offers higher efficiency.

At rated load, centrifugal compressors are more efficient than both reciprocating and rotary-screw compressors. They also offer a compact construction and are available in a wide range of cooling capacities. Capacity control is normally achieved with inlet vanes that increase or decrease the flow of refrigerant into the impeller.

Despite their superior efficiency at full load, centrifugal compressors suffer from a drastic loss of efficiency at part-load. At very low cooling loads they are rendered unable to operate, due to a phenomenon called surging: refrigerant that is already compressed flows back into the impeller, disrupting its operation.

Centrifugal compressors have the least number of moving parts among the three main compressor types, which means there are less components to service.

However, in most cases the impeller must be factory-ordered if fails; suppliers rarely keep stock because it’s a highly specialized component. Balancing and vibration must also be checked frequently to avoid loss of performance and premature component failure.

Rotary-Screw Compressors

This type of compressor uses two helical screws that are designed to mesh with one another seamlessly while rotating at high speed. They are manufactured with high precision to create a clearance between them, which serves as the compression chamber. These compressors are available in hermetic and open versions like the two previous types described, and capacity control is achieved with a special valve that varies the internal volume ratio.

Although centrifugal compressors are more efficient at full load, rotary-screw compressors offer the best performance during part-load operation. Since the cooling load on a building varies throughout the year, rotary-screw compressors tend to achieve the lowest operating cost overall, even if centrifugal compressors are more efficient at full load.

The main limiting factor of rotary-screw compressors is their high price. If the application does not provide opportunities to take advantage of their capacity control and their superior part-load efficiency, another type of compressor can be considered.

HVAC Engineering: Choosing the right Compressors

High-rise commercial buildings, like those found in many major cities, can generally achieve the best results with a space cooling chiller that uses a rotary-screw compressor. Despite being the most expensive option, it offers the best performance under the variable cooling load that characterizes buildings, while being the simplest system to service – consider that maintenance activities can be quite disruptive in a busy commercial property.

Working with qualified HVAC engineering experts ensures that your property gets a space cooling system that delivers high performance at an optimal energy cost. Chiller selection is a key element, but it is also important to specify adequate complementary systems: air handling units, hydronic piping, cooling towers, HVAC controls, etc.
