While looking for new ways to cut cooling costs, often overlooked elements for energy-efficient operation of air conditioning systems is the compressor.
Selecting Energy-Efficient Technologies For Your Commercial HVAC System
- Screw technology Screw compressors are available in oil-injected and oil-free versions. While oil-injected screw compressors require a smaller initial investment and are easy to install, they’re less energy efficient than oil-free models.
- Centrifugal technology Designed for easy application and reliable operation, centrifugal compressors deliver superior efficiency, particularly in commercial air conditioning applications that require constant high volumes of conditioned air. Besides outstanding energy efficiency, these compressors have a long life span, facilitate compliance with national energy codes, and can help reduce the carbon footprint. A centrifugal compressor with multiple stages of compression can help generate additional savings, whether it operates at part or full load.
- Reciprocating technology Although a conventional reciprocating compressor isn’t as efficient as other types of compressors, water-cooled models are some of the most energy-efficient products available nowadays. The fact that they can be used in different part- and full-load applications makes them versatile enough for a wide variety of commercial and industrial cooling and refrigeration applications.
- Inverter scroll technology Available with built-in variable speed drives, which provide excellent part-load efficiency, inverter scroll compressors are able to reduce energy consumption and deliver superior efficiency and comfort levels by continuously adjusting their operation according to ambient conditions.
- Economizers When the outdoor conditions are more favorable, the economizer shuts off the compressor and allows cooler air to enter the system. In addition to increasing the cooling capacity by 20%, thus reducing the need for electrical cooling along with the costs associated, an economizer extends the life of the compressor. The integrated differential enthalpy economizer is more efficient than other types because it communicates directly with the thermostat for real-time adjustments.
