When I started my HVAC career in 1997, our DX compressor options in packaged rooftop units were limited.
On/off compressors, two-stage, and hot gas bypass, if my memory serves.
None of these worked well to control temperature and humidity over all load conditions, especially for high-content OA applications.
Today, we are lucky to have digital compressors and variable-speed compressors.
The common question is, which compressor should I use and why?
Well, this informative guide by AAON answers those questions and more.
This compressor technologies guide gives an overview of the benefits and costs of different compressor configurations and the efficiencies possible with varying configurations of rooftop units. AAON recognizes many reasons for choosing a specific compressor technology and offers many options to meet the needs of a particular application.
This PDF guide has helped me understand the different options, and I hope you find it useful, too!
