Our industry first began to explore modulated scroll compressor technology in the 1980s. While the concept of modulation is not necessarily new, changes in equipment technologies, industry regulations, and consumer preferences over the years have created a need for new ways to modulate cooling systems. The end goal is to design a cooling system capable of continuously adapting its capacity to meet changes in ambient conditions and ultimately deliver greater comfort, energy cost savings, and improved reliability.
There is potential to improve and simplify modulation technology by integrating it with scroll compressors. For this reason, development is underway on several different modulation techniques featuring scroll technology. Each type of scroll modulation is suited to specific a/c or refrigeration applications.
