Scroll still shapes HVACR industry


Ken Monnier, chief technology offi cer at Emerson Commercial and Residential Solutions talks about the versatility of scroll compressors.

ecognised for its energy efficiency and reliability, scroll compressor technology has helped the HVACR industry generate greater comfort and efficiency for users. Since its broad commercialisation 30 years ago, scroll technology has helped contribute to many of the industry’s efficiency gains. More than 150 million Copeland Scroll compressors have been installed worldwide.


Today, modulation can allow systems to run at varying capacities to meet changing heating and cooling demands in residential, commercial and industrial applications.


Modulation


Scroll technology is more than just an energy efficient solution for specific residential applications. The versatility of the technology can deliver value in new applications outside traditional areas as it can be used to enable more efficient, modulated systems.


Modulating compressor technologies can adjust capacity, either in stages using mechanical means, with tandems, or in a continuous fashion with a variable speed drive for applications that experience varying loads or changing ambient conditions. Modulating technologies also help to reduce compressor cycling, contribute to achieving higher part-load efficiency, and can provide enhanced humidity control at lighter loads, where fixed capacity systems may not operate as optimally as desired.


This new wave of modulating compressors expands the possible applications of scroll technology to lower and higher tonnage ranges within residential and commercial air conditioning applications. For years, the question has always been: “What is the right compression technology based on size or tonnage range of size?” Some equipment manufacturers are now approaching things a little differently. The question they are now asking is: “How can I give system designers one
