Rising cooling needs for the residential and commercial air conditioning sectors and the
demand for higher SEER require HVAC&R to handle cooling loads below the design
condition. Though several studies exist focusing on a particular capacity modulation
strategy, there is no extensive study that explores all these available modulation strategies
in the same experimental facility. This paper is the next step to a previous paper that
compared two capacity controls for scroll compressors (single speed and two-stage …
