The document summarizes a case study of an energy saving compressor retrofit conversion project completed by BITZER US, Inc. for the Holiday Inn in Ocean City, Maryland, owned by the Harrison Property Group. The aging York reciprocating compressor was replaced with a BITZER screw compressor, which achieved the objectives of using an alternative to R22, improving system performance, and reducing energy costs by 50% or $600 per month. Additional benefits included step capacity modulation and reduced sound levels from the mechanical room. Impressed with the results, the Harrison Group has since completed five more BITZER conversions.
