Before servicing any system, check the compressor and system labeling to determine whether the system being serviced contains a flammable refrigerant.A compressor designed for flammable refrigerant use should have the refrigerant designation printed on the compressor serial label, and may also display a separate flammable refrigerant label (see below): Compressor with: (1) serial label, (2) …
DeCO2ded: Understanding ROI on CO2 Refrigeration Systems Here’s the question many grocers ask when they’re considering retrofitting or replacing commercial refrigeration systems: How much will it cost to switch from a traditional hydrofluorocarbon-based system to 100% CO2? But the answer — an immediate dollars-and-cents calculation — is neither sufficient nor strategic. A better question: …
Modern compressors today commonly have the motor within the compressor shell. Refrigerant gas circulates around the motor to help keep it cool. Cool-running motors give better performance and longer operating life. These are the three factors that influence motor cooling. Excerpt from Technical Institute Manual 1, from the ONLINE STORE at the Refrigeration Service Engineers …
