Review chiller components: discuss critical chiller components and present the purpose and design within the system; present a basic understanding of refrigerant and the thermodynamics present in their system; showcase common chiller failures and techniques for self-diagnosis and repair; and chiller performance related to outside temperatures. Review glycol selection and maintenance: discuss common glycol types, glycol attributes, and proper selection for a brewery; define proper dilution rates and process temperatures; and discuss proper glycol maintenance. Critical design parameters for breweries: explore chiller plumbing design and options; calculations to determine proper chiller sizing (bigger is never better); importance of staging ability and cooling redundancy; and incorporating expansion requirements in the predesign stage. Opportunities for energy savings: staging ability and its inherent benefit to energy savings; use of freq drives, EC fans, and oversized condensers; and calculate potential savings and prove long-term benefits.
