The work of this project in Springfield, Massachusetts includes, but is not necessarily limited to, replacement of the MassMutual Center Ice Plant, which is approximately 22 years old and is approaching the end of its useful life. The existing system utilizes R-22 refrigerant, which has since been banned from domestic production or foreign import due to the Clean Air Act and has experienced unpredictable price fluctuations along with its very high global warming and ozone depletion impact. A new refrigerant, CO2, has been selected for use to be used by the new packaged chiller skid equipment as part of this new work. Two (2) chiller skid packages with integral equipment, 40% Ethylene glycol pumps, two (2) rooftop mounted evaporative condensers, condenser pumps, condenser holding tank, condenser water treatment, expansion tanks, 40% Ethylene glycol feeder skid, refrigerant monitoring system and associated equipment/accessories serving the ice plant will be demolished, removed, replaced as part of this new work. The existing electrical switchgear in the Mechanical Room will be demolished and upgraded. In addition, a new 100% water,140°F Zamboni/Ice melt system will be installed. All as more fully set forth in the Drawings and Notes.
