C Oi V Ee R A K O R G w n M S T IN Y A south-facing roof of the winery adjacent to the grape-receiving pad (right) has 24 solar thermal collectors installed. When the sun is shining on the collectors, heat transfer fluid (water) circulates or is pumped through the collector field while absorbing heat. This thermal energy is stored and redistributed from an insulated 1,500-gallon storage tank inside the winery. and execution. To avoid downtime of any vital mechanical components during harvest season, Draper and Baugher allocated a portion of the facility previously used for about 50 wine barrels to house new mechanical equipment. This allowed them to design and build a complete new system while enjoying full functionality of the existing system. The existing heating/cooling piping distribution network was deemed stable and reusable, therefore this extensive system remains in operation. New equipment was interfaced into the existing piping network while maintaining the ability to valve-in and -out new and old components as needed. This allowed for a seamless transition from the old to the new system, even during full harvest activity. The hands-on approach to wine production at Ridge Monte Bello has relied on very little automation. Upgrading the outdated boilers, chillers and pumps, while incorporating solar thermal and chiller heat recovery required the integration of universally adaptable controls utilizing programmable logic (PLC). In designing a system tailored to the needs of this facility, the energy-conservation strategy started with the integration of a new 30-ton chiller with heat-recovery capability. The chilled glycol from the evaporator side of the unit serves to feed fan coils for winery space-cooling, including the wine barrel rooms, offices, etc. This chilled glycol loop is also piped to allow for low-temperature wine tank cooling at most tank stations in the winery. The by-product of the 30-ton chiller is hot water. The condenser side hot water is retained, stored and fed to five boilers in the form of pre-heated make-up water at temperatures as high as 140º F. A 1,500-gallon hot water storage tank serves as this heat-recovery storage. This tank is also heat-supplemented with 24 4-foot by 10-foot glazed flat plate solar thermal collectors that have the capacity to supply water temperatures as high as 180º F. The configuration allows the 1,500-gallon "fossil fuel-free" thermal ballast to be distributed via heat exchangers to provide direct heating to all tank stations while remaining independent of gasfired hot water. This energy-conserving functionality replaced the "gas-only" capabilities of the previous system and will reduce gas consumption consider- The system depicted in the photo is a bioPULSE™ MBR System installed at The RIDGE Montebello in Cupertino, CA BioprocessH2O offers a broad range of treatment solutions for many Industrial applications: • Moving Bed Bioreactor • Membrane Bioreactor • Microfiltration • Ultrafiltration 45 Highpoint Avenue | Portsmouth, RI 02871 www.bioprocessh2o.com 401.683.5400 pr actica l win ery & vin eya r d JANUARY 20 14 15
