As part of our ongoing efforts to replace older, less efficient equipment on campus with more efficient models, University Facilities upgraded the cooling equipment in the walk-in refrigerators and freezer at the Freeman Dining Hall in early February 2021.<\/p>\n
Four condenser units were replaced – three in the walk-in refrigerators and one in the walk-in freezer. Two of the units were over 20 years old, but all of the units were what’s known as “once through water-cooled condensers” meaning that water was piped into the condenser and passed through the system a single time before going down the drain. As you can imagine, this used a considerable amount of water!<\/p>\n
The new condensers are air-chilled units which are more efficient and will save a significant amount of water. In fact, the water savings alone will pay for the project cost in less than one year<\/em>. The total annual cost of water for the four old condenser units was approximately $75,500 and the replacement was completed for a total project cost of $65,000.<\/p>\n University Facilities is excited to be able to perform these types of equipment upgrades and looks forward to completing more in the future.<\/p>\n We’ll need to do some math to figure it out.<\/p>\n One condenser unit in the walk-in freezer used 480 gallons of water per hour with an average operation time of 16 hours per day for 365 days per year.*<\/p>\n 480 x 16 x 365 = 2,803,200<\/em> gallons per year<\/strong><\/p>\n One condenser unit in a walk-in refrigerator used 288 gallons of water per hour with an average operation time of 18 hours per day for 365 days per year.*<\/p>\n 288 x 18 x 365 = 1,892,160<\/em> gallons per year<\/strong><\/p>\n The Freeman Dining Hall has one freezer and three refrigerators, so<\/p>\n 2,803,200 + (1,892,160 x 3) = 8,479,680<\/em> gallons of water per year.<\/span><\/strong><\/p>\n To give you a better idea of how much water that is, it’s over 504,000 showers or almost 424,000 loads of laundry!**<\/p>\n *figures were obtained from the equipment’s manufacturer.<\/p>\n **at 2.1 gallons per minute per the average 8 minute shower (source<\/a>) and 20 gallons per load (source<\/a>).<\/p>\n","protected":false},"excerpt":{"rendered":" As part of our ongoing efforts to replace older, less efficient equipment on campus with more efficient models, University Facilities upgraded the cooling equipment in the walk-in refrigerators and freezer at the Freeman Dining Hall in early February 2021.
