If the control optimization system for chiller plants were installed throughout GSA’s portfolio, energy savings of 20% to 50% would result, yielding annual cost savings between $5 million and $13 million. The minimum water volume is based upon the chiller manufacturer's requirements, 3 to 6 gallons per ton for typical air conditioning and when the temperature accuracy is critical 6 to 10 gallons per ton. Chilled water plants are being built at a brisk pace so there is a great opportunity to apply the principals of this guide. Along with Independent Square, JEA has targeted the Landing as a possible customer. Seawater Air Conditioning: A Basic Understanding Introduction Seawater Air Conditioning (SWAC) is an alternate-energy system that uses the cold water from the deep ocean (and in some cases a deep lake) to cool buildings. A water-chiller refrigeration ton is defined as: 1 Refrigeration Ton (RT) = 1 TONS cond = 12000 Btu/h = 200 Btu/min = 3025. Enter the Cost of Water and Sewer Charges per thousand gallons. Replacement cost around $25 million. Today's most efficient centrifugal chillers can operate in the 0. An example of the dollar savings expected for refurbishing a tower vs. A 10° change is proportional to about 2. Air-cooled chillers are less efficient than water-cooled chillers but cost less as well. temperatures and condenser water flow rate. Today, a high-efficiency centrifugal chiller carries a rating of about 0. Finally, a suitable chilled water supply tariff will be determined that generate a win-win. • Chilled water decoupling valve control via 0‐10V output and chiller ∆P set point. Operating Temperature Unit is designed for operation in standard evaporator temperature (greater than 40 F, 4 C) modes.
