Magnitude ® Magnetic Bearing Water-cooled. case, you should review the section on Optimizing Existing Chilled Water Systems to evaluate ways to make your existing chiller system more efficient. kahsh corrosion due to water flow rate in the pipes should be made to the extent that unjustified increase in the cost of plumbing pipe diameter does not increase. • Capacity measured in “tons (of ice) per day” A “Ton” of refrigeration - definition: • Convert a ton (2000 lb) of 32 deg F liquid water to a ton of 32 deg F ice in one day. --The make-up water percentage is approximately 35%-45% which is high and being investigated --The typical chilled water flow is approximately 8,000-9,700 gpm during the cooling season and during 90-90 degree outdoor temperature. Other parts, such as valves, a loss of head gauge, surface washers, and a backwash pump, are used while cleaning the filter. • Energy costs reflect the overall cost of creating and delivering energy— including items such as power plant water use, site physical disruption and other environmental factors. 9 k Calories /h = 12661 kJ/h = 3. Here is a simple online Cooling Water Flow Rate Calculator Through Condenser which helps you to calculate the volume of water that gets heated per hour for the given heating wattage and used temperature. 1-2013 requirements and using good design practice for decisions where there are\ഠno requirements, leads to a chiller plant that will be quite good in annualized energy consumption - in kilowatt hours per ton-對hours. 4 gpm circulated per ton. entering air temperature. Gain the confidence you need to design a successful, energy-efficient chiller plant. The buildings competed against each other for chilled water flow.
