Webwith an entering condenser wate r temperature 35.0°F (1.7°C), below the leaving chilled-water set point. Because free cool-ing is not so free anymore, these new chillers lower … WebAnswer (1 of 4): No, quite the opposite. Water vapor (or whatever the substance) has latent heat which is expressed by the high velocity of its water molecules. Condensation …

at what temperature does water vapor in air condense? - Lisbdnet.com

Webwith minimum entering condenser water temperature below the leaving chilled-water set point. This is sometimes referred to as inverted or upside down operation. It can operate stably with an entering condenser wate r temperature 35.0°F (1.7°C), below the leaving chilled-water set point. Because free cool- A good rule of thumb is 2% kw/ton reduction per 1°F reduction in condenser water supply temperature. Assuming a constant 70% load or 350 tons, let’s compare the efficiency and power consumption with condenser water supply temperatures of 85°F and 65°F. Power consumption at these two points is: See more Fundamental to efficiency of a chilled watersystem is compressor lift. Lift, or head pressure, refers to the difference in refrigerant pressure between the condenser and the … See more With a constant temperature differential, reducing condenser water flow rate increases the efficiencyof the pumping and cooling tower system, while reducing the efficiency of the … See more Probably the most common method of controlling cycles is conductivity control. With the method, the conductivity of the condenser water is constantly measured. When it reaches a … See more In addition to design selections and strategies, operations and maintenance programs have a significant impact on overall water system … See more alcolu sc to charleston sc

Sustainable condenser water system strategies

WebFor water-cooled systems, lowering the condensing water temperature (condenser water temperature reset) is another opportunity for saving energy. In conventional systems, the condensing water temperature is set at a constant value of about 30°C (~85°F). ... Due to the large surfaces needed for heat transfer, the systems work with low water ... WebApr 2, 2012 · In summary, a much more efficient way to adjust to changing load characteristics or lower condenser water temperatures is to vary the speed of the chiller compressor motor, as opposed to adjusting vanes or other mechanical flow-control devices. alco managment maintenance assisstant salary
