Dec 16, 2013· FYI I do not have too much experience doing cooling tower designs. I'm looking to replace an existing cooling tower (250 tons) and add a bypass valve for the condensing water. What should the bypass valve and pipe be sized for? (full flow of the cooling tower, minimum flow of the chiller, or ??) When going into bypass mode how should the pumping problems be addressed when changes in …

In practice, the temperature difference between cooling water and steam is about 10°C to 15°C. For example, if the cooling water is at 20°C, the condenser temperature is about 35°C and corresponding saturation pressure is 0.006 MPa. The corresponding thermal efficiency of the cycle would be 32% (refer to Figure 3.). If the cooling water is .

This term refers to the temperature difference between the leaving process fluid and the entering service fluid. If air is cooled from 300 F to 100 F using 90 F cooling water, the air temperature approaches the water by 10 F (100 – 90 = 10). Such a heat exchanger is said to have a "10 F approach temperature."

Too much flow is indicated by a cooling water outlet temperature only a few degrees above the inlet. This unbalanced flow condition leads to higher pump energy consumption and distant or elevated areas that are often starved for water. Higher cooling water return (outlet) temperatures result in lower cooling water consumption.
