After adding up the two curves and obtaining the total cost curve, the optimum approach is at the minimum
20/6/2006· 1 ton = 12,000 BTU/hr. And 1 BTU/hr = .29 watts. However, if you put .29 watts into an electrically driven chiller you do not get 1 BTU of cooling out. You get more. You need to consider the coefficient of performance of the chiller. So. Step 1: Figure out how many tons of cooling is really produced annually.

25/1/2022· It is a dimensionless nuer. It can be calculated by any of the below formulae. You can calculate COC in three different ways. #1. COC = Silica in cooling water / Silica in makeup water. #2. COC = Conductivity in cooling water / Conductivity in makeup water. #3. COC = Make up water quantity / Blowdown water quantity.
12/3/2020· Thereof, how do you calculate gpm through a chiller? Multiply the fluid''s horsepower by 3960. If the chiller works at 25 horsepower: 25 x 3960 = 99,000. Multiply your answer by the pump''s efficiency. If the pump works at 80 percent efficiency: 99,000 x 0.80 = 79,200. Subsequently, question is, what is the formula for GPM?

17/5/2017· The Dutch engineers’ tower measured 34 metres, which at the time was a substantial achievement, but as engineering and construction abilities progressed, so too did the size of cooling towers. Today, each of 12 towers measures 115 metres tall – big enough to fit the dome of St Paul’s hedral or the whole of the Statue of Liberty, with room to spare.
The amount of water that is bled off by the water treatment system is usually less than or equal to the amount of water that evaporates. Therefore, the maximum normal water makeup for a cooling tower system is .06 gpm / ton, or about 2% of the nominal tower flow rate. The following chart specifies the Maximun Water Make Up requirement per model.
