WebIf a pump doesn’t have a sufficient pump head, it won’t be able to deliver the water flow rate as promised. The water flow rate (eg: gpm, m3/s, L/s) of a pump is always stated based on a given pump head. For example, when a pump has a water flow rate of 1000 gpm at 20 meters of head, it means that the pump is able to deliver 1000 gpm of ... WebMay 1, 2002 · The 2 GPM/ton evaporator flow rate is a system with a 12 degree delta T (i.e. 44 degree supply water and 56 degree returned to the chillers). ... A low delta-T indicates …

WebJul 15, 2014 · Your CHW supply is 10°C, your supply air is 19°C and you have an air supply-return air differential of 11°C. With the same air and CHW flow rates, it would stand to reason that if you provide CHW at 3°C (consider a 10-20% glycol mix) you could achieve a supply air temperature of 12°C and therefore a room (return air) temperature of 23°C. WebNov 10, 2008 · The thermal energy equation (Q x Δ T) provides the insight on why low Δ T has such a detrimental affect on CHW plant capacity and efficiency. A chiller's cooling output is proportional to Q x Δ T, so producing rating tonnage is contingent on having either the design Δ T and design flow (Q) or on having an increased flow to offset the low ΔT. candida diagnosis and treatment
