How does an economizer work on a chiller
WebA common application of economizers in steam power plants is to capture the waste heat from boiler stack gases ( flue gas) and transfer it to the boiler feedwater. This raises the … WebRunning a single system on the chiller and checking the temperature differential across the evaporator (return minus leaving water temp) is also a quick means for checking for low flow, if the flow cannot be measured using a flow meter or there is doubt about the accuracy of the flow pressure drop measurement.

WebApr 12, 2024 · Indirect evaporative coolers use two separate air streams separated by the heat exchanger walls. The secondary air stream uses the evaporative process where water trickles down over air being exhausted from the building or by the use of outside air. This causes some of the water to evaporate and absorb heat from the primary air stream … http://www.doas.psu.edu/econ_column.pdf
