Condenser head loss
WebJul 3, 2006 · At 65°F entering condenser water temperature (ECWT) and 40° evaporator chill water temperature, the pressure difference in the R-123 machine is 4.5 psi. The pressure difference in the R-134a machine is 28.9 psi. It is this lift in both chillers that can be beneficial or detrimental if not properly maintained. WebIn systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In so doing, the latent heat is released by the substance and transferred to the …

WebAnswer: Feet in Head = 8.5 PSI X 2.31ft./PSI = 19.64 ft. Step 4: Determine the Static Head (Open Systems Only) The static head is simply the total height that the pump must lift the fluid. It applies only in open systems. Remember that the static head is the difference in height that the pump will be required to provide. http://www.titanfci.com/docs/technical-data/strpdc.pdf
