Temperature after replacement
Thread Content
Is it normal for the gas phase temperature at the top of the circulating water heat exchanger under normal load to be higher than the temperature of the condensate (return fluid), especially when there is also a chilled water heat exchanger for further cooling? The temperature of the vapor at the top of the tower is 70 degrees, the reflux temperature is 50 degrees, the temperature of the vapor after exchange is 55 degrees, and the temperature difference between the inlet and outlet of the circulating water is around 8 degrees. Is that how it was designed?
1. The temperature difference of the circulating water should be 8°C or 10°C, depending on the conditions of the circulating water system; if it is installed within the device itself, either 8°C or 10°C is acceptable. 2. If it is still in the gas phase at 55°C, what is the saturation temperature at the operating pressure? Is 50°C reflux a bit too high?
@ 2nd floor, same feeling~~~ A 5°C difference is a bit small
