Hey, I didn't know we published a piping handbook.
People of Piping design: I am writing to you because I have some doubts about an instalation of a flooded refrigeration system with ammonia. The main problem seems to be in the pipe arrangement of a flooded evaporator (plate evaporator). It is a package for cooling Glycol. This client of mine has a lot of this package refrigeration systems and one of them does not have the same performance than the others who are practically the same design. One of the diferences is on the return line of the evaporator to the suction acumulator. This reurtn line goes above the control level of liquid like about 5". The plate heat exchanger is about 10 feet away form the acumulator, and the return line from this heat exchanger to the accumulator goes up from the heat exchanger to obtain a 2% inclination to the acumulator. Which means that when the equipoment is off, the liquid entraped in this line will go to the accumulator. Since the equipment doesnt have the same performance as the other package inastalled in my client plant. We think that the fact that this line has to go up in order to achieve the 2% inclination has something to do with the performance. What are your thought regarding this matter.
Also we are very intersted in adquiere your piping handbook, because we think that some of this problema can be solve using this literatura. Is that true?, How much does it cost?, and how can I order it?
Best regards and I hope to hear from You soon
