Hi members,
In absorption chiller, steam condensing temp. in
generator becomes negative and sometimes very low at partial load operation. Matter is how to remove it smoothly because the receiver tank pressure will peak out at the equivalent pressure even if you use a vacuum pump. Trane/York IOM recommend to install a vacuum breaker in the generator steam side. It looks very simple and low-cost solution.
My concern is corrosion of generator and condensate piping of the chiller because steam condensate is possible to cause corrosion w/o much air(oxygen) and it must be worse by this vacuum breaking.
Does anybody have an experience of the vacuum breaking and corrosion ?
