Condenser Water System Flow Test

Condenser %ater S&stem

Flow test in di'erent o(erating modes

Purpose:

be nearl! self balan"ing. # b!pass $al$e is pro$i%e% on le$el 20# to allow water to

re"ir"ulate insi%e the buil%ing %uring start&up so the "hillers "an "ome on line with

parallel are %ifferent with %ifferent pump "ur$es "ompli"ates this a little bit. The

s!stem will spen% a signifi"ant number of hours running with onl! one pump.

(riginall! the s!stem was to be pro$i%e% flow "ontrol $al$es on ea"h "hiller to ensure

ina%$ertantl! installe% instea%. The purpose of this test is to %etermin if the flow

or a non&issue. The! will be a problem if)

1. The pumps run out their "ur$es far enough that the! trip o$erloa%s

2. The pumps run out their "ur$es far enough to "a$itate.

3. The tube $elo"ities in the "hiller tubes are %ri$en high enough to ma*e

errosion a "on"ern.

4. The pump energ! use% when the pump runs out its "ur$e e+"ee%s the "hiller

The "on%enser s!stem "onsists of two %ifferent si,e% pumps in parallel pumping from
