all dears.
good day
may you all please get me some suggessions for the following?
i have installed one PHE for chilled water generation and it was running fantastic for last 8 months .
but for last few days it is not giving proper and of course rated parameters.
the details of the PHE are as follows.
alfa laval PHE ( semiwelded NH3 to water application)
125 TR at the rate of 50 CMH and
water in = +8 Deg C
water out = + 2 Deg C
EPR of danfoss is installed to control the evaporation temp. at -1 Deg C
no oil is stuck in the phe or the surge drum.
compressor is giving a capacity of 133 TR at - 1 to +40 Deg C
the problem i am facing is
even the EPR is there ,the evaporation temp. is falling down to
-10 Deg C which i fear will cause the water to frost in side of the plates and will crack the plates.
i have carried the following activities.
1.cleaned the filter of the EPR
2.replaced the CVP
3.drained out the oil; but didnt get any oil trace in side of the system
i am expecting smoe kind of suggessssions from you experts.
have a nice time ever.
waiting eagerly,
priti:)
