Dear RE members,
While conducting performance test of watercooled DX screw chiller in factory I have following observations.
Charged less than spec.( R& D)
Capacity is less by 3%
Discharge/suction pr. as per design
subcooling 5 deg C
Suction superheat is @ 3 deg C.
Discharge superheat 27 deg C.
I need to know do I have to charge additional gas or not?
Since suction superheat is low if I open TXV my capacity will be dropped.
Pl. suggest solution.
Thanks in advance.
