Measure in a carrier 30hk chiller, 2 circuits, each with a 40HP 06E compressor, R22, water cooled condenser.
The high pressure gauge is connected to compresssor head, and it is 1 bar( about 15PSI) higher than measuring from condensor(16bar vs. 15 bar) .
I remember design book said that pressure drop in discharge line is expected not excess 2 F saturated temp lost. but 1 bar drop is about 5F lost
Is it a design bug?
