Hi Chaps,
Does anyone have a pipe size chart for R407c refrigerant, coz i have a Denco unit which was commissioned back in 2008 with 25kg of refrigerant. i think this is wrong as the gauges tell me a different story. I've checked the pipe run and it is 128meters roughly from indoor to oudoor and back again. The pipe size is 1" 7/8 and 5/8" i have just reclaimed 24kg. Pressure tested and vacced and re-charged with 32kg, i bomb charged the system till i had a full sight glass and then trim charged. The problem is i am only getting 14bar discharge pressure and 3.5bar SUCTION pressure with both COMPRESSORS running. I have checked the FSC and i would of thought that with the outside temperature at -0degrees today the FSC would not be working at full speed. Can anyone help........:mad:
Cheers
