Hi Guys well I guess you are all madly shovelling snow in preparation for Christmas, quite different here, two days ago we had 38 c (100.4) and around 68% !!
Heat index 142 f

Time here is 4.08 PM and it has cooled down a bit (32 c (90 f) 70% RH) today and it is cloudy.
I never checked the head pressure those days but I have previously on hot days.
The system has two quite small 3 phase condenser motors, low fan is star, high fan is delta. I have set them up to switch between star and delta controlled by pressure switches.
The first fan is turned on around 200 PSI (R22) and the second fan starts as stage two of the control sequence. Then the control of the head pressure by switching between star and delta.
The plant usually runs between around 200 to 240 PSI depending on the ambient temperature. The highest head pressure I have seen it run at was
240-250 PSI.
The condenser is somewhat oversized and I designed it to keep the head pressure fairly low which it does.
I would not know sense I am not drinker, but to my knowledge Ireland is real beer drinker I have witnessed that three time times I have being there on the job, hell I can even imagine where the hell they put all that they consume!!!
HAVE A HAPPY ONE AND PROSPEROUS ONE MAY GOD BLESS ONE AND ALL
