HI There,
Just woud like some clarification whether or not i am taking the measurments right to calculate SC and SH on this system in the pitcures.
Fridges picture - You can see both the units. There is 2 units for the Freezer and 2 for Fridges. This set up is in a shipping container the there is 3 comaprtment Freezer, Fridge, Drystore(thiis is cooled by an A/C
In The photos i have put red marker on them to show where i am taking these measurments from hopefully they are correct.
These units are designed to operate at 43degC but today was 50degC+ so they are just continually running as they cant pull the cabnets down to temp. I have notice that there is not much air flow behind the units also. Are these two factors what woudl cause high head pressures? The fridges were up about 370psig and freezers were about 300psig.
Any info woudl be great.
