Hello every ones it is my first post and i'm a french speaking guy, so...
We having a lot of problem with our Hvac system since a long time. Almost 3 years ago, a tech. came over while we were in Rotterdam getting ready to work in Angola. NB: I am on an oil rig. Any way , the guy change filters and been new on the rig and quit busy at the time. i did not have any question then.
We worked in Africa and keep the place cool enough. But for a long time all 4 compressors are going steady. I am not use to that type of system, but i beleive the heat exchange ratio is no long efficient, there is about 2 deg. f. in differential across the evaporator, it is about the same across the air handler coil. I would like to now if it is sufficient and it is the way it should be, or if not how can we resolve that problem. Also i should say the system shotdown on low saturated suction pressure, we tought a leak low in gas and add some and add some more and... Something is wrong somewhere.
Thanks to whoever can translate that.
