Water source heat pump trouble
Im not the greatest at heat pumps but can try and get by... Ive got one that is going off on high head. It starts for a few mins. completely fine, then while the suction stays the same the head pressure starts going up till it trips off on high head. I have good fan/compressor amps, and a clean filter. Its pretty much a new facility with a copper supply and return loop so I am kinda ruling out issues with water restrictions...? I havent taken any subcool/superheat calcs because i didnt have my clamp on me, but am I on the right track to think possible overcharge? Thanks
