im from norway ,pronounces english like an mental nutcase.
i have a never ending history with an accona freezer bench.customer claims the temperature isnt low enough only -13 celsius he wont -18. set temp is -22
.system is ,404a 1000gram ,danfoss sc12,te2 00 orfice .compressor and condenser is supposed to be in the funiture(bench) but is moved out to other room 27celsius ambient .7meter tubing 1/4" 3/8".it has a reciever as well.
first time suction pressure seemed high 1.8 bar gauge.and tev didnt compensate .called my refrigerant supplier, he recommended me to change tev and orfice .at that moment i didnt know it was fitted with orfice 00 (not sure if that is original)so when i told him compressor size and desired cabinet temp he suggested the 0x orfice .
after replaced tev and orfice 0x temp stay the same .but suction pressure is 1 bar gauge .the i have may overlooked is the condensing temp in the middle of the condenser pipetemp is 27celcius and headpressure is 12,5 bar (after reciever) and head pressure goes down when temp goes down in cabinet.sightglass is full and clean but liquidline is "cold" maybe 20 celcius
btw compressor is replaced filterdrier and burnout filter. flushed with nitro and in a long vacum
could the 0x orfice be to small to this evap ,no heat to reject or maybe condenser fit better ambients in the bench
or does it need exorcism?
