Freezing room problem
Greetings,
I have a cold room at -18 degrees C that does not go bellow -11. Refrigerant R404a.
At first it had a leak that i fixed but now it does not go bellow -11. It goes to -4 quickly and after that slowly until around -11. Defrost at 4 hours, it doesnt get clogged with ice because there aint much humidity (products are sealed in packages).
Condenser its not clogged either i cleaned it.
Evaporator has 2 fans and its kinda too big for the actual room which its around 2.5x2x2.1m
On the low side it has 2.5bars and the evaporating temperature after condenser its 30-35 degrees C.
It freezes on return line almost before the compressor and it does not have a liquid separator on the low side.
Any advice will be of much help.
Thank you in advance.
