ONE DAY WHILE TAKING ROUND, YOU FOUND OUT THAT THE TEMPERATURE OF FISH ROOM IS NOT NORMAL I.E ITS HIGH. NOW THE QUESTION IS HOW COME OTHER ROOM TEMPERATURE IS NORMAL WHILE TEMPERATURE OF ONLY FISH ROOM IS HIGH.
THE REASONS CAN BE MANY BUT BEFORE GOING THROUGH DETAILING LETS GO INSIDE THE REFRIGERATION ROOM AND CHECK THAT OUT DID OUR FRIEND CHIEF COOK FORGOT TO CLOSE THE DOOR OF THE FISH ROOM PROPERLY OR NOT :P. IF DOOR IS OK, THEN CHECK FOR FOLLOWING REASON :-
- THE EVAPORATOR COIL IS ICY.
- FAN ABOVE EVAOPORATOR COIL IS NOT WORKING.
- EXPANSION VALVE IS COVERED WITH ICE.
- THE SOLENOID VALVE MIGHT BE FAULTY.
- LOAD ON THE FISH CAN BE MORE CAUSE OF MORE AMOUNT OF STUFF INSIDE THE ROOM.

How expansion valve can covered with ice?
If the orifice of the expansion valve is chocked due to moisture as the moisture will become ice then the refrigerant will not be passed and gets accumulated in suction of the TEV and hence the cool refrigerant will cool the air and moisture outside of the expansion valve leading to icing of expansion valve.
