Hi all,
Dont usually look after fridge equipment but today looked at problem with coldroom. leak reported from condenser. System is a fosters and the condensing unit is mounted on side of coldroom in kitchen. System operates on r404, suction pressure 45psi and the room temp ok (4c) ,but found ice build up on suction and all over compressor. The leak is from ice melting when comp cuts out when set temp is reached. Suspected problem with refrigerant charge so reclaimed and weighed in correct charge from fresh cylinder - same problem.
Condenser coil is clean , both fans are operating and desired temp is being reached. Could anyone explain this ice build up and how to correct it? Also comp sounds quite loud during operation.
thanks
