It sounds to me you have possibly one of 2 issues. Or maybe both. 1) The expansion valve might not be releasing enough refrigerant into the evaporator when at low RPM due to low pressure. 2) you are low on refrigerant.
The expansion valve can 'freeze' in a closed, open or partially open position. I'd get an A/C guy to look at it. The valve is about $30 CDN and refrigerant about $60 CDN. That is what it cost me to fix my similar issue a couple of years ago.
A far more expensive problem may be the compressor itself or the compressor clutch not operating properly.
