My advice would be, stay well away from GFCI circuits and Refrigeration/Aircon circuits, as far as mixing the two go.
It will only end in tears.
Mike that is not a choice under the NEC, currently the NEC requires GFCI protection on all 125 volt 15 & 20 amp commercial kitchen receptacles to have GFCI protected, many of these circuits will feed refrigeration equipment.
In dwelling unit Garages and basements GFCI protection is required and currently there is an exception for appliances in a dedicated space. When the 2008 NEC comes out the exceptions will be gone, if you place a spare freezer in the basement it will be GFCI protected.
The point is as far as the NEC is concerned it does not mater what your plugging into the circuit it only matters where there receptacle is located.
The one exception is for ice melting equipment as it has a high leakage current by design.
One last thing, according to the NEC hand book they do not believe it is the compressor causing the false trips, they believe it has to do with the electric defrost circuits in many refrigeration appliances.
