Intriguing. But.. you can burn out the compressor if you run with no or little gas, as the compressor itself cannot dissipate sufficient heat. It needs gas to carry the heat away to the condensor. The condensor is part of the cooling system for the compressor.. Also, even while there is little gas, it can still produce ice, if you look at the phase chart of the gas. The ice is usually closer to the evaporation valve.
