    My unit has no access ports on the gas side, a EEV and no rev valve. But it does defrost the OD coil good.

    They do use CO2 in cars and yes it runs at high Pressure. Over 1000 psi. But it looks to me that it is coming on strong into the Residential and commercial a/c markets. Because it has no effect on Global warming and no effect on ozone depletion. Plus the manufactures are making "closed loop" refrigerant systems so no field refrigerant piping is needed.
