Mechanical thermal expansion valve.
Most autos use a bleed orifice. There really isn't much you can do to improve the efficiency of a fixed orifice system.
For example, a cheap window unit air conditioner, it uses a fixed orifice.
But those window units run the compressor at a fixed speed so they are fairly efficient. Compared to vehicles that are all over the place for rpms.
