  1. 2 stage industrial ammonia refrigeration use the system of continuous screw compressor. I worked with some made by York. I can only see them on commercial boats with generators.
    Danfoss compressors are still the standard for cruising sailboats.
    On a recent jungle trip (near Victoria Falls) I used Peltier effect coolers (no moving parts), min temp 36F, same energy usage as conventional high efficiency, less weight. There are several manufacturers. The major drawback is no freezer, no ice and one speed slow cooling.
