Thanks for the replies! I know its the latest technological scroll type compressor used in most A/C units built today weather it be marine, aviation, auto or home units. It's also variable speed based on demand and temperature settings for the cabin. I have removed the frunk liner and to look at the compressor and its one of the smallest units I have seen in the industry but there is no data tags visable on it giving the BTU rating or operating voltage. Most of the ones I see in the aviation business are 24 volt DC but are belt driven and much larger and heavier. I am working on a A/C system for small vintage aircraft that do not have room for the large units and operate off of 12 volts DC. The compressor has been the holdup and if this unit operates off of 12vdc it could be just what we have been looking for. Something tells me its much higher voltage to keep the amperage draw down.
