Something to keep in mind will be the internal flow of the gas to liquid. If you can tilt it so the gas will enter the high side and gravity will help it flow as it is converted to a liquid. The compressor won't do the job of pushing the liquid up hill, or across a condenser as well as having a little help from gravity. Check on any factory installation, you'll see it enters at the top of the condenser as a high pressure gas, and exits at the bottom of the condenser as a high pressure liquid. If you want to map out a system so it's easy to understand, draw a diamond. Going around the diamond clockwise, starting at the top, label the top point, Compressor, next point, Condenser, next point, expansion valve or orfice, (can be either) and the last point of the diamond, evaporator. You now have a simple A/C system. They all work in this manner. Sniper
