1. The Danfoss 12v compressor and power module - the module controls the compressors RPM, the cooling fan on the condensor and the low battery cut-out. 2. The existing copper lines from the fridge\'s evaporator - they are work hardened and I did want to move them too much. I wrapped the capillary and return line together and insulated them so that the capillary could take advantage of the residual return lines left over capacity to extract some more heat from the feed. 3. The condensor - requires a fan that can move 100cfm of air. 4. The schrader valve on the low side of the system for evacuating and charging. I had intended to add a valve on the hi-side but left it out in my haste to complete the project for a two week trip in September.
