When you have determined the cooling capacity and compressor size, the next step is to consider the energy requirements and source. A typical constant-cycling system, using a popular Danfoss compressor, will draw around 7 amps (A) at 12 volts direct current (VDC) when running. If it cycles 30 minutes per hour, it will require 39 Amp Hours amp hours (AH) per day (7/2*24). A typical cold-plate system, drawing 35 Ampsamps in the cool-down phase, and cycling for two straight hours per day, will require just 3 AH /day (35*2/24). Overall, a cold-plate system is far more energy efficient, but requires a heftier energy source (larger DC system or engine) when it is running.
