Here is a video of my compressor testing. One thing that I am not sure about is how much R134A refrigerant I should charge the system with. I am also not completely sure what the high or low side pressures should be normally. I know that the high side pressure should not go above 350 psi. Overall the cool liquid does get rather cold. I need to get a better thermocouple because I believe mine is not very accurate.
