| Capacity is measured by weight of the refrigerant charge.
"Pressures" are determined by many things, - Temperature, compressor speed, evaporator size and air flow, condenser size and air flow, cabin and suction pipe insulation, refrigerant type, expansion valve/oriface tube type, etc, etc.
I suggest you get some training if you are serious about this. At a minimum, you should limit your experiments to machinery you can live without...before you kill your entire fleet of air conditioners. | |
