Current issue

[mad fridgie]

Hi,mad, the lower volumetric efficiency, mass flow reduction related to system efficiency, not the compressor load. The running or operating amperage of a refrigeration or air conditioning compressor is directly related to the load put on the compressor motor. One method of motor loading would be the mechanical load. the relatively small amount of friction created by the matched components of the compressor, such as the crankshaft to bearings, connecting rods to the crankshaft, pistons to cylinders, etc. Another method of motor loading would be the pressures entering and exiting the compression chamber, basically the suction and discharge pressures.I have another thought. As per the ohms law, Current and resistance is inversely proportional. When increased the discharge temperature will cause to increase the temperature of conductor (winding) and it might be increased the winding resistance. It may affect the reduction of the current………………………….

Yes and no.
