Abstract
The present invention relates to a speed control system for hermetic compressors of the variable speed type, which uses a PMSM motor, containing a strategy for optimization, or minimization, of the electric current. Once the minimum current has been defined to meet a given demand for torque, it is applied to the hermetic compressor motor, which will operate at the maximum efficiency point for each load point.
Claims8
A method for increasing the efficiency of hermetic compressors applied in refrigeration and air conditioning, characterized by having an electronic converter, which executes at least one control algorithm to conveniently drive a variable speed hermetic compressor, said compressor being an integral part of a plurality of refrigeration systems, such as refrigerators and freezers for residential or commercial use, window-type or split-type air conditioners.
