Abstract
Official abstract text for this publication.
A linear compressor ( 100 ) applicable to a cooling system ( 20 ) includes a piston ( 1 ) driven by a linear motor ( 10 ), the piston ( 1 ) having displacement range controlled by means of a controlled voltage (V M ), the controlled voltage (V M ) having a voltage frequency (φ P ) applied to the linear motor ( 10 ) and adjusted by a processing unit ( 22 ), the range of piston ( 1 ) displacement being dynamically controlled in function of a variable demand of the cooling system ( 20 ), the linear compressor ( 100 ) having a resonance frequency, the processing unit ( 22 ) adjusting the range of piston ( 1 ) displacement, so that the linear compressor ( 100 ) will be dynamically kept on resonance throughout the variations in demand of the cooling system ( 20 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling a linear compressor ( 100 ) of a cooling system ( 20 ), the linear compressor ( 100 ) comprising a piston ( 1 ) driven by a linear motor ( 10 ), the piston ( 1 ) having a controlled voltage (V M ), the controlled voltage (V M ) having a voltage frequency (f VM ) applied to the linear motor ( 10 ) and adjusted by a processing unit ( 22 ), the controlled voltage (V M ) generating a feed current (i A ) that circulates in the line…
