Abstract:
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 (VM), the controlled voltage (VM) having a voltage frequency (φP) 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).
