linear motor, the linear compressor, method of controlling a linear compressor, refrigeration system and controlling a linear compressor system.

摘要

linear compressor (100) applicable to a cooling system (20), the linear compressor (100) a piston (1) driven by a linear motor (10), the piston (1) an offset distance controlled by a voltage electric controlled (VM) generating the controlled electric voltage (VM) a feedstream (iA) flowing in the linear motor (10) and having a voltage frequency (FVM) applied to the linear motor (10) and adjusted by a processing unit (22), the processing unit (22) configured to dynamically control the distance of displacement of the piston (1) in function of the variable demand of the cooling system (20), the linear compressor (100) being one resonance frequency, the linear compressor (100) characterized in that the processing unit (22) is configured to measure a feed phase (ΦC) of the supply current (iA) and a dynamic phase (ΦP) of the piston (1) linear compressor (100) being further configured processing unit (22) for measuring the difference between the feed phase (ΦC) and the dynamic phase (ΦP) and establish a measured phase (ΦPC) adjusting the processing unit ( 22) the controlled voltage (VM) to the value of the measured phase (ΦPC) is zero, so that the linear compressor (100) is dynamically kept in resonance throughout the variations in demand of the cooling system.
