Abstract
A method for protection and diagnosis of a linear compression including at least one electronic control. At each work cycle of the linear compressor, the protection method includes detecting a suction time of the linear compressor; detecting a compression time of the linear compressor; and calculating, after detecting a compression time of the linear compressor, a decision parameter equivalent to the difference between the previously detected suction time and the compression time.
