Abstract
A method for protection and diagnosis of a linear compression (2), the linear compressor (2) including at least one electronic control (11), the protection method being configured to perform the following steps at each work cycle of the linear compressor (2): detecting a suction time (ts) of the linear compressor (2); detecting a compression time (tc) of the linear compressor; calculating, after the step of detecting a compression time (tc) of the linear compressor, a decision parameter (ΔT) equivalent to the difference between the previously detected suction time (ts) and the compression time (tc).

Method for protection and diagnosis of a linear compressor (2), the linear compressor (2) comprising at least one electronic control (11), the protection and diagnosis method (1) comprising, at each work cycle of the linear compressor (2), the steps of:
- detecting a suction time (ts) of the linear compressor (2);
- detecting a compression time (tc) of the linear compressor (2);
- subsequently, calculating a decision parameter (ΔT) equivalent to the difference between the suction time (ts) and the compression time (tc).
A method for protection and diagnosis of a linear compressor (2) that comprises at least one electronic control (11), the protection and diagnosis method comprising, at each work cycle of the linear compressor (2), the steps of:
- detecting a suction time (ts) of the linear compressor (2);
- detecting a compression time (tc) of the linear compressor;
- subsequently, calculating a decision parameter (ΔT) equivalent to the difference between the compression time (tc) and the suction time (ts).
System for protection and diagnosis (13) of a linear compressor (2), the linear compressor (2) electrically associable to a feed source (V) and comprising at least:
- an electronic control (11) provided with at least one internal memory (10), the internal memory (10) being capable of storing a decision parameter (ΔT) of the linear compressor (2) at each work cycle of the linear compressor (2), so that:
- the protection and diagnosis system (13) determines the decision parameter (ΔT) from the difference between a suction time (ts) and a compression time (tc) of the linear compressor (2);
- and
- the system interrupts the electric association to the feed source (V) and the linear compressor (2) if the decision parameter (ΔT) is lower than a normality range or higher than a maximum operation limit (B).
