Running control method for clockwise/counter-clockwise rotary compressor of refrigerator

Abstract

The control method for clockwise / counterclockwise rotation compressor in refrigerator includes the following stages: the first stage of judging whether the compressor rotates in the direction the same as that the command requires, and if so, maintaining the clockwise / counterclockwise rotation of the compressor; and the second stage of stopping the compressor before rotating the compressor in the direction the same as that the command requires, in case the compressor rotates in the direction opposite to that the command requires.

Description

technical field [0001] The invention relates to a clockwise / counterclockwise rotary compressor of a refrigerator, in particular to an operation control method thereof. Background technique [0002] Generally speaking, the refrigerating cycle acting on the refrigerator is generally divided into a forced refrigerating cycle for supplying cold air to the freezer and a weak refrigerating cycle for supplying cold air to the refrigerating chamber. [0003] Here, for the forced refrigeration cycle or the weak refrigeration cycle, since the lengths of their expansion structures are the same, the optimal refrigeration cycle cannot be realized according to the operation mode. There are technical explanations. [0004] Such as figure 1 As shown, such a refrigeration cycle generally includes a compressor (1), a condenser (2), a first evaporator (F-EVA), a second evaporator (R-EVA) and a thin tube (3), the compression Machine (1), which can suck the low-temperature and low-pressure re...

AI Technical Summary

Problems solved by technology

[0011] However, the problem with the above method is: in controlling the compressor to rotate clockwise or counterclockwise, there is no way to confirm whether the compressor is rotating in the controlled direction, so the compressor may malfunction, resulting in Refrigerators operate less efficiently and also increase power consumption
