Pressure detection switch, air conditioner control method, device, air conditioner and storage medium

Abstract

The embodiment of the present invention relates to a pressure detection switch, an air conditioner control method and device, an air conditioner and a storage medium. The pressure detection switch includes: a pressure tube, the pressure tube is provided with a first open end and a second open end; at least one pressure-bearing A piece is arranged in the pressure tube, the pressure-bearing piece and the first opening end form a first airtight chamber, and the pressure-bearing piece and the second opening end form a second airtight chamber; the pressure-bearing piece forms a second airtight chamber; The pressure piece deforms or displaces based on the pressure difference between the first airtight chamber and the second airtight chamber; the conduction piece is directly or indirectly connected to the pressure-bearing piece and follows the pressure-bearing piece The deformation or displacement is connected to the first contact piece and / or the second contact piece. The pressure detection switch provided by the present invention can detect the start-up condition of the air-conditioning compressor, control the start-up of the compressor, reduce the start-up current impact, and prolong the service life of the air-conditioner And has the advantage of low cost.

Description

technical field [0001] The embodiments of the present invention relate to the field of air conditioners, and in particular to a pressure detection switch, an air conditioner control method and device, an air conditioner, and a storage medium. Background technique [0002] At present, due to the advantages of low cost and high reliability, mechanical air conditioners are still popular and widely used in countries with relatively backward economies such as Africa or Southeast Asia. [0003] However, because the mechanical air conditioner does not have electronic chips, motherboards and timing functions, when the pressure on both sides of the suction pipe and exhaust pipe of the compressor of the mechanical air conditioner is balanced, the compressor starts, and the starting current will exceed 4% of the rated current. -7 times; when the pressure on both sides of the suction pipe and discharge pipe of the compressor is unbalanced, the compressor needs a larger starting current ...
