A method for changing the capacity of an air-conditioning compressor

Abstract

The invention belongs to the technical field of air conditioning compressors, in particular to a capacity changing method of an air conditioning compressor. The capacity changing method adopts an adjusting module, and the adjusting module comprises a worm, a worm gear and a second pushing block; the worm is rotationally connected inside a connecting shaft, the middle of the worm is connected withthe worm gear in a cooperating mode, and the worm gear is rotationally connected in the connecting shaft; and an inner hexagonal groove is formed in one end of the worm gear, the second pushing blockis arranged inside one end of the connecting shaft in a sliding mode, and the lower end of the second pushing block is screwed with the worm. According to the capacity changing method of the air conditioning compressor, rotation of the worm is used for achieving the axial movement of the second pushing block along the connecting shaft; the upper end of the second pushing block is arranged to be aninclined plane corresponding to a first pushing block, and the first pushing block and the second pushing block are connected with each other in a joggling mode and are capable of achieving relativesliding; the inner hexagonal rotating worm gear is used, the second pushing block is pushed upwards, the first pushing block moves outwards, the driving radius of a connecting rod is increased, then the travel of a piston is increased, and the capacity of the compressor is changed; and different capacities are adopted for different use environments, and the applicability of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning compressors, and in particular relates to a variable capacity method of an air-conditioning compressor. Background technique [0002] Inverter air conditioners add an inverter to the structure of conventional air conditioners. The compressor is the heart of the air conditioner, and its speed directly affects the efficiency of the air conditioner. The frequency converter is a control system used to control and adjust the speed of the compressor, so that it is always in the best speed state, thereby improving the energy efficiency ratio. [0003] In the existing inverter air conditioner, due to the large number of control circuit components and they are related to each other, once a fault occurs, it is difficult to repair and the price is high; for different loads, the use efficiency is low, and the efficiency of the compressor cannot be used efficiently. . A method of manually adjusting ...
