Compressor, control method of compressor and air conditioning unit

Abstract

The invention provides a compressor, a control method of the compressor and an air conditioning unit. The compressor comprises a cylinder module and a motor module. The cylinder module comprises a first cylinder and a second cylinder arranged in parallel or in series; and the first cylinder is provided with a normal working state and an unloading working state. The motor module comprises a motor piece, and a winding control piece electrically connected with the motor piece; the motor piece is connected with the cylinder module, and is used for driving the cylinder module to operate; and the winding control piece is used for controlling the electrification winding number of each phase of windings of the motor piece. Through the technical scheme, the compressor can achieve a wider frequency operation range, meanwhile, can achieve the better energy efficiency in all frequency bands under the precondition of minimizing the refrigeration output quantity, is quick and stable in switching, saves the electricity, improves the comfort, and prevents the cold waste.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a compressor, a control method for the compressor, and an air conditioner unit. Background technique [0002] The variable capacity compressor adopts multi-cylinder variable capacity technology, and has at least one compression cylinder (referred to as variable capacity cylinder) that can support the normal operation state and unloaded state, and at least one constant operation compression cylinder (non-variable capacity cylinder). When the cooling output of the compressor is too large, the output of cooling capacity can be reduced by reducing the operating frequency and controlling the unloading of the variable capacity cylinder, or when the compressor is operating in a frequency range with low efficiency, the variable capacity cylinder can be unloaded and the compression can be increased The operating frequency of the compressor can be increased significantly, t...
