Air supplementing channel, compressor and air conditioner

Abstract

The invention provides a supplementing channel, a compressor and an air conditioner. The air supplementing channel is used for supplementing air and increasing enthalpy of a rotor type compressor andcomprises a first channel and a third channel which are sequentially communicated, the first channel is communicated with an air supplementing pipe of the compressor, the third channel is communicatedwith a compression cavity, and the compression cavity is communicated with the air supplementing pipe through the first channel and the third channel; and the first channel is arranged on a flange part or a partition plate part, and the third channel is arranged on a roller. The air supplementing channel is used for air supplementing and enthalpy increasing of the rotor type compressor and suitable for a single-cylinder compressor or a double-cylinder compressor, supplemented air is introduced into the compression cavity through the first channel and the third channel through the first channel and the third channel in the partition plate or the flange part, and an outlet is formed in the optimal position; and an air supplementing starting position is arranged at the end, close to a high-pressure cavity, of the roller and the inner wall face of an air cylinder, and the ending position is achieved when the roller rotates to the compression cavity pressure to reach the air supplementingpressure position, so that the air supplementing and suction backflow problems are solved, and the air supplementing effect is good.

Description

technical field [0001] The disclosure belongs to the technical field of compressors, and in particular relates to an air supplement channel, a compressor and an air conditioner. Background technique [0002] In the prior art, when conventional compressors are used in high-temperature refrigeration and low-temperature heating environments, such as heating in the Middle East or refrigeration in northern regions, due to the harsh environment and poor cooling and heating effects, the structure of air supplementation and enthalpy increase is often used to solve the problem. . Under high-temperature refrigeration, the gas-state ratio of the refrigerant entering the evaporator is reduced by supplementing air through the middle of the system, thereby reducing the enthalpy of the refrigerant entering the evaporator and increasing the cooling capacity of the air conditioner; The amount of refrigerant entering the compressor increases the heating capacity. [0003] Conventional air s...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved in the present disclosure is that the unreasonable design of the air supplement channel of the compressor in the related art leads to the phenomenon of air supplement backflow and suction backflow, and the air supplement effect is poor, thereby providing an air supplement channel, a compressor and an air conditioner
