Problems solved by technology

[0007] However, in the case of a conventional compressor using a high-speed two-pole motor, there is a problem that the operating noise of the compressor is excessively increased due to vibration generated during high-speed rotation of the motor
[0008] As a solution, although it is problematic to provide a compressor with a low-speed motor (such as a four-pole motor) with two or more poles having a commercial rotation speed of 1500-1800 rpm to reduce the operating noise of the compressor, Because such reduced motor speed tends to lower the compression performance of the compressor, making it impossible to perform smooth refrigerant compression operation

Abstract

One aspect is to provide a compressor capable of reducing operating noise by using a low-speed motor without impairing compression performance. The compressor includes: a hermetic casing; a compression unit having a compression chamber to compress refrigerant, a drive unit in the form of a low-speed motor having four or more poles and providing the required power to compress the refrigerant; and a feeder for increasing the amount of refrigerant to be introduced into the compression chamber.

Description

technical field [0001] The present invention relates to compressors, and more particularly, to compressors that reduce operating noise without deteriorating compression performance by using a low-speed motor. Background technique [0002] Generally, a refrigeration cycle employed in refrigerators, air conditioners, etc. includes: a compressor that sucks and compresses low-pressure refrigerant and releases refrigerant in a high-pressure state; and a condenser that condenses high-pressure refrigerant from the compressor. an expander that expands the condensed refrigerant from the condenser; and an evaporator that evaporates the expanded refrigerant from the expander to transfer heat from the refrigerant to the surrounding air. Here, the compressor, condenser, expander and evaporator form a closed circuit through refrigerant pipes. [0003] Therefore, the refrigerant circulating in the refrigeration cycle radiates heat to the surroundings when it condenses in the condenser, an...
