Problems solved by technology

However, if the height of the wrap becomes higher or lower than a predetermined level in a state where the drive motor is driven at a low speed such as a speed lower than 35 Hz, the scroll compressor may have decreased performance.

Abstract

A scroll compressor wherein a value obtained by multiplying a wrap height by a driving speed is controlled to be within a range of 500 - 1000mmHz at a low speed driving (less than 35Hz). The wrap height of the scroll compressor, and the driving speed are set to be optimum, thereby preventing the scroll compressor from being operated at a speed excessively lower or higher than a predetermined driving speed. Therefore, the scroll compressor is allowed to run at an optimally low speed relative to the height of the scroll and the compressor and the refrigeration cycle device of the compressor have the enhanced performance.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to a scroll compressor capable of being driven at a low speed lower than 35 Hz. Background technique [0002] The scroll compressor means a compressor that compresses refrigerant gas by changing the volume of a compression chamber formed by a pair of scrolls facing each other. Such scroll compressors have higher efficiency and lower noise than reciprocating compressors or rotary compressors. In addition, such scroll compressors are widely used in air conditioners due to their small size and light weight. [0003] Scroll compressors are roughly classified into low-pressure type and high-pressure type according to the pressure of the refrigerant filled in the internal space of the airtight container. In the low-pressure type scroll compressor, since a suction pipe is connected to the inner space of the hermetic container, the refrigerant is indirectly sucked into the compression chambe...
