Power variable device of scroll compressor

Abstract

The invention discloses a power variable device of a scroll compressor, which comprises a shell; a moving turbine disc which is arranged inside the shell and provided with a spiral turbination; a fixing turbine disc which is provided with a spiral turbination, combined with the moving turbine disc to form a compression chamber, and openly provided with a first influx which leads refrigerant gas flows into the compression chamber at one side; a second influx which is openly arranged at the other side of the fixing turbine disc at a position staggered in a certain angle opposite to the first influx by taking the center of the fixing turbine disc as origin; and an opening and closing device which is arranged at an inlet end of the second influx to open and close the second influx. The invention can change the compression power for compressing the refrigerant of the scroll compressor, so that the compressor can operate most properly according to particular conditions, and the electric power consumption and the manufacturing cost can be reduced through simple power variations.

Description

technical field [0001] The invention belongs to a scroll compressor, in particular to a scroll compressor power variable device which can easily convert power, greatly reduce power consumption, and reduce manufacturing costs. Background technique [0002] Usually, the compressor converts electrical energy into kinetic energy, and uses the kinetic energy to compress the refrigerant gas. The compressor is the core element of the refrigeration system. According to the compression mechanism of the compressed refrigerant, it can be divided into various types such as rotary compressors, scroll compressors, and reciprocating compressors. Refrigeration systems using compressors are suitable for refrigerators, air conditioners, shop windows, and the like. [0003] The scroll compressor transmits the driving force of the drive motor to the movable scroll, makes the movable scroll mesh with the fixed scroll, performs a rotary motion, continuously sucks in refrigerant gas, compresses i...

Problems solved by technology

[0009] In addition, since there is only one inlet 390, the existing scroll compressor always operates under the same conditions and the same power, which sometimes causes unnecessary power consumption

If it is necessary to perform the most appropriate operation according to the specific conditions, it is necessary to equip an additional scroll compressor, which increases the manufacturing cost
