Title:

FREQUENCY- VARIABLE COMPRESSOR AND CONTROL METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2010/056002

Kind Code:

A1

Abstract:

The present invention discloses a frequency variable compressor, including a shell (100) defining an airtight space, an accumulator (900) temporarily storing refrigerant before introducing the refrigerant into the shell (100), a first compression mechanism unit (410) positioned in the shell (100), including a rolling piston (412), a cylinder (411), a refrigerant suction hole (410h), a refrigerant discharge hole (41 0d) and a vane, and compressing refrigerant, a second compression mechanism unit (420) positioned in the shell (100), including a rolling piston (422), a cylinder (421), a refrigerant suction hole (420h), a refrigerant discharge hole (420d) and a vane, and compressing refrigerant, a frequency variable motor (200) positioned in the shell (100) and transferring power to the rolling pistons (412, 422) of the first and second compression mechanism units (410, 420) through a rotating shaft (300), and a valve (700) controlling the flow of the refrigerant such that the first and second compression mechanism units (410, 420) compress the refrigerant by a twin rotary compressor type or a 2-stage rotary compressor type.
