Abstract

A variable capacity compressor and a starting method thereof. The variable capacity compressor includes a four-way valve having a suction gas distribution function and an idling chamber high-pressure injection function, thereby achieving a reduced manufacturing cost and an improved reliability incurred by the use of a validated component. Further, a boosting algorithm is applicable to obtain a driving source of the four-way valve in an initial parallel pressure state. In the variable capacity compressor comprising a plurality of compression chambers having different capacities and a four-way valve to distribute a suction refrigerant gas into the plurality of compression chambers, a starting method thereof comprises determining whether the variable capacity compressor is in an initial starting mode, and controlling the four-way valve to generate a pressure difference to move a piston of the four-way valve from an initial parallel pressure state if the variable capacity compressor is determined to be in the initial starting mode.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2005-15950 filed in the Korean Intellectual Property Office on February 25, 2005, which are hereby incorporated by reference in their entireties. technical field [0002] The present invention relates to a variable capacity compressor, and more particularly, to a four-way valve comprising a suction distribution function and a high-pressure injection function and designed to obtain a four-way valve in an initial balanced (parallel) pressure state A variable capacity compressor of a driving source, and a method for starting the variable capacity compressor. Background technique [0003] Cooling systems designed to cool closed spaces using a refrigeration cycle, such as air conditioners and refrigerators, include a compressor for compressing a refrigerant circulating in the closed circuit of the refrigeration cycle. The cooling capacity of the cooling syst...
