Abstract
The invention provides a refrigerator having a two-stage compression compressor capable of performing efficient cooling of a both a refrigerator compartment and a freezer compartment. A high-pressure delivery outlet of a two-stage compression compressoris connected to a condenser, the condenseris connected to a three-way valve, a first outlet of the three-way valveis connected via an R capillary tubeand an R evaporatorto an intermediate-pressure intake of the two-stage compression compressor, is connected and via an F capillary tubeto an F evaporator, the F evaporator is connected to a low-pressure intake of the two-stage compression compressorvia a low-pressure suction pipe, the three-way valvecan switch between a simultaneous cooling mode and a freezer mode, and when in the simultaneous cooling mode the interior temperature of the refrigerator compartmentfalls to a predetermined temperature it switches to the freezer mode.
