Patent ID: 7441413

Claim:
A refrigerator comprising: a plurality of evaporators comprising at least one low-pressure-side evaporator and at least one high-pressure-side evaporator; a path change device to change a flow path of a refrigerant between the low-pressure-side evaporator and the high-pressure-side evaporator, the path change device having a simultaneous opening stage to simultaneously establish refrigerant flow paths respectively communicating with the low-pressure-side evaporator and the high-pressure-side evaporator during the path change; and a controller to control the path change device such that the simultaneous opening stage established when the flow path of the refrigerant is changed from the low-pressure-side evaporator to the high-pressure-side evaporator is longer than the simultaneous opening stage established when the flow path of the refrigerant is changed from the high-pressure-side evaporator to the low-pressure-side evaporator.
