Abstract:
1. A refrigerator, comprising: a compressor; a condenser; a first evaporator; a second evaporator, the compressor, the condenser, the first evaporator and the second evaporator being connected to each other in series to perform a refrigeration cycle; a first expansion unit reducing a refrigerant pressure level to a first pressure level such that a refrigerant flows into the first evaporator; a second expansion unit reducing the refrigerant pressure level to a second pressure level such that the refrigerant flows into the second evaporator first and second fans; first and second compartments to transfer heat to the first and second evaporators by the first and second fans, respectively; a first refrigerant path provided between an outlet of the compressor and an inlet of the second evaporator; a third expansion unit provided between an outlet of the condenser and an inlet of the second evaporator; a first path switching unit switching a first refrigerant path such that the refrigerant, flowing from the condenser into one of the first and third expansion units, flows to a remaining one of the first and third expansion units; a second refrigerant path provided between an outlet of the first evaporator and an inlet of the compressor; and a second path switching unit switching the second refrigerant path such that the refrigerant, flowing from the first evaporator into one of the second expansion unit and the compressor, flows to a remaining one of the second expansion unit and the compressor.
