Disclosed are a three-door multi-temperature-zone refrigeration system with the rapid-freezing function and a refrigerator with the same and a control method thereof. The three-door multi-temperature-zone refrigeration system comprises a compressor, a condenser and a drier and filter; the condenser and the drier and filter are connected with an outlet of the compressor in turn; an outlet of the drier and filer is divided into two branches, wherein one branch is connected with a cut-off electromagnetic valve, a refrigeration capillary tube and a refrigeration evaporator in turn and the other branch is connected with an inlet of a bi-stable electromagnetic valve; one outlet of the bi-stable electromagnetic valve is connected with a rapid-freezing capillary tube and a rapid-freezing evaporator in turn and the other outlet of the bi-stable electromagnetic valve is connected with a wide temperate zone capillary tube and a wide temperate zone evaporator in turn; the rapid-freezing evaporator and the wide temperate zone evaporator are connected with a freezing evaporator after being in parallel connection with each other; the refrigeration evaporator and the freezing evaporator are connected with the compressor after being in parallel connection with each other. The invention also discloses the refrigerator with the three-door multi-temperature-zone refrigeration system and the control method thereof. The refrigerator is a multi-temperature-zone refrigerator with the rapid-freezing function and accordingly the relative independence of chambers is implemented, the requirements of the different chambers for the refrigerating capacity can be met, and the problems that the irreversible loss of the refrigeration chamber is large and the start-stop of the compressor is frequent, and the like are solved.
