The invention discloses a refrigerator refrigeration defrosting system and a refrigerator, and relates to the technical field of refrigeration. Comprising a compressor, evaporators, a condenser, a filter, an air return pipe and an electromagnetic valve, the evaporators comprise the first evaporator and the second evaporator, and the evaporators are mutually connected to form three refrigerating and defrosting modes. The refrigerating and defrosting modes comprise a first mode, a second mode and a third mode, the first mode corresponds to the normal refrigerating stage of the first evaporator and the second evaporator, and the second mode corresponds to the defrosting stage of the first evaporator and the refrigerating stage of the second evaporator; the third mode corresponds to the defrosting stage of the second evaporator and the refrigerating stage of the first evaporator, and the first mode, the second mode and the third mode can be switched through the electromagnetic valve. When heating and defrosting a
