Abstract

The invention discloses a single-system three-temperature-controlled refrigerating refrigerator and a refrigerating control method thereof. The single-system three-temperature-controlled refrigeratingrefrigerator comprises a refrigerating inner container, a freezing inner container, a variable-temperature inner container and a refrigerating system, wherein a variable-temperature air door is arranged in the refrigerating inner container; and a heating element is arranged at a refrigerating air-feeding tube. The refrigerating control method comprises a cold-storage refrigerating mode RS, a variable-temperature refrigerating mode F2 and a freezing refrigerating mode FS, wherein the variable-temperature refrigerating mode comprises the following steps: BS1: starting a variable-temperature fanif a variable-temperature inner container temperature TV is higher than a variable-temperature inner container start-up point; BS2: starting a compressor if a variable-temperature set temperature islower than (-)13 DEG C or an evaporator temperature TE is higher than a freezing start-up point, namely (-)2 DEG C, and a freezing temperature is higher than a freezing start-up point, namely (-)0.5 DEG C; and BS3: shutting off the variable-temperature fan if the variable-temperature temperature is lower than a variable-temperature stop point, and entering the RS4 process.

Description

technical field

[0001] The invention relates to a refrigerator and a refrigeration control method thereof, in particular to a single-system three-temperature-control refrigeration refrigerator and a refrigeration control method thereof. Background technique

[0002] At present, the existing three-door refrigerator has three chambers, including refrigeration, variable temperature, and freezing. The implementation of the three-door refrigerator mainly has two circulation systems for temperature control and three circulation systems for temperature control. It is rare to use a single refrigeration system to control the temperature in the refrigerated liner, variable temperature liner and freezer liner.

[0003] In addition, in the existing variable temperature control system, the temperature change function from refrigeration to soft freezing to freezing cannot be realized. It can only be adjusted between refrigeration and soft freezing. The lowest temperature is around -7°C, a...
