AI Technical Summary

Technical Problem

Existing multi-door refrigerators have long operating times and their lifespan and performance are affected because the refrigeration system needs to cool multiple compartments at the same time. At the same time, the air duct design of the refrigerator compartment affects the volume utilization rate.

Method used

It adopts independent refrigeration systems for the refrigerator compartment and the freezer/variable temperature/zero degree compartment, while sharing the freezer compartment refrigeration system. The air duct of the refrigerator compartment is changed to the air duct of the freezer compartment to provide air supply, and the design of the air door for the variable temperature compartment and the zero degree compartment is eliminated, simplifying the structure of the refrigerator air duct.

Benefits of technology

It reduces the operating time of the refrigeration system in the cold storage compartment, improves the volume utilization rate of the cold storage compartment, achieves faster and more uniform cooling of the variable temperature compartment and the zero-degree compartment, and reduces energy consumption.
