Embodiment Construction

[0019] Such as figure 1 As shown, the method for calculating the dynamic frosting time proposed by the present invention includes: collecting the operating parameters and usage data of the refrigerator, and calculating the preset frosting time t according to the collection results 预 Make real-time corrections to get the next frosting time t n+1 .

[0020] At the initial stage of power-on of the refrigerator, the next frosting time is t n+1 It is the interval time between the power-on time of the refrigerator and the start time of the first defrosting, and the actual interval time t starts counting when the refrigerator is powered on 实际 , and calculate the next frosting time t n+1 , when the actual interval reaches the next frosting time t n+1 when t 实际 =t n+1 , the refrigerator will defrost for the first time. During the entire use of the refrigerator after the initial defrosting, the next frosting time t n+1 is the interval between the exit time of this defrost and th...

Abstract

The invention discloses a dynamic frosting time calculation method and a refrigerator. The dynamic frosting time calculation method includes: collecting operating parameters and usage data of the refrigerator, and calculating the preset frosting time t according to the collection results 预 Make real-time corrections to get the next frosting time t n+1 , t n+1 =(A+B+C)t 预 +(T n -T n‑1 ) E / 60, A is the environmental coefficient, B is the door opening coefficient, C is the compressor coefficient, T n is the defrosting time, T n‑1 is the last defrosting time and E is the defrosting influence coefficient. The frosting time calculated by the present invention is more accurate, and the refrigerator defrosts at an appropriate time without frequent defrosting, which is more energy-saving and environmentally friendly. At the same time, it can avoid the problem of long defrosting intervals. The fluctuation is small, and the preservation effect of the refrigerator is good.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a dynamic frosting time calculation method and a refrigerator. Background technique [0002] With the improvement of people's quality of life, the requirements for the preservation effect of refrigerators are getting higher and higher. Air-cooled refrigerators are flocked to the market because of their advantages of fast cooling speed and good insurance effect. At present, the market share of air-cooled refrigerators exceeds 80%. , but air-cooled refrigerators have not existed in the Chinese market for a long time, and there have been many problems since they were launched. The most important problem is that defrosting is not timely. [0003] Most of the air-cooled refrigerators in the prior art use methods such as timing defrosting and opening the door to reduce the frosting cycle to solve the defrosting problem. The frosting time is fixed, and the refrigerator def...
