Details of the Innovation Need

I. Background:

The current resistance heating wire defrosting in refrigerator products poses the following problems:

1. The taste and quality of long-term storage of frozen meat is poor. Shrimp head becomes black, dumpling skin crack and other phenomenon ;( high temperature fluctuation, repeated when freezing and thawing cycles)

2. High energy consumption of refrigerator: the efficiency of the heating wire conduction defrosting is low (=90%

3. The maximum temperature difference of the evaporator as a whole
