On the one hand interior contact is contacted with compartment external environment, the temperature difference difference of the two is very big, such as temperature internal for freezing chamber
Degree at -18 DEG C hereinafter, and ambient temperature sometimes at 20 DEG C or more, therefore so big temperature difference leads to these positions of central sill 70
It is easy to produce condensed water.Reality, since the temperature inside freezing chamber is minimum, is set to freezing chamber for refrigerator complete machine
The condensed water that the surface of 70 part of central sill generates generates most.To prevent central sill 70 from generating condensed water, it is arranged inside central sill 70
Anti-condensation pipe, anti-condensation pipe when compressor 30 is run heating to play the role of preventing water condensation.Anti-condensation pipe is substantially
A part of condenser in the refrigeration system of refrigerator, according to the refrigeration principle of refrigerator it is found that when compressor 30 is run, pipeline

The example of relationship between border temperature and compressor gear.
Table 1
| Environment temperature | ≤15℃ | 15~30 DEG C | ≥30℃ |
| Corresponding compressor gear | R2 | R3 | R4 |
Each gear can correspond to different revolving speeds.Table 2 shows the exemplary relationship between compressor gear and revolving speed.
Table 2
| Compressor gear Ri | R1 | R2 | R3 | R4 |
| Corresponding revolving speed RPM | 1200 | 1800 | 2400 | 3600 |
For example, determining that the gear of compressor operation is R2 i.e. 2400RPM when current environmental temperature is 25 DEG C, reducing by one grade
Then become R2 i.e. 1800RPM.
After reducing by one grade with this, the revolving speed of compressor is reduced, again such that the temperature of central sill 70 increases, promotes anti-condensation effect
