Embodiment 1
[0026] Such as figure 1 Shown is the schematic diagram of the temperature control of the refrigerator in embodiment 1, figure 1 The middle abscissa is the time axis, and the ordinate of the upper curve is the temperature, which shows the temperature change of the refrigerator with time, which is used to illustrate the temperature control of the refrigerator. The lower curve shows the compressor of the refrigerator corresponding to the temperature change. In the case of opening and closing, the upper part of the lower curve indicates that the compressor of the refrigerator is turned on, and the lower part indicates that the compressor of the refrigerator is turned off. The same part of the refrigerator of this embodiment as the refrigerator of conventional design in the field is: it includes a compressor, and the corresponding operating frequency when the refrigeration efficiency of the compressor is the highest is the optimal operating frequency, and the refrigerator is provid...
Embodiment 2
[0031] On the basis of Example 1, the first temperature difference 1 is 2.5-3.5 degrees Celsius. More specifically, the first temperature difference 1 may be 3 degrees Celsius. Such as figure 2 As shown, the refrigerator in this embodiment is provided with a second temperature difference 4, a second upper limit temperature and a second lower limit temperature to replace the first temperature difference 1, the first upper limit temperature and the first lower limit temperature 2 respectively during the low electricity price time period. , wherein the second temperature difference 4 is smaller than the first temperature difference 1, the difference between the second upper limit temperature and the second lower limit temperature is the second temperature difference 4, and the average value of the second upper limit temperature and the second lower limit temperature is the The first reference temperature 5.
[0032] In this way, while the first reference temperature 5 remains ...
Embodiment 3
[0034] On the basis of Embodiment 1 or Embodiment 2, the refrigerator can be set with a third temperature difference 6, a third upper limit temperature and a third lower limit temperature to replace the first temperature difference 1, the first upper limit temperature and the third lower limit temperature respectively during the period of high electricity price. The first lower limit temperature 2, wherein the third temperature difference 6 is greater than the first temperature difference 1, the difference between the third upper limit temperature and the third lower limit temperature is the third temperature difference 6, the third upper limit temperature and the third lower limit temperature The average value of is the first reference temperature 5. Such as figure 2 A time point 8 shown separates the time period of high electricity price and the time period of low electricity price, wherein the time point 8 is preceded by the time period of high electricity price. Similarl...
