Examples
The refrigerator is provided with a plurality of refrigeration gears in an energy-saving refrigeration mode, each refrigeration gear corresponds to a preset mass Mn, n is the number of the refrigeration gears, and n is an integer larger than 2. The preset quality corresponding to each refrigeration gear is different. The Mn can be measured by a laboratory in advance to determine the weight of some food materials and the time for maintaining a certain temperature, and a database is formed. Then, the refrigeration system is divided into different gears (facing to the main food material types, weight or quantity of users, time expected to be maintained and other parameters, and the gears are integrated into a first refrigeration gear, a second refrigeration gear and a third refrigeration gear \8230;).
When the refrigerator is in the energy-saving refrigeration mode, one refrigeration gear is selected for refrigeration, when the refrigerator needs to be supplemented with coolant in the energy-saving refrigeration mode, it is judged that the refrigeration gear at the time cannot meet the refrigeration requirement of the refrigerator, and in order to ensure the normal work of the refrigerator, the refrigerator does not adjust the refrigeration gear in the energy-saving refrigeration mode at the time. But after the refrigerator exits the energy-saving refrigeration mode, the refrigeration gear is adjusted, so that the numerical value of the preset mass is increased, and the mass of the coolant in the cold storage chamber 11 is correspondingly increased.
When the refrigerator is switched to the energy-saving refrigeration mode next time, the refrigerator operates according to the refrigeration gear adjusted last time, and whether the condition that the coolant needs to be supplemented exists in the energy-saving refrigeration mode of the refrigerator is judged again.
Taking the refrigerator with three refrigeration gears as an example for explanation,
the three refrigeration gears comprise a first refrigeration gear, a second refrigeration gear and a third refrigeration gear, the preset mass corresponding to the first refrigeration gear is M1, the preset mass corresponding to the second refrigeration gear is M2, the preset mass corresponding to the third refrigeration gear is M3, and M3 is greater than M2 and greater than M1;
when the refrigerator is in an energy-saving refrigeration mode, when the refrigerator operates at a first refrigeration gear, the actual mass M of the coolant in the cold storage chamber 11 is compared with M1, if M is less than or equal to aM1, it is judged that M1 in the first refrigeration gear cannot meet the refrigeration requirement of the refrigerator, and after the refrigerator completes the operation at the first refrigeration gear, the refrigeration gear is adjusted to a second refrigeration gear;
when the refrigerator is switched to the energy-saving refrigeration mode next time, the refrigerator operates in the adjusted second refrigeration gear, the actual mass M of the coolant in the cold storage chamber 11 is compared with M2, and then whether the condition that M is less than or equal to aM2 occurs is judged again;
if so, adjusting the refrigeration gear to a third refrigeration gear;
if the second refrigeration gear does not exist, the second refrigeration gear is proved to meet the refrigeration requirement of the refrigerator, and the second refrigeration gear is kept unchanged.
