Description
Technical Field
The invention belongs to the technical field of refrigerators, and particularly relates to a refrigerator refrigeration control method and a refrigerator refrigeration control device.
Background
With the improvement of living standard, the multi-temperature zone and large-volume refrigerator gradually becomes the mainstream of the market. This type of refrigerator is usually designed with a multi-cycle refrigeration system, which offers many advantages: the temperature of each compartment is independently controlled, the food storage is not tainted with the smell, a wide temperature-changing area can be designed, the electricity and the energy are saved, and the like. However, this also brings about a significant disadvantage: the refrigeration of multiple circulation systems interfere with each other, and the refrigeration of one compartment may cause the temperature of another compartment to be affected, even the temperature drifts, and affect the use of users, for the following reasons:
the multi-cycle refrigeration system is provided with a plurality of evaporators which are arranged in parallel or in series, the inlet end of each evaporator is connected with a corresponding capillary tube (throttling component), and the on-off of each capillary tube is controlled through an electric valve or an electromagnetic valve and the like, so that the refrigeration control of the evaporators and the corresponding chambers is realized. In order to stabilize the operation condition of the refrigeration system, the refrigeration cycle is usually designed such that only one capillary tube is in a passage and only one evaporator is in a refrigeration state in the same time period. In order to deal with the situation that a plurality of compartments have refrigeration demands at the same time, each compartment of the refrigerator is designed with a high-priority refrigeration time sequence, a middle-priority refrigeration time sequence and a low-priority refrigeration time sequence, under the situation that the plurality of compartments have refrigeration demands at the same time, the compartment with the high priority level has a priority refrigeration authority, and the compartment with the low priority level has the refrigeration authority after the high-priority compartment reaches a stop point. The mode of 'queuing' sequential refrigeration control can lead to slow and lagging refrigeration of the low-priority compartment, and when the high-level compartment has a large refrigeration load and needs refrigeration for a long time, the low-level compartment can be always in a waiting state, thus leading to obvious temperature return and influencing the use experience of users.
In order to solve the problem of slow and lagging refrigeration of the low-priority compartment of the multi-cycle refrigeration system refrigerator, the invention provides a refrigeration control method and a control device of the refrigerator. Therefore, the problem of lagging cooling speed of the low-priority compartment is solved, and the using experience satisfaction of a user is improved.
