Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to a refrigerator energy-saving control method and device, a storage medium and an electronic device. BACKGROUND

[0002] In related technologies, the refrigeration mode of a single-system freezing and refrigerating box is mostly to deliver the cold air generated in the freezing chamber to other compartments through the air duct foamed in the box. When the temperature of a compartment reaches the start temperature under the corresponding working condition, the single-system freezing and refrigerating box controls the compressor and air door to carry out the refrigeration process of the compartment. When the temperature of the compartment reaches the stop temperature under the corresponding working condition, the compartment controls the compressor and air door to end the refrigeration process of the compartment. Because the heat loads of the compartments of the freezing and refrigerating box are different, the start and stop points of the compartments may not coincide, which causes the compressor to frequently start and stop to meet the refrigeration requirements of the compartments. The work done by the compressor to break the balance of the refrigeration system at the start moment is much higher than that in the normal operation stage, which increases the energy consumption and causes energy waste.

[0003] For the above problems in related technologies, no efficient and accurate solution has been found. SUMMARY

[0043] Optionally, the target compartment with independent start and stop of the compressor is the compartment with the starting refrigeration time point and the stopping refrigeration time point both in front.

[0044] In the embodiment, the inter-room types are classified by the heat load level, and can be classified into high-load inter-rooms and low-load inter-rooms. The determination of the inter-room type of the target inter-room includes: in a single refrigeration cycle, if the first start refrigeration time point and the first stop refrigeration time point of the high-load inter-room are both before the second start refrigeration time point of the low-load inter-room, the inter-room type of the target inter-room is determined as the high-load inter-room, wherein the high-load inter-room is an inter-room with a heat load greater than a first preset value; in a single refrigeration cycle, if the second start refrigeration time point and the second stop refrigeration time point of the low-load inter-room are both before the first start refrigeration time point of the high-load inter-room, the inter-room type of the target inter-room is determined as the low-load inter-room, wherein the low-load inter-room is an inter-room with a heat load less than a second preset value.

[0072] S33, judging the starting and stopping condition;

[0073] Optionally, by comparing the order of the starting cooling time point and the stopping cooling time point of the high-load inter-room and the low-load inter-room, it can be determined whether there is a single inter-room independent start-stop condition within a single compressor start-stop time. The determination method is that, within a single start-stop cycle of the compressor, if the starting cooling time point and the stopping cooling time point of at least one inter-room are both before the starting cooling time point of another inter-room, then there is a target inter-room of the compressor independent start-stop. If there is a single inter-room independent start-stop condition within a single compressor start-stop time, then it is determined whether the independent start-stop inter-room is a low-load inter-room independent start-stop or a high-load inter-room independent start-stop. The determination method is that, within a single refrigeration cycle, if the first starting cooling time point and the first stopping cooling time point of the high-load inter-room are both before the second starting cooling time point of the low-load inter-room, then it is determined that the inter-room type of the target inter-room is a high-load inter-room, wherein the high-load inter-room is an inter-room with a heat load greater than a first preset value. Within a single refrigeration cycle, if the second starting cooling time point and the second stopping cooling time point of the low-load inter-room are both before the first starting cooling time point of the high-load inter-room, then it is determined that the inter-room type of the target inter-room is a low-load inter-room, wherein the low-load inter-room is an inter-room with a heat load less than a second preset value.

[0074] S34, if the low-load inter-room is independently started and stopped; the low-load inter-room is cooled at Thoff+0.5m℃; the low-load inter-room is stopped cooling at Tloff-0.5n℃; it is determined whether the high-load inter-room stop time / low-load inter-room stop time is less than 2; if T(true), n=n+1 (n≤4); the program jumps to continue execution at Tloff-0.5n℃ for stopping cooling of the low-load inter-room; if F(false), m=m+1 (m≤4); the program jumps to continue execution at Thoff+0.5m℃ for cooling of the low-load inter-room;

[0075] Optionally, if the low-load chamber is independently opened and stopped, the low-load chamber is cooled when the high-load chamber temperature reaches Thoff+0.5m℃ (Thoff represents the high-load chamber stop temperature, m is a positive integer and m∈[1, 4]), that is, Tlon=Thoff+0.5m℃ (Tlon represents the low-load chamber start cooling temperature); the cooling process of the low-load chamber is ended when the low-load chamber temperature reaches Tloff-0.5n℃ (Tloff represents the low-load chamber stop temperature, n is an integer and n∈[0, 4]), that is, Tloff=Tloff-0.5n℃. At this time, the high-load chamber stop time length and the low-load chamber stop time length are calculated, which refers to the non-cooling time length of the chamber, that is, the time length from the end of the cooling process to the start of the cooling process again. Different from the compressor stop time, there is a situation that a chamber is in the stop time period, but the compressor is still running; if the ratio of the high-load chamber stop time / low-load chamber stop time is less than 2, the value of n in Tloff=Tloff-0.5n℃ is adjusted to n+1; if the ratio of the high-load chamber stop time / low-load chamber stop time is greater than or equal to 2, the value of m in Tlon=Thoff+0.5m℃ is adjusted to m+1.

[0076] S35, if the high-load chamber is independently opened and stopped; the low-load chamber is cooled at Thoff+0.5m℃; the low-load chamber is stopped cooling at Tloff-0.5n℃; it is judged whether the low-load chamber is independently opened and stopped; if it is F (false), it is continued to be executed by jumping to the low-load chamber cooling at Thoff+0.5m℃; if it is T (true), n=n+1 (n≤4), it is continued to be judged whether the low-load chamber is independently opened and stopped; if it is F (false), it is continued to be executed by jumping to the low-load chamber cooling at Thoff+0.5m℃; if it is T (true), m=m+1 (m≤4), the program is continued to be executed by jumping to the low-load chamber cooling at Thoff+0.5m℃.

[0077] Optionally, if high-load chamber independent start-stop occurs, the low-load chamber is started to be refrigerated when the high-load chamber temperature reaches Thoff+0.5m℃ (Thoff represents the high-load chamber stop temperature, m is a positive integer and m∈[1, 4]), that is, Tlon=Thoff+0.5m℃ (Tlon represents the low-load chamber start refrigeration temperature); the low-load chamber refrigeration process is ended when the low-load chamber temperature reaches Tloff-0.5n℃ (Tloff represents the low-load chamber stop temperature, n is an integer and ∈[0, 4]), that is, Tloff=Tloff-0.5n℃. If the low-load chamber independent start-stop occurs at this time, the value of n in Tloff=Tloff-0.5n℃ is adjusted to n+1; if the low-load chamber independent start-stop still occurs, the value of m in Tlon=Thoff+0.5m℃ is adjusted to m+1.

[0078] The present application collects the time points of refrigeration start and stop of each chamber of the single-system refrigeration and freezing box, counts the refrigeration time and time interval of each chamber, compares the sequence of each time point, determines whether the chamber independent refrigeration occurs and determines the chamber type of independent refrigeration, and after determining the chamber type, adjusts the temperature points of the chambers to reduce the start-stop times as much as possible under the premise of meeting the chamber temperature, so as to achieve the purpose of reducing energy consumption.
