Description

Technical Field

[0001] This invention belongs to the field of refrigeration, and more specifically, relates to a refrigerator. This invention also relates to the control logic of the refrigerator and a computer-readable storage medium. Background Technology

[0002] Refrigerated boxes belong to the refrigeration field. They mainly consist of a heat-insulated box, a refrigeration unit, and a fan. During use, the refrigeration unit, driven by an external power source, cools the inside of the heat-insulated box to maintain a certain temperature, thus facilitating the cold chain transportation or storage of items inside.

[0003] Existing evaporator technologies are mostly limited to improving the evaporator's cooling effect and cooling rate. After the refrigeration unit stops, the insulation performance of the box itself is used to slow down the temperature rise inside the box. Furthermore, due to the varying heat loads of transported goods, the unit's cooling capacity tends to be relatively high when transporting goods with different heat loads. This can easily lead to over-cooling during use, causing the temperature inside the refrigerated box to drop below the preset temperature within a short period. Additionally, while existing refrigeration boxes have high refrigeration redundancy, they also tend to waste refrigeration power. Moreover, some inverter refrigerated boxes, due to unreasonable control logic design, exhibit sawtooth or abrupt temperature fluctuations during operation, which is unfavorable for storing temperature-sensitive items. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator to improve the problem of energy waste caused by excessive refrigeration power consumption in existing refrigerators.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a refrigerator box, comprising a box body, a cold storage evaporator and a refrigeration unit, wherein the cold storage evaporator comprises a cold storage block for collecting excess refrigeration capacity of the refrigeration unit and an evaporator body disposed on the cold storage block;

[0006] The evaporator body includes multiple evaporation units arranged in rows, with air-cooled channels formed between two adjacent evaporation units. Each evaporation unit includes a heat-conducting plate, a refrigeration pipe, and a phase change tube. The refrigeration pipe and the phase change tube are arranged at intervals and alternately connected to the heat-conducting plate along a preset path. The central axes of the refrigeration pipe and the phase change tube are parallel to the surface of the heat-conducting plate.

[0007] In one possible implementation, the phase change tubes in the plurality of evaporation units are connected in series, and the refrigeration tubes in the plurality of evaporation units are connected in series.

[0008] In one possible implementation, in any of the evaporation units, the heat-conducting plate has a serrated cross-section, and a channel is provided in the heat-conducting plate for accommodating the refrigeration pipe or the phase change tube, and the channel is located at the serrated tip of the heat-conducting plate.

[0009] In one possible implementation, multiple low-pressure recesses are formed at intervals on the surface of the heat-conducting plate along the length of the air-cooling channel. The refrigeration pipe and the phase change pipe are both disposed in the low-pressure recesses and are connected to the heat-conducting plate through connectors. The connectors are integrally formed with the heat-conducting plate, and the cross-sections of the refrigeration pipe and the phase change pipe are both elongated streamlined shapes.

[0010] In one possible implementation, the evaporator further includes a fixing plate for fixing each group of evaporation units, and the surface of the fixing plate is perpendicular to the surface of the heat-conducting plate. A through hole is provided on the fixing plate for the refrigeration pipe and the phase change pipe to pass through, and the through hole is parallel to the thickness direction of the fixing plate.

[0011] In one possible implementation, wavy protrusions are formed on both sides of the heat-conducting plate. On the surface of any one of the heat-conducting plates, a low-pressure depression is formed between two adjacent wavy protrusions. Furthermore, on the surfaces of two adjacent heat-conducting plates, the tip of the protrusion on one heat-conducting plate corresponds to the waist of the protrusion on the other heat-conducting plate. The beneficial effects of the refrigerator provided by this invention are as follows: Compared with the prior art, the refrigerator of this invention, by setting a cold storage evaporator, can store a portion of the cold energy when the refrigeration power of the refrigeration unit inside the refrigerator is too high, thereby facilitating temperature maintenance inside the refrigerator and reducing temperature fluctuations. In addition, when the refrigeration unit needs to perform refrigeration operations inside the refrigerator, the release of cold energy through the cold storage evaporator can reduce the power consumption of the refrigeration unit and slow down the temperature rise inside the refrigerator.

[0012] Furthermore, by incorporating a heat-conducting plate that connects the refrigeration pipe and the phase change tube, this invention accelerates the cooling efficiency of the phase change tube, thereby enhancing the efficiency of the cold storage block in collecting redundant cooling capacity from the refrigeration unit. Simultaneously, since the central axes of both the refrigeration pipe and the phase change tube are perpendicular to the thickness direction of the heat-conducting plate, it facilitates airflow through the air-cooled channel, thereby enhancing the heat exchange efficiency between the evaporator and other structures of the refrigerator.

[0013] Another object of the present invention is to provide a control logic for a refrigerator, the control logic of which has the refrigerator as described above, and the control logic of the refrigerator includes the following steps:

[0014] S100: Sequentially acquire the preset cooling power consumption of the refrigerator within multiple unit time periods;

[0015] S200. Obtain the first actual cooling power consumption, calculate the difference between the first actual cooling power consumption and the first preset cooling power consumption, correct the cooling power of the refrigeration unit based on the difference, correct the cooling power of the cold storage evaporator based on the difference, and correct the cold storage power of the cold storage evaporator based on the difference.

[0016] S300. Based on the difference between the initial actual cooling power consumption and the initial preset cooling power consumption, determine a first correction coefficient Δ, and adjust the initial cooling power of the refrigeration unit and the initial cooling or initial cold storage power of the cold storage evaporator according to the first correction coefficient Δ.

[0017] If the actual cooling power consumption of the second position is greater than that of the first position, then the first correction coefficient 1≤Δ≤1.2, and the greater the difference between any two adjacent actual cooling power consumptions, the closer the first correction coefficient Δ is to 1.

[0018] If the actual cooling power consumption of the second position is equal to the actual cooling power consumption of the first position, then the first correction coefficient Δ = 1;

[0019] If the actual cooling power consumption of the second position is less than the actual cooling power consumption of the first position, then the first correction coefficient 0.8 ≤ Δ ≤ 1.

[0020] In one possible implementation, the refrigeration unit includes two independently operating compressors, and if the first correction coefficient Δ > 1, then at least one of the two compressors is turned on.

[0021] In one possible implementation, if the first correction coefficient is greater than or equal to 1, the cold storage evaporator performs refrigeration; if the first correction coefficient is less than or equal to 1, the cold storage evaporator stores cold.

[0022] Another object of the present invention is to provide a computer-readable medium storing instructions that, when run on a computer, enable the computer to execute the control logic of the refrigerator as described above. Attached Figure Description

[0037] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0038] Please refer to the following: Figure 1 and Figure 2 The refrigerator box provided by the present invention will now be described. The refrigerator box includes...

[0039] A refrigerator includes a cabinet 1, a cold storage evaporator 2 and a refrigeration unit 3, wherein the cold storage evaporator 2 includes a cold storage block 21 for collecting excess cooling capacity of the refrigeration unit 3 and an evaporator body 22 disposed on the cold storage block 21.

[0040] The evaporator body 22 includes multiple evaporation units 221 arranged in rows. A cooling channel 222 is formed between two adjacent evaporation units 221. Each evaporation unit 221 includes a heat-conducting plate 2211, a refrigeration pipe 2212 and a phase change tube 2213. The refrigeration pipe 2212 and the phase change tube 2213 are arranged at intervals and alternately connected to the heat-conducting plate 2211 along a preset path. The central axis of the refrigeration pipe 2212 and the phase change tube 2213 are parallel to the surface of the heat-conducting plate 2211.

[0041] In this embodiment, the preset path can be set to be straight, wavy, or serrated. Accordingly, the heat-conducting plate 2211, cooling pipe 2212, and phase change tube 2213 arranged according to different preset paths can form air-cooling channels 222 of corresponding shapes.

[0042] The beneficial effects of the refrigerator provided by the present invention are as follows: Compared with the prior art, the refrigerator of the present invention, by setting up a cold storage evaporator 2, can store a portion of the cold energy when the refrigeration power of the refrigeration unit 3 in the refrigerator is too high, so as to help maintain the temperature in the refrigerator and reduce the temperature fluctuation in the refrigerator; in addition, when the refrigeration unit 3 needs to perform refrigeration operation in the refrigerator, the release of cold energy by the cold storage evaporator 2 can reduce the power consumption of the refrigeration unit 3 and slow down the rising trend of the temperature in the refrigerator.

[0043] Furthermore, by providing a heat-conducting plate 2211 that connects the refrigeration pipe 2212 and the phase change tube 2213, the present invention can accelerate the cooling efficiency of the phase change tube 2213, thereby enhancing the efficiency of the cold storage block 21 in collecting redundant cooling capacity of the refrigeration unit 3. Simultaneously, since the central axes of both the refrigeration pipe 2212 and the phase change tube 2213 are perpendicular to the thickness direction of the heat-conducting plate 2211, airflow through the air-cooling channel 222 is facilitated, enhancing the heat exchange efficiency of the evaporator body 22.

[0044] Regarding the positional relationship between the evaporator body 22 and the cold storage block 21, preferably, in the refrigerator, the cold storage block 21 is located at the bottom of the box 1 and is close to the refrigeration unit 3; while the evaporator body 22 is located above the cold storage block 21 and is also close to the refrigeration unit 3, so as to save the connecting pipeline between the cold storage evaporator 2 and the refrigeration unit 3.

[0045] In some embodiments, please refer to Figures 3 to 6In each evaporation unit 221, the length direction of the refrigeration pipe 2212 and the length direction of the phase change pipe 2213 are parallel to each other, and the multiple heat-conducting plates 2211 used to connect the refrigeration pipe 2212 and the phase change pipe 2213 are arranged in a wave-like manner to increase the heat exchange area between the heat-conducting plates 2211 and the airflow.

[0046] In addition, please see Figure 3 To facilitate the connection of phase change tubes 2213 and refrigeration tubes 2212 in different evaporation units 221, the phase change tubes 2213 in multiple evaporation units 221 are connected in series, and the refrigeration tubes 2212 in multiple evaporation units 221 are connected in series. For each refrigeration tube 2212, a refrigeration liquid collection pipe 2214 communicating with each refrigeration tube 2212 is provided in the evaporator body 22; similarly, for each phase change tube 2213, a phase change material liquid collection pipe 2215 communicating with each phase change tube 2213 is provided in the evaporator body 22.

[0047] In some embodiments, please refer to Figure 1 and Figure 2 The refrigeration unit 3 is located on the side wall of the refrigerator box 1. The cold storage evaporator 2 is close to the refrigeration unit 3 to save on the connecting pipeline between the refrigeration unit 3 and the cold storage evaporator 2. More specifically, the refrigeration unit 3 includes a condenser 32, a compressor 31 and an oil tank 33. The compressor 31 is driven by gasoline and cools the inside of the box 1 through the condenser 32.

[0048] In some embodiments, please refer to Figure 6 and Figure 9 In order to increase the heat exchange area between the heat-conducting plate 2211 and the airflow, in any evaporation unit 221, the cross-section of the heat-conducting plate 2211 is serrated, and a channel 2217 for accommodating the refrigeration pipe 2212 or the phase change pipe 2213 is provided in the heat-conducting plate 2211. The channel 2217 is located at the tip of the tooth of the heat-conducting plate 2211.

[0049] In this embodiment, by placing the channel 2217 at the tip of the tooth of the heat-conducting plate 2211, it is more conducive to the airflow in the air-cooling channel to carry away the heat on the cooling pipe 2212 and the phase change pipe 2213.

[0050] It should be noted that you should refer to [link / reference]. Figure 9 At the ends of two adjacent heat-conducting plates 2211 in an evaporation unit 221, there are arc-shaped protrusions. Two adjacent arc-shaped protrusions in the same unit together form a channel 2217.

[0051] In some embodiments, please refer to Figure 7In order to increase the airflow velocity through the air-cooling channel 222, multiple low-pressure recesses 223 are formed at intervals on the surface of the heat-conducting plate 2211 along the length of the air-cooling channel 222. The refrigeration pipe 2212 and the phase change pipe 2213 are both located in the low-pressure recesses 223 and are connected to the heat-conducting plate 2211 through the connector 225. The connector and the heat-conducting plate 2211 are integrally formed, and the cross-sections of the refrigeration pipe 2212 and the phase change pipe 2213 are both elongated streamlined shapes.

[0052] In this embodiment, during the flow of air in the air-cooled channel 222, after passing through the streamlined refrigeration pipe 2212 and the phase change pipe 2213, the airflow will be split from the air-cooled channel 222 and the low-pressure recess 223. The split airflow branch is accelerated and merges into the air-cooled channel 222 as it flows through the low-pressure recess 223. This accelerates the airflow in the air-cooled channel 222 and increases the heat exchange area between the heat-conducting plate 2211 and the airflow, thereby enhancing the heat exchange rate of the evaporator body 22.

[0053] In some embodiments, please refer to Figure 3 The evaporator body 22 also includes a fixing plate 224 for fixing each group of evaporation units 221, and the plate surface of the fixing plate 224 is perpendicular to the plate surface of the heat conduction plate 2211. A through hole is provided on the fixing plate 224 for the refrigeration pipe 2212 and the phase change pipe 2213 to pass through, and the depth direction of the through hole is parallel to the thickness direction of the fixing plate 224.

[0054] In some embodiments, please refer to Figure 7 Both sides of the heat-conducting plate 2211 are formed with wavy protrusions 2216. On the surface of any heat-conducting plate 2211, a low-pressure depression 223 is formed between two adjacent wavy protrusions 2216. On the surface of two adjacent heat-conducting plates 2211, the tip of the protrusion of any heat-conducting plate 2211 corresponds to the waist of the protrusion of the other heat-conducting plate 2211.

[0055] In this embodiment, by utilizing the staggered serrated protrusions, the airflow can make fuller use of the low-pressure effect and narrow tube effect brought by the serrated protrusions to increase the flow velocity as it flows through the air-cooling channel 222. At the same time, the staggered serrated protrusions can also reduce the overall thickness of the heat-conducting plate 2211, thereby increasing the surface area ratio of the heat-conducting plate 2211 and thus enhancing the heat exchange effect of the heat-conducting plate 2211.

[0056] Among existing refrigerators, inverter refrigerators account for the majority. However, due to the insufficient temperature uniformity during the frequency conversion adjustment process, existing inverter refrigerators have an adverse effect on the preservation of items inside the refrigerator (especially items that are more sensitive to temperature changes).

[0057] To address the aforementioned problems, another objective of this invention is to propose a control logic for a refrigerator to improve the uniformity of temperature inside the refrigerator. The control logic in this solution is based on the aforementioned refrigerator implementation, such as... Figure 8 As shown, the control logic of the refrigerator includes the following steps:

[0058] S100: Sequentially obtain the preset cooling power consumption of the refrigerator within multiple unit time periods;

[0059] S200. Obtain the initial actual cooling power consumption, calculate the difference between the initial actual cooling power consumption and the initial preset cooling power consumption, correct the cooling power of the refrigeration unit 3 based on the difference, correct the cooling power of the cold storage evaporator 2 based on the difference, and correct the cold storage power of the cold storage evaporator 2 based on the difference, so as to obtain the corrected initial cooling power.

[0060] S300. Based on the difference between the initial actual cooling power consumption and the initial preset cooling power consumption, determine the first correction coefficient Δ, and adjust the initial cooling power of the refrigeration unit 3 and the initial cooling power or initial cold storage power of the cold storage evaporator 2 according to the first correction coefficient Δ.

[0061] S400. If the second-order actual cooling power consumption is greater than the first-order actual cooling power consumption, then the first correction coefficient 1≤Δ≤1.2, and the greater the difference between two adjacent actual cooling power consumptions, the closer the first correction coefficient Δ is to 1; if the second-order actual cooling power consumption is equal to the first-order actual cooling power consumption, then the first correction coefficient Δ=1; if the second-order actual cooling power consumption is less than the first-order actual cooling power consumption, then the first correction coefficient 0.8≤Δ≤1.

[0062] Compared with the prior art, the present invention can shorten the adjustment time required to correct the first actual cooling power consumption by setting the control logic of the refrigerator, thereby improving the overall cooling efficiency of the refrigerator and reducing the cooling redundancy of the refrigeration unit 3.

[0063] More specifically, the actual application process of this embodiment is described below:

[0064] In steps S100 to S400, the preset cooling power consumption is estimated based on the material, volume, and temperature of the items to be contained in the refrigerator, and the initial temperature inside the refrigerator is memorized. Therefore, it has a certain deviation.

[0065] Taking vegetables as an example, their specific heat capacity is relatively large. During the process of vegetables cooling from room temperature to storage temperature (4°C) within two hours, due to the heat release process of the vegetables and the cooling mechanism of the refrigeration unit 3, the existing refrigeration unit 3's cooling process inside the refrigerator is stepwise. In this application, by obtaining the difference between the actual cooling power consumption in the first stage (approximately 1-2 minutes) and the preset cooling power consumption (i.e., the power consumption required for the refrigerator to lower the internal temperature to the preset temperature per unit time during the actual cooling process), a first correction coefficient Δ can be determined. The refrigeration unit 3 can change its own cooling power according to the first correction coefficient Δ, while the cold storage evaporator 2 can determine the cold release power or cold storage power according to the first correction coefficient Δ and the actual cooling power consumption of the refrigeration unit 3. While using the first correction coefficient Δ to correct the cooling power of the refrigeration unit 3, the cold storage evaporator 2 can also fill the gaps in the stepwise cooling process, thereby making the stepwise cooling process more linear.

[0066] More specifically, in this embodiment, when the first correction coefficient 1≤Δ≤1.2, it can be considered that in the current state, in order to reduce the temperature to the target temperature in a unit of time, the cooling power of the refrigeration unit 3 is too large. Therefore, the cold storage evaporator 2 can store cold in the current time period, so that the first correction coefficient Δ is closer to 1.

[0067] When the first correction coefficient Δ = 1, the secondary actual cooling power consumption equals the primary actual cooling power consumption. At this point, it can be assumed that the sum of the cooling power consumption of the cold storage evaporator 2 and the power consumption of the refrigeration unit 3, or the difference between the cooling power consumption of the refrigeration unit 3 and the cold storage power consumption of the cold storage evaporator 2, is zero. In this case, the temperature drop curve inside the refrigerator is relatively smooth. This can improve the problem of abrupt increases and decreases in the cooling curve caused by design flaws in the feedback regulation mechanism of the existing refrigeration unit 3.

[0068] When the first correction coefficient 0.8 ≤ Δ ≤ 1, it can be considered that the current cooling power consumption of the cold storage evaporator 2 is too high, causing the secondary actual cooling power consumption of the refrigeration unit 3 to be less than the primary actual cooling power consumption. Therefore, for the first correction coefficient Δ, the cooling power consumption of the cold storage evaporator 2 should be reduced to make the secondary actual cooling power consumption of the refrigeration unit 3 closer to the primary actual cooling power consumption, thus making the temperature change curve inside the refrigerator smoother. Of course, the above situation may also be due to the refrigeration unit 3 being insufficient to meet the cooling demand of the refrigerator. In this case, the redundant cooling power consumption of the refrigeration unit 3 should be released through the cooling of the cold storage evaporator 2, satisfying the cooling demand of the refrigerator while making the temperature change inside the refrigerator more linear.

[0069] In some embodiments, the refrigeration unit 3 includes two independently operating compressors 31. If the first correction coefficient Δ > 1, then at least one of the two compressors 31 is turned on.

[0070] In this embodiment, by setting two independently operating compressors 31, the power consumption of the refrigeration unit 3 can be reduced and the energy efficiency ratio of the refrigeration unit 3 can be improved.

[0071] More specifically, in this embodiment, when the first correction coefficient Δ≤1, either of the two compressors 31 can be turned on, or the cold storage evaporator 2 can be turned on alone, so that the sum of the cold release power of the cold storage evaporator 2 and the refrigeration power of the compressor 31 can meet the current refrigeration demand. In addition, turning on only one compressor 31 is more suitable for operating environments with lower refrigeration demand, thereby reducing the power consumption required by the refrigeration unit 3. When the first correction coefficient Δ>1, it can be determined that the current use of the cold storage evaporator 2 alone cannot meet the refrigeration demand of the refrigerator, and more than one compressor 31 needs to be turned on. At this time, the cold storage evaporator 2 can release cold, and together with the compressor 31, it can refrigerate the interior of the cabinet 1. Of course, when both compressors 31 are refrigerating at the same time, the cold storage evaporator 2 can be turned on to store cold to collect the excess refrigeration capacity of the two compressors 31.

[0072] In some embodiments, if the first correction factor is greater than or equal to 1, the cold storage evaporator 2 performs refrigeration; if the first correction factor is less than or equal to 1, the cold storage evaporator 2 stores cold.

[0073] Another object of the present invention is to provide a computer-readable medium storing instructions that, when run on a computer, enable the computer to execute the control logic of the refrigerator as described above.

[0074] Compared to existing technologies, the computer-readable medium in this embodiment, when running in a computer, can make the temperature change curve inside the refrigerator more balanced, thus improving the problem of drastic temperature changes in existing variable frequency refrigerators during operation.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
