[0044] In a first aspect, the embodiments of the present disclosure provide a refrigeration device.

[0045] Combined Figure 1 As shown, the refrigeration device provided by the embodiments of the present disclosure includes a box body 100, a refrigeration unit 200, a sealing structure 300, and an identification component.

[0046] The box body 100 includes a storage cavity 101 and a box body ventilation opening 102, and the box body ventilation opening 102 is communicated with the storage cavity 101. Among them, the box body 100 includes one or more box body ventilation openings 102.

[0047] The refrigeration unit 200 includes an evaporator chamber 201 and a unit ventilation opening 202, the evaporator chamber 201 is communicated with the unit ventilation opening 202, and the unit ventilation opening 202 is correspondingly communicated with the box body ventilation opening 102. The refrigeration unit 200 includes one or more unit ventilation openings 202, and the unit ventilation openings 202 correspond to the box body ventilation openings 102 one by one.

[0048] The sealing structure 300 is arranged at the connection of the box body ventilation opening 102 and the unit ventilation opening 202.

[0049] The identification component is used to detect the distance between the box body ventilation opening 102 and the unit ventilation opening 202 to obtain the extrusion degree of the sealing structure 300.

[0050] The refrigeration device provided by the embodiments of the present disclosure has the box body ventilation opening 102 communicating with the unit ventilation opening 202. By providing a sealing structure at the connection between the box body ventilation opening 102 and the unit ventilation opening 202, the sealed connection between the evaporator chamber 201 and the storage cavity 101 can be achieved. The air flow in the storage cavity 101 flows through the evaporator chamber 201, cools down in the evaporator chamber 201, and then returns to the storage cavity 101, realizing the refrigeration cycle between the refrigeration unit 200 and the box body 100. By detecting the distance between the box body ventilation opening 102 and the unit ventilation opening 202 through the recognition component, the extrusion degree of the sealing structure can be obtained, and thus the sealing effect of the sealing structure can be obtained according to the extrusion degree of the sealing structure. In this way, the accuracy of judging the sealing effect can be improved, and thus the accuracy of the temperature in the storage cavity 101 can be improved.

[0051] It can be understood that the box body ventilation opening 102 is provided on the first box wall of the box body 100, and the unit ventilation opening 202 is provided on the first unit wall of the refrigeration unit 200. Among them, the distance between the box body ventilation opening 102 and the unit ventilation opening 202 is also the distance between the first box wall and the first unit wall.

[0052] In some embodiments, as shown in Figure 2 and Figure 3 , a first magnetic strip 301 is provided inside the sealing structure 300, and the first magnetic strip 301 is located on the first side of the box body ventilation opening 102. The recognition component includes a first sensor 401, and the first sensor 401 is provided on the box body 100 and is located on the first side of the box body ventilation opening 102. The first sensor 401 is used to detect the first distance between the first side of the box body ventilation opening and the first magnetic strip 301.

[0053] By providing the first magnetic strip 301 inside the sealing structure 300 and the first sensor 401 detecting the first distance between the first sensor 401 and the first magnetic strip 301, the distance between the box body ventilation opening 102 and the unit ventilation opening 202 can be calculated, so as to obtain the extrusion degree of the sealing structure 300. In addition, the first magnetic strip is attracted to the first box wall and the first unit wall, which is beneficial to enhancing the sealing performance of the sealing structure 300.

[0054] Optionally, the first magnetic strip 301 is provided in the middle of the sealing structure. That is to say, the distance between the first magnetic strip 301 and the upper surface of the sealing structure is equal to the distance between the first magnetic strip 301 and the lower surface of the sealing structure. With such a setting, it is convenient to calculate the distance between the box body ventilation opening 102 and the unit ventilation opening 202 through the first distance h 1 , and the distance between the box body ventilation opening 102 and the unit ventilation opening 202 is 2h 1 .

[0055] In some embodiments, as shown in Figure 3 and Figure 4As shown, the identification component further includes a second sensor 402. The second sensor 402 is disposed on the box body 100 and is located on the second side of the box body vent 102. The second sensor 402 is used to detect the second distance h between the second side of the box body vent 102 and the first magnetic strip 301. 2 The second side of the box body vent 102 is disposed opposite to the first side of the box body vent 102.

[0056] By measuring the first distance h 1 and the second distance h 2 , the distance l between the second sensor 402 and the first magnetic strip 301 can be calculated 1 , so as to obtain the offset distance of the sealing structure in the first direction, which is convenient for inferring the sealing effect of the sealing structure according to the offset distance, further improving the accuracy of judging the sealing effect, and improving the accuracy of the temperature in the storage cavity 101. Wherein, the first direction is parallel to the straight line where the first sensor 401 and the second sensor 402 are located.

[0057] In some embodiments, a second magnetic strip is further disposed inside the sealing structure 300. The second magnetic strip is located on the third side of the box body vent 102. The third side of the box body vent 102 is adjacent to the first side of the box body vent 102. The identification component includes a third sensor. The third sensor is disposed on the box body 100 and is located on the third side of the box body vent 102. The third sensor is used to detect the third distance between the third side of the box body vent 102 and the second magnetic strip.

[0058] With such a setting, the third sensor can detect the distance between the third side of the box body vent 102 and the second magnetic strip, and the distance between another box body vent 102 and the unit vent 202 can be calculated. Through the calculated multiple distances, the average distance between the box body vent 102 and the unit vent 202 can be calculated, improving the accuracy of judging the extrusion degree of the sealing structure 300.

[0059] In some embodiments, the identification component further includes a fourth sensor. The fourth sensor is disposed on the box body 100 and is located on the fourth side of the box body vent 102. The fourth sensor is used to detect the fourth distance between the fourth side of the box body vent 102 and the second magnetic strip. The fourth side of the box body vent 102 is disposed opposite to the third side of the box body vent 102.

[0060] Through the third distance and the fourth distance, the distance between the fourth sensor and the second magnetic strip can be calculated, so as to obtain the offset distance of the sealing structure in the second direction, which is convenient for inferring the sealing effect of the sealing structure according to the offset distance, further improving the accuracy of judging the sealing effect, and improving the accuracy of the temperature in the storage cavity 101. Wherein, the second direction is parallel to the straight line where the third sensor and the fourth sensor are located.

[0061] In some embodiments, one or more of the first sensor 401, the second sensor 402, the third sensor, and the fourth sensor are Hall sensors. A Hall sensor is a magnetic sensor that is based on the Hall effect. It can sense a magnetic field and changes in the magnetic field, and generally consists of a Hall element and an auxiliary circuit. The Hall element is made of semiconductor material and has the advantages of being sensitive to magnetic fields, having a simple structure, a small volume, a wide frequency response, a large change in output voltage, and a long service life.

[0062] Optionally, the first sensor 401, the second sensor 402, the third sensor, and the fourth sensor are all Hall sensors. The Hall sensors cooperate with the magnetic strip to measure the position of the sealing structure.

[0063] In some embodiments, a third magnetic strip is further provided inside the sealing structure 300, and the third magnetic strip is located on the second side of the box body vent 102. By providing the third magnetic strip, it is convenient to measure the distance between the second side of the box body vent 102 and the second side of the unit vent, so as to improve the accuracy of judging the extrusion degree and the offset distance of the sealing structure 300.

[0064] In some embodiments, a fourth magnetic strip is further provided inside the sealing structure 300, and the fourth magnetic strip is located on the fourth side of the box body vent 102. By providing the fourth magnetic strip, it is convenient to measure the distance between the fourth side of the box body vent 102 and the fourth side of the unit vent, so as to improve the accuracy of judging the extrusion degree and the offset distance of the sealing structure 300.

[0065] In some embodiments, in combination Figure 5 and Figure 6 As shown, the box body vent 102 includes a box body air inlet 1021 and a box body air outlet 1022, and the unit vent 202 includes a unit air inlet 2021 and a unit air outlet 2022. The box body air inlet 1021 is communicated with the unit air outlet 2022, and the box body air outlet 1022 is communicated with the unit air inlet 2021. Sealing structures 300 are provided between the box body air inlet 1021 and the unit air outlet 2022, and between the box body air outlet 1022 and the unit air inlet 2021.

[0066] By providing a sealing structure between the box body air inlet 1021 and the unit air outlet 2022, the box body air inlet 1021 and the unit air outlet 2022 can be hermetically connected. By providing a sealing structure 300 between the box body air outlet 1022 and the unit air inlet 2021, the box body air outlet 1022 and the unit air inlet 2021 can be hermetically connected. In this way, the air flow in the storage cavity 101 flows through the evaporator chamber 201, cools down in the evaporator chamber 201, and then returns to the storage cavity 101, realizing the refrigeration cycle between the refrigeration unit 200 and the box body 100.

[0067] In some embodiments, the sealing structure 300 includes a sealing strip, which is circumferentially arranged around the housing ventilation opening 102 and the unit ventilation opening 202. The sealing strip includes a first sealing strip on the first side of the housing ventilation opening 102, and a first magnetic strip 301 is arranged inside the first sealing strip. The sealing strip includes a second sealing strip on the third side of the housing ventilation opening 102, and a second magnetic strip is arranged inside the second sealing strip. The sealing strip includes a third sealing strip on the second side of the housing ventilation opening 102, and a third magnetic strip is arranged inside the third sealing strip. The sealing strip includes a fourth sealing strip on the fourth side of the housing ventilation opening, and a fourth magnetic strip is arranged inside the fourth sealing strip.

[0068] In some embodiments, in combination Figure 1 As shown, the refrigeration unit 200 is arranged below the housing 100. With this arrangement, when the refrigeration unit 200 is assembled, by designing a lifting frame below the housing 100, the refrigeration unit 200 is placed on the lifting frame, the positions of the refrigeration unit 200 and the housing 100 correspond to each other, and then the lifting frame is lifted to make the housing 100 and the refrigeration unit 200 in sealed communication.

[0069] In some embodiments, in combination Figure 2 and Figure 4 As shown, the refrigeration device further includes one or more heating elements 500. The heating element 500 is arranged on the outer edge of the sealing structure 300, and the heating element 500 is used to heat the sealing structure 300 to relieve the condensation of the sealing structure 300. Under the influence of the temperature difference between the inside and outside of the sealing structure 300 and the external humid and hot air, condensation is likely to occur on the outer side of the sealing structure. By arranging a heating element on the outer edge of the sealing structure and using the heating element to heat the sealing structure, the condensation of the sealing structure can be removed.

[0070] Optionally, the heating element 500 is a heating wire or a refrigeration heat pipe.

[0071] In some embodiments, in combination Figure 1 As shown, the evaporator chamber 201 is provided with an evaporator 2011 and an evaporation fan 2012. The evaporation fan 2012 rotates to make the air flow between the storage cavity 101 and the evaporator chamber 201, realizing the refrigeration cycle between the refrigeration unit 200 and the housing 100. The refrigerant in the evaporator 2011 evaporates and absorbs heat in the evaporator 2011, reducing the surface temperature of the evaporator 2011. The air flow is cooled after flowing through the surface of the evaporator 2011, and then flows to the storage cavity 101, reducing the temperature of the storage cavity 101.

[0072] In some embodiments, in combination Figure 1As shown, the refrigeration unit 200 further includes a compressor compartment 203, in which a compressor, a condenser and a condensing fan are provided. Structures such as the compressor, the condenser and the evaporator cooperate to form a refrigerant circulation loop, so as to reduce the temperature of the evaporator and provide cooling capacity for the storage cavity 101. The condensing fan is used to accelerate the air flow on the surface of the condenser to dissipate heat for the condenser.

[0073] In some embodiments, in combination with Figure 1 As shown, the refrigeration unit 200 further includes a heat insulation layer 600. The heat insulation layer 600 is arranged between the evaporator compartment 201 and the compressor compartment 203. The heat insulation layer 600 can separate the evaporator compartment 201 and the compressor compartment 203, reduce the influence of the compressor compartment 203 on the evaporator compartment 201, and ensure the refrigeration effect of the refrigeration equipment.

[0074] Optionally, the heat insulation layer material includes one or more of foam, foaming material and VIP material (vacuum insulation panel). The materials in the embodiments of the present disclosure all have good heat insulation effects and can all achieve heat insulation for the evaporator compartment 201.

[0075] In a second aspect, an embodiment of the present disclosure provides a method for controlling a refrigeration device.

[0076] In combination with Figure 7 As shown, the method for controlling a refrigeration device includes:

[0077] S101, the refrigeration device detects the distance between the box ventilation opening and the unit ventilation opening.

[0078] S102, when the distance between the box ventilation opening and the unit ventilation opening is greater than a preset distance threshold and less than a first distance threshold, the refrigeration device adjusts the rotation speed of the compressor and the rotation speed of the evaporation fan according to the distance between the box ventilation opening and the unit ventilation opening to meet the refrigeration requirement of the refrigeration device.

[0079] Due to the influence of production and manufacturing processes, such as box foaming and factory assembly, there are certain differences in the distance between the box body of the refrigeration device and the refrigeration unit, and there are certain differences in the extrusion degree of the sealing structure. Since the temperature difference between the inside and outside of the sealing structure is relatively large, the sealing structure needs to meet a certain extrusion degree to ensure a good sealing effect. If the extrusion degree of the sealing structure is too small, it will cause a certain degree of cold leakage. The method for controlling a refrigeration device provided by the embodiments of the present disclosure can judge the extrusion degree of the sealing structure according to the distance between the box ventilation opening and the unit ventilation opening, and adjust the rotation speed of the compressor and the rotation speed of the evaporation fan according to the extrusion degree of the sealing structure, so that the refrigeration device can cool down quickly, improve the accuracy of the temperature of the refrigeration device, and meet the refrigeration requirement of the refrigeration device.

[0080] The distance between the cabinet ventilation opening and the unit ventilation opening is greater than a preset distance threshold and less than a first distance threshold, that is, D 0 <h<D 1 . Wherein, h is the distance between the cabinet ventilation opening and the unit ventilation opening, and D 0 is the preset distance threshold, and D 1 is the first distance threshold.

[0081] Optionally, the preset distance threshold is the preferred distance threshold. When D 2 <h≤D 0 , the sealing effect of the sealing structure can meet the refrigeration requirements of the cabinet.

[0082] Optionally, when h≤D 2 , the refrigeration equipment alarms to indicate an abnormality in the sealing structure, and D 2 <D 0 . When h≤D 2 , the distance between the cabinet ventilation opening and the unit ventilation opening is too small, and the extrusion degree of the sealing structure is too large, that is, the extrusion degree of the sealing structure is close to or exceeds the maximum extrusion degree allowed by the sealing structure, which will cause damage to the sealing structure and affect the sealing performance of the cabinet. Therefore, the refrigeration equipment alarms to indicate an abnormality in the sealing structure and repairs the sealing structure in time.

[0083] Optionally, when h≥D 1 , the refrigeration equipment alarms to indicate an abnormality in the sealing structure. When h≥D 1 , the distance between the cabinet ventilation opening and the unit ventilation opening is too large, and the extrusion degree of the sealing structure is too small, which will cause too much cold leakage of the sealing structure and cannot meet the sealing performance of the cabinet. Therefore, the refrigeration equipment alarms to indicate an abnormality in the sealing structure and repairs the sealing structure in time.

[0084] For example, in the case of no extrusion, the thickness of the sealing structure is 12mm, D 0 is 8mm, D 2 is 5mm, D 1 is 10mm.

[0085] In some embodiments, the refrigeration equipment detects the distance between the cabinet ventilation opening and the unit ventilation opening, including: the refrigeration equipment obtains the first distance between the first magnetic strip and the first side of the cabinet ventilation opening. The refrigeration equipment determines the distance between the cabinet ventilation opening and the unit ventilation opening according to the first distance. With such a setting, the distance between the cabinet ventilation opening and the unit ventilation opening can be obtained more accurately.

[0086] For example, the first magnetic strip 301 is arranged in the middle of the sealing structure, the first distance is h 1 , and the distance between the cabinet ventilation opening 102 and the unit ventilation opening 202 is equal to 2h1 。

[0087] Combined with Figure 8 As shown, an embodiment of the present disclosure provides another method for controlling a refrigeration device, including:

[0112] In the case of Δd 1 <Δh<Δd 2 , the cold leakage of the sealing structure is relatively small, and the speed of the compressor increases by n 1 rps, which can increase the refrigeration capacity, make up for the cold leakage at the sealing structure, and ensure rapid refrigeration of the refrigeration device. In the case of Δd 2 ≤Δh<Δd 3 , the cold leakage of the sealing structure is relatively large, and the speed of the compressor increases by n 2The rps can further increase the refrigerating capacity, make up for the cold leakage at the sealing structure, ensure rapid refrigeration of the refrigeration equipment, and avoid frequent start-stop operations.

[0113] In the case of Δd 1 <Δh<Δd 2 the cold leakage of the sealing structure is relatively small, and the rotational speed of the evaporation fan is increased by m 1 rpm, which can increase the refrigerating capacity, make up for the cold leakage at the sealing structure, and ensure rapid refrigeration of the refrigeration equipment. In the case of Δd 2 ≤Δh<Δd 3 the cold leakage of the sealing structure is relatively large, and the rotational speed of the evaporation fan is increased by m 2 rpm, which can further increase the refrigerating capacity, make up for the cold leakage at the sealing structure, ensure rapid refrigeration of the refrigeration equipment, and avoid frequent start-stop operations.

[0116] By using the method for controlling a refrigeration equipment provided by the embodiments of the present disclosure, the rotational speeds of the compressor and the evaporation fan can be adaptively adjusted according to the cold leakage at the sealing structure, make up for the cold leakage at the sealing structure, ensure rapid refrigeration of the refrigeration equipment, and avoid frequent start-stop operations.

[0117] In some embodiments, the method for controlling a refrigeration equipment further includes: the refrigeration equipment obtains the offset area of the sealing structure. In the case of △S 1 <△S<△S 2 the refrigeration equipment controls the rotational speeds of the compressor and the evaporation fan to increase. In the case of △S≥△S 2 the refrigeration equipment gives an alarm to indicate that the offset area of the sealing structure is too large. Wherein, △S is the offset area of the sealing structure, △S 1 is the first offset area threshold, △S 2 is the second offset area threshold, △S1 <△S 2 。

[0118] Combined Figure 11 As shown, the embodiments of the present disclosure provide another method for controlling a refrigeration device, including:

[0119] S501, the refrigeration device obtains a first distance between a first magnetic strip and a first side of a box body ventilation opening.

[0120] S502, the refrigeration device determines a distance between the box body ventilation opening and the unit ventilation opening according to the first distance.

[0121] S503, the refrigeration device obtains a current distance difference between the distance between the box body ventilation opening and the unit ventilation opening and a preset distance threshold.

[0123] S505, the refrigeration device determines a target adjustment amount of the evaporation fan speed corresponding to the current distance difference according to a positive correlation between the distance difference and the adjustment amount of the evaporation fan speed.

[0124] S506, the refrigeration device adjusts the speed of the compressor and the speed of the evaporation fan according to the target adjustment amount of the compressor speed and the target adjustment amount of the evaporation fan speed.

[0125] S507, the refrigeration device obtains the offset area of the sealing structure.

[0126] S508, in △S 1 <△S<△S 2 In the case of, the refrigeration device controls the speeds of the compressor and the evaporation fan to increase.

[0127] In an ideal situation, the sealing structure is circumferentially arranged around the box body ventilation opening. However, during the assembly process of the refrigeration device, the sealing structure may have a certain offset, thus blocking the box body ventilation opening. In the embodiments of the present disclosure, by obtaining the offset area of the sealing structure and adjusting the speeds of the compressor and the evaporation fan according to the offset area, the influence caused by the blockage of the box body ventilation opening can be compensated, ensuring that the storage cavity of the refrigeration device is quickly cooled and meeting the refrigeration requirements of the refrigeration device.

[0128] In △S 1 <△S<△S 2 In the case of, the offset area of the sealing structure is relatively small, and the refrigeration device controls the speeds of the compressor and the evaporation fan to increase, which can increase the refrigeration capacity, make up for the cold leakage at the sealing structure, and ensure the rapid cooling of the refrigeration device.

[0129] S509, when △S ≥ △S 2 , the refrigeration equipment gives an alarm to indicate that the offset area of the sealing structure is too large.

[0130] When △S2 ≤ △S, the offset area of the sealing structure is relatively large, which will not only block the ventilation opening of the box body, but also affect the sealing effect. The refrigeration equipment gives an alarm to indicate that the offset area of the sealing structure is too large, and the sealing structure is repaired in time.

[0131] The method for controlling a refrigeration device provided by an embodiment of the present disclosure can determine the extrusion degree of a sealing structure according to the distance between a ventilation opening of a box body and a ventilation opening of a unit, and adjust the rotational speeds of a compressor and an evaporation fan according to the extrusion degree of the sealing structure, so that the refrigeration device can cool down quickly, improve the accuracy of the temperature of the refrigeration device, and meet the refrigeration requirements of the refrigeration device. In addition, according to the cold leakage situation of the sealing structure, the condensation situation of the sealing structure can be obtained, and thus the heating power of a heating element can be adaptively adjusted, so that the condensation at the sealing structure can be quickly removed, and the potential safety hazard can be reduced.

[0132] In the embodiment of the present disclosure, the adjustment of the rotational speeds of the compressor and the evaporation fan is a superposition based on "adjusting the rotational speeds of the compressor and the evaporation fan according to the distance between the ventilation opening of the box body and the ventilation opening of the unit". In this way, two factors, namely the offset area of the sealing structure and the current distance difference of the sealing structure, are considered, which is beneficial to improving the accuracy of adjusting the rotational speeds of the compressor and the evaporation fan and meeting the refrigeration requirements of the refrigeration device.

[0133] Optionally, 0 ≤ △S 1 <1 / 10S 0 , 1 / 5S 0 ≤ △S 2 ≤ 1 / 3S 0 , S 0 is the area of the sealing structure. For example, △S 1 is 0, △S 2 is 1 / 3S 0 , when 0 < △S < 1 / 3S 0 , the refrigeration device controls the rotational speeds of the compressor and the evaporation fan to increase. When 1 / 3S 0 ≤ △S, the refrigeration device gives an alarm to indicate that the offset area of the sealing structure is too large.

[0134] In some embodiments, as shown in Figure 12 , obtaining the offset area of the sealing structure includes: the refrigeration device detecting a first offset length △L of the sealing structure along the width direction of the ventilation opening of the box body 1 . The refrigeration device detects a second offset length △L of the sealing structure along the length direction of the ventilation opening of the box body 2According to the following formula, the offset area of the sealing structure is calculated as follows:

[0135] ΔS = ΔL 1 × 2H 1 + ΔL 2 × 2H 2 ;

[0136] In the formula, ΔS is the offset area of the sealing structure, ΔL 1 is the first offset length, H 1 is the length of the sealing structure, ΔL 2 is the second offset length, H 2 is the width of the sealing structure.

[0137] With such a setting, the offset area of the sealing structure can be obtained more accurately, and then the matching condition between the sealing structure and the ventilation opening of the box body can be judged according to the offset area of the sealing structure.

[0138] Combined with the above embodiments, the first sensor 401 is used to detect the first distance h between the first side of the ventilation opening of the box body and the first magnetic strip 301 1 . The second sensor 402 is used to detect the second distance h between the second side of the ventilation opening 102 of the box body and the first magnetic strip 301 2 . Through the first distance h 1 , the second distance h 2 and the Pythagorean theorem, the distance l between the second side of the ventilation opening 102 of the box body and the first magnetic strip 301 can be calculated 1 . Using l 1 - l 0 the first offset length △L in the width direction of the ventilation opening 102 of the box body can be obtained 1 , where l 0 refers to the preset distance between the second side of the ventilation opening 102 of the box body and the first magnetic strip 301.

[0139] The third sensor is used to detect the third distance between the third side of the ventilation opening 102 of the box body and the second magnetic strip. The fourth sensor is used to detect the fourth distance between the fourth side of the ventilation opening 102 of the box body and the second magnetic strip. Through the third distance, the fourth distance and the Pythagorean theorem, the distance between the fourth side of the ventilation opening 102 of the box body and the second magnetic strip can be calculated. Subtracting the preset distance between the fourth side of the ventilation opening 102 of the box body and the second magnetic strip from this distance, the second offset length △L in the length direction of the ventilation opening 102 of the box body can be obtained 2 .

[0140] In some embodiments, the method for controlling the refrigeration device further includes: the refrigeration device obtains the offset volume of the sealing structure. The refrigeration device determines the heating power of the heating element according to the offset volume of the sealing structure.

[0141] The sealing structure mainly includes rubber and an internal airbag, which is used to block the leakage of cold air inside the refrigeration equipment. The heat preservation performance of the sealing structure is poor, so the temperature difference between the inside and outside of the sealing structure is relatively large. When the external environmental temperature of the refrigeration equipment is 30°C and the temperature inside the refrigeration equipment is -18°C, the outer side of the sealing structure contacts the humid and hot air, and condensation will form on the outer side of the sealing structure. The condensed water droplets may flow down to the electrical components of the refrigeration unit, causing potential safety hazards. Therefore, it is necessary to heat the sealing structure to remove the condensation at the sealing structure. In the embodiments of the present disclosure, through the offset volume of the sealing structure, the cold leakage situation of the sealing structure can be obtained, and thus the condensation situation of the sealing structure can be obtained. Accordingly, by adaptively adjusting the heating power of the heating element, the condensation at the sealing structure can be quickly removed, reducing potential safety hazards.

[0142] In some embodiments, obtaining the offset volume of the sealing structure includes: the refrigeration equipment obtains the current distance difference and the offset area of the sealing structure. According to the following formula, the refrigeration equipment calculates the offset volume of the sealing structure:

[0143] ΔV = ΔS×Δh;

[0144] In the formula, ΔV is the offset volume of the sealing structure, ΔS is the offset area of the sealing structure, ΔS is calculated by the formula in the above embodiments and will not be elaborated here, Δh is the current distance difference, and Δh = h - D 0 , where h is the distance between the ventilation opening of the box body and the ventilation opening of the unit, and D 0 is the preset distance threshold.

[0145] When the position and height of the sealing structure shift, the cold leakage amount will change. In the embodiments of the present disclosure, by using two factors, namely the offset area and the current distance difference, to judge the cold leakage situation of the sealing structure is beneficial to improving the accuracy of judging the cold leakage situation of the sealing structure.

[0146] In some embodiments, determining the heating power of the heating element according to the offset volume of the sealing structure includes: when 0 ≤ ΔV < ΔV 1 , the refrigeration equipment controls the heating power of the heating element to be p 1 W. When ΔV 1 ≤ ΔV < ΔV 2 , the refrigeration equipment controls the heating power of the heating element to be p 2 W. When ΔV 2 ≤ ΔV < ΔV 3 , the refrigeration equipment controls the heating power of the heating element to be p 3 W. Among them, ΔV 1 is the first volume threshold, ΔV 2 is the second volume threshold, and ΔV3 is the third volume threshold, ΔV 1 <ΔV 2 <ΔV 3 , p 1 is the first power threshold, p 2 is the second power threshold, p 3 is the third power threshold, p 1 <p 2 <p 3 .

[0147] When 0 ≤ ΔV < ΔV 1 , the cold leakage of the sealing structure is relatively small, the condensation at the sealing structure is relatively light, and the heating power of the heating element is p 1 W, and the condensation at the heating element can be quickly removed, and the influence on the temperature inside the refrigeration equipment can be reduced. When ΔV 1 ≤ ΔV < ΔV 2 , the cold leakage of the sealing structure is relatively large, the condensation at the sealing structure is relatively heavy, and the heating power of the heating element is p 2 W, and the condensation at the heating element can be quickly removed. When ΔV 2 ≤ ΔV < ΔV 3 , the cold leakage of the sealing structure is large, and the heating power of the heating element is p 3 W, and the condensation at the heating element can be quickly removed.

[0148] For example, ΔV 1 is 1400mm 3 , ΔV 2 is 2400mm 3 , ΔV 3 is 5600mm 3 , p 1 is 10W, p 2 is 15W, p 3 is 25W.

[0149] Optionally, the heating power of the heating element can be adjusted by changing the voltage applied to the heating element, and thus the power of the heating element can be changed.

[0150] Optionally, the refrigeration equipment includes a first heating element and a second heating element. The heating powers of the first heating element and the second heating element are different, one of which is a high-power heating element and the other is a low-power heating element. By controlling the switching of the high-power and low-power heating elements to work, three heating effects can be achieved: only the first heating element works, only the second heating element works, and the first heating element and the second heating element work together. In this way, the computer board hardware design is simple, and the heating gear switching can be controlled only by a switching signal, which is beneficial to saving the design power of the switching power supply.
