[0002] In related technologies, during cold chain transportation, in order to ensure the freezing or refrigeration requirements of materials, the refrigeration unit needs to operate continuously to maintain the low temperature environment in the cargo hold, resulting in technical problems such as high energy consumption and poor economic efficiency in cold chain transportation products.

[0003] Therefore, overcoming the aforementioned technical deficiencies has become an urgent technical problem to be solved. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art.

[0005] Therefore, the first aspect of this application proposes a refrigeration device.

[0006] The second aspect of this application proposes a vehicle.

[0007] The third aspect of this application proposes a control method for a refrigeration device.

[0008] The fourth aspect of this application proposes a control device for a refrigeration equipment.

[0009] The fifth aspect of this application proposes a control device for a refrigeration equipment.

[0010] The sixth aspect of this application proposes a readable storage medium.

[0011] The seventh aspect of this application proposes a refrigeration device.

[0012] The eighth aspect of this application proposes a vehicle.

[0013] In view of the above, a first aspect of this application provides a refrigeration device, comprising: a housing including a first cavity and an opening; a door assembly disposed on the housing for opening or closing the opening; a refrigeration assembly disposed on the housing for cooling the first cavity; a fan disposed on the housing for generating airflow within the first cavity; a sensor disposed on the housing for detecting the ambient temperature outside the housing; and a controller connected to the door assembly, the refrigeration assembly, the fan, and the sensor, wherein the controller controls the operating state of the refrigeration assembly and the fan according to the ambient temperature when the door assembly is open.

[0014] This application defines a refrigeration device that can be applied to cold chain transportation. The refrigeration device includes a housing, a door assembly, and a refrigeration component. The housing is the main frame structure of the refrigeration device, and a first cavity for storing materials is enclosed within the housing. An opening is provided on the cavity to communicate with the first cavity, through which materials are stored in or removed from the first cavity.

[0015] The door assembly is installed at the opening on the container body. The door assembly can open or close the opening. During transportation, the door assembly is in the closed state, and when loading and unloading goods, the door assembly is in the open state.

[0016] The refrigeration unit is installed on the cabinet. The refrigeration unit can cool the first cavity through the refrigerant heat exchange principle to maintain the low temperature environment in the first cavity and meet the low temperature refrigeration or low temperature freezing requirements of materials.

[0017] In addition, the refrigeration equipment also includes a fan, sensors, and a controller. The fan is mounted on the enclosure. When turned on, the fan generates airflow within the first chamber. Specifically, the fan can drive the circulation of gas within the first chamber, or it can deliver gas into or extract gas from the first chamber. The sensor is mounted on the outside of the enclosure. The sensor is used to detect the ambient temperature outside the enclosure, which is typically the outdoor temperature during cold chain transportation.

[0018] The controller connects to sensors, the door assembly, the refrigeration assembly, and the fan, and controls the operation of the refrigeration and fan assemblies. The controller receives electrical signals from the door assembly and determines its status based on these signals. When the controller determines the door assembly is open, it obtains the ambient temperature outside the enclosure via sensors and then controls the operation of the refrigeration assembly and fan based on this temperature. Specifically, when the controller determines the ambient temperature outside the enclosure is low enough to meet freezing or refrigeration requirements, it increases the fan speed and reduces or shuts down the refrigeration assembly. This increases the airflow generated by the fan, accelerating the ventilation between the inside and outside of the enclosure to quickly introduce low-temperature gas from outside. When the controller determines the ambient temperature outside the enclosure is high enough to not meet freezing or refrigeration requirements, it reduces the fan speed or shuts down and increases the power of the refrigeration assembly. This reduces the ventilation efficiency between the inside and outside of the enclosure, preventing the rapid introduction of high-temperature gas from outside and disrupting the low-temperature environment of the first chamber, while maintaining the low-temperature environment through the high-power operation of the refrigeration assembly.

[0019] Therefore, this application, through the coordinated control of the door assembly, fan, and refrigeration components, can, on the one hand, rationally utilize the low-temperature gas outside the container to refrigerate the interior in low-temperature environments, thereby reducing compressor energy consumption. On the other hand, it can reduce the air exchange efficiency between the inside and outside of the container in high-temperature environments, preventing external high-temperature gas from affecting the freezing or refrigeration effect of goods, and also helps reduce the energy consumption of the refrigeration components to compensate for the inflow of hot air. This solves the technical problems of high energy consumption and poor economic efficiency in cold chain transportation existing in related technologies. Furthermore, it achieves the technical effects of optimizing the refrigeration equipment structure, reducing refrigeration equipment energy consumption, and improving the practicality and reliability of the refrigeration equipment.

[0020] In addition, the refrigeration equipment provided in this application may also have the following additional technical features:

[0021] In the above technical solution, the refrigeration component includes: a first heat exchanger disposed inside the housing; a second heat exchanger disposed outside the housing and connected to the first heat exchanger; and a compressor disposed outside the housing and connected to the second heat exchanger.

[0022] In this technical solution, the refrigeration assembly includes a first heat exchanger, a second heat exchanger, and a compressor. The first heat exchanger is located inside a first chamber, while the second heat exchanger and the compressor are located outside the chamber. These components form a refrigerant circulation path. The refrigerant evaporates and absorbs heat in the first heat exchanger, thereby lowering the temperature inside the first chamber and achieving a refrigeration effect. A controller is connected to the compressor and can control the compressor's start and stop based on the ambient temperature. By incorporating the refrigeration assembly, a low-temperature environment can be maintained inside the first chamber, ensuring that materials remain in a frozen or refrigerated state during transportation.

[0023] In any of the above technical solutions, the fan includes: a first fan, disposed in the first heat exchanger.

[0024] In this technical solution, the fan includes a first fan mounted on a first heat exchanger. When the first fan is turned on, it generates airflow through the heat exchanger, which improves the heat exchange efficiency of the first heat exchanger within the first cavity, thereby enhancing the cooling effect of the refrigeration components. When the door assembly is open and the external ambient temperature meets the refrigeration or freezing requirements, turning on the first fan accelerates the outflow rate of gas inside the first cavity and the inflow rate of external gas, thus utilizing external cooling capacity more efficiently by increasing the airflow exchange rate. Conversely, when the door assembly is open and the ambient temperature is high, the controller controls the first fan to slow down or stop, reducing the cooling capacity loss by decreasing the gas exchange rate within the first cavity. This achieves the technical effects of reducing energy consumption of the refrigeration equipment and lowering cold chain transportation costs.

[0025] In any of the above technical solutions, the enclosure includes a fresh air inlet, and the fan also includes a second fan, which is located in the enclosure and is positioned opposite to the fresh air inlet.

[0026] In this technical solution, the enclosure is also equipped with a fresh air inlet connecting the first cavity to the outside of the enclosure. Furthermore, a second fan is included, mounted on the enclosure and positioned opposite the fresh air inlet. When activated, the second fan can draw gas from the first cavity through the fresh air inlet or blow external gas into the first cavity through the same inlet. For example, when the external ambient temperature is low and the enclosure door is open, controlling the second fan to draw gas from the first cavity and allowing external gas to flow into it accelerates the ventilation efficiency of the first cavity, thus making efficient use of the external cooling capacity. Conversely, when the external ambient temperature is high and the enclosure door is open, controlling the second fan to operate at low speed or shutting it off reduces the ventilation efficiency of the first cavity, preventing excessive external gas from disrupting the low-temperature environment within the first cavity. This achieves the technical effect of reducing energy consumption of the refrigeration equipment and lowering cold chain transportation costs.

[0027] Specifically, when it is necessary to improve the air exchange efficiency inside and outside the box, the controller can control at least one of the first fan and the second fan to work; when it is necessary to reduce the air exchange efficiency inside and outside the box, the controller can shut down the first fan and / or the second fan.

[0028] In any of the above technical solutions, the refrigeration equipment further includes: a housing, disposed in the box and located outside the first cavity, including an air exchange port; and a third heat exchanger, disposed inside the housing, the third heat exchanger dividing the housing into a second cavity and a third cavity, the second cavity being connected to the air exchange port and the third cavity being connected to the fresh air inlet.

[0029] In this technical solution, the refrigeration equipment also includes a housing and a third heat exchanger. The housing is installed on the outside of the enclosure, and the third heat exchanger is located inside the housing. The housing has an air vent, and the third heat exchanger divides the space inside the housing into a second chamber and a third chamber. The second chamber is connected to the air vent, and the third chamber is connected to the first chamber through a fresh air inlet. When the external ambient temperature is lower than the internal temperature of the first chamber, the third heat exchanger releases heat towards the second chamber and absorbs heat towards the third chamber. At this time, turning on the second fan increases the gas exchange rate between the third and first chambers, thereby introducing external cooling energy into the first chamber. If the door assembly is open at this time, the controller can also simultaneously control the first fan to turn on, accelerating the gas exchange rate at the opening through the airflow generated by the first fan. This achieves the technical effect of reducing energy consumption of the refrigeration equipment and reducing cold chain transportation costs.

[0030] In any of the above technical solutions, the door assembly includes: a door body, hinged to the cabinet body; and a micro switch, located in the cabinet body and connected to the controller, which is triggered when the door body closes the opening.

[0031] In this technical solution, the door assembly includes a door body and a micro switch. Specifically, the door body is hinged to the cabinet body, and the opening can be opened or closed by rotating the door body. The micro switch is located at the opening and faces the door body. When the door body is in the closed state, the micro switch contacts the door body and is in a triggered state. When the door body is in the open state, the door body separates from the micro switch, and the micro switch is in a non-triggered state. The controller can then determine whether the door assembly has switched from the closed state to the open state based on the change in the electrical signal. By setting up the micro switch, the controller can detect the open / closed state of the door assembly, so as to introduce external low-temperature air in a timely manner when the door assembly is open, or reduce the leakage rate of internal low-temperature air. This achieves the technical effect of improving the automation level of the refrigeration equipment and reducing the energy consumption of the refrigeration equipment.

[0032] A second aspect of this application provides a vehicle comprising: a vehicle body; and a refrigeration device, as described in any of the above technical solutions, disposed on the vehicle body.

[0033] This technical solution defines a vehicle that includes the refrigeration equipment in any of the above technical solutions. Therefore, the vehicle possesses the advantages of the refrigeration equipment in any of the above technical solutions and can achieve the technical effects that the refrigeration equipment in any of the above technical solutions can achieve. To avoid repetition, it will not be described in detail here.

[0034] In addition, the vehicle also includes a body, and the refrigeration equipment is installed on the body so that the refrigeration equipment can move with the body, thereby taking into account both low-temperature storage and transportation needs.

[0035] The third aspect of this application provides a control method for a refrigeration device, used to control the refrigeration device in any of the above technical solutions. The control method for the refrigeration device includes: acquiring the ambient temperature outside the cabinet based on the door assembly being in an open state; and controlling the working state of the refrigeration components and the fan according to the ambient temperature.

[0036] This technical solution proposes a control method for controlling the operation of refrigeration equipment in any of the above technical solutions.

[0037] The refrigeration equipment includes a housing, a door assembly, and a refrigeration unit. The housing is the main frame structure of the refrigeration equipment, and a first cavity for storing materials is enclosed inside the housing. An opening is provided on the cavity to connect with the first cavity, through which materials are stored in or taken out of the first cavity.

[0038] The door assembly is installed at the opening on the container body. The door assembly can open or close the opening. During transportation, the door assembly is in the closed state, and when loading and unloading goods, the door assembly is in the open state.

[0039] The refrigeration unit is installed on the cabinet. The refrigeration unit can cool the first cavity through the refrigerant heat exchange principle to maintain the low temperature environment in the first cavity and meet the low temperature refrigeration or low temperature freezing requirements of materials.

[0040] In addition, the refrigeration equipment also includes a fan and sensors. The fan is mounted on the enclosure. When turned on, the fan generates airflow within the first chamber. Specifically, the fan can drive the circulation of gas within the first chamber, or it can deliver gas into or extract gas from the first chamber. The sensor is mounted on the outside of the enclosure. The sensor is used to detect the ambient temperature outside the enclosure, which is typically the outdoor temperature during cold chain transportation.

[0041] During the operation of the refrigeration equipment, when the door assembly is confirmed to be open, the ambient temperature outside the chamber is acquired via sensors. The operating status of the refrigeration components and fans is then controlled based on this ambient temperature. Specifically, if the ambient temperature outside the chamber is low enough to meet freezing or refrigeration requirements, the fan speed is increased, and the refrigeration components are reduced in power or shut down. This airflow generated by the fan accelerates the ventilation efficiency between the inside and outside of the chamber, quickly introducing low-temperature gas from outside. Conversely, if the ambient temperature outside the chamber is high enough to fail to meet freezing or refrigeration requirements, the fan speed is reduced or shut down, and the refrigeration components are increased in power. This reduces the ventilation efficiency between the inside and outside of the chamber, preventing the rapid introduction of high-temperature gas from disrupting the low-temperature environment of the first chamber, while maintaining the low-temperature environment through the high-power operation of the refrigeration components.

[0042] Therefore, this application, by defining the aforementioned control method, can, on the one hand, rationally utilize the low-temperature gas outside the container to refrigerate the interior in low-temperature environments, thereby reducing compressor energy consumption. On the other hand, it can reduce the air exchange efficiency between the inside and outside of the container in high-temperature environments, preventing external high-temperature gas from affecting the freezing or refrigeration effect of goods, and also helps reduce the energy consumption of the refrigeration components to compensate for the inflow of hot air. This solves the technical problems of high energy consumption and poor economic efficiency in cold chain transportation existing in related technologies. Furthermore, it achieves the technical effects of optimizing the structure of refrigeration equipment, reducing energy consumption of refrigeration equipment, and improving the practicality and reliability of refrigeration equipment.

[0043] In any of the above technical solutions, controlling the operating status of the cooling components and the fan according to the ambient temperature includes: when the ambient temperature matches the target temperature range, turning off the cooling components and controlling the fan to increase its speed; when the ambient temperature does not match the target temperature range, controlling the fan to decrease its speed.

[0044] This technical solution explains the step of controlling the operating status of the refrigeration components and the fan based on the ambient temperature. Specifically, after obtaining the ambient temperature, it is compared with a target temperature range. If the ambient temperature is within the target temperature range, it is considered a match between the target and ambient temperatures. The refrigeration components are then shut down, and the fan speed is increased. This reduces energy consumption by shutting down the refrigeration components and utilizes external cooling capacity efficiently by increasing the fan speed. Conversely, if the ambient temperature is outside the target temperature range, it is considered a mismatch between the target and ambient temperatures. The fan speed is then reduced to decrease the airflow exchange rate between the inside and outside of the enclosure, preventing rapid loss of internal cooling capacity.

[0045] Specifically, the target temperature range can be an open range containing only the maximum temperature or a closed range. For example, when refrigeration equipment needs to refrigerate materials, the target temperature range is a closed range. If the ambient temperature is higher than the maximum temperature, the internal cooling loss needs to be reduced by decreasing the internal and external air exchange rates. If the ambient temperature is lower than the maximum temperature, the internal and external air exchange rates need to be reduced to prevent the temperature of the first chamber from becoming too low and to prevent the refrigerated materials from freezing. This achieves the technical effects of rationally utilizing external cooling capacity, improving the refrigeration reliability of the equipment, and reducing the energy consumption of the refrigeration equipment.

[0046] In any of the above technical solutions, before the step of controlling the working state of the refrigeration components and the fan according to the ambient temperature, the control method further includes: determining the target temperature range according to the working mode of the refrigeration equipment.

[0047] In this technical solution, before controlling the working status of the refrigeration components and the fan according to the ambient temperature, the target temperature range is first determined according to the working mode of the refrigeration equipment. Different working modes correspond to different target temperature ranges, thereby ensuring the rational utilization of the cooling capacity of the external environment by the refrigeration equipment and avoiding adverse effects of external air on the refrigeration process.

[0048] Specifically, the refrigeration equipment includes two operating modes: refrigeration mode and freezing mode. A first set temperature is pre-stored for refrigeration mode, and a second set temperature is set for freezing mode. When the current operating mode is determined to be refrigeration mode, the corresponding first target temperature range is greater than or equal to -1℃ and less than or equal to (A+2)℃, where A is the first set temperature, which is taken from the nationally stipulated refrigeration temperature range. When the current operating mode is determined to be freezing mode, the corresponding second target temperature range is greater than or equal to (B-5)℃ and less than or equal to (B+2)℃, where B is the second set temperature, which is taken from the nationally stipulated freezing temperature range.

[0049] The fourth aspect of this application provides a control device for a refrigeration device, used to control the refrigeration device as described in any of the above technical solutions. The control device for the refrigeration device includes: an acquisition module for acquiring the ambient temperature outside the cabinet based on the door assembly being in an open state; and a control module for controlling the operating state of the refrigeration components and the fan according to the ambient temperature.

[0050] This technical solution defines a control device for controlling the operation of the refrigeration equipment in any of the above technical solutions.

[0051] The refrigeration equipment includes a housing, a door assembly, and a refrigeration unit. The housing is the main frame structure of the refrigeration equipment, and a first cavity for storing materials is enclosed inside the housing. An opening is provided on the cavity to connect with the first cavity, through which materials are stored in or taken out of the first cavity.

[0052] The door assembly is installed at the opening on the container body. The door assembly can open or close the opening. During transportation, the door assembly is in the closed state, and when loading and unloading goods, the door assembly is in the open state.

[0053] The refrigeration unit is installed on the cabinet. The refrigeration unit can cool the first cavity through the refrigerant heat exchange principle to maintain the low temperature environment in the first cavity and meet the low temperature refrigeration or low temperature freezing requirements of materials.

[0054] In addition, the refrigeration equipment also includes a fan and sensors. The fan is mounted on the enclosure. When turned on, the fan generates airflow within the first chamber. Specifically, the fan can drive the circulation of gas within the first chamber, or it can deliver gas into or extract gas from the first chamber. The sensor is mounted on the outside of the enclosure. The sensor is used to detect the ambient temperature outside the enclosure, which is typically the outdoor temperature during cold chain transportation.

[0055] The control unit of the refrigeration equipment includes an acquisition module and a control module. When the door assembly is determined to be open, the acquisition module acquires the ambient temperature outside the chamber via a sensor. The control module then controls the operation of the refrigeration components and the fan based on the ambient temperature. Specifically, when the ambient temperature outside the chamber is determined to be low enough to meet freezing or refrigeration requirements, the fan speed is increased, and the refrigeration components are controlled to reduce power or shut down. This increases the airflow generated by the fan, accelerating the ventilation efficiency between the inside and outside of the chamber to quickly introduce low-temperature gas from outside. When the ambient temperature outside the chamber is determined to be high enough to not meet freezing or refrigeration requirements, the fan speed is reduced or shut down, and the refrigeration components are controlled to increase power. This reduces the ventilation efficiency between the inside and outside of the chamber, preventing the rapid introduction of high-temperature gas from outside and disrupting the low-temperature environment of the first chamber. Simultaneously, the high-power operation of the refrigeration components maintains the low-temperature environment.

[0056] Therefore, this application, by defining the control device of the aforementioned refrigeration equipment, can, on the one hand, rationally utilize the low-temperature gas outside the container to refrigerate the interior in low-temperature environments, thereby reducing the energy consumption of the compressor. On the other hand, it can reduce the air exchange efficiency between the inside and outside of the container in high-temperature environments, preventing the high-temperature external gas from affecting the freezing or refrigeration effect of goods, and also helps to reduce the energy consumption of the refrigeration components to compensate for the inflow of hot air. This solves the technical problems of high energy consumption and poor economic efficiency in cold chain transportation existing in related technologies. Furthermore, it achieves the technical effects of optimizing the structure of refrigeration equipment, reducing its energy consumption, and improving its practicality and reliability.

Detailed Implementation

[0075] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0076] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0077] The following reference Figures 1 to 7 This application describes a refrigeration device, control method, apparatus, readable storage medium, and vehicle according to some embodiments thereof.

[0078] like Figure 1 As shown, one embodiment of this application proposes a refrigeration device 100, which includes: a housing 110, including a first cavity 1102 and an opening 1104; a door assembly 120, disposed in the housing 110, for opening or closing the opening 1104; a refrigeration assembly 130, disposed in the housing 110, for refrigerating the first cavity 1102; a fan 140, disposed in the housing 110, for generating airflow in the first cavity 1102; a sensor 150, disposed in the housing 110, for detecting the ambient temperature outside the housing 110; and a controller 160, connected to the door assembly 120, the refrigeration assembly 130, the fan 140, and the sensor 150, wherein the controller 160 controls the operating state of the refrigeration assembly 130 and the fan 140 according to the ambient temperature when the door assembly 120 is open.

[0079] This application defines a refrigeration device 100 that can be applied to cold chain transportation. The refrigeration device 100 includes a housing 110, a door assembly 120, and a refrigeration assembly 130. The housing 110 is the main frame structure of the refrigeration device 100. The housing 110 encloses a first cavity 1102 for storing materials, and the cavity has an opening 1104 communicating with the first cavity 1102. Materials are stored in the first cavity 1102 through the opening 1104 or taken out of the first cavity 1102 through the opening 1104.

[0080] The door assembly 120 is installed at the opening 1104 on the container body 110. The door assembly 120 can open or close the opening 1104. During transportation, the door assembly 120 is in the closed state, and when loading and unloading goods, the door assembly 120 is in the open state.

[0081] The refrigeration component 130 is installed on the housing 110. The refrigeration component 130 can refrigerate the first cavity 1102 through the refrigerant heat exchange principle to maintain the low temperature environment in the first cavity 1102 and meet the low temperature refrigeration or low temperature freezing requirements of materials.

[0082] Based on this, the refrigeration equipment 100 also includes a fan 140, a sensor 150, and a controller 160. The fan 140 is mounted on the housing 110. When the fan 140 is turned on, it generates airflow within the first cavity 1102. Specifically, the fan 140 can drive the gas circulation within the first cavity 1102, or it can deliver gas into or extract gas from the first cavity 1102. The sensor 150 is mounted on the outside of the housing 110. The sensor 150 is used to detect the ambient temperature outside the housing 110. During cold chain transportation, this ambient temperature is usually the outdoor ambient temperature.

[0083] The controller 160 is connected to the sensor 150, the door assembly 120, the refrigeration assembly 130, and the fan 140, and controls the operation of the refrigeration assembly 130 and the fan 140. The controller 160 can obtain an electrical signal from the door assembly 120 and determine its state based on this signal. When the controller 160 determines that the door assembly 120 is open, it obtains the ambient temperature outside the cabinet 110 through the sensor 150, and then controls the operation of the refrigeration assembly 130 and the fan 140 based on the ambient temperature. Specifically, when the controller 160 determines that the ambient temperature outside the cabinet 110 is low enough to meet freezing or refrigeration requirements, it controls the fan 140 to increase its speed and controls the refrigeration assembly 130 to reduce its power or shut down. This increases the airflow generated by the fan 140, improving the ventilation efficiency inside and outside the cabinet 110 and quickly introducing low-temperature gas from outside the cabinet 110. When the controller 160 determines that the ambient temperature outside the cabinet 110 is too high to meet the freezing or refrigeration requirements, the controller 160 controls the fan 140 to reduce the fan speed or turn it off, and controls the refrigeration component 130 to increase the power, thereby reducing the air exchange efficiency inside and outside the cabinet 110, avoiding the rapid introduction of high-temperature external gas that could damage the low-temperature environment of the first cavity 1102, while maintaining the low-temperature environment through the high-power operation of the refrigeration component 130.

[0084] Therefore, this application, through the coordinated control of the door assembly 120, the fan 140, and the refrigeration assembly 130, can, on the one hand, rationally utilize the low-temperature gas outside the container 110 to refrigerate the interior in low-temperature environments, thereby reducing the energy consumption of the compressor 136. On the other hand, it can reduce the air exchange efficiency inside and outside the container 110 in high-temperature environments, preventing the external high-temperature gas from affecting the freezing or refrigeration effect of goods, and also helps to reduce the energy consumption of the refrigeration assembly 130 in compensating for the inflow of hot air. This solves the technical problems of high energy consumption and poor economic efficiency in cold chain transportation in related technologies. Furthermore, it achieves the technical effects of optimizing the structure of the refrigeration equipment 100, reducing the energy consumption of the refrigeration equipment 100, and improving the practicality and reliability of the refrigeration equipment 100.

[0085] like Figure 1 As shown, in the above embodiment, the refrigeration assembly 130 includes: a first heat exchanger 132 disposed inside the housing 110; a second heat exchanger 134 disposed outside the housing 110 and connected to the first heat exchanger 132; and a compressor 136 disposed outside the housing 110 and connected to the second heat exchanger 134.

[0086] In this embodiment, the refrigeration assembly 130 includes a first heat exchanger 132, a second heat exchanger 134, and a compressor 136. The first heat exchanger 132 is disposed inside the first cavity 1102, while the second heat exchanger 134 and the compressor 136 are disposed outside the housing 110. The first heat exchanger 132, the second heat exchanger 134, and the compressor 136 form a refrigerant circulation path. The refrigerant evaporates and absorbs heat in the first heat exchanger 132 to lower the temperature inside the first cavity 1102, thereby achieving a refrigeration effect. A controller 160 is connected to the compressor 136 and can control the start and stop of the compressor 136 according to the ambient temperature. By setting up the refrigeration assembly 130, a low-temperature environment can be maintained inside the first cavity 1102 to ensure that the materials can be kept in a frozen or refrigerated state during transportation.

[0087] like Figure 1 As shown, in any of the above embodiments, the fan 140 includes: a first fan 142, disposed in the first heat exchanger 132.

[0088] In this embodiment, the fan 140 includes a first fan 142, which is mounted on the first heat exchanger 132. When the first fan 142 is turned on, it generates airflow through the first heat exchanger 132. This airflow improves the heat exchange efficiency of the first heat exchanger 132 within the first cavity 1102, thereby enhancing the cooling effect of the refrigeration assembly 130. When the door assembly 120 is open and the external ambient temperature meets the refrigeration or freezing requirements, turning on the first fan 142 accelerates the outflow rate of gas inside the first cavity 1102 and the inflow rate of external gas, thus utilizing external cooling capacity more efficiently by increasing the airflow exchange rate. Correspondingly, when the door assembly 120 is open and the ambient temperature is high, the controller 160 controls the first fan 142 to slow down or stop, thereby reducing cooling capacity loss by decreasing the gas exchange rate inside and outside the first cavity 1102. This achieves the technical effects of reducing the energy consumption of the refrigeration equipment 100 and reducing cold chain transportation costs.

[0089] like Figure 2 As shown, in any of the above embodiments, the housing 110 includes a fresh air inlet 1106, and the fan 140 further includes a second fan 144, which is disposed in the housing 110 and is disposed opposite to the fresh air inlet 1106.

[0090] In this embodiment, the housing 110 is further provided with a fresh air inlet 1106 connecting the first cavity 1102 and the outside of the housing 110. In addition, the fan 140 includes a second fan 144, which is mounted on the housing 110 and positioned opposite the fresh air inlet 1106. When activated, the second fan 144 can draw gas from the first cavity 1102 through the fresh air inlet 1106, or blow external gas into the first cavity 1102 through the fresh air inlet 1106. For example, when the external ambient temperature is low and the door assembly 120 is open, by controlling the second fan 144 to draw gas from the first cavity 1102, and allowing external gas to flow into the first cavity 1102 through the opening 1104, the ventilation efficiency of the first cavity 1102 is accelerated, thus making efficient use of the external cooling capacity of the housing 110 by rapidly introducing external gas. Correspondingly, when the external ambient temperature is high and the door assembly 120 is open, the second fan 144 is controlled to operate at low speed or is turned off to reduce the air exchange efficiency of the first cavity 1102 and prevent excessive external gas from disrupting the low-temperature environment inside the first cavity 1102. This achieves the technical effect of reducing the energy consumption of the refrigeration equipment 100 and reducing cold chain transportation costs.

[0091] Specifically, when it is necessary to improve the ventilation efficiency inside and outside the housing 110, the controller 160 can control at least one of the first fan 142 and the second fan 144 to work, and when it is necessary to reduce the ventilation efficiency inside and outside the housing 110, the controller 160 can shut down the first fan 142 and / or the second fan 144.

[0092] like Figure 3 As shown, in any of the above embodiments, the refrigeration device 100 further includes: a housing 170 disposed in the box 110 and located outside the first cavity 1102, including an air exchange port 1702; and a third heat exchanger 172 disposed inside the housing 170, wherein the third heat exchanger 172 divides the housing 170 into a second cavity 1704 and a third cavity 1706, the second cavity 1704 being connected to the air exchange port 1702 and the third cavity 1706 being connected to the fresh air inlet 1106.

[0093] In this embodiment, the refrigeration device 100 further includes a housing 170 and a third heat exchanger 172. The housing 170 is installed on the outside of the casing 110, and the third heat exchanger 172 is disposed inside the housing 170. The housing 170 has a ventilation port 1702, and the third heat exchanger 172 divides the space inside the housing 170 into a second cavity 1704 and a third cavity 1706. The second cavity 1704 communicates with the ventilation port 1702, and the third cavity 1706 is connected to the first cavity 1102 through a fresh air inlet 1106. When the external ambient temperature is lower than the internal temperature of the first cavity 1102, the third heat exchanger 172 releases heat towards the side facing the second cavity 1704 and absorbs heat towards the side facing the third cavity 1706. At this time, turning on the second fan 144 can increase the gas exchange rate between the third cavity 1706 and the first cavity 1102, thereby introducing external cold energy into the first cavity 1102. If the door assembly 120 is open at this time, the controller 160 can also simultaneously control the first fan 142 to turn on, so as to accelerate the gas exchange rate at the opening 1104 through the airflow generated by the first fan 142, thereby achieving the technical effect of reducing the energy consumption of the refrigeration equipment 100 and reducing the cost of cold chain transportation.

[0094] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of this application, the door assembly 120 includes: a door body 122, which is hinged to the box body 110; and a micro switch 124, which is disposed in the box body 110 and connected to the controller 160, and is triggered when the door body 122 closes the opening 1104.

[0095] In this embodiment, the door assembly 120 includes a door body 122 and a micro switch 124. Specifically, the door body 122 is hinged to the housing 110, and the opening 1104 can be opened or closed by rotating the door body 122. The micro switch 124 is located at the opening 1104 and faces the door body 122. When the door body 122 is in the closed state, the micro switch 124 contacts the door body 122 and is in a triggered state. When the door body 122 is in the open state, the door body 122 is separated from the micro switch 124, and the micro switch 124 is in a non-triggered state. The controller 160 can then determine the switch of the door assembly 122 from the closed state to the open state based on the change in the electrical signal. By setting the micro switch 124, the controller 160 can detect the open / closed state of the door assembly 120, so as to introduce external low-temperature air in a timely manner when the door assembly 120 is opened, or reduce the leakage rate of internal low-temperature air. This will achieve the technical effect of improving the automation level of refrigeration equipment and reducing the energy consumption of refrigeration equipment.

[0096] like Figure 4As shown, one embodiment of this application provides a vehicle 200, which includes: a vehicle body 210; and a refrigeration device 100 as described in any of the above embodiments, disposed on the vehicle body 210.

[0097] In this embodiment, a vehicle 200 including the refrigeration device 100 in any of the above embodiments is defined. Therefore, the vehicle 200 has the advantages of the refrigeration device 100 in any of the above embodiments and can achieve the technical effects that the refrigeration device 100 in any of the above embodiments can achieve. To avoid repetition, it will not be described again here.

[0098] Based on this, the vehicle 200 also includes a vehicle body 210, and a refrigeration device 100 is installed on the vehicle body 210 so that the refrigeration device 100 can move with the vehicle body 210, thereby taking into account both low-temperature storage and transportation needs.

[0099] like Figure 5 As shown, one embodiment of this application provides a control method for a refrigeration device, used to control the refrigeration device in any of the above embodiments. The control method for the refrigeration device includes:

[0100] Step 502: Based on the fact that the door assembly is in the open state, obtain the ambient temperature outside the enclosure;

[0101] Step 504: Control the operating status of the refrigeration components and the fan according to the ambient temperature.

[0102] In this embodiment, a control method for controlling the operation of the refrigeration equipment in any of the above embodiments is proposed.

[0103] The refrigeration equipment includes a housing, a door assembly, and a refrigeration unit. The housing is the main frame structure of the refrigeration equipment, and a first cavity for storing materials is enclosed inside the housing. An opening is provided on the cavity to connect with the first cavity, through which materials are stored in or taken out of the first cavity.

[0104] The door assembly is installed at the opening on the container body. The door assembly can open or close the opening. During transportation, the door assembly is in the closed state, and when loading and unloading goods, the door assembly is in the open state.

[0105] The refrigeration unit is installed on the cabinet. The refrigeration unit can cool the first cavity through the refrigerant heat exchange principle to maintain the low temperature environment in the first cavity and meet the low temperature refrigeration or low temperature freezing requirements of materials.

[0106] In addition, the refrigeration equipment also includes a fan and sensors. The fan is mounted on the enclosure. When turned on, the fan generates airflow within the first chamber. Specifically, the fan can drive the circulation of gas within the first chamber, or it can deliver gas into or extract gas from the first chamber. The sensor is mounted on the outside of the enclosure. The sensor is used to detect the ambient temperature outside the enclosure, which is typically the outdoor temperature during cold chain transportation.

[0107] During the operation of the refrigeration equipment, when the door assembly is confirmed to be open, the ambient temperature outside the chamber is acquired via sensors. The operating status of the refrigeration components and fans is then controlled based on this ambient temperature. Specifically, if the ambient temperature outside the chamber is low enough to meet freezing or refrigeration requirements, the fan speed is increased, and the refrigeration components are reduced in power or shut down. This airflow generated by the fan accelerates the ventilation efficiency between the inside and outside of the chamber, quickly introducing low-temperature gas from outside. Conversely, if the ambient temperature outside the chamber is high enough to fail to meet freezing or refrigeration requirements, the fan speed is reduced or shut down, and the refrigeration components are increased in power. This reduces the ventilation efficiency between the inside and outside of the chamber, preventing the rapid introduction of high-temperature gas from disrupting the low-temperature environment of the first chamber, while maintaining the low-temperature environment through the high-power operation of the refrigeration components.

[0108] Therefore, this application, by defining the aforementioned control method, can, on the one hand, rationally utilize the low-temperature gas outside the container to refrigerate the interior in low-temperature environments, thereby reducing compressor energy consumption. On the other hand, it can reduce the air exchange efficiency between the inside and outside of the container in high-temperature environments, preventing external high-temperature gas from affecting the freezing or refrigeration effect of goods, and also helps reduce the energy consumption of the refrigeration components to compensate for the inflow of hot air. This solves the technical problems of high energy consumption and poor economic efficiency in cold chain transportation existing in related technologies. Furthermore, it achieves the technical effects of optimizing the structure of refrigeration equipment, reducing energy consumption of refrigeration equipment, and improving the practicality and reliability of refrigeration equipment.

[0109] In any of the above embodiments, controlling the operating state of the cooling components and the fan according to the ambient temperature includes:

[0110] When the ambient temperature matches the target temperature range, turn off the cooling components and control the fan to increase its speed.

[0111] If the ambient temperature does not match the target temperature range, control the fan speed to reduce.

[0112] In this embodiment, the step of controlling the operating state of the cooling components and the fan based on the ambient temperature is described. Specifically, after obtaining the ambient temperature, it is compared with a target temperature range. If the ambient temperature is within the target temperature range, it is determined that the target temperature range matches the ambient temperature. The cooling components are then shut down, and the fan speed is increased. This reduces energy consumption by shutting down the cooling components and makes better use of external cooling capacity by increasing the fan speed. Conversely, if the ambient temperature is outside the target temperature range, it is determined that the target temperature range does not match the ambient temperature. The fan speed is then reduced to decrease the airflow exchange rate between the inside and outside of the enclosure, preventing rapid loss of internal cooling capacity.

[0113] Specifically, the target temperature range can be an open range containing only the maximum temperature or a closed range. For example, when refrigeration equipment needs to refrigerate materials, the target temperature range is a closed range. If the ambient temperature is higher than the maximum temperature, the internal cooling loss needs to be reduced by decreasing the internal and external air exchange rates. If the ambient temperature is lower than the maximum temperature, the internal and external air exchange rates need to be reduced to prevent the temperature of the first chamber from becoming too low and to prevent the refrigerated materials from freezing. This achieves the technical effects of rationally utilizing external cooling capacity, improving the refrigeration reliability of the equipment, and reducing the energy consumption of the refrigeration equipment.

[0114] In any of the above embodiments, before the step of controlling the operating state of the refrigeration component and the fan according to the ambient temperature, the control method further includes:

[0115] Determine the target temperature range based on the operating mode of the refrigeration equipment.

[0116] In this embodiment, before controlling the working state of the refrigeration components and the fan according to the ambient temperature, the target temperature range is first determined according to the working mode of the refrigeration equipment. Different working modes correspond to different target temperature ranges, thereby ensuring that the refrigeration equipment makes reasonable use of the cooling capacity of the external environment and avoiding adverse effects of external air on the refrigeration process.

[0117] Specifically, the refrigeration equipment includes two operating modes: refrigeration mode and freezing mode. A first set temperature is pre-stored for refrigeration mode, and a second set temperature is set for freezing mode. When the current operating mode is determined to be refrigeration mode, the corresponding first target temperature range is greater than or equal to -1℃ and less than or equal to (A+2)℃, where A is the first set temperature, which is taken from the nationally stipulated refrigeration temperature range. When the current operating mode is determined to be freezing mode, the corresponding second target temperature range is greater than or equal to (B-5)℃ and less than or equal to (B+2)℃, where B is the second set temperature, which is taken from the nationally stipulated freezing temperature range.

[0118] like Figure 6As shown, a fourth aspect of this application provides a control device 600 for a refrigeration device, used to control the refrigeration device as described in any of the above embodiments. The control device 600 for the refrigeration device includes:

[0119] The acquisition module 602 is used to acquire the ambient temperature outside the enclosure based on the fact that the enclosure door assembly is in the open state;

[0120] The control module 604 is used to control the operating status of the refrigeration components and the fan according to the ambient temperature.

[0121] In this embodiment, a control device is defined for controlling the operation of the refrigeration equipment in any of the above embodiments.

[0122] The refrigeration equipment includes a housing, a door assembly, and a refrigeration unit. The housing is the main frame structure of the refrigeration equipment, and a first cavity for storing materials is enclosed inside the housing. An opening is provided on the cavity to connect with the first cavity, through which materials are stored in or taken out of the first cavity.

[0123] The door assembly is installed at the opening on the container body. The door assembly can open or close the opening. During transportation, the door assembly is in the closed state, and when loading and unloading goods, the door assembly is in the open state.

[0124] The refrigeration unit is installed on the cabinet. The refrigeration unit can cool the first cavity through the refrigerant heat exchange principle to maintain the low temperature environment in the first cavity and meet the low temperature refrigeration or low temperature freezing requirements of materials.

[0125] In addition, the refrigeration equipment also includes a fan and sensors. The fan is mounted on the enclosure. When turned on, the fan generates airflow within the first chamber. Specifically, the fan can drive the circulation of gas within the first chamber, or it can deliver gas into or extract gas from the first chamber. The sensor is mounted on the outside of the enclosure. The sensor is used to detect the ambient temperature outside the enclosure, which is typically the outdoor temperature during cold chain transportation.

[0126] The control device 600 of the refrigeration equipment includes an acquisition module 602 and a control module 604. When the acquisition module 602 determines that the door assembly is open, it acquires the ambient temperature outside the chamber through a sensor. Subsequently, the control module 604 controls the operating status of the refrigeration components and the fan based on the ambient temperature. Specifically, when the ambient temperature outside the chamber is determined to be low enough to meet freezing or refrigeration requirements, the fan speed is increased, and the refrigeration components are controlled to reduce power or shut down. This accelerates the airflow between the inside and outside of the chamber, rapidly introducing low-temperature gas from outside. When the ambient temperature outside the chamber is determined to be high enough to not meet freezing or refrigeration requirements, the fan speed is reduced or shut down, and the refrigeration components are controlled to increase power. This reduces the airflow efficiency between the inside and outside of the chamber, preventing the rapid introduction of high-temperature gas from damaging the low-temperature environment of the first cavity, while maintaining the low-temperature environment through the high-power operation of the refrigeration components.

[0127] Therefore, this application, by defining the control device 600 of the aforementioned refrigeration equipment, can, on the one hand, rationally utilize the low-temperature gas outside the container to refrigerate the interior in low-temperature environments, thereby reducing the energy consumption of the compressor. On the other hand, it can reduce the air exchange efficiency between the inside and outside of the container in high-temperature environments, preventing the high-temperature external gas from affecting the freezing or refrigeration effect of goods, and also helps to reduce the energy consumption of the refrigeration components to compensate for the inflow of hot air. This solves the technical problems of high energy consumption and poor economic efficiency in cold chain transportation existing in related technologies. Furthermore, it achieves the technical effects of optimizing the structure of refrigeration equipment, reducing its energy consumption, and improving its practicality and reliability.
