Description

Technical Field

[0001] This invention relates to a cold storage facility, specifically a high-efficiency, energy-saving, mobile energy storage cold storage facility. Background Technology

[0002] Cold storage facilities are primarily used for the constant-temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, frozen drinks, flowers, green plants, tea, pharmaceuticals, chemical raw materials, electronic instruments, and more. A cold storage facility is essentially a low-temperature refrigeration system; it is a type of refrigeration equipment. Compared to refrigerators, cold storage facilities have a much larger refrigeration area, but they share the same refrigeration principles.

[0003] Most cold storage facilities currently available are large, fixed structures that cannot be moved. For places that require temporary or short-term freezing, purchasing large cold storage equipment is too expensive, while small insulated boxes or refrigerators are either too small to fit or require multiple units to be used together, which also greatly increases the operating costs.

[0004] Chinese Patent Application No. CN201710382404.5 discloses a mobile cold storage unit, including a box body. Fixed boxes are fixedly connected to both sides of the bottom of the box body. A first sliding groove is formed on the top left side of the inner wall of the fixed box. A first sliding rod is slidably connected inside the first sliding groove. A first fixing block is fixedly connected to the bottom of the first sliding rod. A first movable rod is movably connected to the front of the first fixing block. This invention achieves the effect of easy movement of the cold storage unit by using a combination of fixed boxes, a first sliding groove, a first sliding rod, a first movable rod, a second movable rod, a first connecting block, an electric telescopic rod, a second connecting block, a first roller, a second sliding groove, a partition, a roller groove, a second sliding rod, a spring, a bracket, and a second roller. This solves the problem of existing cold storage units being fixed in location and inconvenient to move, thus increasing the practicality of the cold storage unit.

[0005] In reality, mobile cold storage units are often moved and placed outdoors. In summer or when exposed to sunlight, the outside air temperature is high. Every time the user opens the cold storage door, cold air leaks out, causing the temperature inside the cold storage to rise. To maintain a low-temperature environment inside the cold storage, the refrigeration equipment must be activated every time the door is opened and cold air leaks out. This increases the power required for freezing inside the cold storage, resulting in high energy consumption for mobile cold storage units, which needs improvement. Summary of the Invention

[0006] Based on the above description, the present invention provides a high-efficiency and energy-saving mobile energy storage cold storage to solve the problem of high energy consumption caused by the need to frequently start refrigeration after opening and closing the door in existing mobile cold storage.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0008] A high-efficiency, energy-saving mobile cold storage unit includes a freezer compartment and a cold storage compartment that are interconnected. An insulated inner door separates the freezer compartment and the cold storage compartment. An insulated outer door is installed on the side wall of the cold storage compartment. An air outlet is installed inside the freezer compartment. Refrigeration equipment is installed on the outer wall of the freezer compartment and connected to the air outlet. An inner cold storage module is installed on the inner wall of the freezer compartment, and an outer cold storage module is installed on the inner wall of the cold storage compartment. A first temperature sensor for detecting the indoor temperature is installed inside the freezer compartment, and a second temperature sensor for detecting the indoor temperature is installed in the cold storage compartment. A ventilation opening is provided on the inner door, and a blower is installed at the ventilation opening to deliver cold air from the freezer compartment to the cold storage compartment. A movable cover is also provided at the ventilation opening to cover the ventilation opening and control its opening degree. The cover is driven by an electric push rod. The mobile cold storage unit also includes a controller for controlling the refrigeration equipment, the blower, and the electric push rod. The first and second temperature sensors are connected to the controller.

[0009] As a preferred embodiment: When the cold storage starts operating, the controller controls the refrigeration equipment. The first temperature sensor detects the temperature inside the freezer compartment in real time and feeds the temperature signal back to the controller. The controller compares the collected temperature value with a first preset temperature value. When the collected temperature value reaches the first preset temperature, the controller controls the refrigeration equipment to stop operating. After the temperature inside the freezer compartment reaches the first preset temperature, the controller drives the cover plate down via the electric push rod, at which point the vent is opened. At the same time, the controller controls the blower to start, and the blower begins to deliver cold air from the freezer compartment to the cold storage compartment. During this process, the second temperature sensor detects the temperature inside the cold storage compartment in real time and feeds the detected temperature back to the controller. When the temperature inside the cold storage compartment reaches the second preset temperature, the controller controls the electric push rod to drive the cover plate back to its original position, thereby completely covering the vent. At the same time, the controller controls the blower to stop operating. The second preset temperature is higher than the first preset temperature, and the area of ​​the inner cold storage module is larger than the area of ​​the outer cold storage module.

[0010] As a preferred embodiment: the cold storage is equipped with a third temperature sensor for detecting ambient temperature, and an infrared sensor for detecting human body is installed above the outer door. The temperature sensor and the infrared sensor are connected to the controller. After the infrared sensor detects a human body, the controller collects the ambient temperature detected by the third temperature sensor and retrieves the control parameters of the electric push rod and the blower according to the current ambient temperature. The controller then controls the extension and retraction of the electric push rod and the speed of the blower according to the control parameters.

[0011] As a preferred embodiment: A radar module for detecting the number of people is installed above the outer door. The radar is connected to a controller. The detection range of the radar module is greater than that of the infrared sensor. When the infrared sensor detects that a person is approaching, the controller retrieves the corresponding correction coefficient based on the number of people detected by the radar module and retrieves the control parameters based on the ambient temperature. The controller then multiplies the control parameters with the correction coefficient to obtain the corrected control parameters. The controller adjusts the extension and retraction of the electric push rod and the speed of the blower based on the corrected control parameters.

[0012] As a preferred embodiment, the main body of the electric actuator is covered with a protective cover to protect the electric actuator.

[0013] As a preferred embodiment: the cover plate includes a hollow plate body, and the plate body is filled with heat-insulating filler to give the plate body good heat insulation performance, and a sealing gasket is fixed on the side of the plate body facing the inner door, which can ensure a good seal between the plate body and the ventilation opening.

[0014] As a preferred option, the walls of this mobile energy storage cold storage are multi-layered composite structures, consisting of an outer shell, a cavitation layer, an insulation layer, and a heat-reflective layer from the outside in. This multi-layered composite structure gives the walls excellent thermal insulation performance and reduces heat loss from the cold storage.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The mobile energy storage cold storage in this application has the transition function of the cold storage chamber and the balancing function of the cold storage module. Moreover, the heat exchange between the freezing chamber and the cold storage chamber is only through a small ventilation opening. Not only is the heat exchange area significantly reduced, but the temperature difference during heat exchange is also significantly reduced. Therefore, the temperature in the freezing chamber will not fluctuate significantly during the process of entering and leaving the cold storage. This can effectively reduce the number of times the refrigeration equipment is put into operation and achieve the purpose of energy saving. Attached Figure Description

[0024] Reference Figure 1 A high-efficiency and energy-saving mobile cold storage includes a freezer compartment 1 and a cold storage compartment 2 that are interconnected. An insulated inner door 5 is provided between the freezer compartment 1 and the cold storage compartment 2. When the inner door 5 is closed, it separates the freezer compartment 1 and the cold storage compartment 2, making them independent chambers. An insulated outer door 6 is installed on the side wall of the cold storage compartment 2. When the outer door 6 is closed, it can isolate the cold storage compartment 2 from the outside air.

[0025] After opening the outer door 6, one can enter the cold storage room 2 from outside the warehouse. After opening the inner door 5, one can enter the freezer room 1 from the cold storage room 2.

[0026] An air outlet device 4 is installed inside the freezer compartment 1, and a refrigeration device 3 is installed on the outer wall of the freezer compartment 1. The refrigeration device 3 is connected to the air outlet device 4. After the refrigeration device is started, cold air is delivered into the freezer compartment 1 through the air outlet device 4.

[0027] Multiple sets of internal cold storage modules 7 are installed on the inner wall of the freezer compartment 1, and multiple sets of external cold storage modules 8 are installed on the inner wall of the cold storage compartment 2. A first temperature sensor 9 for detecting the indoor temperature is installed inside the freezer compartment 1; a second temperature sensor 10 for detecting the indoor temperature is installed inside the cold storage compartment 2; and a third temperature sensor 19 for detecting the ambient temperature is installed outside the cold storage.

[0028] Reference Figure 1 and Figure 2A ventilation opening 11 is provided on the inner door 5, and a blower 12 is installed at the ventilation opening 11 to transport cold air from the freezer compartment 1 to the cold storage compartment 2. A movable cover 14 is also provided at the ventilation opening 11 to cover the ventilation opening 11 and control the opening degree of the ventilation opening 11. An electric push rod 13 is provided below the cover 14. The main body of the electric push rod 13 is connected and fixed to the inner door 5, and the upper end of the rod 13 is connected and fixed to the lower part of the cover 14. By controlling the extension and retraction of the electric push rod 13, the cover 14 can be moved up and down, thereby controlling the opening degree of the ventilation opening 11.

[0029] Reference Figure 6 The mobile energy storage cold storage also includes a controller, which includes a main control module, a relay for controlling the start and stop of the refrigeration unit, a fan drive module for driving the blower 12, an electric drive module for driving the electric push rod 13, a communication module for communicating between the controller and external devices, and a power supply module for supplying power to the controller.

[0030] The signal input terminal of the drive board is connected to the control signal output terminal of the main control module; the coil of the relay is connected to the control signal output terminal of the main control module; and the switch contacts of the relay are connected to the power circuit of the refrigeration unit. The input terminal of the fan drive module is connected to the control signal output terminal of the main control module, and the output terminal of the fan drive module is connected to the fan. The input terminal of the electric drive module is connected to the control signal output terminal of the main control module, and the output terminal of the electric drive module is connected to the electric push rod 13. The communication module is connected to the communication port of the main control module. The first temperature sensor 9, the second temperature sensor 10, and the third temperature sensor 19 are connected to the signal sampling terminal of the main control module. The power supply module is connected to the power supply terminals of each module for power supply.

[0031] The working principle of this mobile energy storage cold storage is as follows: In the initial state, the cover plate 14 completely covers the ventilation opening 11, and both the inner door 5 and the outer door 6 are closed. When the cold storage starts running, the main control module controls the relay to connect the power supply to the refrigeration equipment 3. At this time, the refrigeration equipment 3 is put into operation, and the cold air generated by the refrigeration equipment 3 enters the freezer compartment 1 through the air outlet 4, causing the freezer compartment 1 to start cooling down. During this process, the first temperature sensor 9 detects the temperature in the freezer compartment 1 in real time and feeds the temperature signal back to the main control module. The main control module compares the collected temperature value with the first preset temperature value. When the collected temperature value reaches the first preset temperature, the main control module controls the refrigeration equipment 3 to power off and stop. When the temperature value in the freezer compartment 1 rises, the main control module controls the refrigeration equipment 3 to start running again, thus stabilizing the temperature in the freezer compartment 1.

[0032] After the temperature inside the freezer compartment 1 reaches the first preset temperature, the internal cold storage module 7 reaches the optimal cold storage state.

[0033] After the temperature in the freezer compartment 1 reaches the first preset temperature, the main control module sends a control signal to the electric push drive module to retract the electric push rod 13, thereby driving the cover plate 14 to descend. At this time, the vent 11 is opened. At the same time, the main control module sends a control signal to the fan drive module to start the blower 12. The blower 12 begins to transport the cold air in the freezer compartment 1 to the cold storage compartment 2. During this process, the second temperature sensor 10 detects the temperature in the cold storage compartment 2 in real time and feeds back the detected temperature to the main control module. When the temperature in the cold storage compartment 2 reaches the second preset temperature, the main control module controls the electric push rod 13 to drive the cover plate 14 to reset, thereby completely covering the vent 11. At the same time, the main control module controls the blower 12 to stop running. At this time, the external cold storage module 8 reaches the optimal cold storage state.

[0034] In this embodiment, the second preset temperature is higher than the first preset temperature, and the area of ​​the inner cold storage module 7 is larger than the area of ​​the outer cold storage module 8.

[0035] When a user needs to enter the cold storage, they first open the outer door 6 to enter the cold storage chamber 2 and then close the outer door 6. During the opening and closing of the outer door 6, the cold air in the cold storage chamber 2 will dissipate to the outside. The outer cold storage module 8 absorbs the heat entering the cold storage chamber 2, so that the temperature inside the cold storage chamber 2 will not rise too much after the outer door 6 is closed. Then, the user opens the inner door 5 to enter the freezer chamber 1 and closes the inner door 5. Since the temperature inside the cold storage chamber 2 is higher than the temperature inside the freezer chamber 1, the heat inside the cold storage chamber 2 will enter the freezer chamber 1 during the opening and closing of the inner door 5. Since the area of ​​the inner cold storage module 7 is larger than that of the outer cold storage module 8 and the temperature of the inner cold storage module 7 is lower, the inner cold storage module 7 can absorb heat more effectively, so that the temperature inside the freezer chamber 1 will not fluctuate significantly, reducing the number of times the refrigeration equipment 3 is put into operation, thus achieving the purpose of saving energy.

[0036] When the user leaves the cold storage, both the internal cold storage module 7 and the external cold storage module 8 can still absorb heat.

[0037] Traditional mobile cold storage facilities only have one door. Every time the door is opened and closed, the heat exchange area between the inside of the cold storage and the outside environment is very large, which causes a large amount of cold air to escape and the temperature inside the cold storage to rise significantly. Basically, the refrigeration equipment needs to be restarted after each opening and closing of the door, which consumes a lot of electricity.

[0038] The mobile energy storage cold storage in this application has the transitional function of the cold storage chamber 2 and the balancing function of the cold storage module. Moreover, the heat exchange between the freezer chamber 1 and the cold storage chamber 2 is only through a small ventilation opening 11. Not only is the heat exchange area significantly reduced, but the temperature difference during heat exchange is also significantly reduced. Therefore, the temperature in the freezer chamber 1 will not fluctuate significantly during the process of entering and leaving the cold storage, which can effectively reduce the number of times the refrigeration equipment 3 is put into operation and achieve the purpose of energy saving.

[0039] In addition, since the temperature inside the cold storage chamber 2 is higher than that inside the freezer chamber 1, the temperature difference between the cold storage chamber 2 and the outside is smaller. Furthermore, due to the balancing effect of the external cold storage module 8, the rate of heat exchange between the cold storage chamber 2 and the outside is low during the opening and closing of the outer door 6, and the temperature fluctuation inside the cold storage chamber 2 will not be too large. Moreover, the volume of the freezer chamber 1 is much larger than that of the cold storage chamber 2, so there is no need for the freezer chamber 1 to supplement a large amount of cold air into the cold storage chamber 2. Supplementing a small amount of cold air into the cold storage chamber 2 will not cause significant temperature fluctuations in the freezer chamber 1. The overall energy-saving effect of this mobile energy storage cold storage is very significant.

[0040] Considering that when the ambient temperature is high, the heat exchange between the cold storage chamber 2 and the outside will increase, in order to prevent the temperature inside the cold storage chamber 2 from rising too much after the outer door 6 is opened, additional cold air can be supplied to the cold storage chamber 2 in advance to make the temperature inside the cold storage chamber 2 slightly lower than the second preset value. This will ensure that the temperature inside the cold storage chamber 2 will not rise too much after the heat exchange between the cold storage chamber 2 and the outside is completed.

[0041] To achieve the above objectives, after the temperature of the cold storage chamber 2 reaches the second preset temperature, the opening and closing of the outer door 6 is tested under different ambient temperatures. After the temperature inside the cold storage chamber 2 rises due to the opening and closing of the door, the blower 12 is controlled to deliver cold air to the cold storage chamber 2, ensuring that the temperature of the cold storage chamber 2 returns to the second preset temperature after 5 seconds. The amount of cold air supplied to the cold storage chamber 2 during this process is the required additional cold air. The additional cold air can be quantified by the rotation speed of the blower 12 and the opening degree of the cover 14 (in this embodiment, the running time of the blower 12 is fixed, such as 5 seconds).

[0042] The above operations can obtain the opening degree of the cover plate 14 (corresponding to the extension and retraction of the electric push rod 13) and the speed of the blower 12 (corresponding to the gear of the blower 12) required when additional cooling is added under different ambient temperatures. In this way, control parameters for additional cooling when adding cooling under various ambient temperatures can be established, and the ambient temperature and the corresponding control parameters can be stored in the main control module.

[0043] Reference Figure 3 Above the outer door 6 is an infrared sensor 18 for detecting the approach of a person. The infrared sensor 18 is connected to the signal sampling terminal of the main control module. When a person enters the detection range of the infrared sensor 18, the infrared sensor 18 sends a detection signal back to the main control module. At this time, the main control module collects the signal from the third temperature sensor 19 to obtain the ambient temperature, and retrieves the corresponding control parameters from memory based on the ambient temperature. According to the control parameters, it controls the cover 14 to open to the required degree and controls the fan 12 to run at the required speed. After 5 seconds, it controls the cover 14 to close and controls the fan 12 to stop, thus automatically completing the operation of replenishing additional cold air. After 5 seconds, the user arrives at the outer door 6 and can open the outer door 6.

[0044] Based on this, considering that the number of people entering the cold storage can be one, two, or more, the time required to open and close the outer door 6 is longer when two or more people enter the cold storage compartment 2. Essentially, the more people there are, the longer the time, which means that the heat exchange is greater when there are more people during the opening and closing of the outer door 6. To avoid large temperature fluctuations in the cold storage compartment 2 when multiple people enter, the amount of additional cold air needed must also take into account the number of people.

[0045] Reference Figure 1 and Figure 3 In this embodiment, a radar module 17 is installed above the outer door 6. The radar module 17 is connected to the main control module and is used to detect the number of people approaching. When a person enters the detection range of the radar module 17, the radar module 17 identifies the number of targets and feeds back the identification result to the main control module. The main control module has a correction coefficient preset for different numbers of people. For example, the correction coefficient is 1 when there is 1 person, the correction coefficient is greater than 1 when there are 2 people, the correction coefficient is even greater when there are 3 people, and so on.

[0046] The radar's detection range is greater than that of the infrared sensor 18. When the infrared sensor 18 detects people approaching, the main control module retrieves a correction coefficient based on the number of people detected by the radar module 17 and retrieves control parameters based on the ambient temperature. The main control module then multiplies the control parameters by the correction coefficient to obtain the corrected control parameters, and controls the opening of the cover 14 and the rotation speed of the blower 12 based on the corrected control parameters. This allows for dynamic adjustment of the additional cooling air supply based on the number of people.

[0047] Reference Figure 1 In this embodiment, a protective cover 15 is also provided on the outside of the main body of the electric push rod 13 to protect the electric push rod 13.

[0048] Reference Figure 4 In this embodiment, the cover plate 14 includes a hollow plate 1401, and a heat-insulating filler 1403 is installed inside the plate 1401 to give the plate 1401 good heat insulation performance. A sealing gasket 1402 is fixed on the side of the plate 1401 facing the inner door 5. The sealing gasket 1402 can ensure a good seal between the plate 1401 and the vent 11 to prevent air leakage.

[0049] Reference Figure 5 In this embodiment, the wall of the mobile energy storage cold storage is a multi-layer composite structure, which includes an outer shell 101, a cavitation layer 102, a heat insulation layer 103 and a heat reflective layer 104 from the outside to the inside. The multi-layer composite structure gives the wall good thermal insulation performance and reduces the heat loss of the cold storage to the outside.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
