[0002] In a low-temperature cold storage, especially a high-rise three-dimensional cold storage, due to its height, it is difficult to make the temperature of each height position area inside the cold storage uniform during the temperature adjustment process inside the cold storage. At the same time, when the temperature of a certain height area in the cold storage is lower than the preset threshold, it is generally not easy to adjust, and the turbulence adjustment method is relatively slow for temperature adjustment. Summary of the invention

[0007] After the refrigeration is completed, second temperature data at different height positions inside the refrigeration space are obtained;

[0008] The working state of the spoiler is adjusted according to the second temperature data.

[0009] In one embodiment, the step of adjusting the temperature inside the refrigeration space according to the first temperature data and simultaneously performing a turbulence operation during the adjustment process further includes:

[0010] Calculating an average temperature value of the first temperature data obtained;

[0016] When the first temperature data is not within the disturbance temperature threshold, triggering a disturbance operation;

[0017] When the second temperature data are all within the disturbance temperature threshold range, the disturbance operation is forcibly started.

[0018] In one embodiment, when the first temperature data is not within the disturbance temperature threshold, triggering the disturbance operation further includes:

[0019] When some of the first temperature data are not within the disturbance temperature threshold, and some of the first temperature data are higher than the upper limit of the disturbance temperature threshold, and the rest of the first temperature data are within the range of the disturbance temperature threshold, return air operation and air supply operation are performed for all other height areas;

[0020] When any of the first temperature data is lower than the lower limit of the turbulence temperature threshold, and the rest of the first temperature data are within the range of the turbulence temperature threshold, the air supply operation of the temperature area below the lower limit of the turbulence temperature threshold is stopped, the return air operation of the height area is maintained, and the air supply operation and the return air operation are performed in the rest of the height areas within the range of the turbulence temperature threshold;

[0038] Embodiment 1

[0039] See also Figure 1 The cold storage temperature adjustment method provided by the present invention comprises the following steps:

[0040] S1, obtaining real-time first temperature data at different height positions of the refrigeration space.

[0041] It can be understood that the temperature sensors are arranged at different heights in the refrigeration space, and the distances between the temperature sensors at adjacent positions may be consistent.

[0042] S2, adjusting the temperature inside the refrigeration space according to the first temperature data, and performing a turbulence operation during the adjustment process;

[0043] The above steps may further include:

[0044] S201, calculating the average temperature value inside the refrigeration space using the acquired temperature data.

[0045] S202: When the average temperature value is greater than the average temperature threshold, the temperature inside the refrigeration space is adjusted and a turbulence operation is performed at the same time.

[0046] It can be understood that the average temperature threshold can be (-18°C, -20°C). When the average temperature is higher than -18°C, the refrigeration operation will be performed. During the refrigeration process, when the average temperature reaches -20°C, the refrigeration work will stop. After stopping for a period of time, the temperature will gradually rise. During the average temperature rising process, the refrigeration will not work. When the average temperature is higher than -18°C, the above refrigeration process will be repeated. Refrigeration operation refers to the refrigeration mechanism in the working state. The turbulence operation can include air supply and return air. When the air supply and return air are working, they are in a turbulence state. There are two ways of air supply operation. One is to make When the cooling mechanism is in working state, the cooling capacity generated by the cooling mechanism is transported. The other state is when the cooling mechanism is not working. In the cooling working state, both the air supply operation and the return air operation need to be kept in working state. In the cooling state, the cooling mechanism is located at the upper part, and the air supply is to transport the cooling capacity generated by the refrigeration mechanism from the upper part to the lower part of the cooling space at various height positions. In the non-cooling state, the air supply operation is to transport the air from the upper part to the lower space, and the return air is to transport the air from the bottom to the upper space. During the cooling process, the air supply and return air operations can be triggered operations, and when they are not within the triggering conditions, they can be forced to start operations.

[0047] The above-mentioned spoiler temperature threshold may be (-16°C, -22°C), and the first temperature data may have the following conditions:

[0048] 1. The first temperature data has data higher than the upper limit of the spoiler temperature threshold of -16°C, and the other first temperature data are within the spoiler temperature threshold range;

[0049] 2. The existence value of the first temperature data is lower than the lower limit of the spoiler temperature threshold value -22°C, and the other first temperature data are within the range of the spoiler temperature threshold value;

[0050] 3. There is a situation where the temperature value of the first temperature data is higher than the upper limit -16°C, and the temperature values ​​of the remaining first temperature data are lower than the lower limit -22°C of the spoiler temperature threshold;

[0051] 4. All first temperature data are within the spoiler temperature threshold range.

[0052] For the first three cases mentioned above, that is, the first temperature data is not within the turbulence temperature threshold range, in this case, the air supply and return air will be triggered to work. For the fourth case, forced air supply and return air need to work.

[0053] For the first three cases, the working status of the supply and return air operations can be:

[0054] For case 1, the air supply state is: for a height position higher than the upper limit of the turbulence temperature threshold of -16°C, the height position will be in the air supply state, and other height areas will also be in the air supply state if the temperature value does not reach the lower limit of the turbulence temperature threshold of -22°C. When it is lower than the lower limit of the turbulence temperature threshold of -22°C, the air supply state of the height area will be turned off. When the air is supplied, the closer the first temperature data is to the lower limit of the turbulence temperature threshold of -22°C, the air supply volume of the height area will gradually decrease until the first temperature data of the height area is not greater than -22°C. When the first temperature data is less than -22°C, the air supply is stopped;

[0055] The return air state is: in this case, at a height position higher than -16°C, it will be in a full return air state, that is, the state of maximum return air volume, until the first temperature data of the height area is no greater than -22°C. When the first temperature data is closer to the lower limit of the turbulence temperature threshold -22°C, the return air volume of the height area will gradually decrease until the return air is completely stopped;

[0056] For case 2, the air supply status is: in the altitude area below the lower limit of the turbulence temperature threshold of -22°C, the air supply in this altitude area is completely stopped, while other altitude areas will also supply air until the temperature in this altitude area is no more than -22°C, and as the altitude area gets closer to -22°C, the air supply volume gradually decreases;

[0057] The return air status is: in this case, as long as the first data is not at the temperature value of -22°C, the lower limit of the turbulence temperature threshold, each height area needs to perform return air operation. For the height area corresponding to a temperature lower than 22°C, the return air volume can be appropriately reduced. The greater the absolute value of the difference between the first temperature data of each height area and the lower limit of the turbulence temperature threshold -22°C, the greater the return air volume. Otherwise, the return air volume will decrease until the temperature of the height area is at -22°C.

[0058] For situation three, the air supply state is: at a height position higher than the upper limit of the spoiler temperature threshold of -16°C, the height position will be in the air supply state, and other height areas will also be in the air supply state if the temperature value does not reach the lower limit of the spoiler temperature threshold of -22°C. When it is lower than the lower limit of the spoiler temperature threshold of -22°C, the air supply state of the height area will be turned off. When the air is supplied, the closer the first temperature data is to the lower limit of the spoiler temperature threshold of -22°C, the air supply volume of the height area will gradually decrease until the first temperature data of the height area is no greater than -22°C. For the height area below the lower limit of the spoiler temperature threshold of -22°C, the air supply is completely stopped;

[0059] The return air status is that as long as the first data is not at the lower limit of the turbulence temperature threshold of -22°C, each height zone needs to perform return air operation. The greater the absolute value of the difference between the first temperature data of each height zone and the lower limit of the turbulence temperature threshold of -22°C, the greater the return air volume. Otherwise, the return air volume will decrease until the temperature of the height zone is at -22°C.

[0060] For situation four, the first temperature data are all within the turbulence temperature threshold range, and will not actively trigger the supply and return air operations. However, in the cooling state, the supply and return air operations need to be forced to start. In this case, as long as the height area has not reached the lower limit of the turbulence temperature threshold of -22°C, it is in the supply air state. When supplying air, the closer the first temperature data is to the lower limit of the turbulence temperature threshold of -22°C, the supply air volume of this height area will gradually decrease until the first temperature data of this height area is not greater than -22°C. Similarly, as long as the first temperature data does not reach the height area of ​​the lower limit of the turbulence temperature threshold of -22°C, the return air is also in a forced working state until the first temperature data of this height area is not greater than -22°C. The greater the absolute value of the difference between the first temperature data of each height area and the lower limit of the turbulence temperature threshold of -22°C, the greater the return air volume. Otherwise, the return air volume will decrease accordingly.

[0061] S3, after the refrigeration is completed, obtaining second temperature data at different height positions inside the refrigeration space.

[0062] It is understandable that the above steps may further include:

[0063] S301, when the average temperature inside the refrigeration space is not greater than the average temperature threshold, end the refrigeration.

[0064] It is understandable that when the average temperature reaches -20°C, the refrigeration work ends, that is, the refrigeration mechanism stops working. In this case, the status of return air and supply air needs to be judged based on the second temperature data collected subsequently.

[0065] S302: Acquire second temperature data at different height positions inside the refrigeration space.

[0066] It is understandable that whether the turbulence operation should be stopped will be judged only after the refrigeration is completed, because before the refrigeration is completed, the supply air and return air will be in a forced working state. After the refrigeration is completed, the supply air and return air states will be readjusted according to the second temperature data.

[0067] S4, adjusting the working state of the spoiler according to the second temperature data.

[0068] The above steps may further include:

[0069] S401: When the second temperature data is not within the spoiler temperature threshold, keep the spoiler working.

[0070] It can be understood that when the cooling is finished, the temperature of each height zone is within the turbulence temperature threshold. In this case, the supply air and return air can be in a stopped state. There are also cases where the temperature data of some height zones are not within the turbulence temperature threshold. In this case, the return air and blowing operations refer to the above description.

[0071] Embodiment 2

[0072] See also Figure 2 The cold storage temperature regulating device provided in this embodiment includes at least two regulating components in opposite positions, and the working states of the two regulating components are different. The regulating components include an air supply component 2 and a return air component 1. The air supply component 2 is used to transport cold air to different height positions in the refrigeration space. The return air component 1 is assembled on the air supply component 2 and is used to cooperate in performing turbulence operations when the air supply component 2 of the regulating component at the relative position is in the working state.

[0073] It can be known that the regulating device is mainly used in high-rise stereoscopic cold storage. The air supply component 2 can be bonded to the inner wall position in the height direction of the high-rise stereoscopic cold storage, or it can be connected and fixed by means of clamps or bolts. The interior of the high-rise stereoscopic cold storage can be divided into several areas. The regulating device in one area can include two regulating components. The two regulating components are relatively located, which can be understood as a symmetrical arrangement. The two regulating components are close to each other. The different working states of the two regulating components can be understood as the air supply component 2 of one of the regulating components is in a working state, and its return air component 1 is in a non-working state, and the air supply component 2 of the other regulating component is in a non-working state, and its return air component 1 is in a working state. The air supply component 2 in a working state can include two forms, one is that the refrigeration structure works at the same time, and the other is that the refrigeration structure does not work. The working state can refer to the description of the above embodiment one.

[0074] See also Figure 2 In some embodiments, the return air component 1 includes a return air duct and a return air fan 101 , the return air fan 101 is installed on the upper part of the return air duct, and the air supply component 2 is connected to the return air duct 1 .

[0075] It can be understood that the return air duct can be arranged along the height direction of the high-rise stereoscopic cold storage, and it can also be used as a partial component of the air supply component 2. The return air fan 101 draws the bottom air into the return air duct, and enters the top of the high-rise stereoscopic cold storage through the upper part of the return air duct, thereby cooperating with the air supply component to achieve the effect of turbulence.

[0076] Please continue reading Figure 2In some embodiments, the return air duct includes a tube body 103, a first electric air valve 102 and several electric proportional valves 104. The tube body 103 is provided with several openings at different heights. The electric proportional valves 104 are installed at corresponding opening positions. The first electric air valve 102 is installed on the tube body 103 near the return air fan 101.

[0077] It can be known that the spacing between adjacent openings can be consistent, of course, it can also be set to an inconsistent state according to actual needs. The bottom of the tube body 103 can be closed, and the tube body 103 can be semicircular and oblate, so that it is convenient to fit on the wall of the cold storage. Of course, it can also be cylindrical or polygonal. The electric proportional valve 104 can accurately adjust the air outlet size of the opening, so as to adjust and control the air intake or outlet. The electric proportional valve 104 can adjust the return air state of the corresponding height area accordingly, and the return air state adjustment can include return air volume adjustment and opening and closing.

[0078] See also Figure 3 In some embodiments, the tube body 103 includes an inner wall layer 103b, an outer wall layer 103c and a thermal insulation layer 103a, and the thermal insulation layer 103a is located between the inner wall layer 103b and the outer wall layer 103c.

[0079] It can be known that the inner wall layer 103b can be made of rigid material, such as metal or hard plastic material, the outer wall layer 103c can be made of metal material, and the insulation layer 103a can be made of aerogel insulation felt, rubber-plastic insulation material layer or polyurethane foam insulation material layer, etc. The tube body 103 of this structure can reduce the impact of the external environment on the temperature inside the tube body 103, and the air supply pipe structure can also refer to the structural setting of the tube body 103.

[0080] Please continue reading Figure 3 In some embodiments, the return air duct further includes a defrost structure 105 , which is assembled in the duct body 103 .

[0081] It can be known that the defrost structure 105 can be an electric heating pipe or a HDPE pipe in conjunction with a medium delivery pump. The electric heating pipe or the HDPE pipe can be embedded in the insulation layer 103a and close to or attached to the inner wall layer 103b. The HDPE pipe can be arranged around the pipe body 103. The medium delivery pump can deliver hot ethylene glycol solution into the HDPE pipe, thereby defrosting the inner wall surface of the pipe body 103. During the defrost operation, a temperature sensor can be arranged on the inner wall surface of the return air duct to monitor the defrost temperature. During the defrost operation, both the supply and return air operations are in a stopped state. In addition to setting the defrost structure 105 inside the return air duct, a defrost structure 201 can also be set inside the air supply component 2 at the same time. The defrost structure 201 inside the air supply component 2 can refer to the defrost structure 105 in the return air duct.

[0082] See also Figure 2 In some embodiments, the regulating device further includes a water receiving tray 3 , which is assembled at the bottom of the return air component 1 .

[0083] It is understandable that the water generated during the defrosting process can flow into the water receiving tray 3 along the tube body 103 of the return air duct, and can also flow into the water receiving tray 3 along the supply air duct 202 and the tube body 103. The water receiving tray 3 discharges the water generated by defrosting to the outside of the cold storage.

[0084] Please continue reading Figure 4 and Figure 5 In some embodiments, the water receiving tray 3 includes a tray body 301, an electric heating component 302 and a drain pipe 303. The tray body 301 is assembled at the bottom of the return air component 1, the electric heating component 302 is assembled at the bottom side of the tray body 301, and the drain pipe 303 is arranged at the bottom of the tray body 301.

[0085] It can be understood that the disk body 301 can be detachably connected to the tube body 103 of the return air component 1, and the detachable method can be in the form of bolts. The drain pipe 303 can include a stop valve 304. During the defrosting process, the stop valve 304 will be opened, and the drain pipe 303 can be connected to a hose to discharge the water generated by defrosting to the outside of the cold storage. The electric heating component 302 can be an electric heating wire or an electric heating tube, etc., which can heat the bottom of the disk body 301 to avoid frosting or even ice inside the disk body 301. The structure of the disk body 301 can also refer to the setting of the tube body 103, that is, they all have a thermal insulation layer 103a similar to the tube body 103, and the drain pipe 303 can even be covered with some thermal insulation material layers to avoid ice blockage inside the drain pipe 303 due to the internal temperature of the cold storage.

[0086] See also Figure 2 In some embodiments, the air supply component 2 includes an air supply duct 203, an air supply fan 202 and a second electric air valve 204. The air supply duct 203 is connected to the return air component 1, the air supply fan 202 is installed in the air supply duct 203, and the second electric air valve 204 is installed on the air supply duct 203.

[0087] It can be understood that the air supply fan 202 can transport the cold air entering the air supply duct 203 to the bottom of the air supply duct 203, and then the cold air can be discharged from various openings along the tube body 103. The air outlet of the opening can be adjusted by the electric proportional valve 104, thereby achieving temperature regulation at various height positions.

[0088] See also Figure 2 In some embodiments, the air supply component also includes a refrigeration structure, which is assembled in the air supply pipe 203.

[0089] It can be known that the refrigeration structure can be located at the end of the air supply pipe 203, and the refrigeration structure can be a refrigeration terminal evaporator device, which can provide cold air into the air supply pipe 203.

[0090] Embodiment 3

[0091] See also Figure 6 This embodiment provides a high-rise three-dimensional cold storage, including the above-mentioned cold storage temperature regulating device, and also includes a cold storage body, and the return air component 1 is assembled on the inner wall of the cold storage body.

[0092] It can be known that the pipe body 103 of the return air component 1 can be fixed to the inner wall of the cold storage body by a clamp or the like, and an insulation board 4 can also be arranged on the inner wall of the cold storage body. The insulation board 4 is located between the pipe body 103 and the inner wall of the cold storage body, thereby improving the insulation performance of the high-level three-dimensional cold storage.

[0093] From the above description, it can be known that the cold storage temperature adjustment method provided by the present invention can well adjust the temperature of each height area position inside the cold storage, ensure the temperature of each height area position inside the cold storage is uniform, and can also quickly adjust the temperature of a certain height area position.
