Description

Technical Field

[0001] The present invention relates to the technical field of gas-controlled cold storage, and in particular to a vehicle-mounted gas-controlled cold storage, a gas regulating method and a control system. Background Art

[0002] Annual fruit and vegetable losses during transportation and storage in my country account for over 15% of total production, far exceeding the average for developed countries and resulting in significant economic losses. While the cold chain is the most effective means of reducing losses during transportation and storage, my country's cold chain industry faces numerous challenges, particularly the "first kilometer" of the cold chain—pre-cooling fruits and vegetables after harvest—which is particularly critical. While cold chain transportation can only partially mitigate losses, altering the physiological and biochemical reactions of fruits and vegetables through controlled atmosphere (CA) can further improve their quality and reduce losses during transportation and storage.

[0003] In traditional cold storage, because goods need to be stacked and placed, traditional sterilization methods such as ozone and ultraviolet rays have sterilization blind spots and odor transfer, which seriously affects the shelf life of fruits and vegetables. It also causes poor airflow inside the goods, resulting in slow pre-cooling. Even if shelves are used, the interior of a single cargo frame still has problems with poor circulation and slow cooling. Simply lowering the temperature of the refrigeration air will cause chilling damage to fruits and vegetables, seriously affecting their commercial value.

[0004] At the same time, my country's fruit and vegetable production is characterized by a significant sporadic planting pattern. Large-scale cultivation accounts for less than 20% of total output, while smallholder farming accounts for over 80%. Most of these smallholder orchards are located in mountainous areas or remote rural areas, where power systems are unstable and electricity costs are high during long-term operation. Therefore, they typically pre-cool fruits and vegetables using cold water immersion or conventional cold storage. Cold water immersion cooling consumes a lot of water and requires subsequent low-temperature drying, which is time-consuming and labor-intensive. More often, farmers do not pre-cool the fruits and vegetables after harvesting, or transport them to distant locations to sell to consignees. Consignees then centrally pre-cool the fruits and vegetables in large cold storage facilities. This process takes a long time, during which time the fruits and vegetables experience strong respiratory heat production. Long-distance transportation also makes them susceptible to mechanical damage, and subsequent pre-cooling in conventional cold storage facilities is also relatively slow. Furthermore, traditional cold storage facilities are mostly based on civil structures and are immovable, while traditional cold chain vehicles consume a lot of energy and have high maintenance costs. Solar energy is a clean energy. In recent years, with the development of materials science, the efficiency of solar energy conversion has been further improved, and the cost of solar panel materials has been further reduced. Solar power generation has been widely used. Controlled atmosphere cold storage needs to be placed in the fields, which have rich solar energy resources, but solar power generation technology has not yet been applied to controlled atmosphere cold storage.

[0060] First embodiment:

[0061] Regarding the technical problems of slow pre-cooling speed, slow construction of controlled atmosphere environment, sterilization dead corners and storage odor in traditional controlled atmosphere cold storage, please refer to Figure 1 , this embodiment provides a vehicle-mounted atmosphere-controlled cold storage.

[0062] The atmosphere-controlled cold storage includes: an atmosphere-controlled system 2, a battery 3, a high-voltage pulse electric field 5, an air curtain pressure difference refrigeration system 6, a storage body 12, a gas regulation control system 9 and a sensor;

[0063] The air outlet 61 and the air return 62 of the air curtain pressure differential refrigeration system 6 are arranged on both sides of the storage body 12 to perform different modes of air curtain pressure differential refrigeration in the storage body 12 at different gas adjustment stages;

[0064] The atmosphere control system 2 is connected to the interior of the storage body 12 through the atmosphere control circulation loop 7 to perform atmosphere control treatment on the interior of the storage body 12;

[0065] The high-voltage pulse electric field 5 is connected to the gas conditioning system 2 and the interior of the storage body 12 through the gas conditioning circulation loop 7 to sterilize and remove odor from the gas in the storage body 12;

[0066] The battery 3 is arranged outside the storage body 12 to supply power to the electrical system of the gas-controlled cold storage;

[0067] The power system of the atmosphere-controlled cold storage is a system composed of power components of the atmosphere-controlled cold storage.

[0068] The sensor is installed in the storage body to monitor the environment inside the storage body and output the detection data to the gas regulation and control system 9;

[0069] The gas regulating and controlling system 9 is used to control the switching of the cooling mode of the air curtain pressure difference cooling system 6 and the opening of the gas regulating system 2 and the high-voltage pulse electric field 5 according to the detection data.

[0070] The detection data includes: temperature inside the warehouse, concentration of conditioned air in the warehouse and return air temperature;

[0071] The concentration of the gas in the controlled atmosphere includes: oxygen concentration, carbon dioxide concentration and ethylene concentration;

[0072] The preset parameters include: a first preset temperature T1, a second preset temperature T2, a preset concentration and a preset concentration range;

[0073] The preset concentrations include: oxygen preset concentration X0, carbon dioxide preset concentration Y0 and ethylene preset concentration Z0;

[0074] The preset concentration ranges include: an oxygen concentration range X1, a carbon dioxide concentration range Y1, and an ethylene concentration range Z1.

[0075] The gas conditioning circulation loop 7 includes: a first passage 71 and a second passage 72;

[0076] One end of the first passage 71 is connected to the interior of the storage body 12, and the other end is connected to the gas conditioning system 2. One end of the second passage 72 is connected to the gas conditioning system 2, and the other end is connected to the middle position of the first passage 71. A high-voltage pulse electric field 5 is provided on the second passage 72.

[0077] The gas to be conditioned in the storage body 12 enters the conditioning system 2 through the first passage 71 for conditioning, and the conditioned gas enters the storage body 12 through the second passage 72 and the rear end of the first passage 71 in sequence.

[0078] In another embodiment, one end of the second passage 72 is connected to the gas conditioning system 2 , and the other end is connected to the interior of the storage body 12 .

[0079] In another embodiment, since it takes time for the gas conditioning system 2 to adjust the gas concentration, the gas exchange between the storage body 12 and the gas conditioning system 2 is carried out in a time-sharing manner, so the gas conditioning circulation loop may have only one passage. At this time, the gas conditioning control system 9 should reduce the gas conditioning gas flow value obtained by the flow meter 82 by half before comparison.

[0080] The sensors include: a gas detection sensor array 81, an internal temperature sensor and a return air temperature sensor;

[0081] The gas detection sensor array 81 is provided in the storage body 12 and is used to obtain the concentration of the gas in the storage;

[0082] The internal temperature sensor is located in the storage body 12 and is used to obtain the internal temperature;

[0083] The controlled atmosphere cold storage also includes a flow meter 82, which is located on the communication path between the controlled atmosphere system 2 and the interior of the storage body 12. The flow meter 82 is connected to the gas regulation and control system 9 and is used to monitor the flow rate of the controlled atmosphere gas transmitted unidirectionally between the controlled atmosphere system 2 and the storage body. Unidirectional transmission means that the controlled atmosphere system 2 inputs the conditioned gas into the storage body, or the controlled atmosphere system 2 draws the gas to be conditioned from the storage body. The gas regulation and control system 9 controls the turning off of the high-voltage pulse electric field 5 based on the total flow rate of the controlled atmosphere gas.

[0084] The gas regulation control system 9 determines the gas regulation stage based on the comparison between the gas concentration of the gas in the storage and the preset concentration and the preset concentration range, the comparison between the temperature in the storage and the first preset temperature and the second preset temperature, and the comparison between the total flow rate of the gas in the storage and the storage capacity;

[0085] The gas regulation stage includes: a pre-cooling stage, a gas-controlled cold storage operation stage and a stable maintenance stage.

[0086] The return air temperature sensor is provided at the return air end 62 of the air curtain pressure differential refrigeration system 6 and is used to obtain the return air temperature;

[0087] During the stable maintenance phase, the gas regulation and control system 9 controls the switching of the cooling mode of the air curtain pressure difference cooling system 6 based on the comparison between the return air temperature and the second preset temperature, and the temperature inside the storage chamber and the second preset temperature.

[0088] The atmosphere-controlled cold storage further comprises: a refrigeration unit 1 , wherein the evaporator of the refrigeration unit 1 is arranged near the air outlet end 61 of the air curtain pressure difference refrigeration system 6 , and is used to cool the gas blown out of the air outlet end 61 .

[0089] The air curtain type pressure differential refrigeration system performs efficient, fast, energy-saving and low-dry-loss pre-cooling, and cooperates with the high-voltage pulse electric field to effectively and thoroughly sterilize and remove odors from the controlled atmosphere gas, solving the problems of slow pre-cooling speed, slow construction of the controlled atmosphere environment, sterilization dead corners and storage odor in traditional controlled atmosphere cold storage.

[0090] For technical issues related to regional power resource shortages and high electricity costs, please refer to Figure 2 , this embodiment also provides a solar power generation system.

[0091] The solar power generation system includes a concentrator, a heat absorber, an energy storage device, an engine and a power conversion device.

[0092] The concentrator and the heat absorber are arranged on the outer shell of the atmosphere-controlled cold storage, the heat absorber is arranged below the concentrator, and the energy storage device, the engine and the power conversion device are arranged in the atmosphere-controlled cold storage.

[0093] The concentrator collects solar radiation to the absorber to absorb heat energy, and the heat energy is transmitted all the way through the engine to the power conversion device, which charges the battery and supplies energy to the power system of the gas-controlled cold storage.

[0094] The other path enters the energy storage device. When there is sufficient sunlight, part of the heat energy absorbed by the heat absorber is directly converted into electrical energy through the engine, and the other part is stored in the energy storage device. When there is insufficient sunlight, the energy storage device can transfer the heat energy directly to the engine or indirectly to the engine through the heat absorber to ensure the stable energy supply of the power system of the controlled atmosphere cold storage.

[0095] When there is insufficient sunlight and the energy storage device has no stored heat energy, the battery can indirectly supply energy to the power system of the atmosphere-controlled cold storage through the power conversion device, thereby ensuring the stable energy supply of the power system of the atmosphere-controlled cold storage.

[0096] The concentrator can adopt a micro-angle parabolic reflective concentrator, the heat absorber can adopt a tubular composite phase change material heat absorber, the energy storage device can adopt a molten salt energy storage device, the engine can adopt a Stirling engine, the power conversion device includes: a programmable inverter, a dynamic self-regulating transformer, a Master filter rectifier, an automatic power regulator, a temperature-controlled uninterruptible power supply, a dynamic voltage restorer, etc., and the battery can adopt a high-density lithium battery energy storage module.

[0097] The battery converts direct current into alternating current through the programmable inverter of the power conversion device to supply energy to the power system of the atmosphere-controlled cold storage.

[0098] The solar power generation system designed in the present invention can directly and continuously supply energy to the power system of the atmosphere-controlled cold storage when there is sufficient sunlight, and store part of the thermal energy in the energy storage device and part of the electrical energy in the battery. When there is insufficient sunlight, the dual energy storage device can continue to stably supply energy to the power system of the atmosphere-controlled cold storage to ensure the normal operation of the entire atmosphere-controlled cold storage.

[0099] See also Figure 3 , the present application also provides a high-voltage pulse electric field, including: a voltage regulator, a main step-up transformer, a filter rectifier, a capacitor, a gate driver, a MOS tube, a secondary step-up transformer and upper and lower plates;

[0100] The input end of the voltage regulator is connected to the AC power output by the power conversion device, and the output end is connected to the primary coil of the main step-up transformer to adjust the input voltage and perform a primary step-up;

[0101] The secondary coil of the main step-up transformer is connected to the filter rectifier to perform AC-DC conversion on the high voltage after the primary step-up and output high-voltage DC power. The output end of the filter rectifier is connected in series with a capacitor to charge the capacitor.

[0102] The gate drive input receives an external control signal, and the output is connected to the gate of the MOS tube to control its on and off. The drain of the MOS tube is connected between the capacitor and the positive output of the filter rectifier, and the source is connected between the negative output of the filter rectifier and the end of the primary coil of the secondary step-up transformer to form a pulse discharge circuit.

[0103] The head end and tail end of the secondary coil of the secondary step-up transformer are connected to the upper plate and the lower plate respectively to perform secondary step-up, outputting high-voltage pulses to the upper and lower plates to form a strong electric field to sterilize and remove odors from the gas flowing between the plates.

[0104] The upper and lower electrode plates are arranged in parallel outside the communication passage between the gas conditioning system and the interior of the storage body. The secondary coil of the main step-up transformer is grounded.

[0105] The output end of the power conversion device is connected to the voltage regulator through a fuse and a relay; a high-voltage closing relay is provided on the circuit consisting of the voltage regulator and the main step-up transformer;

[0106] A bridge rectifier is shown in the drawings of this embodiment, and other filter rectifiers may also be used in other embodiments.

[0107] Working principle of high voltage pulse electric field:

[0108] Because the output pulse peak voltage needs to be controllable, the AC power directly output by the solar power generation system via the power conversion device or the AC power output by the power conversion device's programmable inverter is input to the input of the main step-up transformer through a voltage regulator. The high AC voltage after the initial step-up is filtered and rectified by the filter rectifier, and then charges the capacitor. The gate drive then turns on the MOS transistor, discharging the capacitor and then performing a second step-up through the secondary step-up transformer. Finally, the pulse voltage is supplied to the upper and lower plates for use.

[0109] The high-voltage pulse electric field of the present application can generate a square output wave with a narrower spacing through the MOS tube controlled by the gate drive, thereby improving the effectiveness of sterilization and odor removal. At the same time, the temperature rise effect is low, reducing the adverse factors for refrigeration of the atmosphere-controlled cold storage.

[0110] The atmosphere-controlled cold storage is an integrated, strong, rigid, and shockproof structure that can easily meet vehicle transportation conditions. The interior of the storage body 12 is filled with a self-foaming process. A through slot 4 is provided at the bottom of the atmosphere-controlled cold storage for forklift transportation, and lifting ears are provided at the four corners of the top of the atmosphere-controlled cold storage for lifting transportation.

[0111] In one embodiment, the entire storage body 12 is 7.5 meters long, 2 meters wide, and 2.5 meters high. The slot 4 is located 4.5 meters away from the door of the storage body. One side of the atmosphere-controlled cold storage is the storage body 12, and the other side is equipped with refrigeration unit 1, atmosphere-controlled system 2, battery 3, and gas regulation and control system 9. Therefore, the storage body 12 side is lighter than the other side. The slot 4 is opened on the side close to the equipment, which keeps it stable when transported by forklift. Lifting ears are located at the four corners of the top of the atmosphere-controlled cold storage to facilitate crane lifting.

[0113] Second embodiment:

[0114] See also Figure 4 This embodiment provides a gas regulation method. Optionally, the method steps of this embodiment can be performed by a gas regulation control system. The gas regulation method includes:

[0115] Step 401: After the controlled atmosphere cold storage is started, it enters the pre-cooling stage. The air curtain pressure differential refrigeration system 6 pre-cools the storage body to reach the first preset temperature T1. The controlled atmosphere system 2 pre-reduces the concentration of the controlled atmosphere gas in the storage body to reach the preset concentration and then enters the controlled atmosphere cold storage operation stage.

[0116] Step 402, during the operation phase of the controlled atmosphere cold storage, the air curtain pressure differential refrigeration system 6 further cools the interior of the cold storage to a second preset temperature T2, the controlled atmosphere system 2 further reduces the concentration of the controlled atmosphere gas in the cold storage, and the high-voltage pulse electric field 5 sterilizes and removes odors in the cold storage, and then enters the stable maintenance phase;

[0117] Step 403, the stable maintenance stage, the air curtain pressure difference refrigeration system 6 performs low-speed refrigeration on the storage body to maintain the temperature inside the storage body, and regularly starts the gas conditioning system 2 and the high-voltage pulse electric field 5 to maintain the environment inside the storage body.

[0118] See also Figure 5 , the pre-cooling stage specifically includes:

[0119] Step 501: The air curtain pressure differential refrigeration system 6 starts the forced refrigeration mode to reduce the temperature inside the refrigerator to a first preset temperature T1;

[0120] When the air curtain pressure differential refrigeration system 6 is in the forced cooling mode, the wind speed at the air outlet end of the air curtain pressure differential refrigeration system 6 is set to the first air outlet speed V1, and the wind speed at the return air end of the air curtain pressure differential refrigeration system 6 is set to the first return air speed V2; a strong pressure difference is achieved by controlling the wind speeds at the air outlet end and the return air end of the air curtain pressure differential refrigeration system 6, thereby accelerating the air flow circulation in the storage, and quickly pre-cooling the atmosphere-controlled cold storage, thereby quickly reducing the physiological and biochemical reactions of fruits and vegetables.

[0121] Step 502: When the temperature in the storage tank drops to the first preset temperature T1, the gas conditioning system 2 is started to reduce the concentration of the gas in the storage tank to the preset concentration;

[0122] The concentration of controlled atmosphere gas is pre-lowered to avoid abnormal stress in the physiological and biochemical reactions of fruits and vegetables caused by sudden changes in the gas environment, and to reduce the time required to reach the preset range.

[0123] In some embodiments, the atmosphere-controlled cold storage is turned on through the control panel 11, and the solar power generation system or the battery 3 supplies power to the atmosphere-controlled cold storage. At this time, the air curtain pressure difference refrigeration system 6 is in the forced cooling mode, and detects whether the temperature in the storage is reduced to the first preset temperature T1; when the temperature in the storage is reduced to the first preset temperature T1, the atmosphere-controlled system is turned on to adjust the concentration of the atmosphere-controlled gas in the storage, and the oxygen concentration in the storage is reduced to the preset oxygen concentration X0, the carbon dioxide concentration is reduced to the preset carbon dioxide concentration Y0, and the ethylene concentration is reduced to the preset ethylene concentration Z0.

[0124] See also Figure 6 The operation stage of the atmosphere controlled cold storage specifically includes:

[0125] Step 601: The air curtain pressure differential refrigeration system 6 starts the normal refrigeration mode to reduce the temperature inside the refrigerator to a second preset temperature T2, where T2 is lower than the preset temperature in the pre-cooling stage;

[0126] When the curtain pressure differential refrigeration system 6 is in normal cooling mode, the wind speed at the outlet end of the air curtain pressure differential refrigeration system 6 is set to the second outlet wind speed V3, and the wind speed at the return air end of the air curtain pressure differential refrigeration system 6 is set to the second return air speed V4; the wind speeds at the outlet end of the air curtain pressure differential refrigeration system 6 and the return air end of the air curtain pressure differential refrigeration system are appropriately reduced to maintain an appropriate pressure difference to avoid drying out of the surface of fruits and vegetables during long-term operation.

[0127] Step 602: When the temperature in the storage tank drops to the second preset temperature T2, the gas conditioning system 2 is started to reduce the concentration of the gas in the storage tank to within the preset concentration range;

[0128] Step 603: When the concentration of the gas in the controlled atmosphere is reduced to a preset concentration range, the high-voltage pulse electric field 5 is activated, and the total flow rate Q0 of the controlled atmosphere gas transmitted in one direction between the controlled atmosphere system and the storage is obtained as detected by the flow meter 82;

[0129] Step 604, when Q0 ≥ kV0, turn off the high voltage pulse electric field 5;

[0130] Among them, V0 is the storage capacity, k is the first proportional coefficient, and its value range is 2 to 5.

[0131] For example, k=3, which means that when the total flow of the controlled atmosphere gas transmitted unidirectionally between the controlled atmosphere system 2 and the storage is greater than or equal to 3 times the storage capacity, the high-voltage pulse electric field 5 is turned off.

[0132] In some embodiments, when the concentration of the controlled atmosphere gas in the warehouse drops to a preset concentration, the air curtain pressure difference refrigeration system 6 starts the normal refrigeration mode; it detects whether the temperature in the warehouse drops to a second preset temperature T2. When the temperature in the warehouse drops to the second preset temperature T2, the controlled atmosphere system 2 is turned on to adjust the concentration of the controlled atmosphere gas in the warehouse. When the oxygen concentration in the warehouse drops to the preset oxygen concentration range X1, the carbon dioxide concentration drops to the preset carbon dioxide concentration range Y1, and the ethylene concentration drops to the preset ethylene concentration range Z1, the high-voltage pulse electric field 5 is turned on for sterilization and odor removal, and the total flow rate Q0 of the controlled atmosphere gas detected by the flow meter is obtained. When Q0 ≥ kV0, it is considered that complete sterilization and odor removal treatment has been carried out, and the high-voltage pulse electric field 5 is turned off.

[0133] The first preset temperature T1 is greater than the second preset temperature T2.

[0134] See also Figure 7 , the stable maintenance stage specifically includes:

[0135] Step 701: The air curtain pressure differential refrigeration system 6 starts the low refrigeration mode to maintain the temperature inside the storage;

[0136] When the curtain pressure differential refrigeration system 6 is in low refrigeration mode, the wind speed at the outlet end of the curtain pressure differential refrigeration system 6 is set to the third outlet wind speed V5, and the wind speed at the return air end of the curtain pressure differential refrigeration system 6 is set to the third return air speed V6 to maintain the temperature in the warehouse.

[0137] Step 702: The gas conditioning system 2 is started at a predetermined time interval of t1. When t1 is reached, the gas conditioning system 2 is started to adjust the concentration of the gas in the storage to a preset concentration range to maintain the gas environment in the storage.

[0138] Step 703, the high-voltage pulse electric field 5 is turned on at a time interval of t2. When the time t2 is reached, the high-voltage pulse electric field 5 is started. When Q0 ≥ kV0, the high-voltage pulse electric field 5 is turned off to control the content of microorganisms and odor.

[0139] In some embodiments, when Q0≥kV0, the air curtain pressure difference refrigeration system 6 starts the low refrigeration mode, and at the same time, the gas conditioning system 2 is regularly turned on every t1 time, and the high-voltage pulse electric field 5 is regularly turned on every t2 time to maintain the gas environment in the warehouse, control the content of microorganisms and odors, and maintain the storage quality of fruits and vegetables, thereby achieving stable long-term operation of the entire gas-conditioned cold storage.

[0140] The stable maintenance stage also includes:

[0141] Real-time detection of return air temperature T3;

[0142] When T3≥mT2, the air curtain pressure difference refrigeration system 6 starts the normal refrigeration mode. When the temperature inside the warehouse is lower than the second preset temperature T2, the air curtain pressure difference refrigeration system 6 starts the low refrigeration mode to maintain the temperature inside the warehouse, giving priority to precise temperature control to keep the temperature inside the warehouse always within the optimal temperature range.

[0143] Wherein, m is the second proportional coefficient, and its value range is 1.1 to 1.4.

[0144] The first outlet air speed V1, the first return air speed V2, the second outlet air speed V3, the second return air speed V4, the third outlet air speed V5 and the third return air speed V6 satisfy the following relationship:

[0145] V1>V3>V5, V2>V4>V6;

[0146] V2>V1, V4>V3, V6>V5.

[0147] See also Figure 8 , this application also discloses a preferred embodiment of a gas regulation method:

[0148] Pre-cooling stage: first, the atmosphere-controlled cold storage is turned on through the control panel 11, and the battery 3 or the solar power generation system energizes the electricity system of the atmosphere-controlled cold storage. The air curtain pressure differential refrigeration system 6 starts to work in the forced cooling mode. The wind speed at the outlet end of the air curtain pressure differential refrigeration system 6 is set to the first outlet wind speed V1 (V1 speed range is 2.5-3m / s), and the wind speed at the return air end of the air curtain pressure differential refrigeration system 6 is set to the first return air speed V2 (V2 speed range is 4-4.5m / s). The refrigeration temperature is set to the first preset temperature T1 (T1 temperature is 10-12°C). When the temperature in the storage reaches T1, the atmosphere-controlled system 2 is turned on, wherein the processing parameters are set to the preset oxygen concentration X0 (X0 concentration ≦10.0%), the preset carbon dioxide concentration Y0 (Y0 concentration ≦0.5%), and the preset ethylene concentration Z0 (Z0 concentration ≦50ppm). This stage is the pre-cooling stage, and the air curtain pressure differential refrigeration system 6 starts to work in the forced cooling mode. It realizes a strong pressure difference by controlling the wind speed on both ends, accelerates the air flow circulation in the warehouse, and quickly pre-cools the controlled atmosphere cold storage, which plays a role in quickly reducing the physiological and biochemical reactions of fruits and vegetables. At the same time, the concentration of the controlled atmosphere gas is pre-reduced to avoid the occurrence of abnormal stress effects on the physiological and biochemical reactions of fruits and vegetables caused by sudden changes in the gas environment, and reduce the time required to reach the set parameter value.

[0149] Atmosphere controlled cold storage operation stage: The air curtain pressure differential refrigeration system 6 starts working in normal refrigeration mode, the air outlet wind speed of the air curtain pressure differential refrigeration system 6 is set to the second air outlet wind speed V3 (V3 speed range is 1-1.5m / s), the return air speed of the air curtain pressure differential refrigeration system 6 is set to the second return air speed V4 (V4 speed range is 2-2.5m / s), and the refrigeration temperature is set to the second preset temperature T2 (T2 temperature is 4-6℃). When the temperature in the storage reaches T 2, the gas conditioning system 2 is turned on, wherein the processing parameters are set to the oxygen concentration range X1 (4% ≦ X1 concentration ≦ 5%), the carbon dioxide concentration range Y1 (0.01% ≦ Y1 concentration ≦ 0.1%), and the ethylene concentration range Z1 (10ppm ≦ Z1 concentration ≦ 25ppm). When the gas conditioning parameters are reached, the high-voltage pulse electric field 5 is turned on, and the total flow rate Q0 of the gas conditioning gas passing through is recorded by the flow meter 82. When Q0 ≥ 3V0 (V0 = 25m 3), turn off the high-voltage pulse electric field 5 and stop the sterilization and odor removal treatment. This stage is the operation stage of the atmosphere-controlled cold storage. The air curtain pressure difference refrigeration system 6 starts the normal refrigeration mode, appropriately reduces the wind speed on both ends, maintains an appropriate pressure difference, and avoids the phenomenon of dry loss on the surface of fruits and vegetables during long-term operation. Then the atmosphere-controlled cold storage system 2 starts to control the concentration of oxygen, carbon dioxide, ethylene and other gases in the storage. When the gas concentration reaches the preset concentration range, turn on the high-voltage pulse electric field 5 for sterilization and odor removal. V0 is the actual storage capacity. When the storage capacity V0 is cycled three times, it is considered that the sterilization and odor removal treatment has been completely carried out. After further cooling, atmosphere-controlled treatment, sterilization and odor removal, the entire atmosphere-controlled cold storage fully reaches the set parameters and enters the stable maintenance stage.

[0150] Stable maintenance stage: The air curtain pressure differential refrigeration system 6 starts working in low cooling mode, the outlet wind speed of the air curtain pressure differential refrigeration system 6 is set to the third outlet wind speed V5 (the speed range of V5 is 0.1~0.3m / s), and the return wind speed of the air curtain pressure differential refrigeration system 6 is set to the third return wind speed V6 (the speed range of V6 is 0.5~0.8m / s). At the same time, the gas conditioning system 2 is regularly turned on every t1 time (48h≦t1≦60h), and the high-voltage pulse electric field 5 is regularly turned on every t2 time (24h≦t1≦36h) to maintain the gas environment in the warehouse, control the content of microorganisms and odors, and play a role in stabilizing the storage quality of fruits and vegetables. This stage is the stable maintenance stage. The gas conditioning system 2 is regularly turned on to maintain the stability of the gas environment in the warehouse, and the high-voltage pulse electric field 5 is regularly turned on to sterilize and remove odors, so as to achieve stable and long-term operation of the entire gas-conditioned cold storage. When the return air temperature T3≧1.2T2, the air curtain pressure difference refrigeration system 6 starts the normal refrigeration mode. When the temperature inside the warehouse is lower than the second preset temperature T2, the air curtain pressure difference refrigeration system 6 starts the low refrigeration mode to maintain the temperature inside the warehouse, giving priority to precise temperature control to keep the temperature inside the warehouse always within the optimal temperature range.

[0153] The pre-cooling operation module 901 is used to enter the pre-cooling stage after the gas-controlled cold storage is started. The air curtain pressure differential refrigeration system pre-cools the storage body to reach the first preset temperature T1. The gas-controlled system pre-reduces the concentration of the gas-controlled gas in the storage body to reach the preset concentration before entering the gas-controlled cold storage operation stage.

[0154] In the atmosphere-controlled cold storage operation module 902, during the atmosphere-controlled cold storage operation phase, the air curtain pressure differential refrigeration system further cools the interior of the cold storage to a second preset temperature T2. The atmosphere-controlled system further reduces the concentration of the atmosphere-controlled gas in the cold storage, and the high-voltage pulse electric field sterilizes and removes odors in the cold storage, and then enters the stable maintenance phase.

[0155] The stable maintenance module 903 is used for the stable maintenance stage. The air curtain pressure difference refrigeration system performs low-speed cooling on the warehouse body and regularly starts the gas conditioning system and the high-voltage pulse electric field to maintain the environment inside the warehouse.
