[0003] Under the existing technology, when testing the internal temperature of a cold storage, there is often a lack of standardized processes, resulting in inconsistent and incomparable test results. At the same time, when testing the temperature inside a cold storage, the temperature is often measured at a single measuring point. However, there may be temperature differences in various areas inside the cold storage, which leads to errors in the results of a single measuring point, incomplete testing, and inability to fully evaluate performance.

The number of reduced measuring points is set to no less than 3 points on the same horizontal and vertical measurement lines.
[0008] Furthermore, when conducting the temperature test, the test is carried out in the order of cooling stage, balancing stage, and thermal insulation stage. There is no time limit for the cooling stage test, the balancing stage test time is 10 hours, and the thermal insulation stage test time is 12 hours. Among them, the balance stage test is divided into the main unit stage test and the standby unit stage test. The main unit stage test duration is 6 hours, and the standby unit stage test duration is 4 hours.
[0009] Furthermore, in the stage test, the cooling stage test also includes the following steps: Close the cold storage door and keep it closed during the cooling phase test; According to the requirements of the contract and technical specifications, set the target temperature of the cold storage, record the ambient temperature at the beginning of the test, start the refrigeration equipment of the cold storage and adjust it to automatic mode. During the test, regularly check and record the temperature changes in the cold storage, observe whether the refrigeration equipment is operating normally and whether there is any abnormal noise or vibration; When the temperature in the cold storage reaches the set value, keep the refrigeration equipment running for a period of time and record the refrigeration time.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] In order to solve the problem that there is often a lack of standardized processes when testing the temperature inside the cold storage, resulting in inconsistent and incomparable test results, and that the temperature inside the cold storage is often measured at a single measuring point, but there may be temperature differences in various areas inside the cold storage, resulting in errors in the results of a single measuring point, incomplete testing, and inability to fully evaluate performance, please refer to Figure 1 , the present invention provides the following technical solutions: A temperature testing method for a cold storage system comprises the following steps: Arrangement of measuring points: perform preliminary infrared temperature measurement on the cold storage, and arrange the distribution of air temperature field detection measuring points in the cold storage according to the preliminary measurement results. The air temperature field detection measuring points in the cold storage use temperature and humidity cards to record the measurement data. The temperature and humidity cards are connected with the repeater, receiver, and tablet. The measurement data measured by the temperature and humidity cards are sent to the repeater via wireless communication signals. Stage test: the cold storage is tested in three stages and the test temperature data is collected. The three stages are cooling stage, balance stage and thermal insulation stage. Data processing, obtaining the temperature data detected by the air temperature field detection points in the cold storage at different temperature detection times, and calculating the average air temperature in the cold storage at a specific time during the stage test; The test results are based on the average air temperature data in the cold storage at different times during the stage test calculated during data processing, and a curve chart is generated. Based on the curve chart, the function of the refrigeration equipment of the cold storage system, the continuous working status of the unit, and the insulation effect of the cold storage are judged.
[0020] Specifically, through the initial infrared temperature measurement, the measurement points can be arranged more accurately, and through phased testing, the operating status of the cold storage system can be more fully understood. Each stage has its specific test purpose, so that the performance of the cold storage system can be more accurately evaluated.
[0021] Specifically, through stage tests, a large amount of temperature data can be obtained and processed, the average air temperature in the cold storage at different times can be calculated, and the test results can be presented in the form of a curve chart, making the results more intuitive, easy to understand and analyze. At the same time, the trend and pattern of temperature changes can be more easily discovered through the curve chart, which helps to judge the performance of the cold storage system. Based on the test results, the function of the refrigeration equipment of the cold storage system, the continuous working condition of the unit and the insulation effect of the cold storage can be evaluated.
[0022] The measurement point arrangement includes the following steps: Arrange temperature field detection points on the top of the cold storage, the distance between the top point and the loading line is 50mm-100mm, arrange temperature field detection points on the bottom of the cold storage, the distance between the bottom point and the cold storage floor is 50mm-100mm, arrange horizontal and vertical end points in the cold storage, the horizontal and vertical end points are set on the shelves in the cold storage, the distance between the horizontal and vertical end points and the cold storage wall is 50mm-100mm; Among them, the number of measuring points on each horizontal measurement line is set to be no less than 3 points, and the number of measuring points on each vertical measurement line is set to be no less than 3 points.
[0023] Specifically, by arranging measuring points on the top, bottom and shelves of the cold storage, it is ensured that the temperature field can be effectively measured at all important locations of the cold storage, which can more comprehensively reflect the temperature distribution inside the cold storage and improve the uniformity and representativeness of the test. The distance between the measuring point and the loading line, the cold storage floor and the cold storage wall is controlled within the range of 50mm-100mm. This detail ensures the accuracy of the measuring point position and avoids test errors caused by improper measuring point position.
[0024] Specifically, by properly arranging the number and location of measuring points, unnecessary measurement work can be reduced, thereby improving test efficiency. At the same time, due to the reasonable layout of measuring points, effective temperature data can be collected more quickly, shortening the test cycle.
[0025] The measurement point arrangement also includes the following steps: Conduct an initial infrared temperature measurement inside the cold storage, and use infrared equipment to measure the temperature of the set temperature field detection points; Among them, if the temperature difference between each temperature field detection measuring point is greater than 2°C, it is determined that the temperature field distribution in the warehouse is uneven, and the existing number of temperature field detection measuring points in the cold storage is maintained; if the temperature difference between each temperature field detection measuring point is less than or equal to 2°C, it is determined that the temperature field distribution in the warehouse is uniform, and the existing number of temperature field detection measuring points in the cold storage is reduced. The number of reduced measuring points is set to no less than 3 points on the same horizontal and vertical measurement lines.
[0026] Specifically, by using infrared equipment to conduct an initial test inside the cold storage, we can more accurately understand the distribution of the temperature field inside the cold storage. When the temperature field inside the cold storage is relatively uniform, we can appropriately reduce the number of measuring points, which can reduce the test cost and ensure the accuracy of the test. By dynamically adjusting the number of measuring points, we can reduce unnecessary measurement point settings while ensuring the test accuracy, thereby shortening the test time and improving the test efficiency. It can reduce the manpower, material resources and time costs required for the test, and can also reduce the use of related equipment such as temperature and humidity cards and repeaters, further reducing the test cost.
[0027] See also Figure 2 In the figure, the x-axis is the temperature axis, the y-axis is the time axis, the A stage is the cooling stage, the B stage is the balance stage, the C stage is the thermal insulation stage, the a stage is the main unit stage, and the b stage is the standby unit stage. When performing the temperature test, the test is carried out in the order of the cooling stage, the balance stage, and the thermal insulation stage. In addition, there is no time limit for the cooling stage test, the balance stage test time is 10 hours, and the thermal insulation stage test time is 12 hours; Among them, the balance stage test is divided into the main unit stage test and the standby unit stage test. The main unit stage test duration is 6 hours, and the standby unit stage test duration is 4 hours.
[0028] The cooling phase test also includes the following steps: Close the cold storage door and keep it closed during the cooling phase test; According to the requirements of the contract and technical specifications, set the target temperature of the cold storage, record the ambient temperature at the beginning of the test, start the refrigeration equipment of the cold storage and adjust it to automatic mode. During the test, regularly check and record the temperature changes in the cold storage, observe whether the refrigeration equipment is operating normally and whether there is any abnormal noise or vibration; When the temperature in the cold storage reaches the set value, keep the refrigeration equipment running for a period of time and record the refrigeration time. After the test, record the ambient temperature in the cold storage at the end of the test.
[0029] Specifically, by closing the cold storage door and keeping it closed throughout the test, the closed and stable test environment is ensured. After the temperature in the cold storage reaches the set value, the refrigeration equipment is kept running for a period of time and the refrigeration time is recorded, which helps to understand the operating efficiency and energy consumption of the refrigeration equipment after reaching the target temperature. After the test, the ambient temperature in the cold storage at the end of the test is recorded, which can be compared with the temperature at the beginning of the test to analyze the temperature change trend and refrigeration effect during the test.
[0030] The equilibration phase test also includes the following steps: After the cold storage completes the cooling stage test and the ambient temperature in the cold storage reaches the design temperature, keep the cold storage door tightly closed; Start the host unit and keep it running for 6 hours. During the test, set a temperature detection time every 1 hour and record the temperature data inside the cold storage at the current time, and observe the operating status of the refrigeration unit; After the main unit has been running for 6 hours, stop running the main unit and start the standby unit. Keep the standby unit running continuously for 4 hours. During the test, set a temperature detection time every 1 hour and record the temperature data inside the cold storage at the current time. At the same time, observe the running status of the standby unit. After the test is completed, stop running the standby unit.
[0031] Specifically, by testing the main unit and the standby unit separately, the overall performance and reliability of the cold storage system can be fully evaluated. This complete testing process helps to discover potential performance problems or failure risks and provide guidance for subsequent improvements and maintenance. By analyzing the temperature and operating status data of the main unit and the standby unit at different operating stages, the operating strategy of the cold storage system can be optimized, energy efficiency can be improved, and operating costs can be reduced.
[0032] The thermal insulation stage test also includes the following steps: After the cold storage has completed the balance phase test and the refrigeration unit has stopped running, keep the cold storage door tightly closed; Keep the cold storage in a closed isolation state for 12 hours. During the test, set a temperature detection time every 1 hour and record the temperature data inside the cold storage at the current time. After the 12-hour insulation isolation test, record the last temperature data and turn off the temperature monitoring equipment.
[0033] Specifically, by keeping the cold storage door tightly closed and continuously monitoring the temperature for 12 hours after the refrigeration unit stops operating, it is possible to accurately understand the temperature maintenance capability of the cold storage after it loses its active refrigeration capacity.
[0034] Specifically, during the thermal insulation test, regularly recording temperature data can help detect any abnormal temperature changes. By identifying these changes, potential heat leaks can be discovered and repaired in a timely manner, thereby improving the thermal insulation effect of the cold storage. By analyzing the thermal insulation test data, the temperature changes of the cold storage in different time periods can be understood, thereby optimizing the maintenance strategy.
[0035] Data processing includes the following steps: Select a stage test with a total duration of no less than 36 hours as the test data, obtain the temperature data detected by the air temperature field detection points in the cold storage at different temperature detection times in the test data, take the continuous 24-hour data with the closest beginning and end temperatures, and calculate the average air temperature in the cold storage at a specific time during the stage test based on the data collected by the air temperature field detection points in different cold storages at the same temperature detection time.
[0036] Among them, the following formula is used to calculate the average air temperature in the cold storage at a certain moment during the stage test: In the above formula, T represents the temperature detection time, n represents the total number of air temperature field detection points arranged in the cold storage, represents the average air temperature in the cold storage at time T, and t represents the temperature of the nth test point in the cold storage at time T.
[0037] Specifically, we select stage tests with a total duration of no less than 36 hours as test data to ensure that temperature data is collected over a long enough period of time, so as to more accurately reflect the actual operating status of the cold storage system. At the same time, we take 24 hours of continuous data with the closest temperature at the beginning and end to eliminate the temperature fluctuations that may exist at the beginning and end of the test, and improve the representativeness of the data.
[0038] Specifically, based on the data collected by the air temperature field detection points in different cold storages at the same temperature detection time, the average air temperature in the cold storage at a specific time during the stage test is calculated. This ensures that the temperature data of each measurement point at different times are fully considered, improving the integrity of the test data. By calculating the average air temperature in the cold storage at each temperature detection time, the performance of the cold storage system in different time periods can be more accurately reflected.
[0039] Specifically, this data processing method is applicable to different types of cold storage systems. Whether it is a large or small cold storage, the test requirements can be met by adjusting the number and location of measuring points. It has strong versatility and applicability.
