How long is the distribution cycle of warehouse temperature and humidity verification?

Record the external weather, temperature and humidity every day. Summarize the data of the first seven days of each season, draw the temperature and humidity time curve, find out the position where the temperature and humidity fluctuate the most and the time when the warehouse temperature is the highest, and determine the hanging position of the temperature and humidity meter and the time to monitor the temperature and humidity every day. Summarize the temperature and humidity change curve, confirm that the warehouse can meet the temperature and humidity control requirements under the worst conditions (65438+ 10 and July), and evaluate the effectiveness of the corresponding cooling and dehumidification facilities. ?

After summing up, reconfirm the position where the temperature and humidity fluctuate the most in each season and the time when the warehouse temperature is the highest, and determine the hanging position of the thermometer in the four seasons and the time for monitoring the temperature and humidity every day. Note: Shaanxi seasonal division: spring: changing seasons in late February; Summer: changing seasons in early June; Autumn: change seasons in late September; Winter:165438+1enter the season at the end of October. The results show that under extreme conditions, such as long-term high temperature, cold air southward and long-term rainfall, some points will exceed the standard, but the MKT value of the whole year should not exceed the standard. MKT: Average exercise temperature (average? Kinetic energy? What is the relationship between Kelvin and Celsius? The value of K=℃+273. 1MKT is usually higher than the ordinary arithmetic mean. MKT is used to evaluate the temperature fluctuation during product storage. HD is the activation energy, which is equal to 83. 144kj/mol (usually for solids and liquids, it is from 60? kj/mol？ To 100kj/mol, unless more accurate information is used). R is a general gas constant, equal to 8.3 14472j/K/mol. T 1 is the average temperature of the first cycle (Kelvin temperature); T2 is the average temperature (Kelvin temperature) of the second cycle ... TN, and the average temperature (Kelvin temperature) of the nth cycle. N represents the total number of recording temperatures. MKT has passed the average storage temperature verification for at least one year, and recorded the average temperature of at least 12 cycles. This value can be calculated manually or by computer software. = Note: The monthly record is a cycle. The period from July of the first year to June of the second year is 1 cycle. 1 After the cycle, summarize the data in time and calculate the MKT value.
