In summary, as a preferred embodiment, the cultural relic storage system provided by the present invention can implement three working modes: "low temperature and constant humidity mode", "constant humidity and low oxygen mode", and "low temperature, constant humidity and low oxygen mode".

The realization method of "low temperature and constant humidity mode" is as follows: when the low temperature and constant humidity mode is selected through the display screen, the temperature value is set to 2℃ and the humidity is 65%RH. After the system is powered on, the control system 1 automatically starts the refrigeration unit 7 to cool down. During the temperature adjustment process, when the humidity in the enclosed space is lower than the set value of 65%RH, the control system 1 automatically starts the humidifier, the first solenoid valve 9 is closed, the second solenoid valve 5 is opened, and the air compressor 3, The nitrogen generator 4 stops working, the gas in the enclosure space 8 returns to the air inlet of the humidifier through the first connecting pipe, and the gas is humidified by the humidifier and then enters the enclosure space 8 again, thereby affecting the enclosure space 8 The gas is humidified in a loop. On the contrary, dry gas is filled to reduce the humidity in the enclosed space 8. When the temperature in the enclosure 8 is close to the set value, the control system 1 turns on the thermal compensator and regulates the heating capacity of the thermal compensator through PID technology to maintain the stability of the temperature in the enclosure 8 until the temperature in the enclosure 8 The humidity reaches the set value. In the process of temperature control, the refrigeration unit 7 and the thermal compensator are always in working state to cope with the influence of environmental temperature changes on the temperature of the enclosed space, so that the temperature in the enclosed space is in a stable working state. When the temperature and humidity are both qualified, the control system 1 automatically turns off the thermal compensator and the refrigeration unit 7.

The realization method of the "constant humidity and low oxygen mode" is: when the control system 1 selects the constant humidity and low oxygen mode, after the system is powered on, the control system 1 automatically starts the air compressor 3 and the nitrogen generator 4. In the process of reducing oxygen, when the humidity in the enclosed space is lower than the lower limit of the set value, the control system 1 automatically starts the humidifier; when the humidity in the enclosed space is higher than the upper limit of the set value, the control system 1 automatically turns off humidification The gas flows through the gas path of the humidifier, but the gas is not humidified. When the oxygen concentration in the enclosed space reaches the set value, the control system 1 automatically adopts closed-loop humidification or open-loop dehumidification according to the humidity detection result in the enclosed space to perform humidity control. Closed-loop humidification means that the air compressor 3 and the nitrogen generation unit stop working, the first solenoid valve 9 is closed, the second solenoid valve 5 is opened, and the gas in the enclosed space returns to the air inlet of the humidifier through the first connecting pipe. Cyclically humidify the gas in the enclosed space. The open loop dehumidification is to replace the high humidity gas in the space with the dry gas of the nitrogen generator 4. The specific implementation process is that the air compressor 3, the nitrogen production unit work, the humidification unit 6 stops working, and the dry nitrogen is introduced into the airtight space, and the gas with high humidity in the airtight space is discharged to play the role of dehumidification (at this time, the air The oxygen content of the gas in the dense space is lower than the set value, which meets the requirements of hypoxia preservation).

The "low temperature, constant humidity and low oxygen mode" is implemented as follows: when the system selects the low temperature, constant humidity and low oxygen mode, after the system is powered on, the control system 1 automatically starts the refrigeration unit 7 to cool the enclosed space first. During the cooling process, when the temperature in the enclosed space reaches the upper return difference of the set value, the control system 1 automatically starts the nitrogen generator 4 to start reducing oxygen. During the cooling process, when the humidity in the enclosed space is lower than the set value, the system will automatically start the humidifier. If the temperature in the enclosed space reaches the set value first, the control system 1 continues to reduce oxygen and control humidity; if the oxygen concentration in the enclosed space first reaches the set value, the system continues to cool and control humidity; if the temperature and oxygen in the enclosed space When the content reaches the set value, the system automatically closes the first solenoid valve 9 and opens the second solenoid valve 5 to perform closed-loop humidification.

The above-mentioned embodiments are only used to illustrate the present invention, not to limit the present invention. Those with ordinary knowledge in the technical field can make various changes and modifications without departing from the scope of the present invention. Therefore, all Equal technical solutions should also belong to the scope of the disclosure of the present invention.
