Abstract: In order to protect the memory files and objects, special requirements are put forward for the temperature, atmospheric humidity and air cleanliness of the internal environment. The idea of independent control of temperature and atmospheric humidity and remote control technology are using to build a multi-source thermostatic cycle system with temperature and atmospheric humidity cascade adjustment. The collected parameters such as temperature, humidity and air dust content are converted into wireless network signals through the wireless network converter. It is then transmitted to the central control system. Finally, the scientific management and energy consumption optimization of the environment of archival repository are realized. The energy saving rate of the core technology of environmental monitoring and adjustment system of archival repository is up to 20%. The related technology can also be applied to agricultural dryer, thermostatic swimming pool, tall building air-conditioning system and refrigeration equipment performance research and test laboratory.
