中国南极天文台所在的南极Dome A地区属于低温低气压环境，用于存储天文观测数据的海量存储系统在此环境下很难正常工作。为给海量存储系统提供稳定的工作环境，设计了一套适应低温低压的恒温恒压装置，包括具有特殊结构的保温密封箱，以及针对此特殊结构设计的温度控制系统和气压控制系统。为适于装置的长期无人值守运行，增强装置的可靠性，系统硬件和软件均采用了冗余控制方案，从而免受环境因素干扰。

The Antarctic Dome A area is under low temperature and pressure where the Chinese Antarctic observatory works. The mass storage system used to store the astronomical observation data can’t work normally in the bad environment. In order to provide a stable working environment for the mass storage system, a constant temperature and pressure appliance which adapts to the low temperature and pressure environment was designed .The appliance includes the heat preservation and hermetic sealing box with special structure , the temperature and pressure control system which was designed according to the special structure. Redundancy control scheme for hardware and software was used to enhance the reliability of the appliance and to ensure that the appliance can work long in the unattended mode. Finally, the appliance can protect the mass storage system from the interference of environmental factors.
