The invention provides a refrigeration device. The refrigeration device comprises a device body and a pressure control assembly. The device body comprises an accommodating space which is used for accommodating a refrigerant; the pressure control assembly is used for controlling evaporation/sublimation pressure and is connected with the device body, so that the accommodating space is communicated with an external fluid of the device body; the pressure control assembly comprises a shut-off valve used for opening or closing communication between the containing space and the outside of the device body. In this way, the temperature around the device can be kept constant. The invention further provides a cold insulation box, the cold insulation box comprises an in-box space, the refrigerating device is arranged, and the refrigerating device communicates with the containing space of the refrigerating device and the outside of the cold insulation box through a pressure control assembly. 本发明提供一种制冷装置，包含装置本体以及压力控制组件。装置本
