The invention provides a refrigerating device. The refrigerating device comprises a thermal-insulation cavity, a coil pipe, a refrigerant storage tank and a refrigerant recycling device, wherein the coil pipe is located in the lower half of the inner space of the thermal-insulation cavity, the inlet of the coil pipe penetrates the wall of the thermal-insulation cavity to be connected with one end of a refrigerant channel, the other end of the refrigerant channel is communicated with the refrigerant outlet of the refrigerant storage tank, and the outlet of the coil pipe penetrates the wall of the thermal-insulation cavity to be communicated with the refrigerant recycling device. The refrigerating device has the advantages that the device uses the coil pipe located in the lower space of the thermal-insulation cavity to achieve refrigeration, temperature horizontal distribution evenness in the low-temperature storage space can be achieved, stable operation can be achieved, the temperature of the low-temperature storage space can be regulated flexibly, and the problem that cold air or a refrigerating medium easily diffuses upwardly to threat the stable and reliable operation of a mechanical mechanism or an automatic mechanism on the upper portion is solved.
