A refrigerating device for a water station comprises cold storage cabinet, cold water container and refrigerating system. Said cold water container is installed in the cold storage cabinet, one end of which is connected to a water storage pail via a pipeline, and the other end is provided with a water intake pipeline. The cold water container is used for holding water that needs temperature drop. Said refrigerating system comprises compressor, condensator, capillary tubes, first evaporator and refrigerating pipelines. Said first evaporator can be installed in the cold storage cabinet or can also be installed outside the cold storage cabinet in coordination with it. Said compressor is installed under the cold storage cabinet, said refrigerating pipelines are filled with refrigerating liquid. The refrigerating device for water station of the present invention has the following advantages: the structure being simple and rational, the speed of refrigeration quick, the heat stability excellent and the utilization ratio of cold capacity high.
