Zusammenfassung:	The application discloses a single-working-medium cascade type brine refrigeration system and a cold supply system, and belongs to the technical field of refrigeration and cold supply. The refrigeration system comprises a high-temperature-stage system and a low-temperature-stage system; the high-temperature-stage system continuously operates to provide refrigeration circulation; and the low-temperature-stage system continuously exchanges heat with a working medium of the high-temperature-stage system in a condensation evaporator, and prepares low-temperature brine of -40 DEG C under the effects of a second throttling device, a low-temperature brine evaporator and a low-temperature-stage compressor. The cold supply system comprises a brine circulation system and a user side circulation system, wherein the brine circulation system comprises the refrigeration system; and the low-temperature brine prepared by the refrigeration system continuously exchanges heat with a hydraulic module under the effect of a low-te
