The invention is characterized in that the refrigerant is prepared from ammonium bisulfate, ammonium nitrate, sodium sulfite and sodium sulfate added. The weight ratio thereof is 35-45 parts by weight of ammonium hydrogen sulfate, 45-55 parts by weight of ammonium nitrate, 25-35 parts by weight of sodium sulfite, and 90-100 parts by weight of sodium sulfate. The inventive concept is novel, the cost is low, and the cooling effect is good (below -10°C). It is not only beneficial to the user's preparation and use, but also beneficial to environmental protection and has a great application development prospect. Sovereignty Item 1.
