This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).
