Summary	This standard specifies the types, basic parameters, and technical requirements of large-scale ice-making low-temperature brine units, describes the corresponding test methods, and specifies inspection rules, marking, packaging, transportation, and storage. This standard applies to the manufacture of large-scale ice-making low-temperature brine units with a nominal cooling capacity greater than 50kW, using R717 or fluorinated hydrocarbons as refrigerants in artificial ice rinks. The manufacture of other similar ice-making units should refer to this standard.
