- Scope
- This standard specifies the design, manufacturing, inspection and acceptance requirements for pressure vessels for refrigeration devices that use liquefied gas as the refrigerant, the design pressure is not higher than 4.0MPa, and the design temperature is not higher than 200°C. The working cycle of the refrigeration device should be a vapor compression refrigeration cycle and similar cycles (excluding heat pumps). This standard does not apply to containers with an inner diameter (rectangular cross-section refers to the diagonal) less than 150mm or a volume less than 0.025m^(3), shellless sleeve-type heat exchangers, cooling pipes and direct-fired absorption refrigeration device generator.
