Summary
This standard specifies pressure vessels for refrigeration equipment (including shell-and-tube heat exchangers for refrigeration equipment, hereinafter referred to as "containers") that use liquefied gas as refrigerant, design pressure not higher than 5.0MPa, and design temperature not higher than 200�� Requirements for design, manufacturing, inspection and acceptance. The working cycle of the refrigeration device should adopt a vapor compression refrigeration cycle and a heat pump and other similar cycles. This standard does not apply to the following pressure vessels: 1. Vessels with an inner diameter (for vessels with non-circular cross-sections, the maximum geometric size of the inner boundary of the section) less than 150mm or with a volume less than 0.03m^3; 2. Exchangers, cooling pipes, plate heat exchangers, etc.; 3. Generators for direct-fired absorption refrigeration devices. Containers or pressure components whose structural dimensions cannot be determined by this standard are allowed to use the following
