Summary: This standard specifies the order of liquefied gas as the refrigerant, the design pressure is not higher than 4MPa, design temperature not higher than 200��C refrigeration apparatus pressure vessels (including shell and tube heat exchanger, hereinafter referred to as the "container") design, manufacture, inspection and acceptance requirements. Refrigeration cycle operation of the device should be a vapor compression refrigeration cycle and similar cycles (including heat pumps). This standard does not apply inside diameter (rectangular section refers to the diagonal) less than 150mm or volume of less than 0. 025m3 container, without casing pipe heat exchanger, cooled exhaust pipes and direct-fired absorption chiller unit generator. Can not be used to determine the structure of the standard size of pressure components, allowing the design of the following methods, but subject to the national pan retaining pressure vessel and the National Standardization Technical Committee of Standardization Technical Committee of refrigeration and air conditioning equipment assessed recognition: a) including finite element method, including stress analysis, b) with the comparable structure has been put into use to compare empirical design.
