Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 21363-2008 "volumetric refrigeration compression condensing unit", compared with GB/T 21363-2008, the main technology
The content changes are as follows.
--- Increased refrigerant types (see Chapter 1);
---Modified the test conditions of the unit (see 4.2.2, 4.3.2 of the.2008 version);
--- Increased general requirements for the unit (see 5.1.14 and 5.1.15);
---Modified the electrical safety requirements of the unit and the corresponding test methods (see 5.2.4.5, 6.3.7,.2008, 5.2.4.5, 6.3.7);
--- Modified the noise limit (see 5.3.8, 5.3.8 of the.2008 version);
--- Increased the requirement for temperature measurement point position (see 6.1.5);
--- Modified and deleted some of the test requirements (see 6.2.1,.2008 version of 6.2.1, 6.2.8);
--- Added inspection items for "grounding devices" (see 7.1);
--- Increased requirements for flammable refrigerant signs (see 8.1, 8.2);
--- Removed the model representation of the volumetric refrigeration compression condensing unit (see Appendix A of the.2008 version);
--- Corrected the formula for calculating the heat leakage coefficient and cooling capacity (see Equations A.4, A.16,.2008, B.4, B.16).
