b) The terms and definitions related to dehumidification performance have been changed (see 3.4 to 3.6, 3.3 to 3.5 of the 2003 edition);

c) Added terms and definitions for standby mode, clean air volume and sterilization rate (see 3.7 to 3.9);

d) The type classification of dehumidifiers has been changed (see 4.1, 4.1.1 and 4.1.2 of the 2003 edition);

e) The requirements for model compilation have been changed (see 4.2, 4.1.4 of the 2003 edition);

f) The basic parameters of the dehumidifier have been changed, including the normal working environment parameters and test operation parameters of the dehumidifier (see 4.3, 4.1.3 and 6.2.1 of the 2003 edition);

g) The general requirements have been changed (see 5.1, 5.1 of the 2003 edition);

h) The requirements on power supplies and components in the original standard have been deleted (see 5.2 and 5.4 of the 2003 edition);

i) The appearance requirements have been changed (see 5.2, 5.10 of the 2003 edition);

j) The dehumidification performance requirements have been changed, and the requirements for high temperature dehumidification performance, overflow insulation performance, and heat exchange restrictions have been added. Test methods (see 5.5, 5.6, 5.10, 5.11, 6.6, 6.7, 6.11 and 6.12, 4.2, 5.5 and 6.2 of the 2003 edition);

k) Added power failure protection requirements and corresponding test methods (see 5.12 and 6.13);

l) Changed the safety and electromagnetic compatibility requirements and adjusted the test methods accordingly (see 5.13, 5.14, 6.14 and 6.15, 2003 edition 5.7);

m) The noise limit requirements have been changed and the noise test method has been added (see 5.15 and Appendix B, 5.6 of the 2003 edition);

n) Added technical requirements and corresponding tests for standby power, mechanical properties of casters, weather resistance, clean air volume, and sterilization rate Methods (see 5.16-5.20, 6.17-6.21);

o) Deleted the provisions on charging refrigerant (see 5.9 of the 2003 edition);

p) The general test conditions and requirements have been changed (see 6.1 to 6.3, 6.1 of the 2003 edition);

q) The inspection rules and requirements have been changed (see 7.1 to 7.3, 7.1 to 7.2 of the 2003 edition);

r) The requirements for labeling, packaging, transportation and storage have been changed (see 8.1 to 8.3, 8.1 to 8.3 of the 2003 edition);

s) The dehumidifier performance test method has been changed (see Appendix A, Appendix A of the 2003 edition);

t) Added the correction method for dehumidification power consumption of static pressure dehumidifiers (see Appendix C).

1 Scope

This document specifies the types and basic parameters, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation and Storage.

This document applies to dehumidifiers that use a vapor compression refrigeration cycle driven by an electric motor to remove moisture. This document does not apply to fresh air dehumidifiers.
