Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T .20108-2006 "low temperature unit type air conditioner". Compared with GB/T .20108-2006, the main changes are as follows.
--- increase the cooling capacity, cooling power consumption, the annual energy efficiency ratio (AEER), air volume, standard air volume, cold air ratio definition (see 3.2,
3.3, 3.5, 3.6, 3.7, 3.8);
- the definition of terminology for the removal of cryogenic conditions;
- modified type classification (see 4.1, 4.2);
--- modified the basic parameters (see 4.3.1, 4.3.2);
- Increased air volume, condensate and condensate removal, yearly energy efficiency (AEER) test conditions and test requirements (see 4.3.3, 5.3.7,
5.3.8, 5.3.13, 6.3.11);
- increased water pressure drop, annual energy efficiency ratio, cold wind ratio requirements and limits (see 5.3.12, 5.3.13, 5.3.14);
- modified general requirements and safety requirements (see 5.1, 5.2);
--- increase the instrument type and accuracy, test conditions parameters of the reading tolerance (see 6.1.4,6.1.5,6.1.6,6.1.7);
- modified test requirements (see 6.2);
- the removal of energy efficiency and minimum load conditions and their corresponding test requirements;
- modified factory inspection and sampling inspection requirements (see 7.1, 7.2);
- modified mark, packaging, transport and storage requirements (see 8.1, 8.2, 8.3);
--- modified the low temperature unit type air conditioner model number in Appendix A (see Appendix A);
- increase the urban temperature distribution coefficient (see Appendix B).
