Standard  and Energy Efficiency Rating  Labeling and Inspection  of 
Non-ducted A ir Conditioning Machines  (Draft) 
Subject：Announcement for the Requirements on Minimum Energy Performance 
Standard and Energy Efficiency Rating Labeling and Inspection of 
Non-ducted Air Conditioning Machines  
Basis： Paragraph 4, Article 14 of the Energy Management Act  
Announcement ： 
1. Domain ： The non-ducted c onditioning machines (or air conditioners ) denoted in this 
announcement are those meeting the definition of air conditioners with rated cooling 
capacity below 71kW,  defined in CNS 3615 , CNS 14464, and CNS 15712 -1, and 
promulgated by the Bureau o f Standards, Metrology and Inspection (BSMI) of the 
Ministry of Economic Affairs (MOEA) as products requiring inspection before 
marketing.  
2. Test Method ： 
(i)The cooling seasonal performance factor (CSPF) of air conditioners shall be tested 
according to CNS 3615, CNS 14464, and CNS 15712 -1. 
(ii) The rated cooling capacity, rated middle cooling, rated electrical power input of 
cooling, and rated electrical power inp ut of middle cooling shall be measured , while 
under T1 ambient test condition define d in CNS 14464 and CNS 15712 -1. 
(iii)Afterward, the cooling seasonal total load (CSTL) and the cooling seasonal electrical 
consumption (CSEC) shall be calculated by CNS 15712-1. 
3. M inimum Energy Performance Standard  (MEPS)：The value of CSPF calculated from 
the previous tested values shall not be less than the standard  value  specified in the Table 
1 (minimum energy performance standard  requirements  for non-ducted air condition ers) 
and be more than 95% of the marked value on products . 
4. Labeling scheme for Energy Efficiency Rating   2(1) Displayed label minimum  size：180mm  (long)120mm(width) , its samples and 
specifications  as follow： 
     
 
   
(2) Content of energy efficiency rating label 
(i) Product name ( air conditioning machine ); 
(ii) Product model number ; 
(iii) Rated cooling capacity (kW); 
(iv) Cooling seasonal performance factor , CSPF  (kWh/kWh) ; 
(v) Energy efficiency rating ; 
The products shall be classified for energy efficiency rating based on the CSPF  
value shown in the following Table 2 and shall be marked onto the energy 
efficiency Labeling.  
(vi) Annual electricity consumption (kWh), which is the value of  the cooling seasonal 
electrical consumption (CSEC) calculated following  CNS 15712 -1; 
 3(vii) The year and announcement number of the Announcement containing the Criteria 
for Energy Efficiency Rating of Non-ducted A ir Conditioning Machines  used for 
this rating determination ; 
(viii) Registration number for this rating ; 
(ix) Other text as designated by the Central Competent Authority . 
(3) Display or post the label  
While displaying or marketing the products, the dealer shall  display or post the energy 
efficiency rating label on the front of the products, and shall  not hide, destroy or adopt 
other means to render the label not recognizable by the  consumers. While 
manufacturing or importing the products,  the dealer shall display the energy efficiency 
label in the product instruction/manual,  or place the label in a prominent area on the 
front of the products.  
(4) Energy efficiency rating  
After the aforementioned application has been approved by the Central Competent  
Authority, the dealer may download the energy efficiency rating label from the  
management system and start using the label.  
(5) Compliance inspection scheme  
In principle, the number of products first sampled and tested shall be decided  based on 
the sales volume  of the designated model number of the previous year, and  one sample 
shall be tested out of 10,000 units of such product model sold. If less than  10,000 units 
were sold for that model number in the prior year, one sample shall be  tested. 
Nonetheless, the Central Competent Authority may change the sampling ratio  based on 
actual ne eds.

Note： 
1. The minimum energy performance standard  requirements  apply to rated cooling 
capacity below 71kW.  
2. The air conditioners shall be tested according to CNS 3615, CNS 14464, and CNS 
15712 -1. 
3. Under T1 ambient test condition in CNS 14464, the rated cooling capacity, rated middle 
cooling, rated electrical power inpu t of cooling, and rated electrical power input of 
middle cooling shall be measured. Afterward, the cooling seasonal total load (CSTL) 
and the cooling seasonal electrical consumption (CSEC) shall be calculated by CNS 
15712 -1. 
4. The CSTL and CSEC with unit ‘kWh’ shall be calculate d to nearest integer number, 
and the CSPF is calculated to the second decimal point, the third decimal rounding.  
5. The value of CSPF calculated from the previous tested values shall not be less than the 
standard  value  specified in the ab ove table and be more than 95% of the marked value 
on products .
