(3) In case the model of the tested product in the energy efficiency 
test report differs from the one applied for e nergy efficiency 
grade labelling yet belongs to the product of the same basic 
model  product , the application shall be accompanied with 
energy efficiency conformity declaration ( see Appendix 4).  
The energy efficiency test report under subsection 2 of the pr eceding 
paragraph shall be written down  that conditions adjusted  in 
accordance with  the CNS 12575 , and issued by the laboratory that 
was certified by the CCA or certification authorities. The certification 
authority is members to the mutual recognition agr eement signed by 
the Taiwan Accreditation Foundation (TAF) or the International 
Laboratory Accreditation Cooperation (ILAC).  
The product of the same basic model under subsection 3 of the 
Paragraph 1  shall be made up of the same key components referred t o 
Appendix 3 . 
5. The CCA shall approve the energy efficiency grade and registration 
number of the product based on the chiller’s energy efficiency grade 
table ( see Appendix 5) according to the rated COP and refrigeration 
capacity value given in the energy effic iency test report.  
 6. When manufacturing or importing the chiller for domestic use, the 
dealer shall reapply for the registration for the energy efficiency 
rating and registration number in the following instances : 
(1) The key componen ts of the product have  been changed  
(2) The model of the product has been changed.  
(3) The CCA had amend regulation for the minimum energy 
performance standard ( see Appendix 1), the energy efficiency 
rating ( see Appendix 5), the energy efficiency grade label ( see 
Figure 1) or presentation  (see Figure 2) of the chiller.  
 
7. While manufacturing or importing the approved product for 
domestic use, the dealer shall register at the Management System and 
download the management serial number which shall be marked on 
the nameplate.  8. Before manufactu ring or importing the product for domestic sale and 
use, the dealer shall mark the following items on a nameplate and 
fixed the front and visible position of the product.  
(1) Type of the product.  
(2) Name, telephone number and address of the manufacturer, and 
in the case of imported, the importer name, telephone number, 
address.  
(3) Model of the product.  
(4) Date of manufacture.  
(5) Serial number of  manufacture.  
(6) Nominal voltage, phase, and frequency.  
(7) Registration number of the product.  
(8) Management serial number of the product.  
(9) Nominal refrigeration capacity at full load of the product (kW).  
(10) Nominal total input power at full load of the product (kW).  
(11) Nominal  COP . 
(12) Energy efficiency grade . 
The above items shall all be labeled in Mandarin Chinese, except for 
unit symbols or special characters, and cannot be concealed, 
destroyed or rendered otherwise unrecognized.  
9. The dealer  shall have the energy efficiency grade label ( see Figure 
1) attached to the front and visible position of the product  or noted 
in the manual included with the pr oduct.  10. The dealer shall have graph of the product contained in catalog used 
for merchandising or selling it explicitly accompanied by its energy 
efficiency grade presentation (see Figure 2). Information of the 
product presented in text or table shall be a dded with COP rated 
value and energy efficiency grade.  
11. The CCA may run random tests for energy efficiency checks before 
approve the energy efficiency grade or  before  the dealer obtain s the 
management serial number. The dealer shall deliver products of 
specified by the CCA to given lab oratorie s before given date, and the 
CCA may send staffs or professional institutions to inspect the 
procedure and method of test.  
While failed the random test under the preceding paragraph, the CCA 
shall revoke the energy eff iciency grade and registration number 
certification, and subject dealers to the Clause 21 and 24 of the 
Energy Administration Act.  
The dealer shall pay the bill of the random test mentioned  above.  
12. While manufacturing or importing the product which meeti ng the 
definition in CNS 12575 -2007 of the heat recovery chiller, the dealer

recovery chiller.  
 13. For the approved product meeti ng the definition in CNS 12575 -2007

announcement. Products also may be free from the Labeling item 9 
to 12 of section 8  in this announcement.  Appendix 1

Note:  
1. The coefficient of performance (COP) of the chiller shall be tested according to the 
CNS 12575 -2007 at fouling f actor equal zero and full load conditions, and obtained 
by dividing the tested total input power into refrigeration capacity.  Round the COP 
calculation to two decimal places, which shall be not lower  than minimum energy 
performance standard requirements.  
2. The value of nominal COP shall be not lower than minimum energy performance 
standard requirements.  
3. The products meeting the definition in CNS 12575 -2007 of the heat recovery chiller 
and approved by the CCA, which shall not be subject to this restriction.  Appendix 2
