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 efficiency 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 te st mentioned  above.

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
