The calculations shall be performed as per clause 6, unless specified differently in this clause.  
F.2.2. Defined cooling load  
The defined cooling load 𝐿𝑐(𝑡𝑗) at outdoor temperature  𝑡𝑗 shall be determined by Formula (2) .  
In Formula (2), 𝑡0=20 and 𝑡100=46. 
In case of setting other cooling load, refer to the setting method as described in Annex D.  
F.2.3. Outdoor temperature bin distribution for cooling  
Cooling seasonal performance factor ( CSPF ) for T3 climate  shall be calculated at the reference 
climate condition in Table F.2 . 
The calculation of cooling seasonal performance factor may also be done for other climate 
conditions using different bin distribu tion under hot climate conditions.
