According to Tab.6.8.1I for test procedure for VRF systems we have to consider AHRI 1230. I’m considering AHRI 1230 version “Approved by ANSI on 2 August 2010”. As for heating for machines > 19kW, two different conditions are specified:
- Standard Rating Conditions (high temperature steady state heating): outdoor section, air cooled DB/WB 8.3/6.1°C
- Standard Rating Conditions (low temperature steady state heating): outdoor section, air cooled DB/WB -8.3/-9.4°C
Which one shall be considered in order to verify the compliance with Tab. 6.8.1I?
