(*) 1 cluster or 2 cluster air conditioners: the energy efficiency of the equipment is evaluated by the Cooling Seasonal Performance Factor (CSPF) instead of the Coefficient of Performance. The process of testing and evaluating the equipment's energy efficiency is carried out per TCVN 7830:2015, TCVN 6576:2013 and TCVN 10273-1:2013 (ISO 5151:2000).
