The_King Posted December 23, 2022 Share Posted December 23, 2022 (edited) Anyone know why 2 AC both are rated at 18kbtu one use more energy then another? Daikin: RKM50PVMG use 2646kWh ME: MUY-GP18VF use 2050kWh While System 2 >18k (with 1 fan coil instail and both match the btu with the condensor)use less energy as compare to system 1 18k btu? Daikin: MKM50VVMG use 1553kWh ME: MXY-2H20VF use 1664kWh is there someone wrong with the way i calculate or newer R32 model save more energy as compare old gen of R32 model. thanks sauce: https://e-services.nea.gov.sg/els/Pages/Search/PublicSearchProduct.aspx?param=goods&type=p Edited December 23, 2022 by The_King Link to comment Share on other sites More sharing options...
