Climate Impact of Finalists’ Prototypes and Baseline AC Units
Hourly snapshot of prototype performance during the field test in Bahadurgarh, India
Gray bar indicates unit is failing to meet required indoor conditions of 27 degree Celsius and 60% relative humidity after allowing for sensor uncertainty
* Fixed-speed, mini-split type RAC unit with an Indian Seasonal Energy Efficiency Ratio (ISEER) of 3.5 W/W and using R22 refrigerant - representative of the most commonly sold RACs in the Indian market in 2018
** Climate impact of a prototype is determined by combining electricity reduction (kWh) and refrigerant GWP reduction, using assigned weighting of 80:20 respectively, relative to the baseline unit.
*** The climate impact range of the commercially best available technology is determined by combining electricity reduction (as implied by published ISEER ratings) and refrigerant GWP using assigned weighting of 80:20 respectively, relative to the operating conditions maintained by baseline unit #2.
Indoor temperature below 20 degree Celsius is outside the minimum threshold for assessment and reporting.
