This listing offers two types of Hisense air conditioners: an R32 Inverter model (AI10KAGS1) and R32 Non-Inverter models (AN10DBG/AN13DBG1). Both use the R32 refrigerant, known for its lower environmental impact. The inverter model (AI10KAGS1) provides energy-efficient cooling with variable compressor speed, leading to lower electricity consumption and consistent temperature. The non-inverter models (AN10DBG and AN13DBG1) offer a more budget-friendly option for cooling with fixed compressor speed, suitable for smaller rooms. Both Inverter and non-inverter models are available in 1HP and 1.5HP configurations, suitable for different room sizes.
