The ACSON VIENTO series is an R32 refrigerant-based inverter air conditioner available in various capacities ranging from 1.0HP to 2.5HP. Being an inverter type, it offers energy-efficient cooling by adjusting the compressor speed to match the cooling demand, leading to reduced electricity consumption and quieter operation. The use of R32 refrigerant contributes to a lower global warming potential compared to older refrigerants, making it a more environmentally friendly option.
