The Samsung AC100RNMDKG is a duct-type indoor air conditioning unit designed to manage the climate of large spaces up to 100 m². It provides both cooling and heating, utilizing inverter technology and a Twin Rotary BLDC compressor to maintain efficiency. With a cooling capacity of 36,000 BTU/h (10 kW) and a heating capacity of 11.2 kW, this system is capable of operating in extreme outdoor conditions, from -20 °C in winter to 50 °C in summer. Its Slim Fit design keeps the unit compact with a height of 25 cm and a weight of 34 kg, making it easier to integrate into ceiling voids. The internal airflow is managed by a DC motor and a Sirocco fan with aerodynamic blades, which helps keep the maximum noise level down to 30 dB for a quieter indoor environment. To ensure consistent performance, the Auto ESP feature automatically adjusts the external static pressure to optimize air volume. Maintenance is simplified through a Slide Fit cover that allows service access from the top, side, and bottom. This unit uses R-32 refrigerant and belongs to the A+ energy efficiency class, supporting a maximum pipe length of 50 m when paired with the compatible AC100RXADKG/EU outdoor unit.
