The Samsung WindFree Premium Plus is an inverter air conditioner that uses R32 refrigerant, available in 1HP, 1.5HP, 2HP, and 2.5HP models. Its key feature is the WindFree cooling technology, which disperses air gently through thousands of micro-holes, eliminating unpleasant drafts while maintaining a consistent temperature. The inverter technology ensures energy efficiency and quieter operation compared to traditional air conditioners. It provides effective cooling while minimizing energy consumption and maintaining a comfortable environment.
