Engineering Note — Why MHI Exceeds BEE 2026

BEE tightened the 5-star threshold to ISEER 5.60 in 2026. Many ACs that were 5-star in 2024 are now only 4-star. The SRK18YXS-W6 at ISEER 5.80 remains comfortably above the new bar — not by luck, but because MHI engineers the 3D Auto Airflow system to reduce compressor runtime, not just peak BTU capacity. This is a fundamentally different efficiency philosophy from brands that chase ISEER through compressor spec alone.
