The Hitachi Shizuka Series 1.5 Ton 3 Star Inverter Window AC (Model RAW318HHEO) combines high efficiency, comfort, and durability to suit Indian weather and usage patterns. Designed for medium-sized rooms (~150-200 sq ft), this unit uses inverter compressor technology to adjust cooling output according to real-time conditions, which helps reduce power consumption and stabilises temperature more smoothly than fixed-speed ACs.

It features a 100% copper condenser coil for faster heat exchange and better resistance to corrosion than aluminum. The R-32 refrigerant used is eco-friendly, lowering environmental impact. The AC works at high ambient temperatures, delivering full cooling even up to ~43 °C.

On the usability side, it includes features like:

• a wireless LCD remote for easy control,
• auto-restart (restores the last settings after power outages),
• filter clean indicator to maintain air quality,
• auto fan speed for adapting to cooling needs, and
• precoated aluminum / SuperSlit fins with anti-corrosive treatments for durability.

Noise levels are acceptable for a window AC of this capacity (~54 dB). Overall, it’s a well-rounded AC for those wanting energy savings, reliability, and decent features without paying the premium of higher star ratings.
