IR123TSN Specifications, Features & Compatibility Guide
IR123TSN 1 Ton Inverter AC provides 3500W cooling, ideal for small Indian rooms up to 130 sq ft. Flexi 5 mode handles 55°C peaks using 689.19 kWh yearly. Copper condensers ensure durability with a 3.93 ISEER rating.
Quick Answer
Yes, the IR123TSN is an excellent choice if you need efficient cooling for a room between 90-130 sq.ft. Its BEE 2023 3 Star rating and ISEER of 3.93 mean significant long-term savings on your electricity bills, making it a wise investment for sustained comfort. The FLEXI 5 Convertible mode further adds adaptability, ensuring optimal performance across varying heat loads in the Indian climate.
Opt for the IR123TSN if you seek a cost-efficient cooling solution for rooms up to 130 sq.ft, valuing long-term energy savings over initial outlay. However, if your space exceeds this capacity or you prioritize ultra-low capital expenditure, explore other options as this 1 Ton 3 Star model is optimized for its rated efficiency and area.
✓ Who Should Buy

Engineering Analysis
Energy performance of the IR123TSN is anchored by its BEE 2023 3 Star certification and an ISEER of 3.93. Under standardised BEE test cycles, annual consumption is 689.19 kWh per year — competitive long-term operational cost over a 5-year ownership horizon. The Rotary employs Variable Frequency Drive (VFD) control, modulating compressor RPM continuously between 15 Hz and 120 Hz to match real-time thermal load — eliminating the energy-intensive stop-start cycles of fixed-speed motors. Peak electrical draw is 1100W at 220-240V nominal supply, with an inverter drive board maintaining power factor above 0.95 across all load states.
The IR123TSN is built around 100% copper condenser coils, which outperform aluminium alternatives with 40% higher corrosion resistance — a critical durability metric for India's coastal zones, humid interiors, and regions with salt-laden particulate air. Copper's superior thermal conductivity (401 W/m·K vs aluminium's 205 W/m·K) means heat rejection is faster and more complete, directly preserving the rated ISEER across the product lifespan. R32 refrigerant carries a Global Warming Potential of 675 — 68% lower than R410A (GWP 2088) — requiring 30% less charge by weight, reducing both refrigerant leak risk and total lifecycle environmental load. Multi-stage filtration (Anti-bacterial) captures PM2.5 particulates, volatile organic compounds, and microbial contaminants — delivering measurably healthier indoor air beyond raw temperature control. 2-Way motorised air distribution directs conditioned air uniformly across the room throw envelope, eliminating thermal stratification and hot-spot buildup. The 5 years compressor warranty signals the manufacturer's projected confidence in mechanical durability under India's sustained 10–12 hour daily summer load patterns.
Standard power management rated at 220-240V ensures safe operation. Auto-restart with non-volatile memory ensures the IR123TSN resumes at the last-set temperature and mode after power interruption — a functional reliability requirement for Indian grid zones experiencing 4–10 daily outages during peak summer months. Validated for 55°C maximum ambient operation — 7–9°C above the IEC 60335-2-40 standard test baseline of 43°C — the hardware thermal management stack is certified for India's harshest summer regions including Rajasthan, Vidarbha, coastal Andhra Pradesh, and the Gangetic plains.
