Panasonic CW-SU120AA 1.5 HP Inverter LITE Cooling-Only Window Air Conditioner

The Panasonic CW-SU120AA is a 1.5 HP cooling-only inverter window air conditioner from the Inverter LITE series, delivering 12,200 Btu/h of cooling. Its 560 mm wide, right-outlet body comes with automatic left-right swing, a wireless remote control, and sleep, quiet and independent dehumidifying modes, for users who need more cooling capacity but want to keep the all-in-one installation of a window unit.

Right-side airflow with automatic swing for everyday seating

Viewed from the front indoors, cool air leaves from the right side of the unit. When the window, bed, desk or large furniture is already in place, where the airflow starts affects where it goes, so consider the 560 mm body width, the window position and your usual seating together before buying.

Horizontal airflow can swing automatically or stay fixed, while the vertical angle is adjusted by hand. This lets you direct air sideways to suit where people sit and avoid cold air blowing on one spot for long periods. Keep the area in front of the outlet clear of curtains and furniture.

12,200 Btu/h inverter cooling with a Grade 1 Hong Kong energy label

The CW-SU120AA uses inverter operation to adjust cooling output as needed, keeping the room at a steadier temperature once it nears the set point, and uses R32 refrigerant. Annual cooling energy consumption is 391 kWh, based on 1,200 hours of use a year. This is a useful figure for comparing the seasonal efficiency of similar models; actual consumption varies with conditions and settings.

Afternoon west sun, high ceilings, the number of occupants and connected spaces also affect the cooling capacity you need, so consider them together with room size when choosing.

Powerful, quiet, sleep and dehumidifying modes for daily needs

When the room is hot to begin with, POWERFUL mode raises the airflow to cool it down faster and returns to your original settings after up to 4 hours. Higher airflow may make the unit louder; choose QUIET mode when you want less airflow noise.

Sleep mode adjusts temperature and fan speed automatically to reduce overcooling after you fall asleep, with the system controlling both settings while it runs. Independent dehumidifying lowers indoor humidity with gentler cooling. The wireless remote lets you change temperature, fan speed and mode from your seat, and set either an on-timer or an off-timer.

Blue Fin Condenser and filtration for long-term use

The Blue Fin Condenser has an anti-rust, anti-corrosion blue coating that shields it from moisture and oxygen in the air, slowing oxidation and rust and helping it last longer. A 4-in-1 antibacterial filter is fitted; cleaning the air filter regularly reduces dust build-up that can restrict airflow and affect cooling performance.

560 mm wide body with a 15A plug and manufacturer's warranty

The unit measures 560 x 346 x 655 mm (W x H x D), weighs 39 kg net, and runs on 220V with a 15A three-pin round plug. Installation should be carried out by a qualified technician, who needs to check the opening, support, outdoor heat dissipation, airflow, drainage, a dedicated air-conditioner circuit and earthing; the body dimensions cannot be used directly as the opening size or full clearance. The product comes with a 3-year full-unit and 5-year compressor warranty.
