General ASWX09CECA 1 HP R32 Full DC Inverter Cooling-only Window Split Air Conditioner

General ASWX09CECA is a 1 HP cooling-only window split air conditioner with a recommended room size of 90 to 110 sq ft, suited to bedrooms or studies. The outdoor unit is only 368mm high, fits window ledges, and is also shallower than the same brand's 1 HP window unit.

Outdoor unit 150mm shallower than the same brand's 1 HP window unit

The same brand's 1 HP inverter window unit AKWB9NID measures 450 x 350 x 640mm (W x H x D), while this outdoor unit measures 500 x 368 x 490mm, so it takes up less window ledge depth once installed. However, the outdoor unit is 50mm wider and 18mm taller, so measure the width and height of the window opening before installing. Installation is easy and, depending on the actual situation, scaffolding may not be needed.

2.65kW cooling capacity, recommended for 90 to 110 sq ft

The recommended range is an initial reference only. Occupancy, sunlight and insulation all affect the cooling actually needed. Rooms facing west, on a top floor or often used by many people may need higher cooling capacity, so assess your actual conditions before buying.

When you need the room cooled quickly, switch on powerful mode, which runs at maximum output and the strongest airflow and switches off automatically after 20 minutes or when the room reaches the set temperature.

This air conditioner holds an EMSD Grade 1 energy label, with annual cooling energy consumption of 248kWh, which you can use to compare power use with other air conditioners. Energy-saving mode limits maximum output to about 70% of normal operation to reduce power consumption.

Indoor unit quiet mode only 21dB(A)

The indoor unit has 5 fan speeds, with high at 43dB(A). Switch to quiet mode when going to sleep, suited to bedrooms at night.

With outdoor unit quiet operation on, the compressor speed is reduced and the fan runs slower. Cooling capacity falls as a result, but outdoor unit noise is reduced.

The sleep timer can be set from 30 minutes to 9 hours, gradually easing off the air conditioner during that time so you sleep comfortably. The on/off timer lets you preset the switch-on and switch-off times within 24 hours to suit your daily routine.

7 up-down airflow positions, triple filters remove dust and odours

The horizontal louvre has 7 positions and swings up and down automatically when cooling; left-right airflow is adjusted by hand. Auto airflow adjustment lets the computer regulate airflow according to room temperature changes, so you need not adjust it manually each time; the auto open/close louvre closes when the unit stops and opens when it starts.

Of the triple filters (antibacterial, apple catechin and negative-ion deodorising), the apple catechin filter removes fine particles and dust from the air by static electricity, while the negative-ion deodorising filter uses ceramic to release ions that break down odours absorbed on the filter. The panel can be removed for washing, making day-to-day care easy.

In humid weather, switch to independent dehumidifying mode, which runs at low fan speed to regulate room humidity. After a power cut, the air conditioner restarts automatically in its previous mode when power returns. The remote control is backlit, so it is easy to use with the lights off.
