Mitsubishi Electric MSZ-GS09VF 1HP Inverter Cooling and Heating Split Air Conditioner

The Mitsubishi Electric MSZ-GS09VF is a 1 HP R32 inverter heat pump (cooling and heating) split air conditioner with an indoor unit noise level as low as 21dB(A). One unit handles cooling in summer and heating in winter, suiting users who need to regulate room temperature all year round.

3.20kW heating capacity, annual heating energy consumption of 26kWh

Its heating capacity is higher than its 2.55kW cooling capacity; the rated power input when heating is 0.76kW, and the coefficient of performance (COP) reaches 4.21.

According to EMSD records, this model carries a Grade 1 energy label for both cooling and heating, with annual cooling energy consumption of 211kWh, and cooling and heating seasonal performance factors (CSPF and HSPF) of 6.0965 and 5.2989 respectively. Inverter control saves more energy than a fixed-speed air conditioner, helping to cut electricity costs.

The 3/4 HP cooling and heating MSZ-GS07VF in the same series has a heating capacity of 2.30kW, so this model's heating capacity is higher. The 1 HP cooling-only MSY-GS09VF has the same cooling capacity and unit sizes as this model but no heating; users who need heating in winter can choose this model.

Dual Barrier Coating and Easy Clean design reduce dirt build-up in the indoor unit

The heat exchanger, fan and air duct surfaces of the indoor unit carry a Dual Barrier Coating, which combines fluoride particles with a hydrophilic film to effectively resist dust, fibre lint, cooking fumes and cigarette smoke sticking to them. With less dirt building up, the air conditioner helps deliver fresher air and also helps save energy.

The Easy Clean design lets you easily remove the main parts of the indoor unit and clear the dust inside yourself. Cleaning helps keep airflow normal and lowers the chance of bacteria growing.

The built-in anti-mould filter traps airborne dust and inhibits mould growth. Clean the filter regularly with a vacuum cleaner, or wash it in water and dry it in a cool, shaded place, and it can then be reused.

To improve indoor air quality further, optional filters are sold separately: a particle-capturing filter or an electrostatic antibacterial enzyme filter. The former uses static electricity to attract PM2.5 fine suspended particles in the air, while the latter can adsorb allergens and inhibit viruses and bacteria.

Indoor unit as low as 21dB(A), with Sleep Mode adjusting the temperature for sleep automatically

According to Mitsubishi Electric, the operating noise of the indoor unit is below the 25dB quiet standard for recording studios, so it stays quiet when switched on at night.

Switch on Sleep Mode before bed and, whether cooling or heating, the room temperature adjusts automatically to a temperature suited to sleeping, then returns to the original setting after about 2 hours; the airflow direction can also be adjusted to your preference. The 24-hour preset on/off timer can be matched to your bedtime, the time you arrive home or the time you get up, setting the unit to switch on and off in advance to help save energy.

Fast Cooling mode lasts 15 minutes, delivering cool air at the press of a button

On hot days, switch on Fast Cooling mode and the compressor runs rapidly, operating with high airflow and low temperature so you feel cool quickly.

Up/down airflow swings automatically, while left/right airflow direction is adjusted manually. In humid weather, you can switch on independent computer-controlled dehumidification during cooling (0.63L per hour) to reduce indoor humidity.

Outdoor unit 730 x 420mm (W x H), suitable for most air conditioner window-ledge installations

The drain tray channels condensate into the base pan of the outdoor unit, effectively reducing leaks; the drain nozzle angle is adjustable, so connecting a drain hose carries the condensate away and lowers the risk of flooding. The body has an anti-corrosion blue coating, together with a rust-proof oil-treated casing and a galvanised steel base pan, to reduce corrosion of the outdoor unit.

Refrigerant piping can be up to 20m long, with a height difference of up to 12m between the indoor and outdoor units, making it convenient to position the two units to suit the layout of your home. The circuit board has a protective coating that guards against damp and insects damaging components and withstands voltages of up to 450V; even when the voltage is between 198V and 242V, the inverter keeps running smoothly.
