Inverter Air Conditioner ARIELLI ACSD-12DB (WI-FI)
Description
12,000 BTU.
Smart control.
An inverter wall-mounted air conditioner with A++ cooling, A+++ heating and R32 refrigerant — for rooms of roughly 25 to 35 m².
It does not switch on and off. It simply holds.
A conventional air conditioner runs at full power until it reaches the set point, stops, waits for the room to drift and then starts again at full power. Every such start is a current spike and a noticeable change in the room.
The inverter in the ACSD-12DB adjusts the compressor speed smoothly. Once it reaches the temperature, it does not stop — it simply slows down and runs at exactly the rate the room loses heat. That gives all three effects at once: a more stable temperature, lower consumption and less compressor wear.
A++ for cooling, A+++ for heating
SEER 6.1 means that for every kilowatt-hour of electricity the air conditioner returns over six kilowatt-hours of cooling, measured across the whole season — not at an ideal point, but with partial loads and standby mode included.
In heating, SCOP is 4.0 for an average European season. In a warmer climate the same unit records SCOP 5.1 and reaches class A+++ — which in practice means that along the Black Sea coast and in southern Bulgaria the real efficiency is higher than the label.
The room is ready before you walk in
The built-in Wi-Fi control connects the air conditioner to an app on your phone. From there you set the temperature, mode and timer — from the office, from the car, from the other end of the country.
The most practical use is the simplest one: you switch it on twenty minutes before you get home, instead of waiting for the room to even out once you are already inside.
R32 — less refrigerant, a smaller footprint
The ACSD-12DB runs on R32. Compared with the widely used R410A it has around three times lower global warming potential and a higher volumetric cooling capacity — that is, the same job is done with less refrigerant in the system.
Work on the refrigerant circuit is carried out only by a licensed technician. The unit must not be disassembled by yourself.
Inverter compressor
Smooth speed regulation instead of start-stop cycles — a stable temperature and lower consumption.
Wi-Fi control
Temperature, mode and timer from a smartphone — anywhere, any time.
R32 refrigerant
GWP 675 — around three times lower impact than R410A, with higher efficiency.
Heating and cooling
12,000 BTU in both directions — one unit covers both summer and the transitional seasons.
Quiet operation
Up to 44 dB(A) at the indoor unit — a level that disappears into the background noise of a home.
5-year warranty
A 60-month warranty with service support for Bulgaria from Magnum-D EOOD.
What room this model is for
12,000 BTU (3.5 kW) cover a typical living room or a large bedroom in a home with standard insulation and a ceiling height of up to 2.7 m. This is a guide value — with a lot of south-facing glass, a top floor or poor insulation, a larger capacity is chosen. For an exact choice, use an on-site survey by a technician.
