    Xiaomi’s Latest Air Conditioner Hits the Chinese Market

    We have reported on Xiaomi air conditioners several times before. This product category appears to have become fairly important for the manufacturer, at least in its home market of China. At least some models have also made it to Europe. However, it remains unclear whether the Mijia Powerful Wind Floor-Standing Air Conditioner Ultra 3HP will do the same. In China, the model is offered for the equivalent of around $900. Its output is listed at 3 HP, while Xiaomi states a maximum cooling capacity of 37,500 BTU/h and a maximum heating capacity of 54,600 BTU/h. However, this does not correspond to electrical power consumption.

    Performance Metrics and Climate Adaptability

    Xiaomi lists an Annual Performance Factor of 4.90. In Germany, this value is referred to as the annual performance factor, although it is unclear whether it is determined under the same conditions. In theory, calculated over a full year, 1 kWh of electrical energy can generate 4.9 kWh of heating and cooling output. However, the actually achievable value also depends on factors including the absolute target temperature, the outside temperature, and the difference between the two. The model is said to be usable at outdoor temperatures between -31°F and 149°F, meaning even in very harsh winter conditions.

    Design and Airflow Capabilities

    The indoor unit is designed as a floor-standing appliance and is said to offer an airflow rate of 63,600 cubic feet per hour, with a range of up to 52 feet. This should allow even larger rooms to be brought to the desired temperature quickly with one indoor unit. The outlet angle is listed at 115°, which means the indoor unit can be positioned sensibly in a room corner, for example. The smart functions are not particularly surprising. Control via an app is supported, as is smart home integration. For example, the target temperature can be adjusted using voice commands.
