Air conditioner Nobus Inverter R32 18000 BTU

The Nobus Inverter R32 18000 BTU air conditioner is a high-performance wall-mounted split system designed for spacious residential, administrative, and commercial premises. The model is intended for an approximate area of up to 50 m² and is suitable for a large living room, open-plan apartment, private house, office, shop, beauty salon, classroom, or small conference room.

The cooling capacity is 5.1 kW, while the heating capacity reaches 5.2 kW. This enables the system to change the air temperature quickly and maintain comfortable conditions even during extended daily operation. The A+ energy efficiency rating and inverter control help match electricity consumption to the actual load. 

High performance for areas up to 50 m²

A capacity of 18000 BTU is suitable for spaces where a compact 9000 or 12000 BTU model may not be sufficient. The air conditioner provides an airflow of up to 850 m³/h, allowing cooled or heated air to spread more quickly throughout a spacious room.

The model can be installed in a combined kitchen and living area, an open-plan office, a retail space, or another room with a large volume of air. For efficient operation, the indoor unit must be positioned correctly: wardrobes, partitions, heavy curtains, and other tall objects should not obstruct the airflow.

The stated coverage area of up to 50 m² is approximate. Capacity requirements are affected by ceiling height, window size, insulation quality, exposure to sunlight, the number of occupants, and the presence of heat-generating equipment. Additional capacity should be considered for rooms with panoramic glazing or frequently opened doors.

Inverter technology and stable temperature

The inverter compressor automatically changes its operating intensity according to the current temperature. Initially, the air conditioner uses the required power to cool or heat the room quickly. Once the set temperature has been reached, it switches to a maintenance mode.

This control method reduces sudden temperature fluctuations and repeated compressor start-ups. As a result, the system maintains a more consistent indoor climate while using electricity efficiently. The nominal power consumption in both cooling and heating modes is approximately 1.4 kW.

Inverter technology is especially convenient for offices, shops, and residential spaces where the air conditioner operates for several consecutive hours. The user does not need to switch the unit on and off repeatedly, as the system automatically adapts its capacity to changing heat loads.

Comfort in hot and cool weather

The Nobus Inverter R32 18000 BTU supports cooling, heating, dehumidification, and ventilation modes. In summer, the split system helps reduce the temperature quickly in a spacious room. In heating mode, the air conditioner can be used as an additional heat source during transitional seasons and at outdoor temperatures down to −15 °C.

The dehumidification function reduces excess moisture without overcooling the air. This mode is useful on rainy days, in rooms with insufficient ventilation, or whenever the space feels damp. Ventilation mode circulates the air without actively changing its temperature.

The indoor unit has a noise level ranging from 30 to 47 dB, depending on the selected fan speed. A special mode is available for evening and nighttime use, helping create quieter and more comfortable conditions for rest.

Convenient settings and optional Wi‑Fi connectivity

The remote control allows users to select the operating mode, set the desired temperature, and adjust the fan speed. The on/off timer makes it possible to prepare a convenient schedule in advance—for example, cooling an office before the working day begins or automatically switching the system off in the evening.

The air conditioner comes in a Wi‑Fi Ready configuration. A compatible Wi‑Fi module must be purchased and installed separately for remote control through a mobile application. Once connected, users can adjust the main settings from a smartphone while at home, in the office, or on the move.

The model supports a refrigerant line length of up to 25 metres and an elevation difference of up to 10 metres between the units. These specifications provide greater installation flexibility in apartments, private houses, and commercial premises with complex layouts.

New-generation R32 refrigerant

The system uses R32 refrigerant, which offers efficient thermophysical properties. Compared with R410A, it has a lower global warming potential and is widely used in modern climate-control equipment. R32 supports efficient heat transfer when cooling and heating the room.
