The split system with a compact indoor unit design, Gree Cosmo GWH07AWAXA-K6DNA1B, is suitable for installation above doorways or in environments with limited space. The width of the indoor unit is 73.5 cm, with an installation depth of 19 cm.

The air conditioner uses inverter control, supported by the I Feel temperature sensor in the remote control. This sensor measures the temperature regime at the location of the remote, thus the split system more accurately tracks the microclimate parameters directly near the users. Optionally, the operation of the air conditioner can be managed via a smartphone, for which you'll need to acquire a separate Wi-Fi module.

An ozone-safe R32 refrigerant flows through the veins of the split system. The model can withstand extreme heat up to +50 °C and severe cold—for heating mode, the air conditioner can operate at outdoor temperatures down to -25 °C. Additional modes on board the Gree Cosmo GWH07AWAXA-K6DNA1B include dehumidifying and air ventilation.

A proprietary Cold Plasma generator is installed in the indoor unit of the air conditioner. The plasma ionizer fights viruses, harmful bacteria, and allergens while simultaneously saturating the air with negatively charged aeroions. These particles have a beneficial effect on the overall well-being of household members.

Hisense products occupy a very strong position in the budget and mid-segments of climate technology. The best practical confirmation of this is the Omega CF20YR0A inverter split system with a reliable brushless Toshiba GMCC motor.

The basic modification of the air conditioner is aimed at use in residential and office premises of about 20 m². In the hot summer heat, it provides the desired coolness, while in winter frosts down to -15 °C, it can work as the main or auxiliary heating source. Circulation of environmentally friendly R32 refrigerant is established through the duct between the split system units.

The indoor unit model is executed in an ascetic design without any frills, having a width of 79.5 cm. On the front panel of the indoor unit, there is a hidden info display showing the temperature and selected operating modes. The air conditioner is controlled using the included remote. By the way, the remote is equipped with an I FEEL temperature sensor, which helps to accurately sustain microclimate parameters right where the users are.

The split system is equipped with an ULTRA Hi Density fine filter and a deodorizer with activated charcoal to eliminate organic and household odors from the air. The charcoal filter is worth changing approximately once every six months. Additionally, the model features an "Anti-freezing" mode that maintains the temperature in an unheated room at around +8 °C to prevent severe wall freezing. This is good for country house use.

Seiya in Japanese means a quiet night. The Toshiba RAS-B07B2KVG-E/RAS-07B2AVG-E air conditioner from the eponymous line of climate equipment truly captivates with its silent operation in Silent mode (around 19 dB).

The inverter compressor guarantees low noise, and additionally ensures high accuracy in maintaining the target room temperature. The model has a nominal power of 7000 BTU and is intended for rooms with an area of about 20 m². The slim form-factor of the indoor unit with a width of 77 cm fits perfectly into confined spaces.

The air conditioner works for cooling (at outdoor air temperatures from -10 °C to +46 °C), for heating (from -10 °C to +24 °C), dehumidifies overly humid air masses, and operates in ventilation mode (without changing the temperature regime). The fine filter further removes dust and other contaminants from the air.

The model features automatic restart with pre-set settings, and optionally, you can connect a Wi-Fi module for remote control via mobile devices. The regular tool for setting the air conditioner's settings is a remote control with an LCD display and blue backlight.

The Japanese company Daikin holds a well-deserved reputation in the field of household and industrial climate equipment production. An affordable solution from the brand is the model FTXF20E/RXF20E from the economy line Sensira.

The air conditioner is designed for small spaces—approximately up to 20 m². It operates under an inverter compressor, smoothly adjusting power in accordance with the current temperature inside the room. As a result, the split system operates economically and ensures high precision in maintaining set microclimate parameters.

The model works for cooling at outdoor air temperatures up to +48 °C, and for heating down to -15 °C. Meanwhile, the air conditioner can dehumidify overly moist air and operates in ventilation mode. Air passage cleaning is provided by the HEPA filter inside the indoor unit, which traps even the smallest pollution particles.

The indoor unit of the split-system features reduced dimensions in width—neat 77 cm. A Daikin Residential Controller Wi-Fi module is offered as an option, sold separately. Using this wireless connectivity adapter, remote management of the air conditioner’s operation can be organized via smartphone or tablet.

The wall-mounted split-system Panasonic CS-TZ20ZKEW/CU-TZ20ZKE from the household air conditioners family Compact has interior unit dimensions of 77.9 cm in width. This allows placing the air conditioner above a doorway.

The model uses the Aerowings airflow system, directing air streams to the ceiling to create a "cold shower" effect and consequently, quicker room cooling. The air conditioner also supports heating operation at outdoor air temperatures down to -15 °C. Other modes include air mass dehumidification and ventilation.

An inverter drive is at the helm of the split-system. Its operation can be controlled via a remote control or paired mobile devices (through Wi-Fi). The Panasonic Comfort Cloud app is used for remote settings operation, and the model also understands voice commands through Google Assistant and Amazon Alexa assistants.

Air purification issues are handled by the proprietary nanoe X filtration system with hydroxyl radicals. It destroys viruses, fungi, and harmful microorganisms both in airflow and on surface objects in the serviced area (be it soft furnishings or hard surfaces). The model costs slightly more than compact counterparts, but with its collective qualities, it is certainly worthy of close consideration.
