Portable split air conditioner Unold Esge 86340 — 12,000 BTU/h, cooling/heating/dehumidifying/ventilating, 57 dB, white
The Unold Esge 86340 portable split air conditioner offers up to 12,000 BTU/h of cooling capacity in a compact white plastic housing. Designed for temporary or mobile climate control, this unit integrates cooling, heating, dehumidifying and ventilating functions in a single appliance. With an energy efficiency class A+ for cooling and an operating noise level of approximately 57 dB, the Unold Esge 86340 aims to balance performance and everyday comfort in homes, offices and small commercial spaces.
The device provides four-mode operation—cooling, heating, dehumidifying and ventilating—so it can be used year-round for basic climate management. Its maximum cooling capacity of 12,000 BTU/h makes it suitable for moderating temperatures in medium-sized rooms. The A+ cooling efficiency class supports lower energy consumption compared with less efficient units, and the white plastic housing is lightweight and easy to position in temporary setups. The specified noise level of 57 dB indicates relatively quiet operation for a portable split system.
This portable split unit may not be appropriate for large open-plan areas or industrial spaces where higher cooling/heating capacities are required. It is also not intended as a permanent replacement for a central HVAC system; for whole-building climate control, a dedicated fixed system will be more effective. Noise and airflow characteristics of any portable unit may still be noticeable in very quiet environments.
Place the unit on a stable, level surface with sufficient clearance around the air intake and outlet to allow unrestricted airflow. Connect the unit to a properly rated electrical outlet and follow the manufacturer’s setup instructions for any external ventilation or split connection required. Select the desired operating mode—cooling, heating, dehumidifying or ventilating—and adjust fan speed and temperature settings as needed. Regularly clean or replace any filters and ensure condensate drainage or collection is managed according to the user manual to maintain performance.
For efficient operation, size the unit to the room and keep doors and windows closed while cooling or heating. Perform periodic filter maintenance and allow for adequate airflow clearance. Use dehumidifying mode to reduce indoor humidity before running intensive cooling to improve comfort and energy efficiency.

Rating of how efficiently a device uses energy, affecting power consumption and costs.
Not only energy saving helps to protect the environment but also noise level reduction. Noise level reduction up to 3 dB really means noise level reduction in 2 times. For example, a device with noise level 39 dB (А) will be two times quieter than a devise with a noise level 42 dB (А). Energy-saving certificate that shows noise level plays the role of an additional objective indicator basing on which You can successfully choose a product.
