Air conditioner 7.9 kW multi-split outdoor unit MU LG MU4R27.U42

LG MU4R27.U42 multisplit air conditioner is an advanced solution for comfortable cooling and heating, designed for both demanding end-users and professional installers. The unit allows connection of up to four indoor units, offering flexibility in designing air conditioning systems in residential and commercial buildings.

Performance and energy efficiency

This model stands out with a high cooling capacity of 7.9 kW and a heating capacity of 9.1 kW. Thanks to the use of inverter control technology, the air conditioner adjusts its operation to current needs, which translates into energy savings. Energy class A++ in cooling mode and A+ in heating mode guarantees low operating costs. SEER (8) and SCOP (4.2) coefficients confirm the high efficiency of the device. The use of R32 refrigerant is another step towards ecology – it is more environmentally friendly than older generations of refrigerants.

Construction and application

The MU4R27.U42 outdoor unit is characterized by a solid construction and compact dimensions (950 mm height, 835 mm width and 330 mm depth), which facilitates installation even in limited spaces. The weight of the device is 61 kg. It is designed to work with various types of indoor units – wall-mounted, cassette or ducted – allowing you to tailor the system to individual needs and preferences. The compressor and BLDC fan motor ensures quiet operation of the device, and the quiet night operation function further minimizes noise levels (sound pressure level for cooling is 50 dB(A), and for heating 54 dB(A)).

Additional functions and safety

The LG MU4R27.U42 air conditioner has a number of functions that increase comfort and installation safety. Variable voltage control ensures stable operation of the device, and optimization of refrigerant distribution guarantees efficient operation of the entire system. Additionally, the unit has a work mode lock (cooling or heating) and a forced cooling mode function. The Black Fin anti-corrosion coated condenser ensures the durability of the device even in harsh weather conditions. It is important to remember the need for installation by a qualified installer with F-GAS qualifications and compliance with regulations regarding the handling of equipment containing fluorinated greenhouse gases.
