What is multi-split air conditioning?

Air conditioning and air conditioners are most often associated with comfort and practicality. However, it is worth knowing that thanks to the use of air conditioners LG multi-split air conditioning it can also be stylish and elegant. Multi-split solution allows you to operate multiple rooms using only one outdoor unit. How does it look in practice? It is installed outside the building one external device and you can successfully connect to it up to five indoor units. It significantly increases it the aesthetics of the building without having to give up the comfort of cooling or heating inside.

Advantages of the multi-split system

Multi split system is the solution aesthetic, elegant and comfortable. Significantly reduces the area occupied by external air conditioning elements. Thus, it improves the aesthetics of the building and allows it to be effective cool from 2 to even 5 rooms using independent indoor units. It is also worth noting that the indoor units do not have to be the same model. Moreover, they might as well be wall, cassette, duct, ceiling and console devices. There are no restrictions in this regard and their power or appearance can be strictly dictated by the needs of users.

Who decides on a multi-split system?

This solution is often chosen by companies where employees occupy several office rooms. Thanks to this, each room gains effective cooling and the installation of external elements is much easier. This solution will also work wherever the building manager decides on the possibility of installing an external air-conditioning element and allows only one for a given premises - for example in apartments. WITH multi-split solution you no longer have to decide which room will be air-conditioned. external device in multi-split system od LG will serve until 5 indoor units. Also in single-family homes multi-split air conditioning it will work perfectly, providing both cooling and heating, depending on your needs.

MULTI models MU2R15 and MU2R17 are one of the most frequently and most frequently chosen devices among outdoor units. They are perfect for combination with multi-split air conditioning. They provide both cooling and space heating when connected two indoor units. Outdoor units LG MULTI MU2R15 and MU2R17 are driven by brushless direct current (BLDC) motors. Such a drive increases the efficiency of the device, which is extremely important during the peak operation. Model MULTI MU2R15 has a cooling capacity of 4,1 kW and a heating capacity of 4,7 kW. Whereas the unit MULTI MU2R17 has a cooling capacity of 4,7 kW and a heating capacity of 5,3 kW.

Innovation from LG

W LG MULTI MU2R15 and MU2R17 a number of innovative solutions have also been used to extend its life, minimize the frequency of servicing and less frequent use of the unit defrost cycle. These solutions include, among others twin rotary inverter compressor, Wide Louver Plus slats, goldfin coating heat exchanger. Thanks to them, the heat exchanger gets rid of water faster and frosts up slower. Thus, the period between defrost cycles is much longer. In addition air conditioner automatically regulates the pressure of the refrigerant depending on the ambient temperature. This has a direct impact on its energy efficiency without losing thermal comfort in the rooms.

Features of LG MULTI MU3R19 and MU3R21 units

MULTI MU3R19 and MU3R21 are efficient and energy-saving outdoor units intended for use in multi-split system. LG MULTI MU3R19 and MU3R21 external devices provide effective and efficient heating and cooling. In addition MULTI outdoor units MU3R19 and MU3R21 are devices energy saving. In addition, their appearance is subtle and delicate, thanks to which they are not conspicuous and do not spoil the aesthetics of the building on which they are installed. The assembly itself is easy and quick.

The most important advantage LG MULTI MU3R19 and MU3R21 outdoor units is cooperation with three indoor units. They can be combined with various types of indoor air conditioners. Unlimited users can choose between indoor wall-mounted, cassette, ducted, ceiling-mounted or console air-conditioners and connect them to LG MULTI MU3R19 and MU3R21. Outdoor units LG MULTI MU2R15 and MU2R17 differ in cooling and heating capacity. for the device MULTI MU2R15 it is 5,3kW of cooling power and 6,3kW of heating power aw MU2R17 – 6,2kW of cooling power and 7,0kW of heating power.

What distinguishes the LG MULTI MU3R19 and MU3R21 outdoor units?

LG MULTI MU3R19 and MU3R21 outdoor units have been equipped with a number of modern technologies and solutions that improve the operation of the device. Can be found here Twin Rotary Inverter compressor driven by brushless direct current (BLDC) motors. The combination of an inverter compressor and a brushless motor translates into high work efficiency devices, also seasonal, and additionally on unit energy efficiency. In addition, in LG MULTI MU3R19 and MU3R21 applied Wide Louver Plus slatswhich slow down the heat exchanger defrosting process. The heat exchanger itself was covered GoldFin coating protecting it from corrosion. An additional hydrophilic coating accelerates the outflow of water from the heat exchanger and thus reduces its icing. All these innovations extend the unit's operating time between defrost cycles.

Users who wish to take advantage of developed by LG multi-split systemcan choose outdoor units MULTI MU4R25 and MU4R27. These are devices intended for installation outside the building and cooperating with four indoor units. they show up high efficiency i energy-saving even with maximum seasonal load. Indoor units, with different capacity and cooling capacity, connected to MULTI MU4R25 or MU4R27 external devices effectively cool and heat rooms.

Features of the MULTI MU4R25 and MU4R27 units

What makes it stand out MULTI MU4R25 and MU4R27 outdoor units, it is possible to work in night mode. In this mode, the device works a lot quieter and the noise level drops to a level that does not disturb the quiet at night. MULTI outdoor units MU4R25 and MU4R27 they are also equipped with a display located on the motherboard. It monitors and provides information about possible wiring errors. This gives the user an easy and transparent control of the correctness of the control wiring. These features are very valuable both for installation and for maintenance and checking connections.

A well-known and widely used solution in LG devices there is a connection Twin Rotary Inverter Compressor driven by brushless direct current (BLDC) motors. This connection gives users high performancework efficiency and energy saving. To increase energy efficiency also has an impact intelligent control of refrigerant pressure. IN units MULTI MU3R19 and MU3R21 the cooling and heating capacity is slightly different. for the device MULTI MU3R19 it is 7,0kW of cooling power and 8,4kW of heating power aw MU3R21 – 7,9kW of cooling power and 9,1kW of heating power.

Checked solutions

W MULTI outdoor units MU4R25 and MU4R27 a number of solutions and good practices tested in other models of a similar type have also been applied. These include, among others Wide Louver Plus slat technology, GoldFin coating on heat exchanger and a hydrophilic coating that accelerates the drainage of water from the heat exchanger. All these elements translate directly to extending the service life of the outdoor unit and extending the operating time between defrost cycles.
