LG's range of single and multi split Smart inverter air conditioning products operating on R32 refrigerant is now available in the UK.
The new line-up offers external units from 4.1kW up to 18.7kW and internal units that include its Artcool Mirror, Deluxe, Standard and Standard Plus wall units, as well as the 4-way ceiling cassette, ceiling suspended units and ceiling concealed duct units.
The units achieve SEER values up to 8.50 for the 4.1kW, 5.3kW and 6.2kW outdoor units, equating to A+++ levels, and all the other units meet A++ standards. A brushless direct current motor is said to offer additional energy savings of up to 40% at lower speeds. LG’s Wide Louvre Plus Fin technology increases full load heating performance by 11% and 6% COP compared to conventional fin technology.
Smart Load Control allows the new units to save operational energy and automatically control the refrigerant temperature according to outside temperature. The mode lock function enables the setting for the system to be set to either heating only or cooling only by adjusting a dip switch which prevents mixed use of cooling and heating in the building. And the standby mode on the new units can minimise power consumption by up to 90%, by turning power off on the PCB except for the MICOM, which receives signals.
The new external units feature Ocean Black Fin coating on the heat exchanger, designed to perform well in corrosive environments such as contaminated or humid conditions. This ensures longer lifespan and lower operational costs for the units. As well as contributing to reliability in a system, the new LG units offer quicker response times to providing heating and cooling from the dual sensing system incorporated, utilising not just the traditional temperature sensor approach but a dual sensor approach using temperature sensors and pressure sensors reducing the time delay for implementing the heating or cooling commands significantly.
Pressure control takes less time to reach the desired temperatures – with up to 30% quicker response in cooling and 44% quicker response in heating, with a high level of accuracy and stability built in. The new LG units incorporate a new twin rotary inverter compressor that comes with a 10-year warranty. It features oil flow optimisation, concentrated winding motor, a twin rotary rotor, suction optimisation and surface coating with outstanding abrasion resistance properties on the vane and the crank shaft.
The external units also include an improved axial fan and the Night Silent Operation reduces sound levels to 46-48 dB.
The units can be controlled from a smartphone, with options including mode selection, energy monitoring, filter management and diagnosis. Engineers can use LG Monitoring View helping them to inspect and monitor air conditioning units with ease. For the wall mounted units you can monitor the status of the air conditioner and diagnose problems by connecting the unit to a smartphone via a SIMS chip. You can set the daily temperature and automatic on/off time for a week.
Internal wall mounted units are said to offer a range of benefits including the inclusion of a plasma ioniser to protect from odours and harmful substances. It sterilises and deodorises, reducing harmful microscopic particles, utilising over 3 million ions by infusing the air passing through the air conditioner. They feature auto cleaning of the filter and operate at 19dB.
The ceiling concealed duct units feature a drain pump that automatically drains water up to 700mm of drain head height. They also boast dual thermistors – one in the indoor unit and another in the remote controller. The noise level of low static ducts have been reduced significantly to just 27dB.
