LG has become one of the first manufacturers in the UK marketplace to launch an air conditioning range operating on R32 refrigerant with the launch of its Single Splits and Multi Split Smart Inverter products.
The new LG range line up offers external units from 4.1kW up to 18.7kW and internal units, as well as the 4 way Ceiling Cassette, Ceiling Suspended units and its Ceiling Concealed Duct units.
The technologies developed by LG achieve world class low energy consumption levels, particularly in relation to the SEER value, with regard to ErP regulations, with 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.
The units utilise a Brushless Direct Current Motor which offers 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.
LG’s unique Smart Load Control technology allows the new units to save operational energy and automatically control the refrigerant temperature according to load. 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, which is highly corrosion resistant. 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 ten-year warranty. It features Oil Flow Optimisation, concentrated winding motor, a twin rotary rotor, suction optimisation and excellent surface coating with outstanding abrasion resistance properties on the vane and the crank shaft.
The external units come with an improved fan that features a Mogul trailing edge which reduces the vortex, a reverse hub and a narrow hub blade which reduces the friction and improves the flow rate. It has a thick leading edge to enhance tip rigidity and streamline the rotation, whilst a saw tooth trailing edge reduces the vortex intensity. So overall, the new axial fan helps to reduce noise levels and improve efficiency still further. The new units feature Night Silent Operation, by simply setting the dip switch on the PCB of the outdoor unit – reducing the sound levels to 46-48 dB.
You can control these latest LG air conditioning units via smart internet devices. A wide range of functions from simple on/off to mode selection, set temperature, to energy monitoring, filter management and even Smart diagnosis. The status of the air conditioner can also be monitored and problems diagnosed by connecting the unit to a Smart phone via a SIMS chip.
The new internal wall mounted LG units feature Auto Cleaning – cleaning the filter with regular airflow and removing harmful particles, preventing bacteria, mould and odours that can otherwise accumulate in an indoor unit. The larger Skew fan incorporated enables the cool air flow to reach all extremities of a room, keeping the space cool and comfortable.
The ceiling concealed duct units feature a high head drain pump that automatically drains water up to 700mm of drain head height. It’s the perfect solution for water drainage. The unit features dual thermistors – one in the indoor unit and another in the remote controller.
