Designs on smart cooling

LG has a brace of products breathing new life into the technology of splits, while retaining an element of style, as RAC reports

LG’s well-known Artcool range of indoor split and multi split units, available in a variety of 2.5 kW, 3.5 kW and 5 kW versions, offers an alternative to conventional white wall mounts, combining aesthetics and energy efficiencies for the domestic and light commercial markets.

The top of the range Artcool Gallery wall mounted unit is designed to resemble a framed picture and comes with a changeable photo for the front panel. LG also offers a selection of conventional standard white wall mounted units and also the Artcool Mirror unit, with a striking mirror finish (see below). 

The LG Artcool Gallery units are energy efficient, rated A/A, while the Artcool Mirror offers an A++ rating, and both use DC inverter drives, inverter driven fan motors and sophisticated controls. The DC inverter automatically adjusts the unit’s power to maintain room temperature rather than repeatedly starting and stopping the compressor.

Artcool units also offer night silent operation, LG says, along with its “neo-plasma” air purifying system, and other features such as auto cleaning and the manufacturer’s Gold Fin anti-corrosion technology for added longevity.

Artcool’s three-way blow configuration gives draught free airflow and when placed over a bed or desk it is possible to block the airflow to the bottom louvre, thereby avoiding drafts from the unit.

For quick room cooling such as in hotels, the JetCool feature is claimed to be able to cool a room to 18 deg C in just 30 minutes, while dehumidification mode accurately senses the room’s temperature and controls humidity without overcooling.

The Gallery units are designed with infra-red control and pipe access through the back so there are no untidy ancillaries to spoil the look of the installation, LG says. However, it notes that it’s not all about looks - the Artcool Gallery units promise a Seasonal Energy Efficiency Rating (SEER) of 5.3 and Seasonal COP of 3.5.

The Artcool Mirror units, meanwhile, offer a SEER of up to 6.2 and SCOP of up to 4.0.

At the same time, the high COP range of commercial splits or “H-Inverter” offers high efficiency for commercial applications via a wide range of cassette, ducted or ceiling suspended units. These split-type air conditioning units feature powerful air throw, allergy reduction filters and responsive step controls.

LG’s H-Inverter range is available in sizes from 3.5 kW to 14 kW, with 3-phase power supply options over 10 kW. System SEER’s can be up to 6.11, the manufacturer notes, with an energy rating of A++.

The system also offers significant design flexibility for a split type unit, the manufacturer adds, with piping lengths of up to 75 m, and a maximum height level difference of 30 m.

The H-Inverter claims significantly higher energy efficiencies than constant-speed non-inverter units, up to 60 per cent energy savings.

There are also a number of end-user benefits from using the range, LG says, such as the Plasmaster 4S (where the 4S stands for Skin Care, Silence, Safety and Savings), which encompasses a triple deodorising filter; a plasma filter; auto and a noise level of just 18 dB.

LG says its plasma Air Purifying System was initially developed to not only reduce microscopic contaminants and dust but to also remove house mites and other allergens that cause asthma symptoms. It uses an enzyme to destroy house mites, while dust particles are burned and eliminated by an electric field.

In addition, new Skew Fan technology ensures minimal noise from the unit, while by pressing the Quiet Mode button the fan speed automatically changes to “low” for lowest noise operation.
