DOMESTIC AIR CONDITIONING
The green choice for the wise
Andrew Hooper, UK and Ireland heating manager at LGE lifts the lid on LG’s Therma V R32 split systems.

f you consider yourself ‘in-the-know’, you’ll most likely be thinking of purchasing an Air to Water Heat Pump (AWHP) system to stay warm this winter. However, it pays to be aware that not all AWHPs are created equal. The best options deliver performance and
convenient control and, importantly, are able to comply with tough, new environmental and energy regulations. For consumers in Europe, finding a solution that meets each criterion can be challenging. This is because the European Union has some of the most forward-looking eco-legislation on the planet. Its F-Gas laws, which were enacted in
January of 2015, were introduced in an effort to help the environment by steering manufacturers and consumers toward doing the right thing: going green. With the F-Gas laws in place, the use of R32 refrigerant will no longer be optional; any AWHP without it won’t make the grade. R32 has a much lower Global Warming Potential (GWP) than the widely employed R410A, which will soon be phased out in Europe. A compressor that’s light on energy consumption is also something to look for when choosing an AWHP. The compressor accounts for approximately 90% of a system’s electricity consumption, so it had better be efficient if its performance is to meet with current standards. Whether they’re building owners, property developers or home owners, prospective buyers should mark those two extremely important points down: an AWHP should have 1) R32

refrigerant, and 2) an efficient compressor if it is to satisfy their needs as users and measure up to the EU’s eco-conscious energy standards. A product that checks both of those boxes, LG’s Therma V R32 Split, has been designed to meet the most stringent regulatory constraints while benefiting users and installers with impressive efficiency and performance. It also helps to protect the environment through the use of sustainable technologies and reduced energy consumption. Using R32 refrigerant, the LG Therma V R32 Split achieves a Seasonal Coefficient of Performance (SCOP) of 4.65 in heating operation (dependent on a leaving water temperature of 35°C) and comes with an Energy-related Product (ErP) rating of A+++. The environmentally-responsible choice, R32 has a Global Warming Potential (GWP) of 675- 70% lower than that of R410A – and an Ozone Depletion Potential (ODP) of zero. Courtesy of R32, the Therma V R32 Split is also rewarding users with a lower monthly bill. Reliable heating during the coldest part of the year is another outstanding benefit supplied by LG’s latest model. The Therma V R32 Split can perform at an ambient temperature as low as -25°C. As mentioned earlier, a solution’s compressor is just as critical to its success as using the right refrigerant. For its latest AWHP, LG designed the new R1 compressor – the world’s first ‘shaft-through’ hybrid scroll- shaped compressor.
Taking the best elements of scroll- and rotary-type compressors, the R1 offers unrivalled performance and efficiency and allows for a marked improvement in operational range. Whereas its predecessor had a range of 15-100Hz, the new Therma V boasts a much expanded 10-135Hz range of operation with improved part-load efficiency.
How does this benefit the user? In short, it
means they get to enjoy their desired indoor temperature faster, or, put another way, more comfort in less time. A real game-changer, the R1 compressor also boosts the stability of the Therma V R32 Split and reduces energy consumption by eliminating the tilting motion common to conventional compressors. To help consumers make the green choice,
an AWHP must also be user-friendly. After all, the more convenient something is the more likely people are to use it. With the included RS3 remote controller, it’s quick and easy to check the LG Therma V R32 Split’s operating status and schedule and adjust energy consumption to reduce waste and running costs.
Thanks to a Wi-Fi module and LG’s smartphone app, SmartThinQ, users can monitor and remotely control compatible LG products, and access the vast majority of functions available on the Therma V R32 Split’s control panel. Via the app, it’s simple to set the perfect temperature from any location and return to a blissfully warm indoor environment. The HVAC industry has made strides towards becoming greener in recent years, offering more environmentally-friendly choices. Standing out from the crowd, LG’s latest Therma V R32 Split is a solution that wise consumers would do well to consider. Performance that’s reliable and efficient, and a compressor-refrigerant combo that reduces energy consumption and harmful emissions – it’s all there.
The Therma V R32 Split is proof that
consumers no longer need to choose between ‘going green’ and solid, reliable heating. Through continuous research and development, and a commitment to doing the right thing, LG has paved the way for a new generation of greener AWHP systems.
