How to have a highly efficient, reliable cooling, lower running costs

By David Indeje / July 11, 2019




All modern buildings face the challenge of keeping cool, whether it’s having to cope with the sun’s baking rays or the excess heat generated by the raft of equipment inside. For reasons of comfort and safety, the temperature must be kept within a certain range, both to ensure the occupant’s wellbeing and the proper functioning of electrical appliances, computers, and other devices. Of course, the solution is effective air conditioning. And for larger buildings and commercial sites, a centralized system utilizing the latest chillers is arguably the best choice.

For those thinking about switching their worn-out chillers to brand-new ones, or transitioning to chillers from a different type of solution, a knowledgeable, forward-thinking HVAC consultant can be an invaluable resource. With their experience and industry savvy, they can suggest the most efficient products on the market, helping clients to choose the option best suited to their needs. A good consultant knows that efficiency is a must – especially for commercial spaces – as are cost-savings and reliability. If a facility is occupied or operates around the clock, having all three is 100 percent essential.

Now, skeptics may ask if a chiller can really fulfill all three of these critical requirements. “Does such a well-rounded solution even exist?” they might say. The short answer is, “Yes.” Designed to save users money, time and space, the LG Air-cooled Inverter Scroll Chiller is an all-in-one solution for commercial buildings that boasts efficiency, reliability, and lower running costs.

Thanks to its Twin All Inverter scroll compressor, the LG Air-cooled Inverter Scroll Chiller has a wide operational range of 30-127 Hz, with improved energy efficiency in part- and full-load conditions. Where other chillers constantly turn on and off in order to maintain a constant speed and provide adequate climate control, LG’s solution simply adjusts output per load. This means that in partial load, it can cut power usage by an astonishing 80 percent and minimize hunting of water outlet temperature.

LG’s patented HiPOR™ technology further boosts the efficiency of the Twin All Inverter. In conventional compressors, oil returns through the same pipe that refrigerant flows, which inevitably leads to energy loss. HiPOR™ prevents this from occurring by returning the oil directly into the compressor. Because the flow of high-pressure refrigerant is not restricted by sharing space with the oil-return function, energy waste is largely eliminated.

Along with cutting-edge technologies, unparalleled reliability is built into the LG Air-cooled Inverter Scroll Chiller. An automatic emergency backup ensures the whole system remains operational should an individual unit encounter an interruption in service, or need to be repaired. The chiller is also equipped with an advanced black box that records even the smallest operational details, so users can quickly pinpoint the cause of an issue. And to alleviate any concerns about durability, clients can opt for the Ocean Black Fin heat exchanger, and Dual Protection Coating for core components, both of which offer additional protection against corrosion. An extra line of defense that’s particularly apt for buildings located in coastal areas, these features help extend product lifespan and reduce maintenance costs.

LG’s solution checks the efficiency and reliability boxes, but what about its scale? There are many things to consider when it comes to installation and the size of the solution is right up there with other important factors such as a building’s structure and layout, and regulations regarding noise and energy consumption. Big on performance, the LG Air-cooled Inverter Scroll Chiller has a relatively small footprint that translates to efficient space utilization. It’s also simpler to install thanks to a modular design, which conveniently allows for easy system expansion at a later date. And at 68 dB(A), the Air-cooled Inverter Scroll is approximately 8 dB(A) quieter than competing products, contributing to a more pleasant indoor and outdoor environment. Up to five of LG’s chillers can be managed via a single HMI Touch controller and AC Smart controller, and as many as ten through an Advanced Control Platform (ACP), saving building owners and facility managers time, money, and a lot of unnecessary stress. With centralized control, a variety of functions including cycle monitoring, schedule control, and demand control can be easily accessed from one place. The controller also has a range of 500 meters, enabling the user to monitor and change settings from the comfort of their office.

The LG Air-cooled Inverter Scroll Chiller represents a tailored solution that delivers on performance, efficiency and operational savings. Clearly demonstrating that a chiller can indeed “do it all,” the advanced, versatile system reiterates what many already know to be true of LG: the company doesn’t compromise when designing its world-class HVAC systems. If beating the heat without breaking the bank is something that holds appeal, then LG’s air-cooled scroll chiller with industry-leading inverter technology is surely a good place to start. Just ask any in-the-know consultant.
