The HVACR industry in Australia is undergoing a period of significant change with a greater focus on energy efficient products and sustainability.

One technology that has stood the test of time is water source systems, according to Russ Prendergast, LG Australia's marketing manager for air conditioning and energy.

Referring to the Multi V Water IV, which is the most recent innovation from LG, he said this unit is specifically designed to respond to the current market trends and requirements.

“Although there have been new products from several HVAC providers in this space, the LG Multi V Water IV module provides a number of significant advancements,” Prendergast said.

“The new and improved modular condensing units measure just 755 x 997 x 500 in dimension, compared with the market competitors which are 12 to 77 per cent larger in a single module format.

“Plus, the weight is 15 to 42 per cent lighter which means that each stackable unit takes up significantly less space.”

The new Multi V Water IV has a wide range of unit capacities from 22.4kW – 56kW are available in a single condenser, including 33.6kW and 35.3kW models. With a single module condenser LG can design an indoor connection ratio of 50 – 200%. The rare option of being able to select the best size for each application all in a smaller and lighter foot print.

Prendergast said the Multi V Water IV efficiency is aided by its large stainless steel heat exchanger and all inverter compressor system.

He said the energy efficiency ratio is between at 5 and 6 depending on the model, plus our patented HiPOR (oil return system) and Active Oil management which detects the oil level in the compressor reducing wasted time in the oil recovery process.

“The new 4 series indoor units feature connection to the LG refrigerant leak detector for real time refrigerant leak detection that recognises leaks and informs the user immediately through an alarm and a visual warning on the control panel,” Prendergast said.

“With effective management, this feature prevents the risk of compressor burn out and increases the overall reliability of the system.”
