VRF is LG's Most Advanced, for Many Commercial Applications
LG Electronics USA has introduced its new Multi V III Variable Refrigerant Flow (VRF) commercial air conditioning system for large-scale facilities, such as commercial office buildings, hotels, hospitals and schools.

The third-generation in LG's popular Multi V series uses innovative VRF technology that enables improved energy efficiency by allowing occupants to choose whether to air condition or heat only the zones in use. Multi V III will be LG’s flagship commercial HVAC system as it foresees continued growth in demand for energy-saving HVAC technology.

Sources say the LG Multi V III delivers six key benefits for building owners:

  • LG inverter scroll: a new high side shell innovation offers a more compact size for the same capacity output with greater reliability in cold climates.
  • Rapid start cooling: the fast response cooling or heating feature reaches room set point temperatures 40% faster than previous LG systems.
  • AHRI 1230 certification: sources report the Multi V III is one of the first performance-certified VRF systems. This insures building owners receive verified ratings which comply with all national energy codes.
  • Compact footprint: Multi V III supports more indoor zones and takes up less outdoor space. When space or access is at a premium, this equates to significant cost advantages for the owner on large projects.
  • Longer piping distances: owners can reach extra zones that are further away from the Multi V III unit. This eliminates the need to invest in extra systems and saves on installation.
  • Enhanced energy efficiency: the high side shell compressor, enhanced coil optimization, and a double spiral sub cooler result in verified efficiency improvements for new national energy codes.

Multi V III will be available in the U.S. beginning in Q4 2011.

Patent Pending Product To Make The Conversion From R-22 To R-410A Fast Safe and Efficient
The Oil Terminator removes mineral oils and solid contaminants and acids from existing copper tubing. According to company sources, it has a flushing system to make the conversion from R-22 to R-410-A fast , safe and efficient.

The Oil Terminator adapters can be attached and removed easily leaving the copper tubing undamaged. It can adapt to any size copper tubing from an 11/8-in. to 1/8-in. This new tool will allow technicians to flush both the high side and low side copper tubing, hands free. Once the technician has attached the adapters to the copper tubing lines he can go outside and remotely activate the flushing cycle. The Oil Terminator can be timed to pulsate the chemicals and nitrogen throughout the copper tubing lines. This pulsating timed feature makes sure all the mineral oil and contaminants have been completely removed. The range for remote activation of the oil terminator can be up to 80-ft. away. This remote activation will allow the service technician the ability to go outside and watch the flushing cycle from start to finish.
