Commercial Air Conditioning
2019 lineup of commercial HVAC solutions
LG ELECTRONICS HAS ushered in the year with its 2019 lineup of commercial and light commercial HVAC solutions – including indus- try-leading variable refrigerant flow (VRF) tech- nology, customizable and flexible control sys- tems, powerful new heating capabilities and a variety of design tools.
LG's latest vertical air handling units (VAHUs) for ducted residential and light commercial ap- plications provides superior design flexibility with four-way installation capabilities (vertical- ly, horizontally from the left or right, or inverted with a down flow conversion kit).
The new VAHUs now features a constant CFM motor which maintains a constant air flow for better efficiency and comfort.
LG's state-of-the-art air-source VRF systems, the Multi V 5 now boasts an expanded operating range to work in ambient conditions down to -22°F with the addition of LGRED heat technol- ogy making it the ideal year-round VRF solution.
The LG Multi V 5 is available from 6- to 42- tons, with a choice of three-phase 208V, 230V or 460V electrical power as heat recovery/heat pump outdoor units; the 20-ton unit represent-
ing the largest tonnage in the smallest, single frame footprint on the market today.
It is a smaller and lighter solution but perfor- mance is increased. The Multi V 5 20-ton not only reduces footprint requirements, but also helps to reduce installation costs.
The Multi V 5 has exclusive features such as Advanced Smart Load Control that proactive- ly addresses the impact of pending weather changes ensuring optimal comfort for all of the building occupants. The Multi V 5 also features LG Intelligent Heating technology that defrosts as needed rather than respond- ing once frost has reached a preset point.
It also features a biomimetic fan design mak- ing it operate more efficiently and increase air- flow while reducing the perceived noise level by approximately 20 per cent.
LG is also set to release its new high static duct- ed indoor unit. With a cleaner chassis design, the LG high static ducted units have a reduced height and overall width with the control box enabling for maximized design space. It is lighter and features bottom access to the control board for improved installation, commissioning and maintenance.

HLR technology is changing the game
CLIMATECONTROLNEWS.COM.AU
HVAC LOAD REDUCTION technology (HLR) from enVerid Systems has been labelled a game- changer for the entire industry by the American Society of Heating, Refrigerating and Air Condi- tioning Engineers (ASHRAE).
Each year at the AHR Expo one product is se- lected by a panel of ASHRAE judges as the most innovative and this year it was the enVerid HLR 1000E module.
Legacy commercial HVAC designs rely on massive volumes of outside airflow to maintain indoor air quality, resulting in oversized equip- ment and often a 30-50% waste in HVAC energy consumption.
To eliminate this waste, HLR technology cleans a building’s indoor air at a nanoscopic molecular level, enabling the building to use far less outside air ventilation while improving indoor air quality.
Buildings can then invest in smaller, less expen- sive HVAC systems and realize immediate capital cost savings while enjoying 20-30% ongoing an- nual energy savings for the life of the building.
Dr. Udi Meirav, founder and president of enVe- rid Systems, said this endorsement is recognition of the transformative potential of HLR technol- ogy for the entire industry.
