South Korea's LG Electronics, the largest air conditioner manufacturer in the world, said Tuesday it is targeting a twofold jump in its commercial air conditioner market share in North America.

In a related move, LG participated in the 2010 AHR Expo Monday in Orlando, Florida to unveil 25 new commercial air conditioner models and Energy Star-labeled residential models, the company said.

LG also said it has been expanding its infrastructure for commercial air conditioners (CAC) in the North American market, as it has opened its second LG CAC Training Academy last December with plans to build two more by the end of the year.

The AHR Expo is the world's largest heating, ventilation, air conditioning, and refrigerating exposition, where more than 1,800 exhibiting companies from over 120 companies showcase their new product lines.

The Energy-Star label, awarded by the U.S. Department of Energy and the Environmental Protection Agency, is only given to products that prove it is significantly more energy-efficient than regular products.
