Variable refrigerant flow (VRF) has about 24% of the global commercial air conditioning market, and over 35% market share in China, India, the European Union, and Eastern Europe. The VRF share of the U.S. market is still only about 3%, but multiple manufacturers sell these systems in the U.S. and sales are growing.
This 3-hour course describes how VRF systems operate, as well as why these systems have the potential to provide energy savings over the traditional systems used in U.S. commercial buildings today.
