State-of-the-Art in Residential and Small Commercial Air Handler Performance

Description: Although furnaces, air conditioners, and heat pumps have become significantly more efficient over the last couple of decades, residential air handlers have typical efficiencies of only 10% to 15% due to poor electric motor and aerodynamic performance. These low efficiencies indicate that there is significant room for improvement of air handler fans. The other 85-90% of the electricity used by air handlers is manifested as heat. This extra heat reduces air conditioning cooling and dehumidificati… more
