Applying power electronics to residential HVAC-the issues

Several of the market and application issues bearing on the economics of residential variable speed air conditioners and heat pumps are outlined. Technical details of capacity modulated systems are avoided, along with design issues involving power semiconductors, motor torque and speed control strategies, and integration in silicon for these applications. The author intends to provoke the development of creative improvements in the economics and application of variable speed electronics technology. He identifies the more important issues to aid the development of marketing strategies that will exploit the potential of air conditioning products containing power electronics, enabling them to penetrate the heating, ventilation, and air conditioning (HVAC) market and compete successfully against conventional systems
