USE OF A REGENERATIVE AIR-TO-AIR ROTARY HEAT EXCHANGER FOR HEAT RECOVERY IN RESIDENTIAL VENTILATION SYSTEMS.

With the increasing cost of energy supply for residential houses, the economics of reclaiming waste heat from residential ventilation systems have become very significant. This paper discusses the use of a regenerative air-to-air rotary heat exchanger for heat recovery in residential ventilation systems. Some of the potential operating problems in low temperature environment, such as frosting, are also discussed.
