ABSTRACT:
A self-contained heat recovery system for residential and commercial laundry dryers combines the principles of regenerative heat recovery with utilization of the dryer's existing drive apparatus to accomplish operation of the heat recovery system. The invention includes a rotary regenerative heat exchanger designed to permit planar adjustment of its surface; peripheral and airstream isolation seals to prevent loss of heat exchanger thermal effectiveness; apparatus for transmitting rotational forces from the laundry dryer tumbler to the rotary heat exchanger; cabinetry to function as a means of attaching the heat recovery system to the laundry dryer, as well as to provide airflow plenum chambers adjacent to the rotary heat exchanger to utilize existing airflow capabilities of the laundry dryer; cabinetry to further serve as structural support for rotary heat exchanger and its associated power transmission components.
