Filed:

Aug 23, 1982

Appl. No.:

6/410448

Inventors:

Ben B. Herschel - Howell NJ

International Classification:

F26B 1104

US Classification:

34 86

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.

Abstract:

A face-and-bypass heating coil has features which allow the device to be mounted either horizontally or vertically without loss of mechanical or thermal efficiency. The invention includes a frame comprising a pair of side panels which support the working mechanism, and upper and lower panels. A plurality of fixed partitions are attached between the upper and lower panels. A plurality of movable dampers are mounted on shafts and supported by linear ball bearings such that the movable dampers may selectively mate with the fixed partitions. A crank linkage is used to drive the movable dampers into and away from the fixed partitions. The elastic U-shaped structure of the movable dampers resiliently mates with the fixed partitions so as to form a substantially leak-proof seal around the heating tubes.
