To overcome the disadvantages of the conventional heat recovery units used in air conditioners, the heat recovery unit proposed uses a continuous and circulating heat-recovery band as a heat-bearing medium; this can consist of a multi-layered copper or aluminium wire braiding or knitting. This heat-recovery band is permeated twice by both the warm outgoing air from an air conditioner and by the cold input air, and this results in a high degree of efficiency. The heat-recovery unit according to this invention is provided between the outgoing and input air sections with a sealing unit to prevent any direct flow between those two areas. |
