Biological decay heat utilisation equipment - has heat pump combined with decay box

摘要

The equipment utilises the heat generated by biological decay of organic matter by a heat pump (16). The latter is combined with a decay box, which can contain a conveyor system turning over the material, and loading and discharging it. The box can be divided by a central sloping buffer wall (3) into two chambers (4,5), while the top can be covered by a heat exchange surface, or an absorber. All walls, including the buffer wall, can act as heat exchangers, and there can be a temperature restrictor to prevent excessive cooling of the biological material.
