Large-scale composting assembly has an air cooling system that surrenders heat to ambient locality by convection and radiation

摘要

A tunnel or container composting assembly has a tubular section (10-12) with a first air cooling system (7) that surrenders heat to the ambient environment by convection and radiation. The cooling system (79 also forms part of a ventilation duct (24). The ventilation duct incorporates a second cooling unit (8) that uses a liquid coolant register and operates in series with the first (7). The second cooling unit operates in step with the first.
