Cowshed air conditioner or heating system - uses heat exchanger in dung aerating pit for refrigerator or underfloor heating

摘要

The air conditioning system for a cow shed or similar animal raising building uses the heat generated by the collected manure. This falls through the grid floor (3) into a chamber (6) below, to pass into a pit (7) alongside the shed. Air is pumped into the material (8) collected in the pit by an injector pipe (9) at the bottom, connected to atmosphere. This action causes heat to be generated, and heat is extracted by a heat exchanger (13) also inside the pit. This heat can be used in heaters (15) embedded in the floor, or alternatively in an absorption refrigerator unit (16) alongside the shed.
