Farm animal stall air conditioning system - has heat exchanger between stale and fresh air conduits

摘要

The farm animal stall air-conditioning system has one or more fresh air ventilation conduits, supplied with fresh air by a blower. It incorporates a heat exchanger (5) transferring sensible heat between two passages, one of which is connected to the discharge passage (3) mounted inside the building, and the other to a passage (6) lead-to the intake of the blower (4). The heat exchanger can be of the rotary type. The ventilation conduits can be mounted near the building walls, discharging air via openings against the latter. A second blower can be provided, to exhaust the stale air.
