空気調和機
Document Type and Number:
Japanese Patent JP7162493
Kind Code:
B2
Abstract:
To provide an air conditioner which makes dust entering into a ventilation passage less likely to affect the air conditioner to improve pressure detection accuracy.SOLUTION: A ventilation passage 9 is provided with an orifice 15 and a pressure sensor 16. The pressure sensor 16 includes an upstream pressure detection port 31 and a downstream pressure detection port 32. The upstream pressure detection port 32 is connected to an upstream pressure detection passage 28 extending from an upstream communication hole 27 at the upstream side of the orifice 15. The downstream pressure detection port 32 is connected to a downstream pressure detection passage 30 extending from a downstream communication hole 29 at the downstream side of the orifice 15. The upstream pressure detection passage 28 includes an inclined guide part 33 which extends from the upstream communication hole 27 in an opposite direction of airflow passing through the orifice 15 and inclines in a direction which is gradually spaced apart from the ventilation passage 9.SELECTED DRAWING: Figure 3
