Description

Technical Field

[0001] This utility model belongs to the field of subway air conditioning technology, and more specifically, it relates to a multi-functional air outlet for subway air conditioning. Background Technology

[0002] Subway ventilation and air conditioning are mostly installed on the top of the subway car. A high-power central air conditioning unit is installed inside the top shell of the subway car. Air outlets are set horizontally on the top of the subway car, and support frames are installed on the air outlets. Wind deflectors are evenly arranged inside the support frames. The wind deflectors are equipped with a linkage rotation structure on both sides, so one wind deflector can be held and rotated to rotate the other wind deflectors until the desired wind force and direction are achieved.

[0003] The existing air vents are fixed to the top of the carriage. Considering that direct cold air in summer would affect passenger comfort, most of them blow air horizontally. As a result, the hot air from the air conditioner accumulates at the top of the carriage in winter. With each station, the temperature inside the carriage becomes uneven, reducing the comfort of the journey.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a multi-functional air outlet for subway air conditioning, in order to achieve a more practical value. Utility Model Content
