Description

Technical Field

[0001] The utility model relates to the technical field of clean workshops, in particular to a dry coil bypass air flow resistance balancing structure. Background Art

[0002] High-purification cleanrooms generally use FFU + dry coil form. When the room heat load is small, only part of the circulating air needs to pass through the dry coil to control the room temperature.
