Abstract

This application relates to a modular cleanroom heat recovery fresh air unit, belonging to the technical field of fresh air treatment equipment. Its casing is divided into upper and lower layers of fresh air channels and exhaust channels, with a heat recovery module embedded in the middle. The heat recovery module includes a chamber and a transposition structure within the rear hood. A first heat recovery core and a second heat recovery core are mounted vertically at the front of the transposition structure. The transposition structure is driven by a dual-motor gear plate and rack and pinion transmission, causing the two cores to first retract laterally within the chamber, then transpose vertically, and finally push laterally to adhere to the sealing element. The internal partition and sealing strip form a unique isolation line. The sealing element is actively pressurized by a third motor-driven screw, forming a double seal with the core's elastic sealing element, ensuring dynamic absolute isolation between fresh and exhaust air and eliminating cross-contamination. Furthermore, the unit adopts a modular design, allowing individual replacement of the core units. It integrates pre-filters, high-efficiency filters, and auxiliary heat exchange coils, resulting in a compact structure and convenient maintenance.
