We are evaluating the feasibility of implementing, within a residential building, a window‑integrated mechanical ventilation unit featuring a variable outdoor airflow capacity ranging from 15 m³/h to 80 m³/h.
The device incorporates an F7 supply-air filtration stage, a dual cross‑flow heat exchanger, and an enthalpic recovery module for sensible and latent heat exchange.
The system architecture allows for either localized supervisory control on a per‑window basis or full integration into the Building Management System (BMS).
We seek to determine whether such a system is admissible within the referenced protocol and, critically, whether it complies with the requirements of ASHRAE Standard 62.1. and 62.2 Notably, due to spatial constraints, installation of an airflow transducer on the supply-air path is not feasible; however, fault detection and system diagnostics are managed through the supervisory platform.
Additionally, the separation between supply and exhaust openings is approximately 50 cm.
