Brussels, 07 February 2023. The Eurovent Product Group ‘Energy Recovery Components’ has published a new Recommendation 17/13 on the recommended standard for interoperability between Energy Recovery Components (ERC) DLL’s and Air Handling Units (AHU) selection software.

The Eurovent 17/13 provides a recommend future standard to implement the provisions of EN 308:2022 and expected new Ecodesign requirements in AHU’s selection calculations with respect to internal leakage and moisture recovery. It specifies the principles of data exchange at the interface between the AHU and ERC software to account for the impact of internal leakage on AHU performance. The recommendation also comments on the implementation of ERC DLL outputs in AHU calculations.

Thomas Richter, Head of Product Management at Hoval and Chairman of PG-ERC states: “The Recommendation provides fundamental standards and as it comments on the implementation of ERC DLL outputs in AHU calculations, this reduces and helps avoid mistakes and misunderstandings in calculation of ERC-products in AHU-software. We are confident that this Recommendation will be helpful to the industry experts.”

This document was prepared in a joint effort by participants of the Eurovent Product Group ‘Energy Recovery Components’ (PG-ERC) and Product Group ‘Air Handling Units’ (PG-AHU), which represent a vast majority of all manufacturers of these products active on the EMEA market. The document can be downloaded free of charge in the Eurovent Document Library.
