Eurovent releases first Industry Recommendation on moisture recovery in HVAC systems

Eurovent has released the first edition of its Industry Recommendation 17/14, addressing moisture recovery in ventilation and air-conditioning systems. Published on 5 June 2025, the document provides guidance for the application of combined sensible and latent heat recovery technologies in HVAC systems.

Developed by Eurovent’s Product Group ‘Energy Recovery Components’ (PG-ERC), the recommendation targets investors and HVAC professionals involved in system design. It outlines key technologies—enthalpy plate exchangers, rotary heat exchangers, and alternate storage systems—detailing their efficiency, operation, and performance in varying conditions.

The document explains how moisture recovery can reduce energy consumption in both cooling and humidification processes. It includes comparisons of system performance with and without moisture recovery across different European climates, and outlines potential financial savings based on reduced power demands and lifecycle costs.

“Applying proper heat and moisture recovery exchangers significantly contributes to improving indoor environmental quality and reducing energy consumption,” states the introduction.

Eurovent 17/14 also covers aspects such as hygiene, maintenance, and control strategies for moisture recovery systems. The recommendation does not confer any certification; performance certification remains under the scope of Eurovent Certification.
