General PURPOSE OF THE AIR INLET French Standard NF P 50-411 (DTU 68.2) of May 1993, concer-ning CMEV installations. Օ French Standard NF XP 50-410 (DTU 68.1) of July 1995 concer-ning the design and dimensioning rules of CMEV installations. NFE 51-732, test specification concerning the characteristics necessary to verify the quality of the external wall air inlets. Acoustic requirements Օ French Decrees of 30.06.1999 (which replace and rescind the NRA, Decree of 28.10.1994) concerning the acoustic characteristics of residential housing and their methods of application. ͕ French Decree of...

■ Dimensioning_ Airflows The air inlets, plus the permeability of the building's envelop should make it possible to obtain the dwelling's total exhaust airflow, whether the CMEV system is a constant flow system (self-balanced CMEV) or with modulated airflows (humidity- controlled CMEV). Self-balanced CMEV Self-balanced air inlets : EMMA, EA, EAI, ELLIA. The requirements set by the XP P 50-410 (DTU 68.1) standard impose a maximum negative pressure of 20 Pa in the dwelling, which defines a typical dimensioning according to permeability values set in this standard. Gas heating Number of main...

General INSTALLATION Diffrent types of assembly Depending on the site dtails (type of ventilation, type of work) and after airflow and acoustic dimensioning of the air inlet, dif驭ferent types of installation are possible. The CMEV air inlet can be installed either by: - penetrating through window frames (PVC, wood or aluminium window frames, roof window ...), - penetration through the top of windows, - penetration through masonry, - penetration through a roller blind case. Installation in a roller blind casing Dimensions of standard slots The slots necessary for the installation of the air...
