AI Technical Summary

Technical Problem

Existing mechanical ventilation systems face challenges in accurately determining airflow rates through air ducts due to the inaccuracy and high cost of differential pressure sensors, which require significant space and are difficult to integrate.

Method used

An air handling kit using two absolute pressure sensors, one on the air fitting and one on the air box, to determine airflow rates, offering a more precise, cost-effective, and space-efficient solution.

Benefits of technology

The system provides accurate airflow rate measurements with reduced integration complexity and cost, enhancing the precision and efficiency of airflow modulation.

Abstract

The invention relates to an air handling kit comprising: - an air handling unit (28) further comprising a plurality of connection ports (30) for connecting a plurality of air fittings (20) to an interior space of the air handling unit (28), - at least one air fitting (20), characterized in that the air handling kit further comprises: - at least one first absolute pressure sensor (60) carried by said at least one air fitting, - a second absolute pressure sensor (62) carried by the air handling unit (28) for determining a reference pressure of the air present outside the air handling unit, - a controller configured to determine a flow rate value of an airflow circulating through said at least one air fitting (20) as a function of the air pressure of said at least one first sensor and the reference pressure of said second pressure sensor.
