Validation et amélioration du test Delta-Q destiné à déceler les fuites.

Validating and improving the Delta-Q duct leakage test.

Auteurs : DICKERHOFF D., WALKER I., SHERMAN M.

Résumé

This study uses detailed laboratory measurements to validate the Delta-Q test procedure and calculations. The laboratory measurements used a purpose-built test chamber coupled to a duct system typical of forced-air systems in US homes. Special duct leaks with controlled and monitored airflow were designed and installed in the duct system. This test system enabled the authors to systematically vary the duct and envelope leakage and to accurately measure the duct leakage flows for comparison to Delta-Q test results. The laboratory testing has also led to enhancements to the Delta-Q calculations that increase the accuracy of the leakage measurement.
