Cleaning initiation criteria for heating, ventilation and air-conditioning (HVAC) systems in non-industrial buildings.

Author(s) : LAVOIE J., BAHLOUL A., CLOUTIER Y., et al.

Summary

The objectives of this study are to reproduce in the laboratory different levels of cleanliness in non-porous ducts of HVAC systems, to compare a new method for sampling surface dust in ducts with those methods cited in the literature, to compare the numerical evaluation method to the visual method, and to propose objective cleaning initiation criteria. For each of the simulated cleanliness conditions, a committee of specialists did a visual assessment based on a scale of 3, where level 1 meant normal, 2 meant above normal, and 3 meant serious. According to these assessments, the established initiation criteria correspond to 0.2 g/m2 for the NADCA method, 0.3 g/m2 for the ASPEC method, and 0,6 g/m2 for the new method. These criteria are significantly different. Any of the surface sampling methods can be used, insofar as the corresponding initiation criterion is used.
