Author(s) : ANDERSSON B., et al.

Type of article: Article

Summary

Describes a study of the re-entrainment of tracer gas and formaldehyde via six rotary air-to-air heat exchangers (all enthalpy exchangers) in the north of Sweden. Five were in office buildings and one was in a day-care centre. Formaldehyde in indoor air was used as a monitor pollutant. Describes the sampling process. The calculated re-entrainment of formaldehyde was 1-9%. Concludes the results show that rotary heat exchangers can be used in buildings where activities produce low levels of air pollutants, provided that the exchanger is properly installed and maintained.
