Abstract(s) :

(Anglais) This study characterizes the amount (volume) and the temperature of the condensates obtained in an Earth-to-Air Heat Exchanger in Belgium (EAHE) to define if this particular biotope is propitious to the development of pathogenic microorganisms. Different numerical models of an EAHE have been developed and the results validated with experimental measurements. The total condensate produced in the model of EAHE studied was 25.22 kg in 2015 and 56.59 kg in 2016. Most of the condensation appears during June, July and August. The air temperatures at the outlet of the EAHE are quite close to the temperature of the condensates produced. These temperatures are between 3°C and 23°C, it’s very conducive to the development of psychrophilic microorganisms.
