[Health problems in air-conditioned treatment rooms in a pediatric intensive care unit].

Personnel of a pediatric intensive care unit claimed health problems due to air draughts. Mucous membrane symptoms such as burning eyes, an increased number of colds as well as headaches and stiff necks were the most frequent complaints. According to our indoor climate analysis high turbulence intensities were the main cause for thermal discomfort (Tumax = 88%, Tumin = 50%, median = 58% at measuring position Nr. 7). The percentage of people dissatisfied due to draught (PD value) were for example PDmax = 31%, PDmin = 6.7%, median = 16% at measuring position Nr. 7. In addition the humidification device of the HVAC system was not run continuously resulting in relative humidities below existing standards (51% r.h. in summer and 28% r.h. during the heating period).

Air-conditioning characteristics of the human nose.

Nasal inspiration is important for maintaining the internal milieu of the lung, since ambient air is conditioned to nearly alveolar conditions (body temperature and fully saturated with water vapour) upon reaching the nasopharynx. This literature review of the existing in vivo, in vitro and computational studies on transport phenomena that take place within the human nasal cavity summarizes the current knowledge on air-conditioning characteristics of the human nose.

[Effectiveness of the maintenance operations on the air conditioning systems of a university building in relation to the microbiological quality of the air indoor].

The microbiological quality of the air indoor is influenced from various factors and one of the most important is represented from the maintenance of the conditioning systems. In this study it has been estimated the effectiveness of an intervention of cleaning and maintenance on the systems of conditioning of an university building executing sampling before and after such intervention. The two results were confronted and it is observed as the maintenance of the air conditioners has influenced on the quality of the air indoor.
