33 dry compartment air healthful compartment air humidity:  = 30…60 % dry eyes dry nasal mucosa dry mouth by ventilation systems compartment air often too dry atmospheric air < 0 °C  room = 20…25 % r.h.

34 Humidity recovery With heat also humidity will be recovered – this increase the comfort and eliminate dry compartment air in winter. ~60 % humidity recovery results:  compartment air humidity increase 20 % r.h.  32 % r.h.  no anti-freeze protection until atmospheric air = -10 °C
