Primery energy consumption with varios regenerative techniques
The alternative 4 has the loweat primery energy consumption of all alternatives, i. e. heat recovery secures the highest energy saving the highest minimization of CO2
the highest effect of reducing fossil fuels

dry compartment air
healthful compartment air humidity: = 30…60 %
dry eyes
dry nasal mucosa
dry mouth
by ventilation systems compartment air often too dryatmospheric air < 0 °Croom = 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 increase20 % r.h. 32 % r.h.
no anti-freeze protection until atmospheric air = -10 °C
