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
