Resumen:
The objetive this work is to use the eletrodialytic hydrogen as fuel to
heating environment. An bipolar electrodiaser of 2kWh was used as source of
energy to study the performance of a convective heat exchanger adapted to use
hydrogen.
The convective heat exchanger was tested to heating a room of 15,45 m3
and the profile of the temperature curves during two different periods, day and
night, were studied. After that the heat exchanger was connected a chimney to
use combustion gases to exchange the heat with internal environment.
To analyse the performance of the two systems were studied the
following parameters; variation the internal and external temperature room,
hydrogen consumption, electrical energy consumption, the ratio between
acumulated and absorbed energy during the heating process.
From the results to both systems was observed that the convective heat
exchanger with chimney presented better performance. The energy efficiency
during night period of was 4,8% greater than that obtained from the
convective heat exchanger which was of 17,5% during day period. The results
obtained in this researche showed that electrodialytic hydrogen can be used as
fuel to heat exchanger to heat environment and also to substitute the fuels
from the petroleum.
