Abstract

Comparing with single photovoltaic (PV) or thermal Trombe wall systems, combined
PV/T offers better performance and efficiency. In this research, room air comfort for
human activity examined. An 0.5x0.5x0.5m room models built with different air gap
value, 3; 4.5; and 6 cm. The data acquired within 10 minutes interval, between 8am until
7pm. Data acquisition equipment provides an easier data collecting. In this research, in
order to get temperature and relative humidity (RH) data, series of LM35 and DHT11 are
used. Acquired data shows that combination of PV/T with air gap variations makes an air
temperature and RH differencies within the models. Higher room air temperature occurs
in smaller air gap variations (3 and 4.5 cm). Plotting air temperature and RH data to
human comfort chart, resulted that almost all conditions are not in human comfort zone,
due to higher air temperature. In the other hand, a PV/T system can generate electricity
to power the other system.
