Abstract
This study investigates the comfort performance of a test room equipped with the southfacing
photovoltaic wall (PV-W) and north-facing thermo-electric air duct (TE-AD) system
for the tropical climate. Both subjective and objective measurements were used to
analyze the TE-AD system cooling performance when operated at variable input current
supply (2e7 A) from a PV system. Indoor radiant and air temperatures, relative humidity,
and air velocity were measured based on ISO 7730 for objective measurement. For subjective
measurement, forty respondents were required to fill up the questionnaire that
developed based on UNI EN ISO 10551 and UNI EN ISO 7730 guidelines in order to access
their thermal comfort opinion. The results show that the thermal response of respondents
associated with indoor situation of the test room have changed from (รพ1) slightly warm to
cool ( 2) when the input current supply rises from 2 A to 6 A. The overall predicted mean
vote, predicted percentage dissatisfied indices, and acceptability vote shows that more
than 90% of the respondents were thermally satisfied. Integration of the PV-W system with
the TE-AD system increases the thermal comfort and reduces the thermal load of the test
room with other benefits includes less fuel and energy consumption, high reliability, and
less maintenance operation.
