The developments of pervasive sensors for Heating, Ventilation and Air
Conditioning (HVAC) process has been attracting increasing attention over the years.
Information from these sensors carries complex interrelationships between the
thermodynamic parameter of HVAC. Therefore, the extraction of key relationships
from these pervasive sensors that drive the heat exchange phenomena, including their
interactions with the environment and users are to be discovered.
Information fusion from multi-modal data source, ASHRAE RP-884 Adaptive
Model of Thermal Comfort and Performance with simulations using MATLAB® is
proposed to analyse the heat exchange phenomena. Feed forward neural networks
model, Extreme Learning Machines (ELM) is used to analysis the testing accuracy
based on the target values and its variables.
Correlations of variables with PMV and ASHRAE shows different outcome with
additional variables through ELM testing accuracy. This study shows how
correlations were established using ELM with given data variables and randomly
generated variables.
Six primary variables of predicted mean vote (PMV) index calculation by Fanger
were used from RP-884 data and randomly generated variables. Addition of available
data variables from RP-884 is used to discover the relationship of PMV and
ASHRAE thermal sensation scale. The target values used for the ELM technique are
PMV and ASHARAE thermal sensational scale. ELM results shown that the testing
accuracy does not necessary improve with additional variables |
