Özet:

 


Varying cooling load requirements in HVAC system become a major concern
to many consumers because of the additional cost of electricity. The cooling
load variation of HVAC system usually occurs when the domestic house door is
frequently kept open for prolonged durations, which is particularly important
in hot seasons. The present study, addresses a comparison of energy consumption
due to the thermal disturbance during domestic house door  keep opened for various duration when the
Variable Frequency Driver (VFD) and ON/OFF controllers are installed in HVAC
system. The experiments are carried out in two identical houses during six warm
days in a hot season where the outdoor temperatures have similar patterns
throughout the days. The energy response of HVAC system is analysed
incorporating the thermal and the electricity consumption data because of the
change of the indoor temperature during opening of the house main door. The
cost analysis is carried out and it is extended to include several repeats of
door opening durations. It is the first time demonstrated that the energy
consumption for HVAC system increases dramatically when the house main door is
kept opened for several times in a day. The energy consumption and additional
cost increase significantly for the case when the period of the main door
opening is extended. In this case, VFD A/C controller unit achieves more energy
savings than that of ON/OFF A/C controller unit.
