| Abstract | A study on energy uses in the Faculty of Tropical Medicine
(TropMed ) , a teaching and research centre and 160-bed hospital
was conducted. Energy audit for the electrical systems was
carried out in main buildings of the Faculty. Monthly and daily
electricity consumption profiles for each building are shown.
Breakdowns of electrical energy usage in various energy systems
are presented. The three main energy consuming systems are the
air-conditioning, the power and electrical equipment, a nd the
lighting systems . The percentages of electrical energy
contributed by these systems are 59%, 27% and 14% respectively.
The monthly electrical energy usage and cost indices for
each building are presented to compare the effectiveness of the
energy usage . For the Academic Building, the TropMed energy2 index
is about 11.15 kWh/m while that of AIT is only 3.09 kWh/m . The
index of the TropMed hospital laboratories and wards is compared
with Bumrungrad Hospital's index. The indices of both are about 5
and 70 kWh/in-patient day respectively. For more accurate
comparison, the number of out-patients in the hospital are also
taken into account. The index estimated based on an equivalent
in-patient day of the TropMed hospital is about 3.12.
The opportunities for electrical energy conservation in
various systems are identified and analysed. For the lighting
system, the electrical energy saving can be achieved by replacing
incandescent lamps by fluorescent tubes or SL lamps, and by
substitution of lower wattage of fluorescent tubes. The possible
saving is approximately 55,200 - 66,600 ·Baht/year and the payback
period is within 1 or 2 years depending on the conservation
measures taken . For the power and electrical equipment system,
conservation measure by power factor improvement gives the saving
of at least 71,200 Baht/year with the payback period of 19
months .
The performances of the air-conditioning systems in the main
buildings are also analysed. The window-type air condi ti.oners
have lower coefficients of performance (COP ) , ranged from 0.5 to
2 . 2, when compare d to the central air-conditioning system with a
COP of 3.0, used in a private hospital. The energy conservation
of air-conditioning sys tern can be achieved through a suggested
maintenance program. |
