Energy Conservation Projects
Central Hospital has a number of
highly inductive equipments like
centralized air-conditioning plant,
boilers, incinerators, window &
splitair-conditioners, submersible
pumps etc. Based on
373
recommendations of internal energy audit, 250 KVAR Automatic Power Factor
Corrective Panel was installed for catering low PF feeders. This has resulted in
substantial saving of 2.47 Lakh units in the last financial year.
1. Majority of luminaries in Central Hospital were 40 W Fluorescent Lamps. A
drive was launched to replace such energy-inefficient fittings by 1X28 T5 or
2X28 T5 fittings. Total 245 such fittings were provided at various locations of
hospital in place of old single or double T-12/T8 fittings during 2013-14,
resulting net saving of 0.73 Lakh units of electricity.
2. Central hospital was equipped with old fashioned rheostatic fan-regulators
which were contributing to lot of energy wastage. Based on internal audit
report, all such regulators have been weeded out and replaced by electronic
type fan-regulators. An estimated amount of 0.10 Lakh units have been
saved due to this effort alone during last financial year.
3. Premise lighting of Central Hospital was being
predominantly achieved by HPSVs and MH street
lights which had very low energy efficiency on one
hand and were very voltage sensitive on the other.
On the basis of recommendations made in internal
energy audit, all street lights were replaced by
smart, energy-efficient LED lights. One LED based
high mast was also installed and number of HPSVs
was removed in lieu of it. This has resulted in
30.5% electricity saving in the last financial year.
4. Central Hospital was equipped with old fashioned water-chiller based
centralized air-conditioning plant of year 1989 genre which was very
inefficient energy-consumption-wise. Based on the recommendations of
internal energy-audit, it has been replaced by packaged type central air-
conditioning plant which is 24% more efficient when compared on the basis of
units consumed per sqft of cooling area.
5. Further, 21 No old and energy-inefficient split
and window air-conditioners have been replaced
with 5 Star rated energy-efficient air-
conditioners. This has resulted in immense
saving of electricity in the last financial year.
6. DG set installed to fulfill electricity need of
central-hospital was very old and energy in-
efficient due to continuous repair. It used to consume large amount of HSD oil
for catering full load. As an endeavour to continuously weed out non-efficient
equipments, same has been replaced by new 250 KVA DG set having MWM
engine of Greaves Cotton make. This has resulted improvement in specific
energy consumption from 0.38 to 0.30.
7. Occupancy sensors have been installed at strategic locations in the Central
Hospital to avoid unnecessary lighting-up of area in the absence of occupants.
These sensors are dual technology based, i.e. they work on infra-red and
ultrasonic principle simultaneously thereby avoiding spurious switching on/off
of targeted luminaries.
