10. AMMONIA ABSORPTION CHILLERS
G
• A set of eco-friendly chillers run on R
LPG and require minimum energy
9kw. E
E
• As LPG is non-renewable sources of
energy so efforts are made to run N
the chillers on producer gas
generated by wood burning gasifires.

• For conference hall of 100 people
temperature requires less than 25
U
degree Celsius which can be attained I
by these chillers.

14. BIOMASS GASIFIER SYSTEM G
R
The biomass gasifier is the main source of
power during the day E
Apart from fuelwood, the gasifier can also use
straw, small twigs and branches, and other
E
crop residue. To make such fuel easy to handle, N
it is chopped into small pieces which are
pressed together to form compact cakes or
briquettes. The 50-kilowatt gasifier runs a B
generator, whose diesel requirements have
been cut down to 30% after appropriate U
modifications; the rest of the fuel comes from I
the gasifier in the form of producer gas. One
unit of electricity produced needs 1 kg biomass L
and 90 ml of diesel. D

15. Photovoltaic panels G
Solar water heater taps the suns energy directly, a R
series of photovoltaic panels capture the energy
and store it by charging a bank of batteries. A E
number of panels, each measuring 1.1 by 1.2 E
metres, are joined and form an integral part of the
roof of the building. The panels can generate up N
to 10.7 kilowatts peak of energy, which is fed into
a 900 ampere-hour/240 volt battery bank.
Independent panels power most of the lights B
located outside the building. Each such light has a
pair of small photovoltaic panels (roughly a metre U
wide and half a metre tall) and is thus a self- I
sufficient stand-alone unit.
The sun is the powering force of RETREAT, where L
Photovoltaic panels also run a water
solar panels are used to form a 'solar roof' pump D
