2. Geothermal Technology
What is geothermal technology?
In a conventional system, the cooling tower of an
air conditioning plant sucks out the heat from an
enclosed space, and ejects it into the environment.
The technology GIBSS has designed uses instead
a heat exchanger system to deflect the heat into
the earth's crust. As the temperature just a few
meters below the earth's surface is much lower
than that of the air above, the energy transfer is
more efficient, reducing power consumption.
3. GEOTHERMAL HEAT IN
HYDERABAD
The Hyderabad-head-quartered Indian
School of Business (ISB) opened a new
campus in Mohali, near Chandigarh, on April
2015 . The air conditioning system in the
campus buildings, spread over 70 acres, has
been so designed as to save 1.2 million
kilowatt hours of power. The financial saving
on power alone will be Rs. 87.16 lakh
annually.
It will be a similar story at the Four Seasons
Hotel in Mumbai once its new air conditioning
system is installed. The hotel's monthly power
bill, currently over Rs. 40 lakh, is expected to
drop to Rs. 10 to 15 lakh.
11. Considering bank loan repayment rate of 10%
Now,
P=A[(1+i)n-1]/[i(1+i)n]
P=A[
(1+0.1)20−1
(1+0.1)20 ]
A=P/8.5
A=502000/8.5
A=59058.82
12. Now,
In the first year we will be taking a loan of
502000*200/10= 10040000
In the second year loan of
502000*300/10= 15060000
In the 3rd year loan of
502000*400/10= 20080000
In the 4th year loan of
502000*400/10= 20080000
LOAN CALCULATION
13. • Average monthly electricity bill=4000
• Efficiency of our heat pump in rate cutting= 40%
• Customers shall pay 75% of their savings on monthly basis
• Monthly revenue r = (75/100)*(40/100*4000)= 1200
• Now,
• R1= (1200*200)*12= 2880000
• R2= (1200*300)*12= 4320000
• R3= (1200*400)*12= 5760000
• R4= R4= R5= R6= R7= R8= R9= R10= 5760000
