LOAD CALCULATIONS - BASICS
Load Calculation
CALCULATION TYPES:
Through litres per day of water
• Canteen & Boiler Feed water application
Through Fuel Consumption
• Process heating & washing machine applications
Through Litres per day of Water
Q = m x Cp x ΔT
Canteen & Boiler feed application
Q = Energy required (kW)
m = Mass flow of water in LPD
Cp = Specific heat of water (kcal/kg K)
ΔT = Temperature difference (deg C)
Example:
10000 LPD has to be raised
from ambient to 80 deg C
Q = 10000 x 1 x (80 – 30)
= 500000 kcal
= 500000/860
= 581 kWh per day
Through Litres per day of Water
LOAD ESTIMATION FOR HEAT PUMP SYSTEM
Effective working hours = 16 - 18 hours per Day
Heat Pump Capacity =
𝐓𝐨𝐭𝐚𝐥 𝐄𝐧𝐞𝐫𝐠𝐲 𝐑𝐞𝐪𝐮𝐢𝐫𝐞𝐝 𝐩𝐞𝐫 𝐝𝐚𝐲
𝐄𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞 𝐖𝐨𝐫𝐤𝐢𝐧𝐠 𝐇𝐨𝐮𝐫𝐬
= 581/16 = 36 kW
TYPE - 2 Thru Fuel Consumption
Amount of Fuel consumed by the Boiler?
Boiler Efficiency?
Example:
Average Fuel consumed by the boiler per hour = 10 Litres of Diesel
Calorific value of Diesel = 11 kW per litre
Total energy = 110 kWh of Energy
With Boiler efficiency of 70%,
the effective Output per hour = 110*0.7 = 77 kW

Load Estimation
Fuel Consumed per hour = 9 kg/hr (during peak load)
Calorific value of LPG = 12.8 kW/kg
Boiler Efficiency = 70%
Energy required for process = Fuel Consumption * Calorific value * Boiler efficiency
= 9 * 12.8 * 0.70 = 80.64 kW
Total Energy required for one hour = 80.64 kW

TESTIMONIALS
The crowning glory of the UNDP
GSWH Program… an undisputed
example of a win-win situation for
client and the ESCO…marks the
beginning of a new chapter in
energy savings by industries through
the ESCO route.. would help the
industries in fulfilling their
renewable purchase obligation and
reduce the consumption of an
expensive fossil fuel. I expect all
forwarding looking companies would
embrace what Aspiration Energy has
demonstrated.
