1
Heat Pumps For Energy Efficient / Economical Hot water Generation
Hotel at Udaipur
2
Lets have a look at the basic parameters
3
Basic parameters at Hotel at Udaipur
Cost of Power Cost of diesel Temperature to be raised from Average Diesel consumption for Hot Water Generation 135 Liters/day 20°C to 50°C Rs. 8 per KW Rs.50 per litre
4
Energy Required = 9,00,000 Kcal/day Energy required in KW = 1047 KW
Total Hot Water Consumption = 30,000 Liters/day Energy Required = 9,00,000 Kcal/day Energy required in KW = 1047 KW Operating time = 6.5 hours 30,000 x (50°C – 20°C) 9,00,000 / 860 ( 1 kW = 860 kCal ) 1047/160 kW (heat pump)
5
Power Consumption for 2 x 80 KW
Selection of Heat Pump Heating capacity 80KW x 2 Energy required in kW 1047 KW/day Operating hours 6.5 hrs Power Consumption for 2 x 80 KW 46 KW
6
OPEX cost of Heat Pump 46 KW 6.5 hrs/day Rs 2392 per day Rs 8/KW
Net power consumed Operating time Cost of electricity Rs 2392 per day 46 KW 6.5 hrs/day Rs 8/KW Rs 8,61,120 per year
7
OPEX cost of HSD fired HWG
HSD consumption/day Cost of HSD/ltr Rs 6750 per day 135 liters/ day Rs 50 Rs 24,30,000 per year
8
Savings in OPEX with Heat Pump
Operational cost of Gas fired boiler Rs 24,30,000/yr Operational cost of heat pump Rs 8,61,120 /yr Total Savings Rs 15,68,880/year Say Rs Lakhs/year
9
CAPEX of Heat Pump system
Rs 18,00,000 /- Interface Accessories Rs. 4,00,000 Heat pump Rs 14,00,000 Total cost of heat pump system
10
Payback period in months
CAPEX of Heat Pump system x 12 Annual OPEX savings 18,00,000 x 12 15,75, months 14 months
