Heat Pumps For Energy Efficient / Economical Hot water Generation Hotel at Udaipur

Lets have a look at the basic parameters

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

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)

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

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

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

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. 15.75 Lakhs/year

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

Payback period in months CAPEX of Heat Pump system x 12 Annual OPEX savings 18,00,000 x 12 15,75,000 13.7 months 14 months
