The unit is operated 120 days each year for 8 hours per day (960 hours per year), and the electric energy cost is $0.10 per kilowatt-hour. What is its annual cost of operation in terms of electric energy? First, we convert tons of cooling to BTU/h: (4 tons) × (12,000 (BTU/h)/ton) = 48,000 BTU/h. The annual cost of the electric energy is:
