Base case
- Continuous heating load during operation of 2 million Btu/h
- Continuous cooling load during operation of 100 refrigeration tons
- Electrical load of 100 kW is on 75% of time that electrical systems operate
- Heating system fed by boiler that runs with diesel (#2 oil) and operates 45 h/w at 70% seasonal efficiency
- Cooling system runs 12 h/d, and the refrigeration system has a seasonal COP of 3.0
- Electrical equipment runs 200 h/m
- Heating load reduced by 10% with a duty cycle of 90%, operating hours cut to 40 h/w
- Cooling system duty cycle reduced by 10% and operating hours to 10 h/d
- Electrical equipment load and operating hours reduced by 10% and duty cycle reduced to 70%
- Incremental costs for heating system: $100,000; for cooling system: $10,000; for electrical equipment: $5,000
- Annual operational savings due to improvements estimated for heating system: $1,000; for cooling system: $100; for electrical equipment: $100
- Change heating fuel to natural gas at 80% efficiency
- Lease a new refrigeration system with seasonal COP of 3.5
