Template assignment

Base case

• 2,500 m² building with 100 kW reciprocating compressor chiller
• Chiller has a seasonal coefficient of performance of 3.5
• Cooling load for building is 40 W/m²
• Electricity rate is $0.085/kWh

Proposed case

• 100 kW rotary compressor chiller costing $7,000 more than the base case system
• Chiller has a seasonal coefficient of performance of 5.0
• Maintenance requirements are lower than in base case by $300/year
• Capacity charges (demand charges) are lower than in the base case by $100/year
