Combined heating & cooling - Heat pump - Ground-source - Warehouse

Template assignment

Base Case

• Small warehouse of 1,000 m²
• Heating load is 30.3 W/m², cooling load is 57.5 W/m²
• Electrically heated
• Cooled with a chiller, coefficient of performance is 3.00
• Electricity rate is $0.10/kWh

Proposed case

• Replace with a commercial ground source heat pump to meet all heating and cooling needs
• Assume the heat pump has a high coefficient of performance
• Incremental initial cost for complete system installation is estimated to $18,500 (this include $22,000 for the heat pump, $16,500 for the heat exchanger and a credit of $20,000 for the base case heating system)
• O&M savings are estimated at $2,200 per year
