EER is the energy efficiency ratio. Or simplicity, use the minimum EER for a closed loop, water to air closed loop heat pump 16.1 3.6 17.1 21.1 12 This question is in regards to ground source (geothermal) heat pumps only From the previous question, determine the minimum COP for a ground source/geothermal heat pump (closed loop, water to air closed loop) 1.1 5.0 4.7 6.2 13 This question is in regards to ground source (geothermal) heat pumps only. Using the minimum COP for the refrigeration/cooling cycle for an ground source heat pump (Q11) and a cooling/refrigeration capacity of 10 tons of refrigeration, what is the power input requirement (in kW) for a ground source (geothermal) heat pump? 5.18 7.01 8.18 10.98 14 This question is in regards to ground source (geothermal) heat pumps only. Using the minimum COP for the refrigeration/cooling cycle for a ground source (geothermal) heat pump (Q12), the power input requirement calculated in Question 13, and an electricity cost of $0.13/kWh, how much will a ground source [geothermal) heat pump cost to operate for 10 years? (For simplicity, let's say you estimate that the unit will be running 12 hours per day) $24,842 $39,931
