質問 2：
A gas-fired boiler is operating with 31.9% excess air. A feedwater economizer is used to reduce the stack temperature rise from 310°C to 160°C. Using the natural gas combustion efficiency tables in your workbook, find the energy savings from the economizer as a percentage of historical fuel consumption.
A. 5.8%
B. 7.1%
C. 3.1%
D. 1.2%
E. 9.3%
正解：A
質問 3：
A refrigerant-to-water heat exchanger can be added to air-conditioning equipment to heat water using the waste heat in the vapor compression refrigerant cycle. Where is this type of heat exchanger located in the refrigerant loop?
A. After the evaporator coil, before the compressor
B. After the condenser coil, before the thermal expansion valve
C. After the expansion valve, before the evaporator coil
D. After the compressor, before the condenser coil
正解：D
質問 4：
How can commissioning reduce the life-cycle cost to owners and operators?
A. All of the above
B. Improve the satisfaction of building occupants
C. Improve the effectiveness of operations and maintenance
D. Improve the performance of energy systems
E. Reduce the cost of change orders during construction
正解：A
質問 5：
A concentrating solar thermal system collects 5 GJ/h of thermal heat, which is delivered to a 94% efficient hot water generator. The hot water generator is used to raise the water temperature from 15°C to 65°C. The specific heat of water (Cp) is 4.2 kJ/kg-°C. What flow rate (liter/second) of hot water can be delivered from the hot water generator?
A. 6.2 liter/second
B. 4.2 liter/second
C. 12.0 liter/second
D. 9.2 liter/second
正解：D
