問題 #17
If the temperature difference across an external wall is 20°C and the heat flow across the wall is 2.5 Watts/m², calculate the insulation value of the wall (including inside and outside air films)?
答案：D
問題 #18
If a boiler cycles on and off too frequently, what control can you adjust to reduce the number of times a boiler cycles on and off?
答案：A
問題 #19
How can commissioning reduce the life-cycle cost to owners and operators?
答案：B
解題說明：
1) Life-Cycle Cost Reduction via Commissioning (CEM Guidance)
The AEE CEM Body of Knowledge emphasizes that commissioning reduces total life-cycle cost, not just first cost, through multiple pathways.
2) Evaluation of Each Option
* A. Reduce the cost of change orders during construction
* Early detection of design and coordination issues reduces rework.
* B. Improve the performance of energy systems
* Ensures systems operate at intended efficiency.
* C. Improve the satisfaction of building occupants
* Better comfort reduces complaints and operational disruptions.
* D. Improve the effectiveness of operations and maintenance
* Training and documentation improve long-term reliability and efficiency.
All are documented commissioning benefits in AEE CEM training materials.
問題 #20
Which of the following statements regarding refrigerants is NOT correct?
5ELECT THE CORRECT ANSWER
答案：E
解題說明：
Understanding the environmental impacts of various refrigerants is crucial for energy managers. Let's analyze each statement:en.wikipedia.org A). R-407C is a blended Hydro Fluoro Carbon or near Azeotropic mixture, and can be used as a replacement for R-22 in commercial applications:
This statement is correct. R-407C is a blend of HFCs designed to replace R-22 in air conditioning systems.
B). R-11 and R-12 are Chloro Fluoro Carbons with significant ozone depleting potential:
This is correct. R-11 and R-12 are CFCs known for their high ozone depletion potential.
C). R-1234yf is a Hydro Fluoro Olefin with zero ozone depleting potential, and little global warming potential:
Correct. R-1234yf is an HFO with negligible ozone depletion and low global warming potential.
D). R-22 is a Hydro Chloro Carbon with significant ozone depleting potential and significant global warming impact:
This statement is incorrect. R-22 is a Hydrochlorofluorocarbon (HCFC), not a Hydro Chloro Carbon. While it does have ozone-depleting potential, its global warming potential is considered moderate, not significant.
E). R-32 and R-134a are Hydro Fluoro Carbons with zero ozone depleting potential, and significant global warming impact:
This is correct. Both R-32 and R-134a are HFCs with no ozone depletion potential but have considerable global warming potential.
Conclusion:
The incorrect statement is D. R-22 is a Hydro Chloro Carbon with significant ozone depleting potential and significant global warming impact. Therefore, the correct answer is D.
