NEW QUESTION # 40
Which of the following statements regarding refrigerants is NOT correct?
5ELECT THE CORRECT ANSWER
Answer: A
Explanation:
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.
NEW QUESTION # 41
How can commissioning reduce the life-cycle cost to owners and operators?
Answer: D
Explanation:
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.
