NEW QUESTION # 12
Which of the following statements regarding refrigerants is NOT correct?
5ELECT THE CORRECT ANSWER
Answer: D
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 # 15
According to the institute of Electrical and Electronic Engineers (IEEE) standard 519. "Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems." the maximum total harmonic distortion (THD) for general low voltage systems less than 600 votts) should be:
SELECT THE CORRECT ANSWER
Answer: D
Explanation:
The Institute of Electrical and Electronics Engineers (IEEE) Standard 519, titled "Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems," sets forth guidelines to maintain the quality of electrical power by limiting harmonic distortions. According to IEEE 519, for general low-voltage systems (defined as systems with a voltage less than 600 volts), the Total Harmonic Distortion (THD) of the voltage waveform should not exceed 5%. This threshold ensures the reliable operation of electrical equipment and minimizes potential issues such as overheating or malfunctioning caused by excessive harmonics.
Therefore, the correct answer is C. Less than 5%.
NEW QUESTION # 16
A desk lamp is located inside a windowless office. The office is heated during the winter and cooled during the summer. When the lamp is switched on, how much of the energy consumed by the lamp becomes heat in the office space?
Answer: C
Explanation:
* All electrical energy consumed by the lamp is converted into heatwithin the space, either as direct heat or as waste heat from the light source.
* In a windowless office, no energy escapes as light.The light energy that is emitted eventually turns into heat through absorption by surfaces.
Thus, the correct answer isC. 100%.
