A project has four HVAC&R units on the roof of the building. One of the units exceeds the
allowable refrigerant charge for EA Credit 5. What will allow the project to earn EA Credit 5
Enhanced Refrigerant Management?
A: Average the refrigerant charge across the four units
B: Exclude the unit from the calculations
C: Include a phase-out plan for the out of range unit
D: Replace or fix the out of range unit so that it complies with the allowable charge requirements

参考答案: D

本题解释:
Notes:
Reference: O&M Reference Guide, EA Credit 5, Implementation
Equipment that uses natural refrigerants is eligible for EA Credit 5.
Averaging the units is not allowed; the unit must be replaced or fixed.
A phase-out plan is needed for EA Prerequisite 3, not EA Credit 5.
