In cooler climates how can a new building be designed to use no refrigerants?
A: The building could be cooled with natural refrigerants such as propane or ammonia
B: The building could use natural ventilation
C: The building could use halons for cooling
D: The building could have a CFC phase-out plan in place

参考答案: B

本题解释:
Notes:
A:Natural refrigerants are still refrigerants.
B:The no refrigerant option for buildings can be achieved with natural ventilation. Natural ventilation can be done in cooler climates where ventilation can be provided by opening windows or using fans to pull in outside air to cool the building. Using refrigerants requires mechanical ventilation.
C:Halons are primarily used in fire suppression.
D:With a CFC-phase out plan you are usually replacing one refrigerant with another, not going from mechanical to natural ventilation.
