Answer
The refrigerant with the lowest Global Warming Potential is **R-600a**.
Solution
The refrigerant with the **lowest** Global Warming Potential (GWP) among the options provided is:
**(B) R-600a**
Here's a brief overview of each refrigerant's GWP:
- **R-134a**: GWP of approximately **1,430**.
- **R-600a** (Isobutane): GWP of around **3**.
- **R-410A**: GWP of approximately **2,088**.
- **R-407C**: GWP of approximately **1,774**.
**R-600a** is not only efficient but also has a minimal impact on global warming, making it a more environmentally friendly choice compared to the other listed refrigerants.
**Answer:**
**B) R-600a**

Simplify this solution The Deep Dive
R-600a, also known as isobutane, has the lowest global warming potential of the refrigerants listed. Unlike many synthetic refrigerants, R-600a is a natural hydrocarbon that boasts a much lower GWP and is more environmentally friendly, making it a preferred choice for eco-conscious refrigeration applications. When considering refrigerant choices, it's crucial to look beyond just the GWP. Real-world application also involves safety measures, as some refrigerants, like R-600a, are flammable. Proper leak detection and ventilation can help mitigate risks, ensuring a safe and efficient refrigeration system while benefiting the environment.
