Answer
The approved refrigerant for new household refrigerators, freezers, and combination units is **R-600a**.
Solution
The approved refrigerant for new household refrigerators, freezers, and combination refrigeration/freezers is:
**(D) R-600a**
**Explanation:**
- **R-600a (Isobutane):** This refrigerant is widely approved and commonly used in household refrigeration due to its high energy efficiency and low environmental impact. It has a low Global Warming Potential (GWP) and is a suitable replacement for more harmful refrigerants.
- **R-1234yf and R-1234zd:** These are Hydrofluoroolefins (HFOs) used in some refrigeration and automotive applications but are not as commonly approved for standard household appliances as R-600a.
- **R-170 (Ethane):** While also a hydrocarbon refrigerant with similar properties to R-600a, it is less commonly used in household appliances compared to R-600a.
**Therefore, the correct answer is:**
**D) \( R-600a \)**

Did you know that R-600a, also known as Isobutane, is not only eco-friendly but also incredibly efficient? It's becoming a favorite choice for many manufacturers because it operates with lower energy consumption compared to traditional refrigerants, ultimately giving your energy bill a break while being gentle on the environment! In real-world applications, households using R-600a can enjoy the benefits of quiet operation and better cooling performance. This refrigerant boasts zero ozone depletion potential and a very low global warming potential, making your fridge not just a food-preserving machine, but also a champion for sustainability!
