A while back we wrote about the performance of our refrigerator and presented the power details. However, one item was probably missing in the data. That is, how much power does that thing take when its summer?
I pulled out our trusty Kill-o-watt power monitor and set up the test a couple days ago, and began recording . Unfortunately, we are not in the middle of a hot spell which would raise the ambient temperature in in the kitchen to 80F or more. For this test I’d say the average temperature remained between 70-72F. This is better described as a middle temperature data point, but more information will always help others decide if this is right for them.
Here are the test conditions:
- Frigidaire 18 cubic foot freezer/refrigerator (ice maker not used)
[ Label inside reads Electrolux model FRT18IL6JW1 ]
- Measurement time of 39.5 hours. Timer has unit off 7hrs at night.
- Power measured was 640 Watt Hours total. 115-130W when compressor running, 44W light when door open.
- Test conditions: “Normal” family of 4, 2 adults, 2 teens. Kitchen temperature mostly 70-72F its a cool summer spell.
- Primary power is the output from our Modified Sine Wave Inverter, a Trace DR2412.
The total power was 1470 WH, and that averages out to 893 WH per day. Compare that to 640 WH from the winter measurment and there seems to be a big difference. Still this number is far better that the 3120 WH per day with 100% duty cycle.
There are probably human factors involved here. I didn’t puppy guard the refrigerator door to “monitor” its use this time. That may have resulted in the door being open more. In fact, Jackie made a delicious pie yesterday using the leftover apples and fruit in the fridge. She was trying to clean out the fridge for next week when we’re gone mostly to the county fair with the kids 4H projects. Yep, that’s it. We’ll be back again on this one to get a better data point for comparison.
The lesson from this number is clear, don’t leave that fridge door open, you’re spilling power all over the floor!
