Yes! We have a ton of independent data to suggest that using a CoolBot with a window air conditioner or a ductless mini-split air conditioner is more efficient than a conventional refrigerator compressor.
We've had hundreds of customers give us feedback about their lower electricity bills versus the conventional refrigerator compressor they used to have.
Additionally, NYSERDA, (the NY State Energy Research and Development Authority) contracted for an independent analysis to measure the efficiency of a CoolBot-driven system versus a standard cooler.
The 35 page NYSERDA study confirms that the CoolBot works great and does not stress out the air conditioner or push it into unacceptable cycle times (which is another question that we get asked a lot). NYSERDA found that a CoolBot-driven system is about 40% more efficient than a conventional refrigerator.
Although the CoolBot-driven system is typically oversized versus a conventional cooler from a BTU perspective, it saves so much energy as an air conditioner typically uses only one 300 watt fan, while a conventional refrigerator compressor uses 3, 4 or 5 fans, depending on the size. One major benefit to a one-fan system is that certain flowers and crops (e.g. delicate flowers or baby lettuce) will stay fresher for longer due to the reduced air movement in the cooler. The tradeoff is that our recovery times back to the desired temperature can be slower than a conventional compressor if the door is left open and the cool air is allowed to escape. If you can be judicious about not leaving the door open, we think you will save a bundle of money with the CoolBot.
