No matter where you look people are trying to save on their energy bills. Over the last few years, some very innovative green minded individuals have started giving up artificial refrigeration to do their part, this can be done by digging holes to a point that will have a consistent temperature of about 45 degrees Fahrenheit. This would save on average of a few hundred kilowatt-hours every year. But this isn’t going to get a large enough interest, and its really impractical for most to ever make an actual difference, although it is commendable, we need to keep looking for the future in green refrigeration.
The answer to this question lies in solar energy and riding the waves of the green phenomena that is sweeping the country. Solar energy, often known as photostatic is ubiquitous these days. Some use solar to power their homes others buy carbon offsets that put money into solar and wind energy to offset their traditional energy usage. Solar panels sit on buildings roofs and homes to your cell phone charges, our blenders and everything in between we might use in our daily lives. When Sunlight strives a PV cell, it heats up said cell. Heating of the cell necessitates a process where in heating up the cell causes electrons to knock loose, and these electrons are thus converted into a stream of electricity and or current.
On of the appliances that is leading the way for going green and actually makes a large difference given its massive power requirements in your refrigerator. The fridge, that was developed for the international space station was the brain child of a couple of scientists who decided the technology would do well here on earth. Thus the solar refrigeration arms race began. What they developed is called the SunDanzer refrigerator which works a lot like a traditional fridge. It uses a vapor compressor for cooling. Essentially, a refrigerant gas like Antonia is compressed down, and placed under pressure which causes it to get hot: as it cools back down to normal, it condenses into a liquid. When this liquid travels to a lower pressure area, it expands, thus creating a vapor. This vaporization process, adsorbs, the heat and cools the coils of your refrigerator.
When you consider the energy requirement of this on an energy demand of a standard grid and convert it to a solar system, you are safe to assume you are going to need about 5 hours of day light to produce sufficient cooling for the unit. This is no easy task, and no matter where you are not always feasibe. The way to rectify this is allow for batteries to be a part of the system that can store energy on higher than average sun days. Another thing that will need to happen given the state of the technology is that you are going to need it to be connected to your traditional grid in order to meet the need and ensure you are never left in the dark. But if you consider that you could reduce not all of your energy to the refrigerator but most you are still going to feel significant savings in your energy bill.
