I've never heard of magnetic refrigeration, I know that there's a process that uses shock waves to cool stuff, and onother that uses them to heat, but the better word for that is sonic, not acoustic.
Go on the internet. Search separately for "acoustic refrigeration" and "magnetic refrigeration". Acoustic refrigeration works. Magnetic refrigeration works. Read about it. JMG.
Magnetic refrigeration is used for cryogenic temperatures. A non-cryogenic magnetic refrigerator was made for regular home refrigeration needs; however, it needed to be turned on all the time as opposed to standard refrigeration involving a refrigerant flowing through pipes. That residential model never made successful entrance into residential refrigeration markets. Acoustic refrigeration is based on themoacoustics. Acoustic refrigerators operate fairly efficiently and outperform magnetic refrigeration for residential refrigeration needs. However, there are always new compounds for magnetic refrigeration and it is possible that magnetic refrigeration may be better than acoustic refrigeration for residential refrigeration needs at some point in time. The purpose of my posted query for this thread is to learn about new information in these areas. New information changes the perspective of what refrigeration technique is better than the other. New information from others might change my perspective on the answer to my question. Your post provides no useful knowledge from which to learn from. JMG.
In the recent past Ames Laboratory researchers did a study wherein modern magnetic refrigeration is about 20% more energy efficient than traditional cooling systems. Their press release is: http://www.ameslab.gov/News/release/crada.html They did not compare magnetic refrigeration against acoustic refrigeration. JMG.
Next time, try asking what you wanted to know. You'll acheive much better results if you do this and state what you already know.
My original question stated clearly my inquiry which remains unanswered by another person. The depth of which I disclose knowledge on a topic has its limits. In this example I sought knowldge. In the soda example I was humored by the responses which neglected latent heat. How much knowledge do you suggest is necessary as an appendix to a question so that it may be answered? The fundamental equations for said question or websites on said question? JMG.
It seems that the full name of the process is thermoacoustic, and the process I had heard of previously sounds similar. They could eb the same thing.
