Ice magnetic refrigeration fan is a new type of fan based on magnetic cooling technology, which realizes cooling effect through the heat absorption\/release process generated by magnetic field changes. This technology is theoretically feasible, but most of the current popular fans still use traditional compression refrigeration technology. At present, there are some fan products that claim to use ice magnetic refrigeration technology on the market, but whether the authenticity and effect of these products are as advertised needs to be evaluated according to the quality and performance of specific products, as well as the actual use experience and evaluation of consumers. In short, the concept of ice magnetic refrigeration fans exists scientifically, but there are relatively few practical applications and widely recognized products on the market, which need to be carefully selected and evaluated.
