Detailed Description
Embodiments of the intelligent fluorine-free refrigerator of the present invention will be described in detail with reference to the accompanying drawings.
The fluorine-free refrigerator is a statement that people often hear in publicity words of merchants, and in fact, the fluorine-free refrigerator is not fluorine-free, so that the statement is very unscientific. Experts point out that none of the fluorine stems from "no freon" which was later reduced by people to "no fluorine". Freon destroys the ozone layer, so that people have a missense that the freon destroys the ozone layer. In fact, the destruction of the ozone layer is caused by chlorine atoms contained in refrigerants, foaming agents, fire extinguishing agents and cleaning agents which are widely used at present, and is unrelated to fluorine atoms. Many of the currently developed substitutes for ozone depleting substances contain fluorine, and the absence of ozone depletion by these substitutes is not due to the absence of fluorine, but to the absence of chlorine.

In addition, the CMOS sensing device is an active pixel sensor. An Active Pixel Sensor (APS) is also called an Active Pixel Sensor. Almost simultaneously with the invention of the CMOS APS pixel structure, it was quickly recognized that the performance of the pixel could be improved by introducing buffers or amplifiers within the pixel, with its own amplifier within each pixel in the CMOS APS. The amplifying transistor integrated on the surface reduces the effective surface area of the pixel element, reduces the packaging density and enables 40% -50% of incident light to be reflected.
