The operation and use of solar air conditioners.

There are currently three forms of solar air conditioners. The first is to use solar panels to convert into electrical energy and then use a small air conditioner with a DC compressor for cooling and heating. The second is to use lithium bromide. endothermic unit and an evacuated tube solar collector. The water heater heats water and uses a bromine machine for cooling and heating. The third method uses a semiconductor PN junction for cooling and heating, and converts cold into natural current through electrodes that convert direct current. All three types have formed products, but they have different uses.
