What do you think of the snow table? What do you think of the schematic diagram of the automobile snow gauge?

Whether adding snow species or detecting supercharging, all the work related to automobile air conditioning can not be separated from the snow species table. So how do snow watches read degrees? Let's have a look. About the snow platform? Snow gauge is mainly composed of three pipes and two pressure gauges. Generally, the pipeline and pressure gauge on the left are blue, which corresponds to the low-pressure pipeline of air conditioning. The right pipe and the pressure gauge are red high-pressure pipes corresponding to the air conditioner; The yellow tube in the middle is usually used to connect the refrigerant tank or vacuum pump. There will be two pressure valves between the two pressure gauges and the left and right pipelines to control the communication between the two pressure gauges and the middle yellow pipeline (when the valves are normally closed, the blue instrument is connected to the blue pipeline and the red instrument is connected to the red pipeline). What do you think of the degree of snow regulation? Generally speaking, the innermost scale of the snow species table indicates that the saturation day of the snow species at the current air pressure is℃. When reading, we can only read the numbers on the saturated temperature scale corresponding to the pointer. Of course, it should be noted that the measured snow type must be the same as that marked on the snow type table, otherwise the results will be biased.
