How to choose the compressor and capillary of refrigerator and freezer

The compressor can be selected according to the compressor exhaust volume, because the length and thickness of the capillary tube is determined according to the displacement of the compressor, when replacing the compressor and replacing the capillary, it is necessary to pay attention to the length of the capillary, theoretically the capillary can not be less than 1.5 meters, this is because the evaporation pressure and condensation pressure caused by the influence of the environment change greatly.

Generally, a single capillary tube is used below the horse, and a double capillary tube should be used above the horse. The length of the capillary should also be determined according to the evaporation pressure of the refrigerant used, the refrigerator uses R12R134 without a professional flow tester, the capillary tube should be connected to the filter drier end of the refrigerator, add a high-pressure pressure gauge to open the compressor, the pressure to the kilogram per square centimeter can be, if it is too high, the capillary tube needs to be lengthened, but it is best not to connect.

The compressor, not to mention, is the heart of the refrigerator, and the choice of compressor depends on whether the capacitor is to be added, and there is no capacitor to protect. The capillary tube plays a throttling role, and the thickness and length of the original capillary should be paid attention to when choosing, and the thickness and length of different refrigerators are different.

The compressor pressurizes the refrigerant, the capillary tube throttles the refrigerant, and the press and capillary of the air conditioner and refrigerator are different.

Use three one-meter-long capillaries of a regular refrigerator and put them together.

Teach you the simplest: after the diameter capillary is selected, first choose 3 meters to access the system, connect the megameter on the filter, and card the ammeter on the compressor, and match the capillary and temperature according to the refrigerant you choose.

Everyone's approach is different, if you are from a professional background, you should know that the throttling selection of nuclear nuclei depends on the size of the press and the evaporation area. After you finish the management, the area has been changed to the potato economy, and it will sell so much, I am not afraid to teach you, I am afraid that my peers will beat me if I talk too much, hehe!!

Evacuation and refrigerant infusion.

The return air is not good, "How about the temperature of the compressor return pipe?" ”

And how about the current?

Generally speaking, the power of the compressor is larger.

You can tell you that 406 is a 12 system or a substitute for the production of the group, depending on the power or exhaust volume of the original machine.

If there is no nameplate, it will be more vague, so take it directly to the compressor and let the master see it.
