Is refrigerant carbon monoxide, snow comes in several colors

The answer may not be correct, you can go and ask the teacher.

Carbon monoxide can be in snow, and refrigerant can also be carbon monoxide.

For details, you can check the encyclopedia introduction.

Snow is the solidification of water, and there is only one color, and that is white. However, sunlight is made up of many kinds of light, and snow will reflect it, depending on the angle you are looking at**.

White, there are other colors because of impurities or light problems.

Normally, there is only one kind: white.

But if it's time for the sun to set: the snow turns red.

It mainly depends on what angle, when, and position you look at.

The refrigerant (refrigerant) required for a 2hp household wall-mounted air conditioner will not exceed 2kg;

R22 refrigerant, the cost price is 12 15 yuan kg, and the cost of adding one time will not exceed 120 yuan;

R410A refrigerant, the cost price is 20 40 yuan kg, and the cost of adding one time will not exceed 200 yuan;

Now the most commonly used is R134, and the R12 is no longer useful.

At present, there are the following six models of the American Rubber Qiaoqiao National Car Baoxue:

1. Ammonia (code: R717).

2. Freon Kuanzheng-12 (code: R12).

3. Freon-22 (code: R22).

4. R-134A (code: R134A).

5. R-404A refrigerant.

6. R-410A is a refrigerant for making beams.

The process of disassembling and assembling the air conditioner:

Dismantling the air conditioner: one. In the refrigeration state: Open the covers of the two connecting pipe valves of the outdoor unit with a wrench.

With five hexagon wrenches, I put in the thin (high-pressure valve) valve port and close the valve quickly, and after about 20 seconds, I close the thick valve (low pressure) and shut down and cut off the power. In this way, the fluorine is received from the outside machine. In this way, the machine can be disassembled.

Air conditioning: two. When installing, there is also an open valve to empty: the details are as follows:

After fixing the inner and outer units, 1To connect the air conditioner well, the main thing is to tighten the connecting pipes of the internal and external units, and pay attention to the connection to prevent refrigerant leakage.

2.Use the hexagon switch to hit the automatic air conditioner to open the high-pressure valve (thin pipe valve) normally, and use the hexagon to resist the fluoride port thimble (the fluoride port is on the low pressure), so that the gas inside can run out, about 10 seconds, not too long, so as not to run too much. This allows the air inside the line to escape.

4.Then open the valves of high and low pressure, and connect the power cord of the internal and external units.

Note: The connecting pipe is copper, and it cannot be coiled into a dead bend, otherwise it will affect the flow of refrigerant, resulting in the inability to cool and heat.

If you can't get it yourself, try to find a professional.

The refrigerator should be filled with an appropriate amount of refrigerant, not the more the better. If it is charged too much, it will increase the burden on the compressor, which is not good for the compressor, and may also cause non-stop failure. If there is too much refrigerant, the compressor return pipe will frost, and if the refrigerant is too small, the refrigeration effect will not be good.

Generally, it is charged with 1 kg of pressure in summer and kg of pressure in winter, and it is enough to feel cold when you touch the compressor back pipe.

If it is charged too much, it will increase the burden on the compressor, which is not good for the compressor, and may also cause non-stop failure. If there is too much refrigerant, the compressor return pipe will frost, and if the refrigerant is too small, the refrigeration effect will not be good.

The R22 refrigerant used by our company is Shenzhen Shuangfeiyan, you can try it!
