How to distinguish the common application methods of inferior refrigerants —

The refrigerant is the blood of the compressor of the high and low temperature damp and heat test chamber. The purity of the refrigerant is particularly important for the compressor of the high and low temperature damp and heat test chamber. The most obvious phenomenon is: equipment filled with high-purity refrigerant , The refrigeration effect is obvious, the temperature drops quickly, and the refrigeration capacity is large; the low purity refrigerant not only fails to reach the expected temperature drop, but also damages the compressor. We can use the following methods to distinguish whether it is a low-quality refrigerant:

1. Whether to purchase a refrigerant produced by a regular manufacturer through a regular channel, such as a refrigerant whose price is significantly lower than the market price Refrigerants should arouse a high degree of vigilance.

2. If you have the test conditions, it is recommended to check the purity and acidity of the refrigerant before using it. It is not recommended to use the refrigerant whose test results are significantly lower than the industry standard.

3. If you do not have the refrigerant detection conditions, it is recommended to perform a simple inspection before using the refrigerant. The simple inspection method can be:

(1) Refrigerant The tank is turned upside down, and a small amount of refrigerant is released onto a piece of white paper. If there are obvious impurities or liquid water on the white paper, it means that the quality of the refrigerant is not good and it is not recommended;

(2) The pressure gauge is used to test the pressure of the refrigerant bottle. Compare the temperature and pressure characteristics table of the refrigerant to check whether the pressure in the bottle is within the normal range. If the pressure is obviously abnormal, it is not recommended.

If you are not buying the refrigerant through formal channels, you can check the authenticity through the brand’s official website. Fake and inferior refrigerants will not only affect the refrigeration effect, but seriously affect the equipment Normal use. Please purchase carefully.

With the signing of the Montreal Agreement in 1987, CFC refrigerants (such as R-11, R-12, etc.) have been completely banned due to their strong damaging effects on atmospheric ozone.
  Refrigeration network: The design of each air conditioner has the problem of how to determine the refrigerant charge, especially in the air conditioner that uses capillary tubes as throttling devices, because the capillary tubes have a higher regulating capacity The expansion valve is poor, and the change of the charge has a greater impact on its performance.
  【】Refrigerants are also called refrigeration working fluids, commonly known as refrigerants in some areas in the south.
As we all know, the power density of equipment in the computer room is high, so the volume heat is high.
  The air source heat pump is in winter heating conditions.
  【】Semiconductor cooling fins, also called thermoelectric cooling fins, are cooling devices composed of semiconductors.
   R22 and R410, which are commonly used in air conditioning and refrigeration, are two different refrigerants.
