How To Add Fluorinated Solvent

  • Can fixed frequency air conditioner add r410a?

     

      Fluorinated Solvent R410A mixed refrigerant, which is a mixture of R32 (difluoromethane) and R125 (pentafluoro) according to certain examples, and the evaporation points of the two are different. so. If the air-conditioning pressure is lower than one-third of the normal pressure, the ratio of the two refrigerants is too large, and all of them must be discharged. Re-evacuate and add fluoride.

     

      The benefits of substituting R22 refrigerant


      (1) R410A is of low toxicity, R22 is slightly toxic, and it will be more secure in terms of safety in use.

      (2) For environmental hazards, the ozone layer destruction coefficient of R410A is 0, and the ozone layer destruction coefficient of R22 is 0.05. So R410A refrigerant has more advantages.

      (3) When using R410A, the total heat transfer characteristics of the system are larger than R22, so the system efficiency can be improved and the heat transfer area of ​​the heat exchanger can be reduced. The air conditioner is more smooth to use, and the chance of failure is much smaller.

      In the later use, it is mainly added according to the refrigerant model on the air conditioner. Do not add it randomly, which may cause damage to the air conditioner and personal danger. Of course, the later development of air-conditioning refrigerants will continue, and there will be better alternative products to replace them. At present, R410A refrigerant is the mainstream of future development. The market prospects will also get bigger and bigger.

      Can Heptafluoropropane HFC-227EA be replaced by r22?

      To tell the truth, it is okay. Nowadays, people who repair air conditioners do it like this. However, replacement is not recommended. R22 is generally used in fixed-frequency air conditioners, and R410a is used in inverter air conditioners. R410a is still mixed, if it is directly replaced, it will have a great impact on the compressor. R410 is a bit more expensive.
