R407c Refrigerant Replacement Related Matters
There is a matter of refrigerant R407c replacement today, which is related to refrigerators, and it is very important. R407c is unique in nature and has its specific performance in refrigeration systems.

The need for replacement at present is due to the evolution of refrigeration technology, or the inadequacy of the old refrigerant, or in accordance with new environmental regulations. When replacing R407c refrigerant, the structure and material of refrigeration equipment must be carefully inspected. Different equipment has different adaptations to R407c.

First check the system seal, and be sure to fit tightly to prevent R407c leakage. If R407c leaks outside, it will damage the refrigeration effect, and the second may cause harm to the environment. The second inspection of the compressor, this is the cardinal of the refrigeration system. Whether it can adapt to R407c is related to the stability of the system operation. If the compressor cannot withstand the working conditions of R407c, it will fail, or even cause the system to be paralyzed.

And the charging amount of R407c must also be accurate. If there is too much, the system pressure will be too high, and if there is too little, the cooling will be insufficient. When charging, when strictly measuring according to the specifications and working conditions of the equipment, it must not be careless.

Furthermore, after replacement, the system parameters need to be adjusted. Indicators such as temperature and pressure should conform to the characteristics of R407c. After fine adjustment, the refrigeration system can reach the best operating state, so as to achieve the effect of efficient refrigeration, and can prolong the life of the equipment and save energy. This is the key to the replacement of R407c refrigerant, and the operator should be cautious and follow the rules before it can be achieved.
