The refrigerant is the blood of the compressor. The purity of the refrigerant is particularly important for the cold storage refrigeration equipment. The most obvious phenomenon is: the cold storage filled with high-purity refrigerant, the cooling effect is obvious, the temperature drops quickly, an... read more
It is reported that the new national standard combines the energy efficiency of the original fixed frequency and inverter air conditioners, and the energy efficiency level has also been expanded from the original 3 to 5. Industry experts said that after the standard upgrade, the energy efficiency in... read more
The refrigerant is the heat transfer carrier in the refrigeration cycle. It absorbs and releases heat through state changes.
