Refrigerant used by Emerson Copeland compressor

Refrigerant used by Emerson Copeland compressor With the global emphasis on environmental protection, our refrigeration industry is also the same, and gradually use some environmentally friendly refrigerants. Previously, the refrigerant used by Emerson Copeland compressors was R22, and R22 was not an environmentally friendly refrigerant. Later, Emerson Copeland Compressors gradually changed the compressors to use environmentally friendly refrigerants. When we look at the model of Copeland compressor, we can see what refrigerant this compressor should use. If you see E in the model of Emerson Copeland compressor, then this compressor uses environmentally friendly refrigeration oil. Of course, this compressor also uses environmentally friendly refrigerant. (Environmental refrigeration oil can also use environmentally friendly refrigerant. R22 refrigerant can be used). On the contrary, we don't see the E word in Emerson Copeland compressor, then Copeland compressor. Normal refrigeration oil is used, so R22 refrigerant is also used. (Compressors using R22 refrigerant cannot use environmentally friendly refrigeration oil). Emerson Copeland Air Conditioning compressors add refrigerant to the scientific method, we first use the current method. Emerson Copeland compressor air conditioner compressors have corresponding rated currents. Clamp an ammeter on the Copeland compressor input mains wire to connect the refrigerant and compressor low-pressure port. Remember to use refrigerant to drain the connection pipe. For air, first use the pressure of the refrigerant to add fluoride statically, and observe the liquid condition in the oil mirror of the Copeland compressor. When the internal and external pressures are relatively average, the refrigerant can no longer be added at this time. Now you can start the compressor and continue to add Note. When filling refrigerant with Emerson Copeland compressors, we must observe the current of the clamp meter while filling. When we fill the refrigerant and see that the number on the clamp meter is close to the rated current value, we have to stop filling the refrigerant at this time. At this time, we first let the Emerson Copeland compressor refrigeration system run for a period of time, and then observe the current value. If the number is low, then raise again, we have to observe it several times, and finally the value is stable.
