IONS WHEN SERVICING UNIT 11 1 Characteristics of New Refrigerant R410A 11 1 1 What is New Refrigerant R410A R410A is a new refrigerant that contains two types of pseudo non azeotropic refrigerant mixture Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant R22 11 1 2 Components mixing proportions HFC32 50 HFC125 50 11 1 3 Characteristics Less toxic more chemically stable refrigerant The composition of refrigerant R410A changes whether it is in a gaseous phase or liquid phase Thus when there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in composition of the remaining refrigerant Therefore do not add new refrigerant Instead recover the remaining refrigerant with the refrigerant recovery unit Then after evacuation totally recharge the specified amount of refrigerant with the new refrigerant at its normal mixed composition state in liquid phase e When refrigerant R410A is used the composition will differ depending on whether it is in gaseous or liquid phase and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in gaseous state Thus always charge the refrigerant while it is in liquid phase NC Ether type oil is used for compressor oil for R410A type units which is different from the mineral oil used for R22 Thus more attention to moisture p
