3 replacement Special care should be taken for replacement. Refrigerant oil Previous refrigerant (R22) Mineral oil New refrigerant (R410A/R407C) Mineral oil cannot be used To protect the ozone layer, the conventional refrigerants (R22) have been replaced with the new refrigerants (R410A). However mineral oil is not suitable for the R410A refrigerant oil because R410A refrigerants do not contain chlorine. Without chlorine, refrigerants do not dissolve in mineral oil, which causes poor oil return to the compressor and insufficient lubrication. As a result, introduction of alternative high fluidity and miscible oil which is compatible with the R410A refrigerants is essential. When replacing an R22 with R410A air conditioner, proper care should be taken. The following substances remain in the existing piping Chlorides Mineral oil residues When replacing an R22 air conditioner with an R410A air conditioner, chlorine and mineral oil residues, which are not used in the R410A air conditioner, must be handled properly. Reusing the existing piping without pipe cleaning or replacement of pipes causes the deterioration of refrigerant oil and/or clogging of the refrigerant circuit, which lead to malfunction of the air conditioner. Reuse of the piping requires proper handling of residues. replacement Mitsubishi Electric s Cleaning-free Pipe Reuse Technology requires no cleaning. Need to Clean at the Time of System Renewal Chloride residue builds up in existing pipes and becomes a source of trouble. In addition, the iron particles and slime produced as a result of compressor failure lead to problems. To counter this, various original Mitsubishi Electric technologies have been combined to enable the introduction of cleaning-free pipe reuse. R22 refrigerant Why can t existing piping be used? R410A refrigerant Problem Problem Result At time of renewal At time of compressor failure Chloride residue Increased chloride residue Iron particles and slime High heat generated during operation Accelerated deterioration of refrigerant oil Refrigerant circuit malfunctions and causes failure Cleaning pipe or replacement with new pipe is required Mitsubishi Electric s Original Replacement Technologies Countermeasure for Problem 1 Countermeasure for Problem 2 Technology 1 Original High-quality Filtration Our original high-quality filtration device called the wide strainer is equipped inside the refrigerant inlet and outlet pipe. The wide strainer traps iron particles and realises cleaning-free pipe reuse. In addition, improvements to the metal used in the bearings of our new scroll compressors realise more robust units. Wide strainer Technology 2 Friction Reduction (moving parts in compressor) Friction inside the compressor is reduced by using an original Mitsubishi Electric technology called the Heat Caulking Fixing Method or coating the edge of the blade in the scroll compressor, thereby suppressing the increase in temperature that causes refrigerant oil deterioration. Existing piping can be used without cleaning Cautions when using existing piping When removing an old air conditioning unit, please make sure to perform the pump-down process and recover the refrigerant and refrigerant oil. Check to ensure that the piping diameter and thickness match Mitsubishi Electric specifications. Check to ensure that the flare is compatible with R410A. 3

18 Properties of R410A and R22 refrigerants Chemical properties R410A as well as R22 is a chemically stable, less toxic, and non-flammable refrigerant. Its specific gravity relative is greater than that of air. If the refrigerant (R410A) should leak in a closed room, it accumulates in the lower atmosphere to cause lack of oxygen resulting in an accident. The R410A refrigerant may also produce poisonous gas if it should come in direct contact with fire, so be sure to handle it in a well ventilated area to prevent accumulation of the leaking refrigerants. Composition change during liquid-phase charging (R410A) Concentration of HFC-32[W%] Container remains percentage (Remaining weight in the container/volume of the container)[kg/l] Composition change during liquid-phase charging (R410A) Concentration of HFC-32[W%] Container remains percentage (Remaining weight in the container/volume of the container)[kg/l] R410A is a near-azeotropic refrigerant blend of R32 and R125, so R410A can be handled in almost the same manner as a single-component refrigerant like R22. However, the composition between gas and liquid phases slightly changes in a container like a cylinder. Then, charge R410A in the liquid phase. Pressure properties The new R410A refrigerant has higher pressure than the previous R22 refrigerant. Temperature ( ) Pressure (gauge) R410A MPa(gauge)/kgf /cm²(gauge) R22 MPa(gauge)/kgf /cm²(gauge) / / / / / / / / / / / /26.5 As the vapour pressure of R410A is 1.6 times higher than that of R22 at a given temperature, perform installation or service with dedicated anti-high-pressure tools and materials for R410A.

Handling precautions Mixing of refrigerants R410A is a refrigerant blend of HFC32 and HFC125. R22 has different properties from R410A. Therefore, never mix R410A with R22. Pressure rise (R410A) As the vapour pressure of 410A is 1.6 times higher than that of R22 at a given temperature, use dedicated extension pipes for R410A. Tools dedicated for R410A may be also required. Special care should be taken in the installation or service related to R410A. Control of moisture If lots of moisture gets into the refrigerant system, it causes the capillary clogging and poor insulation of the compressor etc. Control of contaminants If lots of wastes, air, flux, and/or mineral oil get into the refrigerant system, it accelerates the resolution or deterioration of the refrigerant oil, which causes the capillary clogging and poor insulation of the compressor etc. 18
