13. Installation and Servicing Air Conditioner using R32 13.1 About R32 Refrigerant For air conditioning refrigerants such as R410A, the refrigerants were collected back in order to prevent their air dissipation, to curbe the global warming impact, in case they were released into the atmosphere. In the “4th Environmental Basic Plan”, 80% reduction of greenhouse gas emissions by 2050 is required, and due to this requirement, further reduction in the emission of high greenhouse effect gas, such as CFCs, is required.
Page 44
2. Characteristic of Pressure As shown in Table 2, R32 does not have much difference in vapor pressure at the same refrigerant temperature comparing to R410A, but comparing to R22, it is higher at 1.6 times more. Thus, the same as in case of R410A, it is necessary to do installation and service using high-pressure tools and components.
13.3 Refrigerant piping installation • Tools used in services 13.3.1 Required Tools R32 refrigerant air conditioners use the common parts as R410A air conditioners for two-way valves and three-way valves (diameters of service ports); thus, they maintain commonality in the maintenance of the compressive strength, the size of pipe flaring, and the size of flare nuts as R410A.
Page 46
3. Torque wrenches (diameters 1/2, 5/8) Manifold gauges / Charging hoses In order to strengthen the compressive strength, the diameters of wrenches change depending on the flare nut sizes.

13.6.2 Process of refrigerant recovery 1. Connect the center charging hose of manifold gauge to the in-let side of recovery device. 2. Connect the valves of the discharge side of recovery device and liquid side of refrigerant cylinder with red hose (charging hose).
Page 53
13.6.3 Relocation 1. Removing the air conditioning unit a) Recovery of outdoor unit refrigerant by pumping down Press “forced cooling button” (as a general rule, since 1998 the name of cooling testing button is changed, and this name is unified within the air conditioning industry), and then you are able to start cooling operation in which the room temperature is low, and you can recover the refrigerant from the outdoor unit.
Page 54
13.6.6 Re-insertion of refrigerant in service When re-insertion is needed, follow the procedures to ensure the insertion of new refrigerant at correct amount. 1. Attach charging hose (blue) to the service port of the outdoor unit. 2. Attach charging hose (red) to the vacuum pump. Fully open the 2-way and 3-way valves. 3.
13.7 Repairing of refrigerant cycle / Brazing point 13.7.1 Preparation for repairing of refrigerant cycle / brazing Brazing which is a technique needed for repairing refrigerant cycle requires advanced technique and experience, and this brazing procedure can only be performed by the workers who completed “Gas Welding Skill Training” regulated by the Occupational Safety and Health Act, and went through the training programs of refrigerant operations.
