CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 12 Installation and Servicing Air Conditioner Using R410A 12.1. Outline 12.1.1. About R410A Refrigerant 1. Converting air conditioners to R410A Since it was declared in1974 that chlorofluorocarbons (CFC), hydro chlorofluorocarbons (HCFC) and other substances pose a destructive danger to the ozone layer in the earth’s upper stratosphere (20 to 40 km above the earth), measures have been taken around the world to prevent this destruction.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE d. R410A refrigerating machine oil Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 12.2.2. R410A Tools 1. Copper tube gauge for clearance adjustment (used when flaring with the conventional flaring tool (clutch type)) • This gauge makes it easy to set the clearance for the copper tube to 1.0-1.5 mm from the clamp bar of the flaring tool. Fig. 1 Copper tube gauge for clearance adjustment 2.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 5. Charging hose • The pressure resistance of the charging hose has been raised to match the higher pressure of R410A. The hose material has also been changed to suit HFC use, and the size of the fitting has been changed to match the manifold ports. Fig. 4 Manifold gauge charging hose Pressure resistance Material Table 8 Difference between R410A and conventional charging hoses Conventional hoses R410A hoses Working pressure 3.4 MPa (35 kgf/cm 3) 5.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 8. Electronic scale for refrigerant charging • Because of the high pressure and fast vaporizing speed of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 12.3. Refrigerant Piping Work 12.3.1. Piping Materials It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries.

Types of piping and their storage The following is a general classification of the refrigerant pipe materials used for ACs. Because the gas pressure of R410A is approximately 1.6 times as high as that of R22, copper pipes with the thickness shown in Table 10, and with minimal impurities must be used.

CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 12.4.2. Transferring (Using New Refrigerant Piping) 1. Removing the unit a. Collecting the refrigerant into the outdoor unit by pumping down The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the temperature of the room is low. • Check to make sure that the valve stems of the 2-way valve and 3-way valve have been opened by turning them counterclockwise.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE vacuum pump. Wait for 1-2 minutes, then check to make sure that the needle of the Low pressure gauge has not returned. See Fig. 13 for the remaining steps of this procedure. 5. Set the refrigerant cylinder onto the electronic scale, then connect the hose the cylinder and to the connection port for the electronic scale. (1)(2) Precaution: Be sure to set up the cylinder for liquid charging.
CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE 12.4.6. Brazing As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry nitrogen gas (N2) flow. 1. Attach a reducing valve to the nitrogen gas cylinder. 2.
