CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 11 Installation And Servicing Air Conditioner Using R410A 11.1. Outline 11.1.1. 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...
CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 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-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 11.2.2. 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.
Page 47
CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 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.
Page 48
CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 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-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 11.3. Refrigerant Piping Work 11.3.1. 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.
CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE b. Copper pipes Use only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use.
CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 11.4.2. 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.
CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE 11.4.5. Recharging Refrigerant During Servicing When recharging is necessary, insert the specified amount of new refrigerant in accordance with the following procedure. 1. Connect the charging hose to the service port of the outdoor unit.
