10 Installation And Servicing Ai r Conditioner Using R410A 10.1. OUTLINE 10.1.1. About R410A Refriger ant 1. Conver ting air conditio ners to R410A Since it was declare d in1974 that chlorofluoroca rb.
d. R410A refriger ating machin e oil Conven tionally , minera l oil or a synthet ic oil such as alkylbe nzene has been used for R22 refriger ating machin e oil.
10.2.2. R410A Tools 1. Cooper tube gauge for clearan ce adjustment (used when flaring with the conven tional flaring tool (clutch type)) • This gauge makes it easy t o set the clearan ce for the copper tube to 1.0-1.5 m m from the clamp bar of the flaring tool.
5. Chargin g hose • The pressu re resistan ce of the charging hose has been raised to match the higher pressu re of R410A . The hose materia l has also been change d to suit HFC use, and the size of the fitting has been change d to match the manifo ld ports.
8. Electro nic scale for refrigerant charging • Because of the high pressu re and fast vaporiz ing speed of R410A , the refriger ant cannot be held in a liquid phase inside the chargin g cylinde r w.
10.3. REFRIGERANT PIPING WORK When working with refrigerant piping, the followin g points must be careful ly observ ed: no moisture od dust must be allowed to enter the piping, and there must be no refrigerant leaks. 1. Proced ure and precau tions for flaring work a.
2. Proced ure and precau tions for flare connec tion Table 11 R410A flaring dimensions Nominal diameter Outside diameter (mm) Wa ll thickness (mm) A (mm) R410A flaring tool, clutch type Conventional flaring tool Clutch type Wing-nu t type 1/4 6.35 0.8 0 - 0.
Precau tions • Be sure to read the instructions for the vacuum pump, vacuum pump adapto r and manifo ld gauge prior to use, and follow the instruct ions careful ly. • Make sure that the vacuum pump is filled with oil up to the designa ted line on the oil gauge.
10.4.2. Transfe rring (Using N ew Refriger ant Piping) 1. Removing the unit a. Collect ing the refriger ant into the outdoo r unit by pumpin g down The refrigerant can be collecte d into the outdoo r unit (pumpi ng down) by pressin g the TEST RUN button, even when the temperature of the room is low.
5. Set the refrigerant cylinde r onto the electro nic scale, then correct the hose the cylinde r and to the connec tion port for the electronic scale. (1)(2) Precau tion: Be sure to set up the cylinde r fo r liquid chargin g.
10.4.6. Brazing As brazing require s sophist icated techniq ues and experie nces, it must be perform ed by a qualifie d person . In order to prevent the oxide film from occurri ng in the pipe interior during brazing, it is effectiv e to procee d with brazing while letting dry nitrogen gas (N2) flow.
