    installing elbows in split ac connecting pipes



    hi
    i saw split unit ac
    but the connecting pipes between indoor and outdoor unit are strange
    the technicians add elbows to the pipes to decorating the exterior of the building
    the image will explain more

    as i know the elbow will decrease the pressure of the refrigerant then increase load on the compressor
    then decrease the refrigeration effect
    im right or not ????????

    The pipe is most likly coiled up because it was pre flared coils
    As for the elbows they are more than likely formed bends purely for neatness.
    How would you propose to do it without bending the pipe??
    providing the bends are done right and the diameter of the pipe is not significantly reduced the restrictions are minimal and so is the effect it has on performance.

    As long as the total equivalent pipe length is still within the manufacturer's design spec, it shouldn't affect the operation of the system.
    I can't tell for sure from the photos if the evap. is below the condenser. But if it is, perhaps the pig tail is there to act as an oil trap.

    Won't make any noticable difference, just think how many u bends there are in the condenser and evaporator to get five elbows in the interconnection pipe work into perspective.
    Mostly found in Oxfordshire, UK :)
