Daikin indoor wall hung units
Just a quick question that has always picked my brain everytime i see a daikin indoor wall unit. What is the purpose of those enlarged bulbs that are on the expansion line at the indoor unit, just after the flare connection. On a vrv indoor they are on both the liquid and suction lines just next to the flare connections. Sorry don't have any pictures. Thanks

Re: Daikin indoor wall hung units
I've cut them off in the past, I seem to recall them having small strainers in.

Re: Daikin indoor wall hung units
I've only chopped one off and that was empty. I always thought they were mufflers. Maybe on a VRV they might have filters in them as the LEV would be inside.
Cheers,
Andy.Health and safety first..........unless I'm in a hurry.

Re: Daikin indoor wall hung units
i believe the part you are talking about is a filter drier, called a copper spun filter drier. Iv never seen inside one, but i have been told the are full of a whole lot of little ball looking things behind a fine sieve, not sure how true that is though as iv never seen it for myself.

You should never cut them out as they also act a muffler, if they are cut out they can cause a whistling noise.

Re: Daikin indoor wall hung units
The ones that are empty must just be to muffle the noise surely, just wish they were further down so can still cut the flares off and keep them! Have also seen a strainer in one cant remember if it was daikin or not.
