    I forgot how marvelous that ducting was. Presumably running it straight up and out the roof isn't possible

      It’s brilliant 😂 not straight up as the roof ridge is directly above it, but going out through the roof was my first suggestion to them.

    I know a little something something about air and the turbulence im feeling it from here. 😂 GL g that aint getting fixed.

      Turning vanes help turbulence to get you a more stable static pressure down the duct but its still shite. That cowling not being there in the first place is a joke, one of the first questions we got asked in mitsi course 😂

      😂 it’s fucked no matter which way to look at it. My last suggestion was to relocate the YKB and P Series units outside, turn the PUHY in the corner to face the wall with a similar set up to the other two and cut out that acoustics crap. Or remove the roof 😂

      Sorry mate, I don’t believe so currently. Are you based in Aus?

    Maybe some guide vanes in the duct bend would help.

    • @hvacraustralia

      It would help for sire. If my static reading was closer to 60Pa we could have suggested it, but I don’t think vanes would drop it that much unfortunately.

    I think you should have tried measuring the static pressure farther along the duct, closer to the outlet sound muffler. If the static pressure is higher farther along the duct, it would indicate that more airflow is coming out of the unit. Even though it wouldn't align with the manufacturer's requirements, I think increasing its maximum airflow would greatly help the unit.

      I did measure at multiple points the first time around without the cowl and there was a marginal difference in static measurements. From the reading I’ve done on this it does appear measuring either side of the fan within a meter or so is the correct spot. Regardless, I doubt any spot I measured would have given me a reading under 60Pa 😂

      I take me previous comment back, you’re right. I should have measured further down the duct for a more accurate average reading. Cheers.

    Given the static pressure increased, isn't that a sign that the airflow increased substantially? Still restricted by the outlet of the ductwork but it seemed like the cowl definitely helped

    • @hvacraustralia

      Yeah, 100% adding the cowl increased the airflow. My thought process for removing it after was that the units will decrease the frequency of the compressor to hit their target evap and condensing temps and have a lot of safety’s in place to protect the compressor. The fan motor doesn’t have those safety’s and if I left the cowl on with a static of 130Pa I didn’t know how long before the fan motor would be damaged pushing against that much of a restriction. The capacity of the units won’t be 100% because the unit won’t be able to ramp up the compressor but they shouldn’t lose another fan motor this way. This place isn’t quick on making decisions.
