The HVAC/building enclosure intersection is concurrent to the above for me.

Last but not least, since delving deeper into this realm, I've met and continue to meet really great people whose passion for building science is captivating as well as motivational. Long live the building science community, and I also share a dream of renewable energy powered dwellings and buildings, reached by transportation fueled by renewables. Would be quite content with a net zero house and a BEV in my carport. Far more desirable than a McMansion and a V8 SUV.

A quiet unpolluted city with electric vehicles and buildings that supply all our energy needs is easier than getting to the moon but so far we keep hitting the fence. Yet, I cannot stop being committed to building science as a way of getting to a place we'd all prefer over what we have.

Being this system was new I went onto the roof with my trusty Fieldpiece dual probe in-duct psychrometer in hand and familiarized myself with the DOAS, which has a desiccant wheel to treat both incoming and exhaust air (performed by the same unit). Turned out the system was removing humidity like crazy, and delivering supply air to the locker room at a < 55°F dew point. So why was the locker room still so humid? I found a face/bypass damper set incorrectly, resulting in the locker room going negative to outdoors. The supply air fan was sucking on the building envelope to get enough air across the cooling coil, meaning humidity was mixing with supply air post-delivery. The damper actuator had been set incorrectly. Once that was corrected everything fell in line and life's been good since.

As for the condensing unit mister device you're about to write on, a thought occurred to me as I washed out my own home's condenser coils this past weekend. Often the argument is made by the mister fanboy crowd that if the water is filtered then it should not result in scaled up condenser coil fins. I then realized there's no way this can account for entrainment of dust and dirt into the mist as air is drawn into the condenser coils. After all, this is how condenser coils become dirty in the first place! So, it leads me to think that you could spray reverse osmosis treated water onto those coils, and they will still scale up over time as dirt and dust particulates are left behind on the fins as the water evaporates from the fins.
