so does this trump the ac in the door from last summer?
Basically, yeah. The door A/C has two limitations that made me re-think that approach. First, it didn't seem able to keep up with the heat load. Whether that's because the BTU rating wasn't beefy enough, or because on the OTHER side of that door is abnormally hot during hot weather (so the heat gradient it's trying to pump heat against is steeper than normal), it was not cooling the room enough. The second issue was air dispersal. The door A/C unit wasn't beefy enough in the fan department to move that cold air across the room, and it sort of cooled a segment of the room and thought it was "done" with its work. I could have fudged the settings, forcing it to run all the time, but this is very energy inefficient, and, in the end, I decided to pursue the most energy efficient means, which was to use the big house unit and air handling system.
I'm just sitting on the A/C unit for now, until it strikes me what do do with it. I suspect Junior Geek will be lobbying for it any day.
IN OTHER NEWS:
Remember this? Well, DK finally figured out the ball replacements. She ended up using color-coded easter eggs filled with glass bits for weight. She had both, and the fact that she was able to color-code them is boss.
What, you may be wondering, IS that thing?
Well, it belongs to Water Factory III. Water Factory III creates a number of unique water streams which are then blended at the tanks to make custom water for a tank. While the CIC-152 monitor gives a bird's eye view of system performance, it really only monitors one stream in the making.
It's critical that DK know if EACH stream is made correctly (i.e. that the injector for that stream is functioning within parameters). So what DK did was to create in WFIII a side/flush branch of each stream of the WF. This unit takes live output from its respective stream into a small (1 pint or so) chamber), a small proportion of the output from that cycle. We need to use a chamber, rather than just a point monitor, because the nature of injections is that they sine-wave over time, so you need an average of what the output is rather than a sample at one exact point in time, or you will not be accurate.
So, each cycle, a small proportion of each stream is diverted to these chambers for the duration of the cycle. They fill from the bottom and overflow out the side spouts, and collectively drain into the sump pit. But at any time, DK can pick up an egg, plunk in a TDS meter or draw a sample for testing, and it will reflect the latest cycle's functioning for that stream. This is critically important to be able to do, so that I don't have a malfunction happening blindly that I don't know about until it starts killing shrimp in the tanks.
For example, a month or so ago my check valve on one of the injectors developed crystals at the valve, causing a leaky valve, causing the injection solution not to be drawn up properly, so the stream was under-injected severely, depleting the tanks of that stream's contents. Fortunately, DK noticed some subtle changes in the shrimp coloring and tested her streams manually, finding the problem. At that time, she decided to fix her a better live system to draw samples, always. She has to have the side streams and "waste" a proportion of her streams, anyway, to get up to the flow volume she needs, for accurate injections, so she didn't waste anything by setting this system up.
The lids are very lightweight, and the tubings going into them tend to torque on the lids, causing them not to seat sealed and shut, without a good weight on them, thus the need for WEIGHTED plugs. The balls worked, but a certain half-feral wolf-wannabe kept coveting them, and they had to go.
It's an awesome system, now, and now it's very easy at any time to check a stream without having to turn on the system or divert a stream, etc. I just go to the respective pot and test away. It's basically automated and needs no maintenance, too. DK fantasizes about one day getting live monitors like the CIC-152 on EACH stream, but the individual monitors are still too pricey for her blood for this. And she can't be bothered with cheap battery operated "monitors" - for now she uses her hand held TDS unit and drop tests as needed.
