WOW That's Pretty Cool! Action Is Our Prayer
Action is our Prayer...
Hugh writes of the results: "I installed a 7500 btu unit on the right rear (south) window. The unit was given to us (Gwen and me) by our former neighbors across the street, and we're happy to donate it to SCUU. The unit appeared to cool immediately when I turned it on. The temp in the yurt was 90 at that time. As Jean notes, I've left it on, turned on high cool, coldest. Let's see what the morning brings. I'm pretty sure it will have some effect. Also note that this would be only one of two units that can be operated, the other one being the 6000 btu unit on loan from Spence and Nita--already installed on the left side of the yurt. In case anyone is wondering, I had to put the second unit on the right (south) side of the yurt because all the receptacles on the left side are on a single circuit, and the right are on a second circuit, 20 amps each. The AC units draw about 12 amps, precluding putting them both on the same circuit. The unit I install is pretty noisy, but it may be good to let it run from Sat. evening until the service, and then either put it on low fan or even turn it off totally. Someone can make that decision on Sunday morning. I would recommend that the first unit also be turned on on Sat. evening. I do like the idea of opening the skylight, even with the AC(s) running since it will allow some of the heat that collects in (due to the greenhouse effect of the skylight) the ceiling. Rather than bringing that head down with the fans and forcing the AC to cool that hotter air, letting it escape might be the best solution. It's not totally clear whether the ceiling fans blowing upward would help this or would just add to the mixing. It's an empirical question that we should pursue experimentally. We still have a couple of "summer" Sundays before September and cooler evenings return.
An added note, people have been concerned with cooling in the loft. My experience is that the control (remote) that operates that unit is not the most "user friendly." An additional problem is that the remote control does not communicate reliably with the AC unit. While one might be giving the proper commands to the unit, the unit may not be receiving them. Unless one hears the confirmatory "beep" from the unit, the command did not register. I visited the loft this afternoon when I was installing the AC unit in the yurt. The temp was set at 83 via the remote, and the temp on the thermometer read 83 degrees. It was about 90 outside, so the unit appeared to be working. I turned the temp down to 79 and cool air was coming from the unit, so it appears that the unit is in good working order.
You may recall some concerns raised over the main (central) AC in the house. I think it's already been reported but the problem with the cooling was that the unit was set to auto fan (correct), but the mode was set to off. The choices are heat, cool, and off. When I visited the house today, the temp was set at 75 and the house was quite cool. I turned the temp up to 78. We can decide what the temp should be if/when the house is not in use. I thought 75 was too cool (i.e., wasting energy) when no one was there. (We keep our home at 78-80 most of the time--a personal choice, not necessarily the preference of others).
Overall, we need to develop some "standard" practices and educate folks as to the way to use the systems.
Regards to all."
Thank you Hugh!
Thanks! & take care
