Been talking nothing but steam lately and I sure am steamed up about the insane refrigerant regulations. So I'm back propounding flammable refrigerants that work on small fixed charges at pressures as much as an order of magnitude less than the junk they're pushing on us and are non-patentable naturally occurring compounds. And otherwise want to talk about whatever you want to talk about instead of grinding my axe.

of course if this light snow for the northeast on sunday turns into another barn burner, I won't get out of dodge but otherwise i'm looking forward to seein' everyone.

    Thanks for doing this. I wish I could make it to AHR this year but I can't. I hope you keep planning things like this it's a really nice thing to do, and maybe I can make it to one someday

    @Mad Dog_2 that rugby match ain't got nothing on me playing the skunk at the garden party at the refrigerant seminars at AHR. ;- )

    @GGross i'm glad to do it. it is a little like being on the wall in person. different folks every year. sometimes 2 sometimes 10.

    Not sure where you are locatred but did notice there is the "installer show" for NY/NE HVACR in march (18, 19) as a side light to New York Build at the Javitts center in NYC that looks like a regional version of AHR and given that the NE is the region for some of us wallies might be another chance for breakfast. thats a couple hours from me. from what i can see of the context the HVACR component is downline of some UK expo. it sounds like they plan to do it annually in NY, which makes it an easy regional shot for me. and if i feel like its just a repeat of everything i saw at AHR i can go in the build expo. i'll get a pass for both.

    had coffee without caleffi today for the first time in a few daze cause i'm home, but look what @hot_rod cooked up besides the cappucino. convert from multiple pumps to multiple zone valves:

    albeit coolest find of the show because of my interest in flammable refrigerants was spacepak R290 5 ton chiller style heat pump. still waiting to get the COP curves but 167deg F out. once they get me a cut sheet and availabilities i'll post.

    they recommend 35% 1,2 propanediol (PG) for burst vs freeze protection since you are going to be in heat mode enough to keep it from slushing anyway unless something goes wrong in which case you want to protect against burst because of the portion of the hydronic circuit that is outside (although 1,3 propanediol (PDO) has lower viscosity. a little harder to find a direct specific heat comparison although AI says the thermal properities of PDO are superious. it's more expensive albeit less toxic. I wish I had spent more time at a few chemistry booths although we got installer show at javitts and eastern energy at mohegan sun coming up. don't know how many chemists will be at those.

    I'm really impressed although i'll be even more impressed when they start using the lowest pressure isomers like isopentane because I think with the lower pressures you could even more easily make service compenents with isolation and modular unions that wouldn't be subject to leaks in the comparatively lower operating pressures. but guy at booth (damnation thought i got his card) said they didn't want to be too exotic seeming and propane has bigger installed base at the moment. true isopentane is more expensive but we're talking $400 for a metric ton of propane, $1300 for a metric ton of isopentane and $55,000 for a metric ton of R32- just sayin'.
