Ray Frechette Jr Posted July 20, 2013 Report Share Posted July 20, 2013 To any of our Canadian members. Thank you so much for sending the Canadian High pressure front down to Maine. Past week has been highs in the 90's with high humidity and Dew Points in the upper 70's. Over past hour the air has noticeably dried out and the temp has dropped 8 degrees already.!! Geesh, it was feeling like North Carolina here all week! Blech. Quote Link to comment Share on other sites More sharing options...

Dnjost Posted July 21, 2013 Report Share Posted July 21, 2013 Keep it coming!!! tired of building in this stuff. Pretty sure the mistakes i am making are due in part to the weather. Air mass just starting to change. Quote Link to comment Share on other sites More sharing options...

Peter HK Posted July 21, 2013 Report Share Posted July 21, 2013 I don't know how those in the south deal with this all summer Well Ray, speaking from very far south (Brisbane, Australia) where the climate is subtropical, about the same as Florida, I now have an air-conditioned workshop Luxury!

I don't know how those in the south deal with this all summer.... Welcome to Florida Ray . . . I too have an A/C'd shop, as do many in the subtropics. The shop, even un-A/D'd, isn't nearly as bad as working in the field, chasing snakes, with bugs big enough to carry you off to their lair and consume you in their leisure and the only relief being, the shadow of the bilge hovering over you, as you toil away. I've actually scheduled work, so I can stay on the shady side of a project during the day. I feel sorry for roofers. Quote Link to comment Share on other sites More sharing options...
Ray Frechette Jr Posted July 22, 2013 Author Report Share Posted July 22, 2013 No AC in shop here. Can't ever see installing it either. Weeks like this past one is fairly rare. Yeah we get weather like that for 2-3 days, but 7 is rare. I gotta wonder on AC'd shops, How on earth do you handle all the dust drawn into the heat exchanger?

Ray Frechette Jr Posted July 22, 2013 Author Report Share Posted July 22, 2013 Yeah but lost of fine dust gets past filters... I have a fan forced hot water heater mounted to ceiling to heat shop in winter. It gets a fair amount of dust in the crevices. I plan on hosing it out next spring again....

PAR Posted July 23, 2013 Report Share Posted July 23, 2013 Cleaning out the air handler is not hard or unusual. Growing tied of this the cold air return plenum was reversed, so it draws air from the "clean room" portion of the shop and now has a prefilter to catch most of the dust, before the main filter gets it. They sell much better systems, some hydrostatic that energize the particulates, which then get attracted to a series of plates. The simple solution is a soft brush on the end of the shop vac, over the evaporator coils every so often. Though my unit does have a 60kw heater, it's very rare to need it down here. I think I did once last winter. Quote Link to comment Share on other sites More sharing options...

That should work at the North Pole too... Do you have 500A service to your shop? ;^) Quote Link to comment Share on other sites More sharing options...
PAR Posted July 31, 2013 Report Share Posted July 31, 2013 This is what we call strip heat here in the Sun Shine State and a pretty common setup. Depending on how much sq. footage and insulative value, you'll install heating elements in the plenum of the air handler, typically in 20kw units. This unit has two 30's on a four ton can. It's not something you want to use much, as it's like a giant toaster and eat electrons like you can't imagine, so I have this installed on a two stage system, which basically uses the strips to offset the heat pump when the ambient air temperature is in the 40's (30's a rare). The heat pump can maintain the temperature once you're there, but needs help if it's cold outside, at least until the internal air mass is warmed a bit. I had a reversing valve take a dump on me a few years ago (this unit) and she ran on the strips all January and February, in the coldest year we've hard in decades. My electric bill jumped $500 each month and I liked to crap myself, but it's how I knew something wasn't right. Quote Link to comment Share on other sites More sharing options...
