@ February 6, 2008 1:05 PM in Larger pex tubing.

Thanks for the responses. Expansion is one concern, but we can deal with that. We plan on near boiler/chiller piping of copper. We are running a 2" loop around this house, which will be concealed, so not being perfectly straight is not a huge concern. One thing I'm concerned is the cost of the uponor fitting tool, WOW. I agree, if someone made 2" PAP, that would solve several issues, but.. How about temperature, this system is designed with MAX water temp of 150 deg f, should we be concerned with loss of o2 barrier? J

As far as I know(we replaced a T-18 last year), it is a 8 sq ft coil. So cfm=500(fpm)*8(face area)= 4000 cfm. btu/h=4000(cfm)*1.08*35(delta T)= 151,200 btu/h. This is how I figured our replacement, and no problems so far. J

Anyone using larger (1 1/2", 2") Pex in place of copper. I'm working on a couple of jobs that the cost difference in pex vs copper could influence the design to stay more hydronic. We are looking at Wirsbo tubing, any input? Thanks J

Temperature glide.

@ January 19, 2007 5:32 PM in 410A vs R22

a zeotropic (blended) refrigerant has a characteristic that refers to the range of temperatures at which components boil or condense at a given pressure. With a system using a zeotropic blend with a high temperature glide, the more volatile components will escape first if there is a leak while the system is off, this is fractionation. While the system is running the refrigerant stays blended, and a leak is less likely to result in fractionation. This complicates the charging process of a blended system.

units like these: http://www.multiaqua.com/ They have a decent line of ductless-looking fan coils, and with the chilled water, small zones are handled well. Can run pex-al-pex, insulated to each fancoil, great dehumidification. J
