    new home ,air changes per hr?

    Silfox's link had an extra "dot" after "org". Try this one... www.rebuild.org/attachments/guidebooks/ventilation.pdf Looks like you need to be a "partner" to get full access the site.

    Variable Speed Primary Loop

    PacificSteve is right on the money. Ice storage takes up much less room than water storage, but without incentives or a decent rate structure, it's a real tough sell. Something to keep in mind: to keep from running glycol throughout the chilled water distribution and worrying about leaks and...

    Variable Speed Primary Loop

    Thanks for all the input! The reason we are considering either the variable volume primary or a half-size chiller is to better match the secondary flow. Right now, due to the piping configuration (two separate secondary taps), the "most critical" of the two loops gets mixed (supply...

    Variable Speed Primary Loop

    Thanks, PacificSteve. The alternative design for the plant is adding a 400 ton chiller to allow for a "half-step". This may be the easiest method of making the plant match the load. Whaddya think? KentRo

    Variable Speed Primary Loop

    Howdy, We've got an opportunity to affect the re-design of a chilled water plant. Currently the plant has five 900-ton chillers, each with its own constant volume CHW pump. The plant has had to run an "extra" chiller to ensure both secondary loops get "all" chilled water...
