    High pressure condensate temperature

    Hello All: This conversation gets better and better!! :-) And I thought it was "wrapped"! As someone in this thread said: "All things are relative." About all I can say to the last message is: RIGHT ON!!! Perhaps this too: "The existence of a code does not a safe...

    water wetter

    EUREKA, GUYS!!!... I FOUND IT!! Not "water wetter"; but basically the same thing at the supply house (Farm and Barn) that I asked at last night. This time I looked on the "snake oil" shelves... since snake oil is cheaper than a new engine or tranny and I travel around the...

    High pressure condensate temperature

    Quark: Thanks for wrapping up this nice little discussion. I really learned a lot. Thanks to everyone else who kicked in their 10 cents. The only dumb ? are one not ?? Even though "i've worked with steam" for awhile, it appears I always have something to learn; which makes life not...

    High pressure condensate temperature

    TBP: Thanks much, TBP. The web and info highwayis truly a wonderful place! Now I just need a good antivirus package. :-0 Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful observation/analysis; and it agrees with reason, is conducive to the common good: accept it...

    Quark: Tanks a bunch! :-) Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful observation/analysis; and it agrees with reason, is conducive to the common good: accept it and live up to it."

    water wetter

    Islander: Are Auto Zones a National chain? Never heard of them in WI, MN or IA. Or has life been passing me by? :-( Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful observation/analysis; and it agrees with reason, is conducive to the common good: accept it and...

    water wetter

    Quark: They never heard of "water wetter" at the supply place I went to last night. Do you think JC Whitney in Chicago would have? See The post on page 2 about keeping an AHU from freezing. Guess my theory of increasing the specific heat by adding something is "all wet&quot...

    High pressure condensate temperature

    TBP: Well said!! I read of a service man who was knocked unconscious in a valve pit and then literall cooked to death by "low pressure" steam at 15 psig. :-( No pun intended, but at a saturation temp of 212F the poor guy was "well done" when they found him. (Yuck :-( ) In...

    water wetter

    Islander: I'm going to check it out. Sounds like it might be good for the entire drive train; especially with summer coming (Here in the Northern Hemisphere, anyway!) :-) Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful observation/analysis; and it agrees with...

    I need inforamtion on a useful heat pump

    Dan: Got to Trane.com and seach first for "Absorption Chillers" and then "Heat Pumps". They have all types of both: single stage, two stage and DFA AAbsorption as well as closed and open loop heat pumps. All sorts of sales, applications, case studies, service and...

    water wetter

    Islander: What is the "stuff" you put in your radiator system? Sounds like it either cleaned fouled tubes or increased the solution's specific heat.... maybe both? Sure hope it wasn't sulphuric! :-) Actually, now that I think of it, it is very common to use Octyl Alcohol in...

    High pressure condensate temperature

    Beginner: Remember saturation temps, subcooling and superheat? Look at a steam table to find the "saturation temp" associated with the fluid (water) pressure. Then if the actual water temperature is above the sat'd temp (for that P) you have "superheated" condensate: [Tsh =...

    Backpressure on domestic heating/cooling systems

    Howdy All: When we're working for someone else, we're required to "do it right"; but in a pinch on my own home system, I usually opt for the baling twine and scotch tape! :-)... Thatis until I sell the home. Since I live out of the city limits, I'm usually not subject to code...

    Which software better

    Small Diesel Heater with Adj Temp

    Buzz: Nice to see you "play it safe". When at Trane, we use decade boxes all the time as service tools to "fool the RTD"; afterall: RTDs are just "dumb resistors" As long as you have safety overrides (which it sounds like you do) I would think you're O.K.. But to...

    Insulation of Supply duct

    Vicsidu: be sure to check your applicable, most current codes: Using ceiling plenum for RA is O.K. if the material up there is non-combustible. Otherwise :-( Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful observation/analysis; and it agrees with reason, is...

    Which software better

    For ease of use at an exceptional price, with exceptionally accurate results, Check out HVACCalc.com. They have both residential and commercial versions. I use the Commercial version. Tell Don I sent you and maybe I'll get some "free gifts" or at least an "atta boy"!! Or...

    Dual Duct System

    Right on: You are experiencing "stratification" ; which is why a certain number (4?) of duct diameters before any branching is recommended. If you have the space, I'd extend the ductwork. :-) Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful...

    ChasBean and Ken: Fantastic answers! Ones for my technical Scrap book. Paul/Goorah Buddha's advice 2,500 yrs ago (I'm Christian!!???!!): "After deep, careful observation/analysis; and it agrees with reason, is conducive to the common good: accept it and live up to it."

    PTACs

    Clayto: That's a whole lotta air!! Checkout Trane.com and look up PTAC. They claim 65cfm to 70cfm OA "off the shelf"; which is only about 18% for a one ton... perhaps the range you need for a 0.5 ton? What size are you considering? If it's very large, then you might want to consider...
