But you must be really good at it. To do it on a napkin.
I'm in no way bashing your product. All I'm saying is that we use our Canadian Books in Canada.. I have no experience in the USA. So when I join these threads all I can talk about is what I know.
We have two different books, Residential and Small Commercial, a lot of guys try to use Residential calcs on Small commercial buildings.. Not that you guys care.
Sometimes I wish HVAC Talk had a...
That is really good, good job jtrammel.
Is this directed at me?
If so we have a different book that we go to for residential air system design.
My spread sheet does the math for you so there is no crunching number, all you do is put each input into the box and then it spits out an outcome, all it does is saves you from doing the same math...
[QUOTE=CircusEnvy;21521421]Thanks a lot for the responses. What really impressed me about the software is that it'll map out your duct work and size it appropriately too, I thought that was cool. But...

Also, since we have long cold dry winters, we also use a scale on the outdoor design temp to what relative humidity your house should be maintained at. Adding humidity by means of a duct mounted...
Hey rider77 where are you from, where I am at it gets to -46f, load calcs are based on the outdoor design temperature for your city town and the indoor temperature you wish to keep it at., unlike the...
In canada, HRAI certifies technicians after completing a course given by them. In this case, the technician would have his Residential heat loss heat gain certificate and can use HRAI'S LOAD...
Where in Canada are you located? Are they HRAI certified and did they do a Heat Loss calculation, obviously not considering one company bid you at 40,000 Btu.. And those numbers are the input not the...

What did your final TESP end up being? The Tee that you made looks nice, depending on your R/A velocity you may have some turbulence when the two air-streams meat head on. Have you tried fabricating...
12 installs in a 5 day work week with 64 man hours a day and 320 man hours a week, 2 man install should only take 16 man hours, you guys should be pumping out 20 installs a week.

Just tell them not to buy good filters. Get the crappy ones, they have very little restriction and they take out the big stuff. In a few years, clean the blower and coil. Good as new.
Or when you...
1 Cubic Foot of Nitrogen Gas at 70°F and at Atmospheric Pressure weighs 0.072 lbs, So a 39 ft3 cylinder would have a Nitrogen weight of 39 x .072 = 2.808 lbs, I think.. haha, we are getting close to...

The pump should only energize when the machine is in ICE mode. I dont know for this one if it is thermally controlled or time on.
It says blocked spray nozzle or short on water. Also check for proper distribution of water. How many harvest cycles did you pass through after changing the filter? I usually rinse my filters in...
If the ice cubes are cloudy, an extreme water condition may exist. Confirm that they are cloudy byplacing them in a glass of cold water. If, in the water, they remain cloudy, you may want to have...
You never know, maybe you are in a negative pressure. Is he the landlord asking for a air balancing report from the company to legally bind you to the lease agreement? Can you ask him if you can have...
Nice, what did your TESP end up being?
If you are talking commercial,
The Kitchen will be in a negative pressure and the dining room will be in a neutral to positive pressure.
