Norm, you shouldn't post these questions here in an open forum. With the answers about evenly split, it kinda gives us "outsiders" the idea that half the hvac pros are wrong on any given issue... [/QUOTE
this is a good place because even if some us are wrong we learn and so do the home owners. just because we do this for a living doesnt mean we cant learn or realize we learned some thing wrong. at the same time the home owners that read this will also learn some thing of real importance for themselves. if they have a heat pump they need to now the answer also. we as pros come here to learn and expand. this way we can be better at what we do and can give the coustomers we have the best info and advise possible. we are not here just to solve other problems
right, wrong, or indiferant it is the learning curve that brings me here

That's funny.

We can agree that on a cold day a compression ratio of 7:1 would be not uncommon.And the same system on a warmer day might be more like 4:1.

7:1 ratio can be expressed as 7/1(7 divied by 1)or as 0.142
4:1 ratio can be expressed as 4/1(4 divied or1) as 0.25

So which is higher,4:1(0.25) or 7:1(0.124)?

.25 is higher

Sorry Jacob but any number divided by 1 is the same number.

7/1=7
4/1=4

1/7=0.14
1/4=0.25

The calculator never lies .

7. i believe quizes are learning tools where you eventually learn the answer from the person possing the question, that does not happen with these threads! To Bad.

I guess it's Norm's way of saying that if you don't know the answer, buy the book. But, what if we THINK we know the answer but are incorrect anyhow. So, buy the book regardless.

I do think that any question posted should have the author of the post reply with his answer. There might be some good exchanges that come out of it.
