Yes I would concede that is it in a nutshell where we disagree and I may have been abrasive as you walked in the end of a long thread and where at first I doubted your ability to tie your own shoelaces(not bashing it is my general first assumption about everyone) I also concede that certainly is not the case and even though we differ on our opinions of a certain application I will say I respect the experience that arrived at it which is 10 years more than mine but again South Florida is a unique climate the southern most point in the U.S. so I feel my experience "in my backyard" is good and I understand your concern about the icing up of the system and in any other location of the U.S. would agree with you(except maybe Hawaii). The load calc without a crisatl ball I cannot really tell as the variables that have not been given are too many but I do disagree with your 5 ton assessment but understand why you arrived at it. Again also if I did agree with the 5 ton assessment(I do not) for this type of application would never reccommend installing a 5t system but 2-2.5 tons.
I think besides my words in time if server reports back how the system works we will find which school of thought was correct. And you have kept me on my toes making think of why I know the things I know which is always good for my learning process or helps me get rid of faulty thinking when I have always done something a certain way maybe because I was taught it or whatever but then when examined I have actually no technical basis for why I do it. However,that I did not find to be the case here so:
First I conclude that the Trane 3 ton system and the contractor selected by serverroomcooling meet with your approval. And two, I conclude no condensing capacity control will be required on this 3 ton split system.
The above as you stated is my professional stance on this and I am sticking to it. Again #2 only because of the geographical location. Otherwise I would agree with that
I think I explained my reasoning on the 3 ton which I know you disagree with which is ok with me.
I believe I will be right in this case but that does not really matter the purpose of this thread was to offer advice to serverroom and I think he got more than he ever bargained for...lol. Ultimately it was his decision and he made an educated choice, he asked for advice here, got a 3 estimates I think, the contractor he chose did a load calc and is not some fly by night but already does work in his building.
That was the purpose of this thread till it was hijacked by me to get in a peeing contest about what I know cause that is where I was born so to speak in the Hvac trade and so I am passionate about my backyard but I am willing to eat crow and Kowtow if serverroom comes back and updates us with a horror story.
