Thanks for the reply! You are right about the axis being flipped, i was doing a lot charting will excel and didn't post the one i wanted to. But if you think about it the shape of the curve and relationship doesn't change when you flip the axis. You can take my curve above, rotate it 90...
I am not an Engineer but a contractor with lots of years experience. There is probably some math you can throw at it in terms of supply air temperature and jet velocity from your registers but bottom line is warm air rises. You are on the right track with downward facing registers with a high...
Hi All,
Haven't posted in a while but I ran into something I am not understanding. And deep down I probably know the answer is way more involved than simple math but I am curious to know your thoughts anyway. Here is the problem. I have an air delivery table from a manufacturer that gives...
Pretty slick they are multi position mount. I have not had any luck at all finding a distributer in the US for any Panasonic HVAC products. I sent out a couple of emails for info and haven't received any replies back yet. Still working on that side of things.
I am competing against (2) other contractors both quoted (2) 3-ton splits so a raised floor didn't enter into our conversation. It always nice to be the last contractor to bid something, save the best for last kinda thing
I am still waiting on the equipment audit from their IT department. They said they wanted (2) 3-tons, I said that might be a bit small so was bumping up to (2) 4-tons with a space for a 3rd in the future.
*typo.. they were thinking (2) 3-tons
The server cabinets will actually be open front and back and I was thinking distributing the air along the front of the cabinets. Thoughts?? This thread has been an excellent guide for me and I appreciate everyone's help.
Excellent point about cassettes directly overhead the server cabinets dBill. I was already rethinking things a bit. I was wanting 4 tons units and so far I see most high wall air handlers stop at 3 ton. This might give you some scale to my project, there will be a lay-in ceiling at around 10':
Pumping the cold air directly into the racks would be a nice optimization. I will have to talk to them about that option. I intend to do ceiling cassettes as they have better air distribution than the wall mounts, but that is me thinking from the perspective of human comfort. In my small pond...
Great stuff Alistair. I appreciate you pointing me to it; looks like exactly the setup for my project. Tomorrow I will search out my regional sales rep for these products and see where it goes. Thanks again and enjoy the rest or your day!
Nice Alistair,
I am doing primary with backup and they offer a unit rotation mode but still tied to a single controller, guess I can't get everything want. But really thanks, I am going to check into these.
225C is smoking hot. I can't imagine why any silicone in typical equipment would need to run much over 100. Of course all I can do is provide a target space temperature in the room and what happens inside the cases is up to someone else. For design purposes that target is 68 degF. In...
Thanks for the reply HVAC-Novice, I agree with everything you said and I plan on using commercial grade equipment. Very true modern IT equipment is very tolerant to temperature and humidity. It is the IT guys who think they need to run their room like a walk-in cooler.
Quick lil story...I...
