Topic: Inverter - Air Conditioner - how to calculate (Read 5386 times)

It is cheaper to use "filtered fresh outside air" for cooling, than it is to use "air conditioning".

If you must use air-conditioning for a boost... then exhaust all the 200F air outside, and cool-down the incoming 90F outside air, before it gets to the GPUs.

If you just want to save all that head-ache... Invest in ASIC's, lots of them, which will easily out-preform any GPU. Investing in only a few is a waste. You are just swapping GPU's for mini-ASIC's, but still going to make the same money. If you invest big, you will get a realistic portion of the market before "everyone" has one, and squishes you out of the market.

Investments in ASIC's is the same thing... Invest now, you get 100% return in about a month, by the time it arrives to you. The next ones, if you re-invest that money in more of equal power, will take you two months to return... again, investing that in double now, will take you three months to get a return... then doubling will result in four months... etc.. until you finally stop investing, and have to "hope" you actually stay alive, with all the existing tired miners in your possession, to get your money back in a year... before you make money agan...

Since the major makers are making/manufacturing 100x more for themselves, before they sell you the "penny-miners". They are the only ones making money with ASICs in the future, not us. They already made our money from the pre-purchase (free loan that cost us 3x more than we gave), and will rape your "earned coins", when you realize you just can't purchase enough ASIC's from them, to take away the giant portion of the market they will consume. They will consume it, because every ONE they sell you, will result in at-least TWO they make, to neutralize the "percent" of the market you just took, by running one more, and to F-U, they make the other one, because they can, because the other manufactures of ASIC's are making them too.

Let them fight with the coins that will only be valuable to them in the future. Move directly to an alt-coin, and take you value with you. (EG, take the bitcoin value before they get a chance to take it from you. You have no chance in hell now... period. Because you are not MAKING the machines, that they are also running.)

GPU's, are already being squished out. Another two months, and we will be less than 50% of the market... another month after that, and we will be less than 20%, another month after that, there will be effectively zero GPU miners mining bitcoins. (We will have all moved to scrypt-based mining of the many alt-coins, Which ASIC's can not participate in mining.)

This is true. Law of conservation of energy. The energy that goes in has to be used/come out somehow... well almost true. I think a large percentage is radiated as heat, but some of it becomes light energy, noise, kinetic energy (moves a fan, vibration), etc.

All the energy used by a computer becomes heat. 

3.5KW computer = 3.5KW heater.  The first one just happens to be more expensive.

You need to know the "btu/hr" (also called "tons") capacity of the air conditioner  / inverter.
Then you can use the information provided by Photon to know how much heat load your air conditioner can handle.

3.5kW heat load when i will put heater with that power ?
So when i will put computers which have 80% efficiency, then i can put about 15kW power ?
So i can put about 60 x HD7970 in there ? to mantain temperature ?

Handy information:

1 watt = 3.41 BTU/hr

1 ton of cooling (12,000 BTU/hr) will handle about 3.5KW of heat load

Hi guys,
I cant find info about this

Now i have 6x 7970 Radeons and two powersupplies 800W - Corsair GS800 which has 82% Efficiency at full load.
Tell me is "Samsung Forte AQ12FKN" good enough for that ?
All hardware will be in a closed room 2 square meters. 3 meters high.

And also how much cards more can i put in this room with that samsung inverter ?
do you guys know ow to calculate this ?
