Was thinking about it, and I don't know what the cost would be, but I wonder if you could get hire a programmer to work with the whatsminer API and the temperature monitors you have in the room.

As the temp goes up it throttles down the miners, as the temp drops it throttles them back up.

Would probably require a lot of trial and error and obviously a PC or 2 in the room but it might actually generate more BTC. If it's a cooler day or as the ambient temperature drops at night the miners clock up a bit. But, during the heat of the day they slow down to keep the temperature manageable.

Whatsminers have environment/room temp sensor, located far from the hash board, on the upper part of the control board, and gives pretty accurate readings, those temps could be easily viewed with an API request, and then a command to reduce the power limit for the miner can be sent, shouldn't take much to have something like in place, I think AwesomeMiner already has a function to check the environment temp.

So it's either going to be an hour to two of coding my own script or reaching out to Patrick/AwesomeMiner to see if they have that in place, they usually implement most of the suggestions I give them (given that they make sense). so ya, long story short, that shouldn't be an issue.

Hmm, I'm a bit curious about this one since checking the manual on our farm (not mining, true farm oink oink) HVAC the rating in BTU stands on the amount of heat it can move from the inside to the outside.

So a perfect 1 000 BTU unit will be able to move out 1 000 BTU at 10C or 40C, but in your case if you produce 10,236 units of energy those have to be removed be it 10C or 40C outside, you need the exact same amount of heat to be taken out, what will change if the outside is 10C instead of 30C is the efficiency and consumption of the unit, again, this is if we talk about a sealed room that won't lose that much heat through the walls.

The efficiency of an AC shouldn't change based on outside temps, if does 1k BTU, it does 1K BTU regardless, now let's forget for a moment about mining, and let's just picture an empty room with little BTUs.

Now let's recall how an AC actually function.? the inside unit will suck room air in and passes it to the evaporator coil of the internal unit, so that it would come out colder, and that same "room air" finds its way to the evaporator coil (outside unit) where the compressor, refrigerant, and pressure do their magic to cool that same air.

The whole process can only do so much, most places I read say 10-12c below ambient air temp (remember the outside unit that does all that sits in ambient temp), so for the same room we are talking about, if the outside temp is 50c, and the goal is to keep room at 20c while feeding the ac 50c room temps is not going to happen, so this is where the BTU calcs come into play.

To bring a 4m*4m*4m room temp down to 20c where the ambient temp is 50c you are going to need a larger AC than to cool the same room to 20c where ambient temp is 30c, you will need the AC to do more BTUs per hour, this also explains why cooling isn't done instantly, as it's a gradual process, for the same example, when the AC first starts with room temp is 50c, the AC will suck in 50c air, bring it down to 40c, when the whole room is 40c, it starts sucking 40c air and it comes out 30c, all of that needs to be done fast enough before the room gains more outside heat.

So, BTUs are not related to ambient temps, but the overall cooling is.

So now, we can simply conclude that if the outside temp is 20c, and you want your room to be 20c, there is exactly zero BTUs that need to be removed, now what happens when you start producing heat inside the room?

Instead of using a miner as an example, let's use another AC turned on heating mode, so you have two ACs of the same size, one is hot to cold another is cold to hot, what would be the room temp when ambient temp 20c? since both do the same BTUs, they should cancel one another the room temp will still be at ambient temp, no?

If that's true (which I believe it is), what happens when you bring in another AC of the same size that is set on heating mode, so now you have 2 hot vs 1 cold? you end up with 1 hot AC since the cold ac will cancel one hot ac, correct?

How hot do you think that one lonely hot ac will bring the room temperature to? 10c above ambient temp? the room now is 30c, 20c? the room now is 40c.

Now replace that AC with a miner that does the same BTUs, which brings us back to my initial statement, if the ambient temp is 20c and you are okay with temps going to as high as 40c inside, you probably don't have to match the exact BTUs of the miners.

I could be wrong, but would like to know, how? Cheesy
