Hey all, I live in The Netherlands, so no surprise, solving the cooling in a barn for a small cluster i intend to solve by blowing some air to outside.
Now the small cluster will be a few kilowatt only, so i wonder how much air i need to blow in and out of the room to outside. As this is a cluster for my chessprogram and it maybe 1 day a year reaches 30C outside, we don't have to worry about outside temperature too much, as i can switch off the cluster when necessary that single lucky day a year. If it's uptime 99% of the time this cluster i'm more than happy. Majority of the year it's underneath 18C. Maybe a day or 60 a year it might be above 18C and maybe 7 days it is above 25C outside. I wouldn't have the cash to buy a real airconditioning for the cluster anyway, as that would increase power usage too much, so intend to solve it Dutch style. Interesting is to have a function or table that plots outside temperature and number of kilowatts used, starting with 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5 ,5, 5.5 , 6 kilowatts. For sure cluster won't be above 6 kilowatt. First few weeks 1 kilowatt then it will be 2 kilowatt and i doubt it'll reach 4 kilowatt. Which CFM do i need to have to blow outside hot air and suck inside cold air, to get to what i want? Thanks in advance anyone answerring the question.
