Amazing breakdown on the cloths dryer, Looking forward to seeing part two. I Very much want to start building one of these. Just have to figure out how and where to put the immersion infrastructure for the miners heat exchanger and radiators
Bob! this is exactly what I'm trying to do as well. I'm figuring for more commercial. have you thought of down/under clocking the miner as well to reduce the air flow and temp? you could have one exhaust to outside and one piped into the dryer. I've also thought of using a timer at the wall that both the dryer and miner are plugged into so they power on at the same time and run as long as the dryer is set then they both turn off. this would need another mm board or something similar. Your idea with immersion is awesome too, I'm thinking air cooled. but then, i have the issue of noise (somewhat) and excess air that's not going into the dryer. Working it this way, I'd pull out the heating element and keep the tumble feature. I'd also like it to be coin-op. Such an awesome idea and way to make older miners profitable again. Imagine even charging customers 50-75 cents per hour .... that makes most miners 3-4x more profitable. aaaand it saves the customers a lot of money being that most charge 1.50 + per hour. Immersion I think would be a lot cleaner a look and cooler temps, way less noise. Like you said, it's just the airflow. maybe once it reaches a certain pressure/cfm the air would vent elsewhere or be sent to cool in a roundabout way. -a small laundromat with maybe 6 washers and 6 dryers is what I'm thinking of, I appreciate your work and the thought you put into your projects! it's all helped me alot at home
Funny...as I've been building, I've thought more and more about how this would/could scale up to a commercial site. If you ever want to collaborate, find me on Telegram and we can talk!
I'm sure you've checked the numbers. I just did a check on mine, out of curiosity. On high heat the dryer system draws 22-23A @ 240v. There is one higher setting, but we never use it. If you've tested, what kind of draw are you seeing with the heating elements "disabled".
Another concept I'm starting to look into is using our cold well water with an exchanger to cool the house before it goes to the irrigation system, which runs for an absurd amount of time each day in the summer (6-8hrs)
@@nickdaniels7593 Good question...so when my dryer is running normally, the current draw is always the same regardless of low/medium/high setting. The difference is duty cycle...at the low and medium settings, the heating element is turned on/off during the drying cycle. When I run the dryer in 'air dry mode', the heating element is off all the time. The difference is 25 amps when element on and 22 amps when element is off. The remaining 3 amps is used by the motor which spins the drum and spins the dryer fan. ...I learned a lot about how dryers work on this project, LOL.
@@nickdaniels7593 that is a fantastic idea! If you have 6-8 hours of water flow, you can run it through a BPHE to cool the miner. Depending on flow rates, you might also be able to use an indirect water heater 'backwards'. The miner constantly dumps its heat to the water heater, but then your irrigation setup cools it down periodically...you might be able to keep your miner running non-stop this way.
