ORC Setup in Garage - Advice Needed

AI Thread Summary
The discussion centers on setting up an Organic Rankine Cycle (ORC) system in a garage, utilizing two Swep heat exchangers and three used hot water heaters for heat input. The system employs R-134a as the working fluid, with a 1kW turbine and a 2 GPM pump for fluid circulation. The user is seeking advice on the appropriate amount of refrigerant to add, as they have a 30 lb. tank ready for use. Additionally, they have implemented various monitoring tools, including a mass flow meter and temperature and pressure gauges, to optimize performance. The setup is primarily analog, and the user is eager to share and learn from others' experiences with similar systems.

Hey I am new to this forum and I am looking for any pointers about my ORC before I start it up? I made an ORC in my garage with two Swep heat ex-changers, one B35 and one B10 (used but flushed). I have hooked up 3 (used) hot water heaters to the B35, 40 gal each with 4.4 kW elements in them, for my Q in. (A relative, who is an electrician, wired this system up for me.) I am using R-134a as the working fluid. I have a 1kW turbine and a 2 GPM (3/4 hp) pump for the working fluid side. For the heat sink or heat dump, B10, I hooked up a water fountain cooler to save on wasting water. I am about to ad freon and wanted to know if there are suggestions on how much I should ad in lbs? I have a 30 lb. tank. I also have a mass flow meter just before the pump for the refrigerant side and some temp and pressure gauges set up throughout the system. I am controlling the three pumps with three older but working VFDs for the pumps as well. This is mostly and analog set up. I am going to diesel mechanic school and my cousin who also goes there told me about this system. I had to make my own…thanks for any pointers! Oh and the system has been evacuated too. I am expecting to get 1 kW out of the turbine.

I have no idea, but I'd enjoy seeing some photos of this setup you have!
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
