Please explain your setup in more detail. First, why are you using the water cooled heat heat exchanger in the first place? Sounds like unneeded complexity vs a simple AC unit.
Got my 1 hp chiller today. I'm setting up one UC system which will end up being two in two rooms and some ice boxes once I get the CO2 going.
I'd like to run a common supply header (line) out of a chilled water res. and have each load temp controlled by having a solonoid valve open and close to supply chilled water only when needed based on a thermostat for each system or space that needs cooling,
I was thinking of having a constant flow pump running but I'd need some back pressure in the supply to make sure I get flow to each load. I guess that means a pressure reducer at the end of the line where it taps back to the return to the tank.
Any of you experienced personages ever build out something like this? What kind of pressure should I run on the supply side, like 15 psi or what?
THanks in advance.
I'm looking at that too but the setup costs for the thermocouples and controllers is a bit steep. A cheaper source for a thermostat with a submersible bulb would be good to have. That way I could wire them up in parallel and the chiller and pump would only need to run when a load calls for it.
Then again the one pump I found that meets the flow criteria for the chiller is only a 120 watt load and the chiller will only cycle on when the temp of the chilled water is too high. Definitely things to think over.
I was thinking of building a manifold system such as the one in the hydro innovation video but I've been told that the system using the cold box's on each hood cause a shit load of humidity. Now you're going to create heat by trying to dehumidify the room or buy they're 1000. dollar WATER COOLED dehumidifier, (DONT THINK SO).
I don't understand why the rumor that ice boxes cause lots of humidity keeps spreading around. The ice boxes are a closed system. They aren't evaporating water into the air at all. Any condensation you find on the coils is from the humidity that was already in the air in your room.
