So i got a 2.8hp water cooled low bp condenser, but i got a water problem, right now the system will use about 4000 liters per day of 77c water, Not good, i gotta do somthing about that.
My plan is to hook up a 3/4hp condenser to a custom made spiral evp coil and stick it in a 300 liter plastic drum with some insulation, that also circulates to 2x more 300 liter drums giving a total res of 900 liters.. Im debating on using glycol or water, depending on how low i can get the temperature at. If i can cool the glycol down to like 20f, then it should offset the thermal transfer benefits of using water. But the plan is, i want to chill the gycol or water over night to temp, then use it thru out the day. I figured if i can get the temps down, for the water to around 55c or the gycol to 20c, then 900 liters should be more then enough to keep the condenser cooled, and i can always switch on the 3/4ths condenser if 900 liters of chilled water isnt enough.
So my question is, how low can the water temp be? do most water cooled condensers want a constant temperature of water? I figured the water regulator on the water cooled condenser will be able to adjust for colder water, but maybe they cant then i would imagine the head pressure would be constantly fluctuating with every opening on the water regulator.
if i am required to keep a constant temp on the water inlet, then i guess i have to scrap the res/over night chilling design and go with a a design that chills the water to temp as the water cooled condenser is running.
I have a few issues also, noise level has to be low, so i cant have a beefy air cooled water chiller, the 3/4ths hp condenser is at a good noise level for us.
