Hello,
I am trying to figure out what my cooling issue may be.
I have 2 issues.
1. The unit constantly cycles on and off with no load(Every 5 minutes). I have it set with 2 degree deadband and itt seems the temp raises couple degrees pretty quickly causing it to turn back on. The temp sensor that controls the compressors is at the bottom of evap barrel and had it down to 25, by the time it hits the supply header which goes though maybe 2 bends and 2 feet of pipe, my analog sensor is showing 30. I have a bypass valve at the end so I know it is circulating, but wondering if its restricted somewhere? I know if pumps dead head, the paddles will immediately heat up the glycol causing the unit to cycle.
2. False temp readings- My thermo wells in my tanks maybe stick in maybe less than 1/4". My rancos "struggle" to make "36 degrees f". I put those in quotes as we did our first canning run Tuesday and the more beer we drained, the colder my ranco showed. The canning machine showed 34 degrees at start, and 29.5 at the end. This issue maybe due to thermos not being long enough?
My glycol system has an submerged evaporator in a insulated drum. I am the 3rd owner so i assume it was custom built back in the day. psi on supply showing around 10 psi, return psi shows about 5psi. Running 1" insulated lines using first in, last out method. My solenoid valves are on supply side feeding bottom ports of tanks, with returning coming out the top.
So why constant cycle and why is the top of my tanks at the return side colder than what my ranco shows at supply side?
