ok went to the job tonight (last call) walk in cooler (beer)
its the first time i ever been to this job
it has 2 mismatched evaps, a 2 fan evap with a 1 h/p cond. and a 3 fan evap with a 2 h/p cond.
2 different stats for the same cooler
cooler is 25 wide x 8 length x 7 foot ceiling,
anyway the 2 hp comp. has wasted valves and its old, i am gonna replace the condenser
i am probably gonna wire a relay to turn both compressors on and off at the same time thru 1 controller
maybe i will slap a 1 minute delay between both stages for $hits and giggles
or is there a different way anyone else would do it?
my second thought was turning one stat (the bigger condenser) a few degrees lower than the other
what option would you guys use, and can you see any advantages or disadvantages one way or the other
