I am trying to get an idea for the efficiency of the unit, and how much more efficient would the system be if I were able to cool the pressurized coolent further. I am considering a heat exchanger with cool water from a river, or well, to suppliment the normal air exchange.
(You can only subcool so far without returning to saturation point...uh....I think that's right.Pleas correct me if I am thinking wrongly.)
So, on a hot day, use the blower to cool it down to the 90 degree temp outside, and then go through the water cooler to see if you can run it down to below 70. How much more efficient would that make the system?
(You are on the right track in you thinking...however I dont know if this is really practical.The genuises at goodmans figured it all up and I just believe 'um)
Would my compressor run at a lower pressure? Or just kick on less frequently?
(Yes I think you would run at lower pressure because more of condenser space would be available for desuperheat and condensing,but I am no expert.I think you have to get your liquid pressure back up,for several reasons.Where the hell is R.J.Dalton?
The more I think about it, the less I know.I hope to see an simple,concise answer.)
Am I correct to assume that the units with a higher SEER efficiency rating run under a higher pressure? And therefore have a higher temp difference across the system?
