  • PROOF OF CONCEPT: A chilled water air conditioning prototype.

    Yes very clever. I would be interested in knowing the temp difference between the water supply and return. The temps you have listed are of the heat exchanger and the compressor unit. That difference won't give a measure of cooling efficiency. Measure the water temp before and after the heat exchanger. The delta of the water temp should allow a standard for measuring efficiency of design changes. The bigger the difference that can be continually sustained the better.
