quick math:
7e6/4700 = 1489 gal/day per ton
= 62 gal per hour
= about 515 # per hour; or 515 BTU per hour per deg F
Say incoming aquifer water is 60F, out = 35F (to avoid freezing evaporator)
delta T = 25F, so 25*515 = 12875 btu/hr,
how about that, the math is consistent with the numbers, did not look right at first.
