    It seems their product already proves the strategy I'm going for. However, it seems like their approach would be better if they offered an "ice battery" that could be stored inside the cooled space. The units they show on their site both have the ice battery incorporated into the outside unit, which has a huge footprint. It is insulated, but it will still absorb plenty of BTU's through the insulation. However, if the ice battery was stored inside the cooled space, any BTU's that leak through the insulation would just provide ultra-cheap cooling to the cooled space.

    Progress is slower now, but I am nearly done installing the blower. The air-to-water heat exchanger is scheduled for delivery on Friday, but I still haven't decided whether to install it just before the blower in the large chanber, or install it after the blower in the small chamber. The documentation for my blower indicates that coils should be installed before the blower ("up stream"), but the coils in my central AC units are installed after the blowers. Is there any reason why it would matter?

    I decided to put the air to water heat exchanger after the blower. I think I'm just a few hours away from hooking up the water pump, but won't be able to work on it again until Monday. However, I did get the blower hooked up with 5 different speeds, which are selectable via dry-contact relays. I've also verified that I can use those speeds to vary delta T between the inlet and outlet. I haven't jacked with it much, but I achieved just over 30 degree F drop with a medium air flow.

    Actually, it is working, but I haven't totally decided how to best utilize the cold water. I'm just working through each theory, so I can scratch them off the list. In the meantime, I have achieved a significantly lower RH, and have reduced my average cooling cost by at least another 25% with even greater comfort.
