I live in a humid tropical latitude and electricity to cool my office/home runs about $675 monthly.
I have thought about setting up an Solar powered Ammonia Inversion System to make chiller water.
I kind of have the rough idea, along the 175' long roof peek I plan to put a solar parabolic mirrored half cylinder focused on a stainless anodized black pipe. The pipe will have a valve set to open at dusk. The pipe will be filled with pure liquid Ammonia. The gas pressure developed by heat during the day should vaporize all of the Ammonia into pressurized gas. When the valve opens the gas will run through a water tower dumping the heat into the air. after the water tower it will run into an orifice tube and large coil set submerged in a buried water tank. It should freeze the water into ice I then plan to use this as a heat dump for a series of chiller pumps running from wind power and circulating through the building. The expanded ammonia should return to liquid and be pumped back to the heater on the roof at night. In theory it should make enough ice to cool everything.
What I don't know is the formula and details of the old Ammonia systems used to make ice before freon R-12 r-22.
Can anyone suggest a book on the old ICE house systems ?
