: : It hotter than...well, anyway it is hot here (central Indiana).
: : I once had a store in a building that was cooled by water flow. Not the evaporater type they can use out west but it ran a trickle of water through a large cooling coil (a lot like an oversize auto-tranny cooling coil) which was mounted in front of a large squirrel cage blower. The water ran out a drain and it had a trough under the coil to catch the condensation which also ran into the drain.
: : It worked very well and cheaply. I have decided to build one for my shop.
: : --- Not today though, It's too dang hot. :-): I've thought of building something along this line using a couple of wrecking-yard automotive (truck, tractor?) radiators with a small pump to circulate the coolant. It would require fans on both the inside and outside radiator, and maybe an additional evaporative water spray on the outside radiator. I don't imagine the thermal transfer efficiency would be very high, but it might work well enough for a well-insulated building. I was originally thinking about this as an add on to an existing hot-water heating system in a house with waterpipes running through the concrete floor. I figured that running the system 24-hours a day would store plenty of cool in that slab floor to get through the day. : Now if your shop happens to be near your well, and you are pumping much irrigation water on hot days, you could set up a dandy cooler with several radiators in parallel (to handle the water volume flow). Ground water is usually plenty cool enough to provide some good cooling. Plus your crops would get warmer water, which is supposed to be good for them. : So, other than an umbrella (ha), what's your favorite way to stay cool on the tractor?
Diet cola. :-)
