Aftermarket cooled seats

[BroncoChicken]

I’ve been thinking about cooled seats, they really are a great feature. I’m thinking about going Big Bend and getting Katzkin leather and Degreez for heat/cooling. The Degreez add-on is apparently only $500 or so. Has anyone ever added cooling to seats?

I don't think you can, I believe it is tied into the AC System, then it has additional fans/blowers to push the air through.

Dude that Degreez option looks awesome.

Oh I see now, the blowers look just like the OEM ones. How about cooling the air though? I might be missing it but how does it cool?

If it ends up only being ~$500 I will be checking out that option as well

No idea, but they claim it isn’t just ventilation, it cools too. I haven’t had a chance to dig deep into how they work. I just know the Katzkin leather seems to have good reviews and for an additional $500, cooled seats are a no brainer.

Sit on ice cubes, works for me?

Even if u got the cloth seats and wanted to upgrade to leather, katzkin is probably a lot cheaper than factory upgrade plus you can add the cooling feature

Just like your house, takes the cool air out of warm air...

Do not know the science behind it, seems like voodoo to me but it works..

We have not done the cooling but I do like that option...

When we upgrade cloth to leather in the shop we use Katzkins they are nice, fit great and look like factory leather seats...

Refrigeration/Air conditioning (the normal version): Compressor takes a low pressure, low(ish) temperature gas (R-134, R-12, R-236, propane, ammonia, several work--some are dangerous), makes it a high pressure, high temperature gas (by putting in work). High pressure gas goes to condenser, cools (a bit) to a high pressure liquid. High pressure liquid goes to an evaporator that expands it to a low pressure gas. This process drops the temperature dramatically. The evaporator is in your airbox, and the blower is forcing air over it, so it cools the air. The low pressure gas returns to the compressor. Lather, rinse, repeat.

You can do something similar with thermoelectric chillers--you have a finned heat sink attached to a T/E cooler, and blow air across the fins. Running current through the T/E device pulls heat from the finned sink to the other side of the T/E plate, which is another heat sink, outside your "conditioned" volume.

In both of these, you generally put about 10-20W of power in for every 1W of heat you pull out of the air, which is why your refrigerator has warm air coming from the vents on the bottom.

Cooling 1 cubic foot per second of outside air from, say 90F to 70F is about 380W. That is probably close to the peak flow rate of an auto a/c blower, so about 1/2 Hp of cooling, 5-10 Hp pulled by the compressor...

Just what I said VooDoo...
