Yeah it sounds troublesome at first, but then you realize that digging a trench and laying some pipe is cheaper, easier and less maintenance than having a machine with moving parts and duct work and all that. In a desert I'm guessing in north america, the only things you have to consider are that the ground may be very rocky and also the pipe won't be in wet soil which will mean it will cool less quickly and you have to run a longer pipe. The good side is you're not likely to have tree roots crack the pipe and youre very likely to keep the humidity well below 100% even in the summer. I'd say go for it, deserts are very mold free. You might also consider radiative cooling with some of that super white paint that radiates heat faster than it collects, since you'll have less shadows and clouds it should radiate rather well, downside being colder nights and winters.
