design climate data for mexico cities

design climate data for mexico cities

(OP)
Does anyone have a good source for design cooling climate data for Cabo San Lucas?  I can't get that close using ASHRAE Fundamentals and am into a bit of an argument with a local contractor who uses a "rule of thumb" to establish cooling loads.

Thanks

RE: design climate data for mexico cities

there is not a lot of data in the HOF even with the CD for Mexico.

Do not look down on the local contractor too much, keep in mind that you are not in Kansas any more toto

Maybe figure t out on your own

you can look at a fair bit of weather data

Take the "V" out of HVAC and you are left with a HAC(k) job.

RE: design climate data for mexico cities

For a modest fee + per diem I would be glad to go to Cabo and compile weather data for as many years as you care to obtain.

Thanks for the link Abbynormal.

Don't think I've not suggested the same idea to my client MJ.

RE: design climate data for mexico cities

If you had someone in your office who spoke Spanish, you could possibly call down there and talk to the airport or weather stations who usually keep yearly logs on temps, wind, etc.  If not use a similar latitude close to the one you are looking at and use ASHRAE again.

RE: design climate data for mexico cities

weather under ground has the airport data

RE: design climate data for mexico cities

And English is the international language of aviation, so the airport weather office staff most likely speak it.

For sub tropical region I would base my ambient conditions at 120 dF and 100% RH without any trees surrounding the acienda. With trees covering the acienda, use 100 dF and 100%RH

RE: design climate data for mexico cities

you will never find such conditions anywhere on the face of the earth

RE: design climate data for mexico cities

OK AbbyNormal, what would you consider for design ambient conditions for lack of any information?

RE: design climate data for mexico cities

I'd barely design a steam room for 120F and 100%RH. Typically a steam room at 105F is sufficient.

I've decided I need more tropical clients. I could really use a site visit in Cabo San Lucas right now...

Sorry to be anal, but you could not even shed body heat by evaporation under those conditions. All the Indians would have died, no one could live there.

I looked at last year, they can hit 100F or so, I never went and picked a wet bulb to go with it. But that site showed they did hit a dewpoint of about 84F, which I get down here sometimes, so I would make sure I could hold humidity under control when a tropical system went by and it was overcast, no sunshine and an 80 dewpoint. So call it 80F and 80%RH to size the moisture load.

Any system that can handle that as well as a drybulb up around 100 (when it will be a lot less humid) would be fine
