Evap air cooler & dehumidifier possible?

Portable AC units are out of the question due length limitations of those tiny-ass little hoses that vent out a window. Did some research on evaporative air coolers, and found out they only work in dry climants. RH can peak at 65%.... so I was wondering if I can use a dehumidifier in junction with the evap air cooler to cool a room.

No. That is how they cool is the evaporation of water. Swamp coolers are only good in the desert where the low RH and the evaporation of water via the pads is basically a balance like yin and yang.

Most likely a dehumidifier will raise the temps that the cooler just lowered. Seems counterproductive to me and just more electricity is wasted.

Get a sump pump and the clear hose and you can pump water anywhere,from a A/C unit.What i do for a living HVAC.They do make them where water drains in a catch pan you just have to empty it.

In the hot months, which thankfully are few where I am, I'm stuck using the central air so June through August my electric bills are always very high. I've looked at many opinions and a portable A/C with the right exhaust set up would work best for me but it would cost me 600+ for what I need and my temps just aren't that big of a deal for too long for me to invest in one. If i was in a steady warm and humid climate and couldn't use a swamp cooler I'd buy and setup a custom portable A/C system. The thing most people forget about for both A/C's and de-humidifiers is their exhaust's blow hot air so that has to go somewhere.

I use a window AC. And how I handled the water drip is this. Pulled the cover off so I could see everything. Found the best spot to dill a hole. Used a 3/4 res fitting. So it was a big hole. After drilling I used a hammer and a pipe to beat a dent and make the hole the lowest spot. Added the fitting and put it back together. Placed the AC as high as I could. Put a hose on the fitting and ran it outside. Hose can't ever go higher then the AC. Or if your unit is clean you can just dump it into a res and use the water to feed the plants. It's basically free RO water.

a chiller and heat exchanger (transmission cooling coil) and the right fan , hydro innovations makes an ice box which is a coil enclosed in a plastic housing with 8 or 6 in round connections.

It's empty now. Thanks for telling me. I get a ton of pm from people asking for help. If you want that info I'll post it here. I just read your pm before I looked at this thread.

can you run a swamp cooler in a closed room, with a dehumidifier to lower the RH allowing the swamp cooler to work properly?

there are all kinds of problems with running a dehumidifier, first you dont want to dry out your grow room too much, then it produces heat as it operates, which just ads to the original problem.
what size are the portable ac unit vent hoses? if you could hook them to a 4 or 6 inch adapter you could put a good inline booster fan a little before its stated limit and it would extend it considerably. something like this
