Re: one room ac? said by TA63:The ones that duct heat to the outdoors are venting air from the conditioned room.
This air needs to be made up somewhere. The result is an inefficiency.
Not always true.
There are units with 2 air exchange ducts, one for intake to cool the coils and one for exhausting the HOT air. You can take air from outside and exhaust it outside as well, that air doesn't mix with the air from inside. |

said by Chinabound:I've seen 20'-30' extensions on some systems in China. If I'm thinking of the same one you're thinking, those extensions are for units that are 5 feet tall, so I imagine they're MUCH more powerful. Those can handle a much longer extension (relative to size). |

kudos:1 | Perhaps you should look at actual product specifications. Fujitsu 9RLFW I believe is their smallest unit (less than a ton) and the line set can be up to 66'.

said by PeeWee:Is there such a thing as a portable ac unit for one room that is not a split unit that wouldn't require a duct to the outside? I need to cool one room where I cannot create any penetrations. I did a kludge solution for a grandma long ago. The absorbed heat went into an oil drum filled with really cheap (rice bran) wax.
The side effect was that late at night, the heat was slowly released back into the room and grandma was quite comfortable until she passed away. |

Las Vegas, NV | Portable evaporative cooler would be best option if you lived in the desert like here in Vegas. But over where you are humidity would be a problem, here with 10% humidity it hardly makes any noticeable humidity to the room. |

What is the heat of fusion for rice bran wax? How long could the AC run until it was all liquified? Did it all re-freeze during the off time?
That also sounds like a way to run electric heat while on a cheaper time of use rate (at night) and get heat out during the day as the wax froze.
Brilliant! |

1 edit | Rice bran wax absorbs about 800 BTU per gallon (200kJ/L) while softening around 70C.
I am thinking a few Peltier CPU coolers could chill salt water and dump the heat into wax for an almost silent system. I will experiment this summer and see how quickly I can get molten wax back to solid.
Main problem in USA/Canada will be sourcing rice bran wax from China/India or carnauba wax from Brazil. |

How much cooling do you need, and what are you trying to cool?
That's going to help narrow down the options.
There are some high-tech (read that as high dollar) options that could work, in very specific circumstances (google Peltier effect coolers for some examples) - but you're talking high bucks...
I have water coolers as backup cooling in some of my small equipment rooms - also effective, but can require a fair bit of water, too...
If it's for residential, then a mini-split may be your best option... a 2" hole would be about all that's needed - and the 'outside' unit can be some distance from the inside - with a little flashing and fancy trim, the lines wouldn't be that distracting at all... |

Have you considered mini duct systems like Space Pak or Unico ?

Can you vent out a window? This is your only option. |

If you can install a small vent or have access to a window a portable A/C unit would be the easiest and cheapest option.
This unit has a heat pump as well.

I thought I had made my decision. Then you show me something competitive with the same brand item I found at Costco.

The Costco unit is 12,000 BTU's (450 sq. ft.) with no heat. The Walmart unit is 13,000 BTU's (500 sq. ft.) and has a 3,800 watt heat pump. Not to mention it's $100 cheaper.

Buying this one (I think) tomorrow.
edit Glad I asked here instead of just buying one. This deal is hard to beat.
