Summer is coming and I need to cool a medium sized room.

I have used a portable air conditioner before but they arent very efficient. You used to be able to buy dual-hose ones but they seem to have dissappeared from the major retailers.

Does anyone know where to get a dual-hose portable air conditioner?

I wish delonghi would bring back the split mount systems that had the DIY install option with the quick-connect gas hoses.

This is a great question!

I have a 20m2 cabin in the back yard that needs a better heating solution than the current 2kw column heater and I bet when summer arrives I'll want cooling in there too!

I have a heat pump that I'd love to have installed but as the power being delivered to the cabin is *ahem* 'not exactly up to the standard a heat pump installer may require', a portable unit is what I need.

They seem to be available everywhere except NZ?

What's the advantage of a dual hose model?

Balanced pressure. An equal amount of air is sucked in from outside as is discharged outside.

With a single hose portable air conditioner, for the "Hot" side, air from the room is sucked in, heated, then exhausted outside through the pipe. Essentially this means that your inside "conditioned" air is being consumed by the process, and will result in outdoor air being drawn into the room to makeup what is displaced. The latter is not ideal for efficiency. if the outside team is more than the room temp.

We have an older single hose model. Has an impressive sounding kW output (and matching power consumption), but only really manages to cool a small room.

covers it. Assuming that the code works.
