Comment on Is there a portable swamp cooler with a window hose like air conditioners have?

There’s no point as a swamp cooler does not have heat to reject.
Also, swamp coolers are only effective in very dry environments. Unless you’re in the desert it’s going to make it feel warmer by raising humidity significantly. A large part of why AC makes it feel nicer is reducing humidity, which allows sweat to work better.

I wonder if using a swamp cooler at the same time as AC would increase the efficiency 🤔

That’s a great question.
At first I thought it’d be a wash. The heat absorbed by vaporizing the water in the swamp cooler will be released onto the evaporator coils of the AC, so that’s a net zero energy transfer.
However, air is not good at conducting heat. This water evaporation/condensation cycle might transfer heat from the air to the evaporator coils of the AC better.
You are going to have additional water and electricity costs from running the swamp cooler though, so I really don’t know.

Could mitigate the water costs by draining the AC condensation into the swamp cooler 😅

I guess youd need some water purifier involved though, which would probably get rid of any efficiency benefits

No, AC reduces humidity while swamp coolers increase humidity. They would directly conflict and just waste electricity

In my use case I often don’t really need to change the humidity at all, I just want to cool down.
