How to cool the air without increasing humidity?

blackcloud

Hello all

We are trying to find something to buy to use to cool the air but not increase the humidity, we were looking at portable air coolers but they all use water in them which would increase the humidity.

Can anyone recommend something portable which will cool the room but not increase the humidity, dont know if theres a Dehumidifier that cools a room out there? or something similar.

Air conditioner? Should be around £300. You need to have the window open a little and run the hose outside for the warm air to escape the house.

You need a portable air conditioner .
You will also need a pipe and hole somewhere to pump the hot air generated outside.
something like this

Thanks I was looking at that but an air cooler works by evaporating water to cool the air, since as heat energy is absorbed doing so, this lowers the air temperature. As a result, a portable air cooler requires water to operate and some models recommend adding ice for better effectiveness. The catch is that as they add significant humidity to the air. Which is what I am trying to avoid, any ideas?

You are confusing air cooler and air conditioner. The cooler requires water to operate, whereas the conditioner linked to above in post #3 works on the same principle as a fridge. These will also dehumidify the air significantly.

You are confusing two different systems, an air conditioner will lower humidity while an evaporative cooler will raise it, as previously mentioned you need an air conditioner.

Thanks, please correct me, so in post 3 this would not raise the humidity? but I thought because it took water it would raise the humidity?

How about this?

Would this raise the humidity? can anyone recommend one which is cheaper than in post 3 which would not raise the humidity?

I see what you mean now

Portable air conditioners use refrigerants to reduce the temperature. During the cooling process, moisture is condensed out of the air and collected in a drain bucket or exhausted out through a drain hose or evaporated out the exhaust.

Evaporative coolers use the simple process of evaporation to provide cooler air. A frame with a large fan is walled in by water-soaked pads, and this fan blows the warm outside air through the continually soaked pads to produce a cooling effect. As a result, the air can be cooled by as much as 20 degrees.

portable air conditioners act as dehumidifiers

It would help to know why the heat is there e.g. Is the heat source “natural” building construction . poor insulation, large window facing the sun, conservatory, poor ventilation etc
Or more a "man made" type e.g heat from appliances, machinery , kitchen, stove boiler etc also where, when is cooling required at night in bedroom, during day in living room etc residential or commercial (home or business)

It can be as simple as creating a cross breeze it maybe complicated and require a full ventilation /conditioning system, The generalisation of its hot I want too it to be cool how do I do it ? not going to get best results without further info and could well add to heat and cost more but achieve nothing ?

Only an air conditioning unit will do as you want.

If I were you, I wouldn't go for a portable unit. I've got Ductless Split System by Cooper&Hunter (you can look at it on comfortside.com/ ). It cools the air really effectively. Overall, this system provides proper temperature or humidity control.

That's an American website. The OP hasn't told us what their budget is, but those A/C systems would seem to cost in excess of £1000.
