Simple Air Conditioning for those suffering from the heat. & DON’T FORGET THE ELDERLY & poorly people

Hi all,
thought this may help some of you & any elderly folk you maybe keeping an eye on, to keep cool or have a good night sleep.


1 small ventilator

+/- 5 plastic bottles full of water full to 1” from the top & air partially squashed out of them.

1 washing bowl to accommodate the bottles

1 deep freeze to freeze the bottles of water.


Freeze bottles of water in deep freeze

Place washing up bowl in room required (at night in the bedroom ½ hour before bedtime) don’t forget to close window & doors.
Place frozen bottles on bowl
Place ventilator in front of bowl with frozen water bottles & set at lowest speed.
Hey presto you have your own air-con unit.
5l of frozen water ventilated in a room of 20m² will bring the room temp down replace bottles of frozen water a frequently as required.
It’s simple thermo dynamics but may help some elderly folks that you know.


All ideas gratefully received …:hugs::hugs::hugs:

I am going to give this a try tomorrow.

you can put the frozen water bottles on a plate, the plate or bowl is just for trapping the condensation coming off the bottles.
Better to put the bottles just above & behind the fan as cold air falls & as such cold air is sucked into the fan & ventilated out into the room. Of course the more bottles of frozen water the better cooling.
I said 1/2 hour before bedtime, but better a few hours before (don’t forget to keep the doors & windows closed in the room) & change the bottles for new ones at bedtime (if needed) as the walls floors etc will all have heat radiating from them.
Let us all know how you get on.

Warren, a bit of a dumb question coming up!, but do you think this may work with one of the new ‘blade’ type fans, (dyson ) ?

I fill my rubber hot water bottle with water and put it in the freezer. At bedtime I wrap the frozen ‘hot’ water bottle in a tea towel and, when cuddled, find it keeps me cool during the night.

Aha… we have one each… tonight we’ll give it a try.

As long as it pushes air around the room

Thanks Warren, I’ll have to find bottles & give it a go!

@Wozza. - right experiment started at 22:10 temperature was 31.6 degrees. Room is approx 12m2.

6x 1.5 litre bottles of frozen tap water.

Fan is Rowenta Turbo Silence pedestal fan - these are absolutely superb fans - fairly quiet for the breeze they create but a bit pricey, bought from Amazon Germany a couple of years ago.

Windows/doors now closed - will check at 23:10.

Phew… thought ours was a trifle warm at 27C… we’re going to put socks and pillow cases in the freezer…

36.6 degres must be nice & toasty. What the temperature now?

I am sorry to say that even after 2 hours the temperature has not gone down at all.

In the bedroom next door with the window open the temperature dropped by 2 degrees.

A great shame as I wanted this to work.

Noted difference in my bedroom but don’t have a thermometer to measure

On Jeremy Vine this morning, Amanda Prowse - one of the panel - suggested placing icepops under her boobs as a way of keeping cool with the added benefit that when the icepops melt, you can simply drink the contents :ice_cube: :rofl:

i’ll try it next heatwave
