What's the lowest temperature you can set your air con ?

16C in my casa and in the car the same.

There is of course a technical limit to the amount of heat the air con system can remove from a given space. Even set at 16 the house system works for ages to bring the house down to less than 25. Which is as it was conceived. One split unit to cool the whole house down is asking a lot.

Who needs air con?

What's wrong with strategically placed fans? Save a fortune on your leccy bill.

24 degrees is supposed to be the optimum tempreture for the brain to
funk*!`on~#....er guess I need ac

Yes, but at my age you need it for the "Tropical Moments"
(sounds better than hot flushes !!)

Even with fans billgates, I dont sleep well if the bedroom is over 25C and when the air outside at midnight is around 30C the air con is a boon. Money well spent in terms of purchase and running costs in my opinion.

Yup, true although there can be more than one cause of a hot flush

Yes ! When I get the electic bill !!

Why so? Lots of rechargeable batteries maybe ?

Well I wonder what you mean !!

If you set up something to mist water into the fan air stream, it's a lot cooler.

There is a lot you can do to cool things without paying thru the nose.

The Regina Hotel in Sevilla has a super internal courtyard about 5 stories deep which is shaded by canopies drawn across at roof level and a central fountain which is a fine spray and tinkles onto the pond. Just to listen makes you feel cooler but the water mist really does help. All this is very Moorish and the prime example is the Alhambra!

The moors understood how to cool areas down. Looking at their strategies can be very rewarding.

Thats just what we have done and we will have a fountain head with a rill leading to a spill pond and an underground pipe to a lily pond at the end. All this in our internal courtyard covered by a pergola.

If you have some canvas screens up, wet them with a fine bore pipe, and that will give a down flow of cooler air.
