Well, if you turned off the radiators, there would be an absence of heat. And absence of heat is cold. So yes, technically speaking, using radiators(or rather, NOT using radiators) could cool the house.

You are missing the point, the idea was to pump cold water (very cold water) through the central heating system, to make the radiators colder, and by doing so to cool the room more and maybe remove some moisture too.

I think we understand your idea. There are just two comments to make (in the context of the UK).
1. You need a refrigeration unit to produce your cold water (unless you live next to a mountain stream). So it costs you.
2. Your radiators will be dripping water all over the floor and may not cool the room very effectively, in any case (they would need to be near the ceiling).

Why do you think it is not done already if it such a good idea?

Teathing problems

Why not open the windows instead of using the air-freshenrs, easier and it is free too.

That's what I do every summer, as I get a nice draft through my home.

I tend to agree; air con is pretty essential in some countries if you can't build houses in the traditional way but, in the UK, wear shorts and T shirt and ignore the sweat.
As for "teething troubles" has it even been tried?

Well exactly.
 
My idea was that cheaply, every home in Britain could have a few modifications done to the central heating system; and hey-presto, a cool home in the summer. Therefore the central heating system is set, it's all add ons.

You could however design a totally new system. But I don't think either idea, has actually been experimented with.

Have you ever done any plumbing?
You would have to provide drainage from every radiator in the house; gravity operated would be unlikely to work. How would you arrange for that? And what about the poor efficiency of the system. And have you considered the capital cost plus the running cost, bearing in mind that it would be very inefficient?
The heat circulation system is the least of the problems associated with air con.

Hi

I am interested in this topic.

Sooyeah - have you had a chance to experiment some of the suggestions? What was the outcome of the same?

Thanks
