Portable A/C vent into fireplace?

I didn't say the water vapour entered the room

bzzt, wrong answer

somewhere yes, where is controllable. It need not be indoors

It's like wrestling a pig mate. ;-(

He makes a statement, shoots himself in the foot, then tries to justify himself with BS. ;-(

We have seen it here over and over ... ;-(

Ah. So you have zero interest in reality. Mkay.

I have every interest in reality and keep asking you to explain it (which would *obviously* make me look silly, if it's as obvious as you suggest), but it's not 'clever' setting up some bizarre scenario with yer swamp cooler in an arid outbuilding with a heat exchange between that and your house, we are talking of the *typical* use of a swamp cooler as might be considered by 'most people'.

Same with the mobility scooter ... I'm talking about 'connects to the speed controller' and you, because you think doing it quickly is of any relevance or interest to me, tell me 'you would have done it by now' and 'just solder it' but then fail to explain what you would 'just solder', pretending it's obvious.

The 'reality' in both scenarios you *have* shot yourself in the foot and because of that you are going nowhere.

Just cut the BS and fess up ... or come up with a valid answer(s) / explanations and we can all move on.

Especially as one of the great joys of proper AC is the dehumidification. Even without a temperature drop they would make the place feel much more comfortable.

So out of interest how does your swamp cooler manage to separate the cooled air from the humified air? Does it have an air to air heat exchanger and secondary fan (or at least air path)?

Except that desert coolers work well in very dry air which is improved for most people by being made more humid. We lived in Riyadh in the 1970s and desert coolers made life much more comfortable by both cooling *and* humidifying the air.

Yup. It's like when people come back from holiday in hot dry countries, tell us the temperature there and we equate that to the discomfort we would suffer (as you say, from the humidity) at similar temperatures here.

Daughter runs a dehumidifier in her bedroom for drying their clothes and said that whilst it was about the same temperature in there as the rest of the flat in this weather, it didn't feel as 'sticky hot'.

I'm guessing the de-humidifier would lower the RH (to below ambient) and in so doing dry the clothes faster, eg, it (the clothes) wouldn't make it more humid (although it might rise briefly when she hangs the washing up and before the DH has kicked in properly)?

Cheers, T i m

They do. But in comfort terms this isn't much different to lowering the temp. Either works.

If one were to install something, what I'd suggest considering is passing (incoming or recirculated) air through a pipe covered with shaded wet soil. All you need is a fan, and you get a little cooling for your 20-40 watts. With other basic heat preventing measures such as shading this can keep a house pleasant at trivial energy use & cost. The UK really is not hot enough to need refrigeration ac.

What I do here (in heatwaves only) is far cruder. The flat roofed extension, despite being fully insulated, is like an oven in a heatwave. Flood the roof with water & that effect stops. It no longer heats some of the rest of the house. It could hardly be simpler, and no, no water vapour is added to indoor air.

I also use differential thermostat controlled ventilation - that's my main go-to. When it's cooler outside, ventilation runs. It cools the masonry over a period of hours, leaving the house cooler through the next day. 20-40 watts cools by a varying amount upto 6C. In the first property I did this, due to poor building design it gave over 10C improvement.

After this year's heatwave I think it's time to consider installing some sort of automated & permanent swamp cooling. The variations & permutations are numerous.

And yes, swamp cooling is effective. Installing ac in the UK has such downsides that really it just shows a lack of comprehension of the situation. It's a bit like getting a car just to go 10 yards.

So not a "crude swamp cooler", but one incorporating a heat exchanger.

This is what most would call a "crude swamp cooler".

Yup, as I predicted then, he's just being dissentious (as usual after you pin him down on one of his crazy statements). ;-(

And I suspect 'just solder it' (Mobility Scooter thread) is just as much BS as this 'crude swamp cooler' thing.

Cheers, T i m

p.s. And look at all the swerving about with pipes though mud, water on the roof and other things he's thought up but not implemented. ;-)

Yes, 'there would be a 'comfort window' of both humidity and temperature (and direct / indirect heat from the sun, wind chill factor / psychological impact of moving air etc) so therefore where a 'swamp cooler' would both work and where the side effects that would be negative here be an advantage.

When we were at the Eden Project there was a little wooden shed with aircon in it for people to 'chill out' if they were overcome. I believe it was in the Tropical (not arid) Biome. e.g I don't think people weren't suffering from just being too hot.

Cheers, T i m

In your humble opinion obviously...

So is that what you meant by "I use a crude swamp cooling setup here when it hits heatwave"?

But not for doing many of the things that people buy AC for.

More to the point, in the form that many people experience swamp coolers (i.e. COTS evaporative coolers, wet towels draped over fans etc), they don't work very well in our climate.

And yet so many people do it. Perhaps they have heat generating equipment that can't be turned off. Perhaps they have medical conditions that put them at risk in high temperatures or high humidities, perhaps they want better productivity from their workforce and have found that keeping them cool and comfortable pays for itself many times over.

Tis the thing about armchair experts, they can make all kinds of statements to appear to be worldly wise and possessors of great knowledge and experience, that which would be within reach of the common man, if only he were not so blinkered or narrow minded.

Of course the problem comes when you try to drill into the detail, and find there is no actual depth of understanding, and much of the "experience" is actually either someone else's (several times removed) or just complete fantasy.

That's the point at which they normally switch tactic to insulting the inquisitor, to try and divert from the actual discussion.

Yup sure, in hot arid climates, evaporative coolers are a win, win (assuming there is not a shortage of water).

Its also common for many traditional buildings to take advantage of the situation with evaporation pools, large roof overhangs, central quadrangles with planted vegetation etc. There is a whole art and science to passive cooling. Even the traditional earthenware jug will cool water effectively in that kind of climate.

Alas much of this does not translate well to soggy old England.

It also makes the bodies own temperature control mechanism's work that much more effectively - sweat can evaporate more easily, and cool you down, rather than just making you clothes feel more "clingy".

Lowering the temp will help, but if its offset by an increase in RH you don't get much gain in comfort.

The thing is, some here do seem to 'blow hot and cold', affected by the phases of the moon ... or their meds / week / life possibly?

I work on the basis that if I know I say, if not I'll ask and if I can help I'll try and that we are all 'mates' here (in the support of the common 'd-i-y' goal). I know some have their own personal problems but that's the case in any social group.

This was something daughter was reflecting (and she's now appreciating) when we were out on a long dog walk the other day ... that as she's got older and not only looking after herself, but her half sisters daughter, just how useless many people are and how much BS they try to give her ... something she's never heard from me. AFASC, I either know something or I don't and I'll tell her so. However, even if I then give her my 'best guess' it's often reasonably close.

Classic response, especially when you raise any issue which means people might have to question their own ethics (slavery, BLM, eating animals, inc fish, or is it mostly our own plastic waste these days): ;-(
