Get an air conditioner with a scroll compressor. Ultra quiet and energy

But I don\'t hear the compressor, it is in the outside wall. What I hear

You mean the fan is running at its highest speed. That indicates so is the compressor. Your variable speed compressor is invariably highest speed all the time when it can\'t keep up with heat gain of the structure.

I said \"when it is running at full power\", meaning, the AC system,

It only takes a 100ppm more or less off optimum and you have real climate problems, which go either way too hot or too cold. PPM is a really scant presence, which should impress even the dullest person that CO2 is very powerful in that regard.

During the ice ages CO2 levels ran around 180 ppm. An ice age may be a real climate problem but we\'ve survived several of them.

What\'s this \'we\' stuff? You do notice the global population now stands at 8 billion and not 8 million. Living in a deep, moldy cave on a diet of mushroom and rodents may appeal to you, not me. An Ice Age is a climate problem.
It might be if we had one. That seems unlikely in the foreseeable future.

We aren\'t doing enough about anthropogenic global warming at the moment, but we are doing more than we were, and we will do a lot more as it gets more urgent.

We\'ve mastered the crucial trick, which is getting energy from renewable sources more cheaply than we can get it from burning fossil carbon.

The capital investment required to get enough renewable energy generation to let us dump all the fossil-carbon-fired legacy gear is large, and it\'s going to take while to happen, but we aren\'t going to end up living in damp caves on a diet of mushrooms and rodents - we never did (or at least not as a year round thing), and there\'s no reason to imagine that we will in the future.

Enjoy you alarmist fantasies, but don\'t expect to be taken seriously. You\'d have to have a better grasp of the facts for that to happen.

You just keep memorizing factoids about trillion year old \"-ene\" periods and see what that gets you. It\'s not useful.
https://en.wikipedia.org/wiki/Paleocene%E2%80%93Eocene_Thermal_Maximum

It happened 55.5 million years ago. I don\'t have to bother memorising that - Wikipedia reminds me every time you make some half-witted assertion about what anthropgenic global warming is going to do to us. There\'s a lot that\'s uncertain, but nowhere near as much as you like to claim.
The only difficulty here is finding someone who knows as little as you do about the subject.

Unbelievably, you only recently learned who is James Hansen, and then you dismissed the whole idea of Earth energy imbalance.

Michael Mann was interviewed today, and he is quite alarmed.

Michael destroyed the world, the Earths,
since money was poured into CO2 fake

Big money, $BsBsBsBsBsBs

At the same time water retention was killed globewide

So millions of seniors die today inhaling hot, dry air, contaminated with silicon dust, causing a yawning effect like that of an overheated dog

Use outside blinds to keep the sun away from the widow.

A nice trick for a single floor building is to install fixed blinds
2-3 meters outside from the building. The blinds do not start from the
ground but just over 2 m from ground, extending to 4 or 5 meters above
ground. When the sun is high up, it is blocked by the blinds but you
have an undisturbed horizontal view through the window. On the
outside, you can also walk under the blinds (which starts above 2 m).

The double/triple glassing is required to keep the hot air outside, it
is not required to keep direct sunlight out if blinds are used.

Right- the R-value of those windows is not all it\'s cracked up to be. That\'s where the thermal curtain comes into play. In winter they also hold the heat in. The curtains are all-season versatile. They\'re not cheap.

There is nothing to be said about such an elementary and self-evident process. Anyone who understands basic flow rate can understand a net gain in heat energy means higher temperatures.

Unfortunately for your reputation, the temperature of the surface of the earth is better thought of as an equilibrium between competing heat flows.

The light and infra-red radiation from the sun is a heat inflow and the \"black body\" radiation from the earth is a heat outflow.

As Joseph Fourier pointed out back in 1924 the temperature of the effective radiating altitude has to average out at -18 Celcius.

Anthropogenic global warming is all about how high in the atmosphere that effective radiating altitude is. Wittering on about \"heat imbalances\" is a pointless distraction.

The problem isn\'t the temperature of the earth as whole - it\'s heat capacity is huge - but the temperature of the thin layer on the surface that we live on.

Heat capacity of the Earth is minuscule compared to the solar energy impinging on it.

The heat inflow from the sun is 4.4x 10^16 watts. I can\'t find a heat capacity for the planet as a whole.

https://iopscience.iop.org/article/10.1088/0004-637X/757/1/80

makes if perfectly clear that the effective heat capacity of the surface of the earth is defined by the top 25 metres of the oceans.

The annual variations in heat flux get absorbed in this layer and shipped from the equator towards the poles in ocean currents.

On a snowball planet the annual fluctations are quite a bit larger, so the heat capacity of the planet is anything but miniscule. The heat capacity of the entire planet down to the core is huge, and seasonal variations on temperature get averaged out at very shallow depths - the temperature 50cm below the soil surface lags the surface temperature by six months , so it is highest in midwinter.

Michael Mann was interviewed today, and he is quite alarmed.

About what? Google didn\'t throw up anything recent, and your capacity get alarmed about stuff you don\'t understand is well established.

Who pays any attention to YouTube. It\'s blindingly obvious that we need to reduce CO2 emissions, but that\'s been blindingly obvious for about thirty years now. There are now more frequent unfortunate climatic events than there used to be, and I suppose it is worth getting excited about them in the hope of getting the attention of dumber and more gullible fraction of the population, but you should know better.

Are you saying the sun directly shines into the windows at that hour? Your windows must be on a slant, or you\'re confusing it with an ultrabright background full of reflection.

https://www.energy.gov/energysaver/energy-efficient-window-coverings

The modern energy efficient windows have a transparent metal film in them that totally blocks UVA/B radiation, and that technology works very well to prevent heating and damage from that part of the spectrum..

None of the sun blocking performance is to be confused with the basic thermal conductivity/ resistivity of the window. That has to do with heat leakage by conduction and is an entirely different matter.

The modern variable speed a/c technology should be controlled in such a way that it only runs high speed continuously when the measured temperature exceeds the setpoint by about 3oF, otherwise if runs at less capacity. An extended high capacity run means it\'s either trying to catch up with an extended setback, or the capacity can\'t keep up with the heat gain from the record outside temperatures.

Alternatively, why not make air conditioned beds (bed+tent+A/C)thus no
need to cool the whole apartment. It would also be easier to get some
relief to old buildings without A/C. Make the tent walls thick to
reduce heat transfer, inhibit any light entry and attenuate street
noise.

With such beds, one could have a nap during siesta or work night shift
and and sleep during the day.

The right blinds would stop that; the other trick, is broad eaves over the windows,
so in winter (sun low in the sky) you get direct sunlight through windows, but in summer
(sun high in the sky) they\'re in shade most of the day. It earns you about 5 degrees F
both for heating and cooling.

A nice trick for a single floor building is to install fixed blinds

have an undisturbed horizontal view through the window. On the
outside, you can also walk under the blinds (which starts above 2 m)..

You shouldn\'t have a problem with sun during summer. It is in effect directly overhead for the hottest part of the day, so it doesn\'t come thru the window.
It certainly does. It burns here from 11 (9 UTC) to 17 (15 UTC), at least.
Are you saying the sun directly shines into the windows at that hour? Your windows must be on a slant, or you\'re confusing it with an ultrabright background full of reflection.

The modern energy efficient windows have a transparent metal film in them that totally blocks UVA/B radiation, and that technology works very well to prevent heating and damage from that part of the spectrum..

None of the sun blocking performance is to be confused with the basic thermal conductivity/ resistivity of the window. That has to do with heat leakage by conduction and is an entirely different matter.

The modern variable speed a/c technology should be controlled in such a way that it only runs high speed continuously when the measured temperature exceeds the setpoint by about 3oF, otherwise if runs at less capacity. An extended high capacity run means it\'s either trying to catch up with an extended setback, or the capacity can\'t keep up with the heat gain from the record outside temperatures.


\"The modern energy efficient windows have a transparent metal film in them

you are completely wrong as always


what is offered is so-called venetian mirror installed as window glass

You have not considered the latitude and the orientation of the windows.

Satellite measurement of ground temperature in parts of Spain are at 60oC.

That is sunlit ground temperatures, not official temperature
measurements in the shadow.

That is a big YIKES.

60 C is just a cold sauna . Not really a problem as long as the air
is dry (wet bulb temperature below 30 C) and you have enough to drink.

One summer in the 1980\'s I worked in Saudi-Arabia with day
temperatures above 45 C, you just had to stay indoors during the day.
In the morning from the air conditioned apartment with an air
conditioned car to the air conditioned office and back in the
afternoon.

The main problem was the flimsy walls, doors and windows that leaked
heat inside and the air condition had to run all the time at full
power. That 24/7 air condition noise for weeks is quite annoying and
the only way to get a quiet time was to take a walk inn the desert
before sunrise, in which the air temperature was 25 C.

That\'s interesting, because the ancient architecture in that country
shows that they knew how to cool down their houses passively.

Maybe that\'s offered, too.
This outfit uses a metallic-appearing film for solar management

They also block UHF/microwave signals and it can be hard to use
cellular phones indoors.
