KENDERV engine: closed circuit heat engine

[Remundo]

Yeah but it's not him who contacted me.

I feel that the one who wrote to me was sincere and uninterested. I preferred not to mention it on the one hand because he wrote me in MP, on the other hand not to mix it with this Mr. Gas and Heat which seems to me smoky and hot .

Finally, if they want to show up here, they have complete freedom

Hello everybody

I just stumbled on this thread that I traveled diagonally

Mr. Cousin's system looks like features to a cooling circuit air conditioner (or heat pump)
He uses the H2 at a controlled pressure as a refrigerant

Hydrogen is certainly the most "fluid" fluid which allows the best exchanges in an exchanger.

after it's a question of COP

But in fact, it requires a hot source (condenser, rejection of the energy by condensation of the fluid) and a cold source (evaporator, absorption of the energy by evaporation of the fluid)
and in between a compressor and an expander

apparently, he replaced the regulator with a turbine, certainly, but the energy recovered at the trigger is negligible, the energies in question are thermal, so how to convert them into mechanical energy?

So Mr. Cousin, what is the COP of your machine?

[Christophe]

Radio silence Mr Cousin?

for a refrigerating machine the hydrogen is worthless

it is worth more a gas which is liquefied at the right temperature: the heat of vaporization is much superior to the heat of compression and relaxation of a simple gas like hydrogen

with a refrigerating gas that liquefies, the relaxation represents a very low power that can be forgotten without much loss

with a perfect gas like hydrogen, the recovery of the energy of the relaxation is essential otherwise the yield is dismal

[Christophe]

And the H2 diffuses in the materials ... but the H2 is in fashion ... here is pkoi I think the inventor withheld this gas ...

[recyclinage]

at the time of gallilage everybody thought that the earth was flat

nothing creates nothing nothing loses all this transforms


I do not think that the painting of Mendeliev is complete

and I think any combustion brings pollution

what is flammable brings some calamine whatever it is composition

if I remember well at the time people were told that it was good to smoke and drink

a few decades later the company backtracked into the opposite

all I know is that I do not know anything

[Remundo]

And the H2 diffuses in the materials ... but the H2 is in fashion ... here is pkoi I think the inventor withheld this gas ...

Fashion effect, maybe ...

I rather think that he chose this gas because it is one of the rare ones that does not liquefy at -250 ° C and that it can be produced from water, thus allowing "in the mind "to have a gas turbine without being bothered by changes of state.

For diffusion and inflammability problems, sure that Helium would be a better choice.

OOPS, there is an error in following my cycle:

Hmm ...
no state transformation phase of the fluid, just in the gaseous state, the specific heat of hydrogen is very low ...

Cycle:
1 energy absorption with an exchanger, let us admit a fluid at -250 ° C at the exchanger inlet at 200 bar, the delta T is enormous !!, either the "evaporator / exchanger" is small and completely frosted or the gas (of low specific heat) rises to ambient T ° immediately in an oversized exchanger

2 and 3 Relaxation, by a mechanical organ, delta P: 180bar, ??? at what temperature does hydrogen go down? -250 ° C? let's admit but at 20bar

4 compression, from 1.2 to 1.5 which unit? as the exchanger is supposed to be at 200bars, 20 will have to be compressed to 200bar, which is a compression ratio of 10
but the compression raises the temperature of the fluid, at what temperature? it depends on the energy restored to relaxation ...

blows, the fluid is not at -250 ° C far from it
Then the fluid absorbs energy in 1 to stay at 200bar, so on ... must see

What energy to the compressor?
Qty of energy absorbed by the exchanger?
Mechanical energy restored to relaxation?
COP of the system?

difficult to contain hydrogen

A video of zinzin?

[Christophe]

-250 ° C ... how much place (lab) on earth at this temperature?
10, 20 ... 30?

[Capt_Maloche]

and given the explanation of the type I quoted, he does not hear much in fluids

there is no change in the state of the fluid, so you can recover the energy in mechanical form, but you need a volumetric compressor

the fluid is not maintained at -250 ° C, it is like in a refrigerant circuit evaporator, you maintain the pressure and the gas gradually absorbs the energy
that's why the turbo does not hold the road
it is not waterproof
