Will check. Thanks.

Hey, Ronnie - I thing this wind bag posted again.

How the eff about that? I say God Damn, this punk is clueless.

However there is plenty of information here I have posted that lets anyone who thinks with their brain GET IT

Seriously, you are going down.

The trolls will see to that.

Takes one to know one, you festering puss wound.

Noooooo - say it ain't so, Archimedes.

KeloGes: NO response?

I'm in the dark completely on this one, please explain..



Guages in focus for clarity.

Close this thread, please.

Amen.

Actual technical content here is zero.

"Hints" are no basis for a technical forum. Put up or shut up.

[KelogGes]

This top picture shows the GAUGES actual reading high side PRESSURE and low side PRESSURE of the REVERSE THE GASES TEST and meter IS SWITCHED ON (LOOK AT THE DIGITAL DISPLAY)

THE LOW SIDE PRESSURE WAS ONLY about MINUS ZERO -3 OR -4 LBS

THE HIGH SIDE PRESSURE WAS ONLY about 126 LBS
And this achieved @ 85 degrees Ambient inside the shop
Engine RPM 2000

Total R134A Refrigerant used was only .95 lbs, which is all my PFC's require to get
32 degree vent temps @ Ambient 92-95 degrees

That was further verified and proven in SEVERAL driving tests at higher ambient temperature tests





THE bottom picture SHOWS Gauges IN CLEAR focus for clarity. so you know what the top gauges show you cant read as well

[/QUOTE]

bottom gauge picture is switched off has no electricity and is used for clarity understanding of the top picture the 911 engine is switched off

But isn't there a conflict between -3 PSI suction pressure and 30 PSI vent temperature?

Plus which, my factory system(cabin heat blower off) easily gets ~30dF (max low) vent temperatures in the same situation, 2000 RPM and 85dF OAT, noting to beat your chest about.

Exactly! Ambient of 85F is not asking all that much of even the stock 911 system.

That's been my primary complaint about Reid's a/c shenanigans since his first appearance in 2011; nothing wrong with thinking of new ways to do something, but to claim that one's "new ways" and/or new components relegates everything else to obsolete-garbage status, and then show evidence that definitely does NOT support that claim, makes zero sense, and in fact, equals "trolling".

This is the underside of THE TAN SWAN which also has this invention

[KelogGes]

The Black Swan gets vent temps between 35-37 F average with Ambient temperatures 92-95 F without freezing up after many test runs in all kinds of driving situations

South Florida normal highest temperature is 92 F however we had a record heat temperature of 95F during a/c testing on this 911

We have a subtropical climate with a lot of high humidity

BTW When testing I always use lowest evaporator fan blower speeds, this gives the coldest air vent temps

[db_cooper]

At 2000 rpm your pulling a vacuum! on the low side and 126 on the high side?

I would normally say the expansion valve is defective (almost closed) it is not passing refrigerant effectively and not enough refrigerant remaining on the high side for the compressor to pump up normally. You may get some uber cold vent temps with HC12a with those pressure readings. HC12a gets very cold when undercharged..which is what the pressures act like too.

A/C compressor won't last long though pulling a vacuum on the low side all the time. No oil flowing in the refrigerant and hard work on the compressor internals.

What was the evaporator inflow cabin temperature? 80dF, Good-O!, 65dF, not so good!

Yes, lowest blower speed will yield the lowest vent temperature.


Bold text by WWest

But that is by no means the best way to take the measure of the system performance wise. Most BTU's will be moved at the highest blower speed provided the TXV has enough liquid refrigerant available for full open metering.

Think about how good a system would be if it could do that at full blower speed with evaporator inflow temperature just a tad above human comfort level, say 80dF.

You talk about reverse the gases but you have yet to explain just how it's done. Now I am not a rocket scientist but I do know a little bit about A/C and how it works regardless of it being in a car or in a house.

So I have to ask - just where are you reversing the gasses - or is that a trick question but instead should be "where are you reversing the flow of the gases".

The only time I have ever experienced "reverse flow gases" is on a heat pump and none of the cars that I am aware of have a heat pump design.

Secondly you show a picture of the high and low pressure side of the refrigerant lines. Well I have to ask - you comment that the low pressure is around 3 or 4 psi yet the temperature of the air flow is around 35 - 37 average temp.

If you are using 134-A refrigerant the temperature at 3 - 4 pis would be around -5 to -8 degrees F.
In addition to that you also include in your comments that you only use around .95 lbs of refrigerant.

I have to say you surely have me baffeled because if you measure the diameter and length of the lines to get the correct volume, and calculate the volume of using two condensing units there is no way you are only using .95 lbs of refrigerant.

If what you say is true about the amount of refrigerant, then the lines would have to be around 1/8" diameter along with the condensing units.

I think you want everyone to believe that you have this great invention that you won't tell anyone about and want us to believe you know what you are talking about -

But I really don't want to say it I don't think you know what you are talking about. For if you did you would have explained it already.

And as far as your concern for others taking away your secrets, I don't think you have any to be taken away.

I have been working in the HVAC industry since 1965 working on chillers air handling units, ammonia systems and anything else related to the HVAC industry.

I know you can make water boil at 33F under the right circumstances but when it comes to claiming that you can keep an evaporator coil from freezing based on your pressures of 3 or 4 PSI that reaks of not knowing what you are talking about.

You can claim to get the condensing coil temperatures down with your PFC but that's about as far as you can go with your claim.

Unless you can provide a descriptive flow chart showing just what you are talking about when you speak of reverse gas flow - you will continually be discredited because no one believes you know what you are talking about.

Now don't take this as a criticism but take it as a response from all your posts from someone who has been working in the HVAC industry for quite some time.

And should you do want to discredit me by saying I do not know what I am talking about, you are going to have to prove me wrong by you coming clean with proof - not just by saying I put it out there you figure it out. Any dummy can do that.

Reversed gases = heat pump.

Rerouted gases would be a far better adjective.
