BS or Refrigeration Breakthrough?

It would appear to me that the key to all of it would have to be the design of the metering device, and the (assumed) fact that there would need to be more than one, i.e., constrict the amount allowed in to the condenser, and that coming out of the evaporator).

I didn't think heat transferred from a cold region to a hot region. That kind of goes against the principals of heat transfer doesn't it?

And I remember the 150 MPG carburetor that was bought up by the oil companies/auto companies/government to keep gasoline prices high.

whaat is the second law of thermodynamics?

[John Jamieson]

"Clausius Statement", the second law.

[FreePaul]

My family had an ammonia-absorption-cycle refrigerator (an Eletrolux, I believe) in the 1930's into the 1950's. It ran on natural gas. I remember that every time we had an electrical power failure the neighbors brought their butter and other valuables to us for preservation.

"It is impossible to construct a device which operates in a cycle and whose sole effect is the transfer of heat from a cooler body to a hotter body." (without the input of work)

they store large quantities of snow in underground caverns and use that for air-conditioning during the summer.

I'm going to look at this for summer cooling in Houston. Thank you for the suggestion. Do you know where I can get a large supply of snow?

[Down South P.E.]

The second law says basically that "heat will, of its own accord, flow only from a hot object to a cold object." Like I said heat flows from a hot region to a cold region. Isn't that what I said? Let me go back and look.

.....leave your freezer door open ;^).....

I wasn't suggesting it for your house. These systems are generally used where large - large demand loads are required. If the humidity isn't too bad there in Huston (and I don't know what it is) why don't you look into evaporative cooling or "swamp coolers". I know they work good in Arizona where the humidity is low. All they use is a little electric motor too.

[Rustynailww]

thanks, is there a first law?

[Down South P.E.]

The idea is to produce ice during off peak power demand - when the electricity is cheaper. Then use the ice (stored in well insulated containers) to cool when power is in peak demand and cost more.

Actually, there really is a high MPG carburetor. Its used in tanks. It doesn't work well with normal gasoline (the additives kill it after a few days). If one was looking for a conspiracy you could possibly claim that all of the "additives" were developed partially to prevent its use by the average joe.

Fine. Let's see one work. The illustration suggests a reverse Rankine cycle (like a freon unit) using a working fluid that must go through a phase change. As is noted in other posts, it looks like there is not nearly enough head developed to compress a gas to its saturation pressure by spinning it in an enclosed vessel. If it did condense, it would remain in the tubing at the larger radius as there is nothing to force it back "uphill" toward the expansion valve/orifice at the smaller radius of rotation.

The end result of the device in the illustration would be stagnation - no flow through the tubing at all. Sorry.

..one side of this device is much warmer than the other side (one would hope). Also, notice in cut-away diagrams, that one side is wound one way, with a closed return though the center, and one is wound a different way. That creates a low pressure side and a high pressure side. Just follow the arrows in his diagram.

Thanks, I didn't notice the inner return coil was wound in a different direction. My gut still tells me the evap section should be a smaller diameter than the "compressor" part. IMHO this is not a scam. As I stated before the real question is what is the BTU's / HP. Also as stated elsewhere balancing something like that at 10 or 20 K that is exposed to dust and dirt would be a challenge.

during off peak power demand

.....interesting.....

.....Duke Power has had great luck with the same concept in energy.....

.....(Bad Creek).....

[Down South P.E.]

The first law of thermodynamics basically says "The energy going into a system, minus the energy coming out of a system, equals the change in the energy stored in the system." This is simply the law of conservation of energy. Real rocket science huh? The words are simple the formulations and calculations can be difficult.

Sorry I missed your point.
