The idea of ​​a simple heat pump. Alternative for the winter

I welcome all fans of alternative types of energy! smile

Here came up with the idea of ​​a simple heat pump that will automatically start to work at a negative temperature outside the window. Such a pump can produce a little electricity, and then turn it into heat or spend it on some of your needs.

For assembly, you need a minimum amount of materials. Pipes or hoses will be needed, the coolant will be in them. It can be antifreeze, kerosene, gasoline, and generally non-freezing substances.

A hydraulic turbine or any other device that could turn mechanical energy into electrical energy.
You can make a water hammer installation and then connect a membrane with a solenoid and a permanent magnet to it. The membrane will vibrate, vibrations will be transmitted to the core of the solenoid and thus induction currents will occur.
The idea of ​​a simple heat pump. Alternative for the winter


The circuit consists of two coils, one upper and one lower. It can be radiators of batteries, various snakes, however you can make a coil yourself from a pipe or hose.

The lower radiator will be located underground at great depths, best if it is a well with spring water. As you know, the underground temperature is always positive, even in winter. If you look at the springs with spring water, then it does not freeze even on the surface.



An artist out of me, but I think it will be clear)

The upper radiator will be located on the surface of the earth and it is best that a sun dome be placed above it.

Both radiators are interconnected by pipes in a circle.

How does it all work? As soon as winter comes and the temperature drops below -1, fluid begins to circulate in the system. Below it will heat up, expand, become lighter and move up. This is a free energy that can be "removed".
About -1, I said figuratively, formally, if there is +5 underground, and +4 on the surface, the system will also work.Of course, the stronger the difference in temperature, the more energy will be released.

Such systems can be made many or one large. This can significantly reduce heating costs. I will try to assemble such a structure in the village in the spring.

the water will certainly freeze))

For assembly, you need a minimum amount of materials. Pipes or hoses will be needed, the coolant will be in them. It can be antifreeze, kerosene, gasoline, in general non freezing substances[u] [/ u].
it will not circulate) I know that I am writing. At work, I have 5 wells of 80 meters each. Water from the well is always +16. On the street now -4. So, this water is in containers of 40 tons, but if the outlet or inlet pipe is not insulated, the water freezes in the pipe. By your analogy, with such a temperature difference, water from the well or from the barrel should circulate, but this does not happen. If you want cheaper energy, look towards rotary stirling. A bunch of patents. You can heat it with alcohol. Or, for example. Instead of water, acetone, alcohol, etc. can be used.

here came another idea.
To "remove" energy, you can use a conventional water meter)) The liquid circulates, the meter spins ...
Sea projects. and amateur from cans and at a higher level with turning and milling. And now it’s impossible not to lay out your own homemade products now. I'm still doing a low ampere electrolyzer. In the phase of lapping tubes is. And a more beautiful build. I want to try to heat water with a hydrogen flame and count the numbers.

Yes, and a discussion of all sorts of different things to save fuel and generate energy will result in empty chatter like "this is not possible", for this a lot of sites are like "charge".

here for this respect!)) Yes, there are all conditions for the operation of the Stirling engine. Only it can be not gas, but hydraulic. And in order for such an engine to work more efficiently, it is necessary to use liquids with a maximum degree of expansion when heated.

Of course, ideally, this is mercury, but by itself, in fact, no one will use it. A great alternative is alcohol. There will be time, I sketch a little sketch.

Here there is already energy will be dear mom and higher efficiency))

By the way, I already laid out one Stirling project, see that you do not get the same one.
those. you propose to make a stirling engine. Consider the heat loss in your pipe. such a volume is likely not to rise hot. if only at the upper end to create a vacuum pressure.

By the way, at the expense of stirling. I began to translate an article about a stirling engine combined with an electric generator, but the rules of the site have changed. So, you can set the hot side on the solar concentrator in focus, either directly, or connect with a heat pipe. On the Internet, the sea of ​​designs of heat pipes "knee" manufacture

no, I made a mistake with the joules, there are kilograms, which means it is 1500 * 9.8 * 10 = 147000 = 147 KILO

147kJ = 40.8 Watt / hour. That’s how much energy there will be when the pipe cross section is 100 cm2, its height is 10 meters and the temperature difference is 20 degrees C. But this is all in the eye)) I'm not friends with mathematics))

In the refrigerator, a completely different principle, there the pressure decreases due to a decrease in gas pressure. And then the expansion / contraction is a consequence of the thermal effect.
It’s better to upload the file to disk (Yandex, Google) and insert the link - in the comments this does not work correctly. Sorry for the offtopic.
Very interesting. You know in refrigeration there is such a thing as a heterosis loop. Without observing the relationship of temperatures and pressures, nothing will work. That is why air conditioners write a range of operating temperatures. What is in cooling mode, what is in heating mode. All this must be calculated. And the second thing I wanted to write. In 1975, a patent was issued for an invention in the field of refrigeration. In the application, it is indicated that with proper calculations, the refrigerator can work without a compressor, i.e. without additional supply energy for cooling. According to this patent, it seems like even refrigerators began to be made, but they were not allowed into the series. here is the patent itself
[attachment = 205: patent]
Nothing, in principle, prevents you from making a heat pump using the same principle. Find a refrigeration engineer with relevant knowledge. And let him calculate.

Well, all this can be calculated. You need to know how the density of a substance depends on temperature.

For example, water at 0 degrees has a density of 999.8 A at +20, a density of 998.3

That is, a water column 1 meter high will exert a pressure of 99.8 grams / cm2
A column of water at a temperature of 20 degrees will exert a pressure of 98.3 grams / cm2

Now suppose that the height of the pipes is 10 meters, in this case we have an imbalance in weight equal to 15 grams / cm2.
With a pipe cross section of 100 cm2, we have an imbalance of 1,500 grams, 1.5 kilos. This is the energy that must then be converted. This is equivalent to the fact that the load of 1.5 kg falls from a height of 10 meters down.

A = 1.5 * 9.8 * 10 = 147 J. So?)) Well, this by itself is just an example. Most likely I'm wrong.

Much more depends on the speed of the coils, on the efficiency of heating and cooling. In any case, the energy is free ...
Such a geothermal system can also be used for heating, but it's not so simple - you need specialized equipment, because in fact it is a refrigerator only for a turn.

At the expense of energy production - the only question is - how effective is such a system?

there is still such a moment, the longer the connecting pipes are, the more active the circulation will be. It is very important. It is the height of the water column that will play a key role.
