Abstract

The pump of energy of pressure's temperature's difference uses the difference which exists naturally inside various extensive aqueous systems in combination with the temperature's difference which can be created by artificial means more than this which exists naturally and in addition the solar radiation or any other natural or artificial source which can give heat in order to produce electric energy. The blades bearing shaft (5) which is situated inside the cylinder (2) is supported on the floating platform (1) on which it is based the generator (8) which is put to movement by the blades bearing shaft (5) which is put to movement by the upward current of water which hits on the blades (6) which is created by the heating of the water of the aqueous system which there is at the lower part of the cylinder (2) by the heat transfer coil (14) and the bank of solar collectors (19) which are two of the parts of a closed circulation system of a suitable liquid.

Description

Pump of energy of pressure's temperature's difference

The invention refers to the pumping and exploitation of the energy which there is diffused in the environment as in extensive aqueous systems in the form of the gradient of temperature , in solar radiation , to natural warm springs and to every kind of natural or artificial sources.

Until today , systems are used which pump the diffused energy which exists in the air of the atmosphere with the form of the gradient of temperature but it isn't this energy their main target.

Basically target to the exploitation of the solar energy and for that purpose use high differences of temperature in order to obtain satisfactory efficiency of operation.

Also, they are installed on the ground and have great height in the air which make difficult their stabilization against several weather conditions .

To operate this systems is necessary the difference of pressure which exists at different altitudes in the air of the atmosphere .

The difference of the pressure in the air is very less than the difference of pressure which exists in the water of an extensive aqueous system for that reason the amount of diffused energy which exists in the air in the form of the gradient of temperature which in the end transformed into useful energy through these systems is small . Because of their enormous size confront problems of static stability while necessarily they must use focalization systems of the solar radiation towards the heating tower in order to be created the upward current of air which in the end exploit for the production of movement of a blades bearing shaft .

To operate with satisfactory rate of efficiency they must necessarily use high differences of temperature again , so , these can not use mild heating which is the more easily found in nature such as warm water from natural warm springs and from solar collectors which are simple and easy to handle from constructive view elements for the collection of solar energy . With the use of this pump of energy of pressure's temperature's difference are solved all the above mentioned problems.

So we can have efficient pumping of energy from the environment using even and mild heating without to be excluded the using of high difference of temperature if this is desirable and under conditions of better static stability and without focalization systems without them to be excluded if this is desirable.

The pump of energy of pressure's temperature's difference use great differences of pressure to reach efficient operation at medium difference of temperature and also great differences of temperature into extensive aqueous natural or artificial systems.

Because of its special construction with the floats along the cylinder which surrounds and supports the blades bearing shaft and bindings that the cylinder has with weights at the bottom plus its support on floating platform plus the bindings of the floating platform at weights at the bottom from binding's extensions which it bears it is succeeded effectual supporting of the whole installation and satisfactory static safety .

Moreover , the special shape of the floating platform at the place where it is joined with the upper part of the cylinder allows the free flow of water which comes from the upward current which is created in the cylinder through heating by a heat transfer coil which carries at the lower part of the cylinder and under the blades bearing shaft heat which is absorbed through the solar collectors or supplied with any other way to a closed circulation system of suitable liquid which may be the water .

Also with the help of tanks for the storage of hot water or devices for the storage of heat it may operate during the day and night feeding unfailing the consumption .

The main advance of the invention is that it can work at a variety of temperature's differences from medium differences which are quite available in nature and could be reached easily with artificial means until however great but suitable for the constant operation of a thermal machine are possible to be reached with today's technological means .

This is happen because it exploits simultaneously the temperature's difference which exists naturally or could be created through artificial means between the upper surface of an extensive aqueous natural or artificial system (as e.g. sea , lake , artificial lake etc.) and a surface which is at a definite depth which may to be a little higher from the bottom or even higher , according to the constructive demands as also and the pressure's difference between the two surfaces up and down that it is very greater than the corresponding pressure in the air at the corresponding altitude . So it is advantageous against analogous based on land systems which operate in the air which necessarily must use great temperature's differences in order to succeed the corresponding moving upward flow of air that brings about the same results as regards the final production of energy .

Also , the statics of system characterized by greater stabilization and constancy according to the way of supporting inside the water using the floating platform the annexed floats on the cylinder and the weights at the bottom from where it is bound the whole installation against the supporting which has an overland system with great height in the air .

It can also operate unfailingly all day and night . A way to accomplish this invention is described in the following with reference to drawings which show the qualitative characteristics and illustrate a particular realization of the invention as an example without it to consist any restriction .

The figure 1 shows a vertical section of the construction.

The figure 2 shows the upper view of the floating platform without to be included some constitutive parts.

The figure 3 shows the cylinder.

The figure 4 shows the floating platform and the cylinder before their assembly.

The figure 5 shows the mechanism of supporting of the blades bearing shaft where the figure 5A shows this mechanism while figure 5B how this mechanism must be at positions between on this blades bearing shaft .

The figure 6 shows the upper view of the supporting mechanism of the blades bearing shaft and it is explanation of the figure 5 where the figure 6A refers to figure 5A and figure 6B refers to figure 5B .

These drawings refer only to qualitative characteristics of invention and not to quantitative ones which at any time come up the particular constructive study according to the case . Now regarding figure 1 , we see that the installation which has to do with the realization of the pump of energy of pressure's temperature's difference consists of a set of constitutive parts two of them are the floating platform (1) and the generator (8) which is based on mount (7) which is fixed on the floating platform (1).

The generator (8) has joined its rotor with the vertical blades bearing shaft (5) which is supported at the conical scrolling bearing (24) which is embedded and fixed on the supporting base (21) which is supported at the cylinder (2) through the shank (20) and the extensions (23).

All that together consist the supporting mechanism (35) of the blades bearing shaft (5) .

The blades (6) of propellers are along the blades bearing shaft (5) . The cylinder (2) is clothed by thermal insulating material which we call cylinder's insulation (3) while outside the cylinder there are the floats (4) which are fixed on the cylinder (2) .

Both the floating platform and the cylinder have binding's points (16) from which the whole installation is bound on at weights (15) which there are at the bottom of the aqueous system.

There is no need the number of weights to be two as it appears on the figure it suffices their number to be adequate and they to be suitably situated .

Besides all that on the figure it appears a closed circulation system of a suitable liquid which for example can be the water .

This closed circulation system of suitable liquid consists from the pump (10) which is based on the mount of pump (9) on the platform (1) which pump (10) is clothed by waterproof thermal insulating material which we call insulation of pump (12) .

Also it includes the pipes (17) which are also clothed by waterproof thermal insulating material which we call the insulation of pipes (18) , the bank of solar collectors (19) which are based on the mount of solar collectors (22) and the heat transfer coil (14).

All that together in cooperation carry the heat at the lower part of the cylinder (2) where comes it in the cold water from the extensive aqueous system .

And finally there are the extensions of binding (11) which can extent to sufficiently larger stretch from this which is occupied by the platform (1) so as to be succeeded as much as possible more constant binding of the installation through the wire ropes (13) at the weights (15) which there are on the bottom which also have points of binding (16) the same as the extensions of binding (11) have their own points of binding (16) .

Also , it is showed the surface level (33) of the aqueous system and the bottom (34) of the aqueous system .

As regards the conical scrolling bearing (24) in the figure it appears only its position and it is not drawn its section . The same is happen for the waterproofing mechanism (36) , the pump (10) , the generator (8) and the blades (6) which all that are shown schematically while the supporting mechanism (35) is shown analytically on the figures 5A and 6A while here have not drawn the screws (25) which are shown in these figures.

Also it appears the electric power distribution mechanism (29) , which includes the function starting switch and stores in batteries an amount of the electric energy and distribute the power which is produced by the generator (8) at the motor (27) through the feeding terminals (30) while the terminals of final power (32) go to the consumption .

At the power reception terminals (31) is plugged in the output of the generator (8) .

Also we see the supporting extensions (11) of the floating platform (1) and the points of binding (16).

In this figure it is not included the supporting mount (7) , the generator (8) and whichever contains the cylinder (2) that however appeared in the figure 1 , as well as , it is not included the mount (9) of the pump (10) .

For waterproofing mechanism (36) it is shown schematically its position without it to be drawn analytically .

In the figure 5B we see the version which is suitable for the supporting of the blades bearing shaft (5) at points between its upper and lower end until the point which reaches at the generator (8) where it is necessary and reinforce its supporting against collateral vibrations . Here we see a cylindrical scrolling bearing (24B) its supporting base

As regards the cylindrical scrolling bearing (24B) in the figure it is shown simply its position and it is not drawn its section .

While the waterproofing mechanism (36) it is not drawn at all .

The fact that the above constitutive elements are not drawn in the various partial figures it doesn't mean that they don't exist but this is done for convenience of the drawing . The whole installation of the pump of energy of pressure's temperature's difference results from the combination all of the elements that are showed in the drawings and mentioned in the description .

The way of operation of the pump of energy of pressure's temperature's difference and according to the figures 1,2,3,4,5,6 is the following :

The closed circulation system of suitable liquid which consists from the bank of solar collectors (19) , the circulation pump (10) of suitable liquid , the heat transfer coil (14) and the thermal insulated pipes (17) absorbs the solar radiation in the form of heat and transport it at the heat transfer coil (14) with the help of the circulation pump (10) of suitable liquid through the thermal insulated pipes (17) .

The heat transfer coil (14) now heats the water in the lower part of the cylinder (2) .

So , it is created an upward current which moves the blades bearing shaft (5) which in turn rotates the rotor of the generator (8) which in turn produces the electric current .

While the warm water goes upwards in the cylinder (2) with the upward current , cold water from the lower part of the cylinder (2) get it in and in turn is heated by the heat transfer coil (14) .

The warm water while goes in through the cylinder (2) together with the upward current moves the blades bearing shaft (5) while in the upper part of the cylinder goes out in the surface level (33) of the aqueous system from the of special shape opening (39) of the cylinder (2) at the point where it is joined with the of special shape floating platform .

The shape of the cylinder (2) on its upper part is such so that to be compatible with the special shape of the platform (1) for the flow of the water of the upward current to be unhindered from the cylinder to the surface of the aqueous system .

The special shape of the floating platform (1) and of the upper part of the cylinder (2) it is ought to the fact that must there is the channel (38) to flow the water of the upward current from the cylinder (2) towards the surface level (33) of the extensive aqueous system but the number of these channels there is no need to be one they could be more but it is recommended one or two channels.

As regards now the bank of solar collectors (19) for this there is no need to situated entirely on the floating platform (1) or on a floating little island near it . It could has installed on the land so that to have big size and less cost and the produced hot water to be transported with suitably thermal insulated pipes at the installation of the pump of energy of pressure's temperature's difference which is situated in the extensive aqueous system . In any case that the hot water comes from installations which are situated on the land the closed circulation system of suitable liquid is recommended not to include the bank of solar collectors but in the position of the bank on the floating platform to exist a heat exchanger which will be transferring the heat from the hot water of the pipes which are come from the land to the closed circulation system of suitable liquid .

Also , the hot water from the solar collectors which are situated on the ground could easily be stored at great amounts in thermal insulated tanks and be used again during the night when there will be no solar radiation so that the whole installation to operate unfailingly independently if it is day or night , all round the clock . Also , instead of the solar collectors alternatively or complementarily it is possible to be used whichever way or natural or artificial means which could give hot water of a temperature higher than the temperature which prevail in the extensive aqueous system at the level where the heat transfer coil (14) of the pump of energy of pressure's temperature's difference is situated .

For example , water from natural thermal springs or hot water which is produced using heat storage devices to which it is possible to be used and the method of focalization of solar radiation by mirrors in order the working substance which they use , namely the stuff which absorbs and stores the heat to absorb and store great amounts of heat .

And finally , the pump of energy of pressure's temperature's difference could operate consuming a fuel or using electric energy which it will be replenishing in the end to heat the water of the closed system because the pump of energy of pressure's temperature's difference pumps also energy directly from the aqueous system and if this energy which is pumped is greater than the energy which is spent the pump of energy of pressure's temperature's difference operates gainfully and in that case .

However in any case the quantitative characteristics of the installation of the pump of energy of pressure's temperature's difference must be chosen suitably so that it to operate gainfully .

In all cases where in the description it is mentioned that it is used thermal insulating material this is also must be and waterproof . The heat transfer coil is metallic in order to have good thermal conductivity and from suitable material which resists the corrosion in the wet environment where it will be according to the case .
