Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat pump device using metal hydrides.

It is known that certain metals and alloys exothermically absorb hydrogen to form metal hydrides, and that these metal hydrides reversibly and endothermically release hydrogen. Various types of pump devices have been proposed that utilize the characteristics of metal hydrides.

Conventionally, in principle, such heat pump devices fill metal hydrides into two closed containers that also serve as heat exchangers, cause one metal hydride to endothermically release wood leaves, and then transfer this hydrogen to the other metal hydride. The structure is such that a cold or thermal output is obtained by exothermically occluding the hydride, and the above process is performed alternately on the metal hydride.

That is, FIG. 1 shows how to obtain cold output or hot output in a conventional heat pump device. A second metal hydride Ms having a high equilibrium decomposition EEP at the same temperature in the operating temperature range is shown, showing a J1 seed cycle and heating the metal hydride MtH in a high temperature gas to release hydrogen (point A).
While keeping H at intermediate temperature T (<'I'H), its equilibrium decomposition pressure is made smaller than Min at temperature T, creating a pressure difference between it and MIH, and the hydrogen released by MIH is Using this differential pressure, MsH is exothermically occluded (point B). Next, keep MIH at 1 degree 'l'M, keep M back at low temperature TL (<'I'M), and set the equilibrium decomposition pressure of M and H at temperature TTJ to that of Min at temperature 'I'M. is made larger than that, hydrogen is endothermically released from Man (point D), and this water volume is exothermically stored in MIH (point C). M.I.H.
One cycle is completed by heating M and H again to temperature #IIH and keeping M and H at temperature TM. In this cycle, point A
G, - By applying driving energy from a driving heat source, connecting points B and C to a heat exchanger using air or water as a heating medium, and connecting point D to a cooling medium such as cold water, this cooling medium is Cooling output can be obtained from.

On the other hand, by connecting the point to a driving heat source and connecting the point to a heating medium such as water, it is possible to obtain thermal output from the heating medium at points 1 and 0.

Figure 2 shows a conventional Type 2 cycle, in which thermal output is obtained from point C by connecting a point and a point to a driving heat source, and the thermal output at point 0 B is normally dissipated outside the system.

Therefore, in order to perform the above-mentioned cycle using heat exchanger pairs filled with MIH and MsH and obtain continuous output, it is necessary to assemble two or more heat exchanger pairs, each of which is connected to the other. As a result, part of the reaction heat of the metal hydride is always consumed in heating and cooling the heat exchanger itself during the above cycle, so if the coefficient of performance is small, In addition, there is a problem that the device configuration becomes complicated and large.

FIG. 3 shows a dual effect heat pump device.

The pressure-resistant sealed container 1 has a high pressure chamber 4 and a low pressure chamber 5 at intervals 2 and 3.
and intermediate pressure chamber 6 in this order.

Between the high temperature roll 11 of temperature Tl placed in the high pressure chamber and the medium temperature roll 13 of temperature Tsl placed in the low pressure
A first tape 7 in the form of a rotating belt carrying metal hydride MIH of It is driven to run continuously in the direction. Each roll is thermally connected to a heat exchanger in a continuous chamber to maintain a predetermined temperature (not shown). The first tape 7 is brought into contact with the heat exchange roll 20 in the low pressure chamber, and the first tape 7 heated in the high pressure chamber enters the low pressure chamber and is precooled by the heat exchange roll 20, then transferred to a medium temperature roll 13
reach. First cheese 1 cooled by medium temperature roll 13
7 enters the high pressure chamber and is brought into one contact with the heat exchange roll 19. This heat exchange roll is 19til.

It is thermally connected to the heat exchange roll 20 by, for example, a heat pipe, and preheats the first tape 7.

The temperature in the hyperbaric chamber is different! ■ A medium temperature roll 12 is arranged,
Temperature placed in the low pressure chamber! The second low-temperature roll 14
The second tape 9 carrying the metal hydride MsH is wound in the same manner as described above, and is driven to run continuously in a fixed direction. 2nd tape 9 thermally connected heat exchange rolls 21
and 22 for preheating or precooling.

In the above, as shown in Fig. 4, MsH is the operating temperature range, (T1 absolute temperature) is the same temperature &: MIH
has a higher equilibrium decomposition pressure than MI at temperature 〒1
H has a higher equilibrium decomposition pressure than MsH at temperature 'l'lk, MmH at raw coal 〒4 has a higher equilibrium decomposition pressure than MIH at temperature T and 1, and? .

Each temperature is selected so that 〉tezk>〒sr>'I'+.

In this way, the first and second tape pairs carrying MIH and MAR, respectively, travel between the high pressure chamber and the low pressure chamber to perform the A-B→F→arm cycle, as will be described later. .

Similarly, another medium-temperature roll 15 having a temperature of Tsl is disposed in the low-pressure chamber, and a third tape 8 carrying MIH is driven to run between it and a medium-temperature roll 17 having a temperature of Tsj disposed in the medium-pressure chamber. The medium temperature roll 17 tiThe medium temperature roll 12
It is thermally connected by a heat pipe heat circuit 27, and as described later, heat generated when the second Qi 19 absorbs hydrogen in the high pressure chamber is transmitted to the medium temperature roll 17 in the medium pressure chamber.

In addition, the fourth tape 10 carrying the threshold rMan of the low temperature roll 16 of 1114°C placed in the low pressure chamber and the medium temperature roll 18 of 111Ik placed in the medium pressure chamber is only driven to run, and these tapes are Heat exchange rolls 23 and 2, respectively

The third and fourth tape pairs carrying mH are cycled 0-D-1f→1→0 as described below.

The operation of the above-mentioned device will first be described with reference to the type 1 cycle diagram shown in FIG. 4 in the case where a cold output is obtained. The temperature shown in Figure 4 is incorrect as explained above, so the temperature shown in Figure 4 is
The tape 7 of MxHa is placed in the high pressure chamber and heated by the heat exchange roll 11, which is a driving heat source, to a temperature Tl&: to release hydrogen at point A), and this hydrogen is maintained at a temperature Tlk in the high pressure chamber at the second tape 9. is occluded by MsH (point B). The amount of heat generated during this storage is transferred to the third
MIH of tape 8 is supplied. This is represented in FIG. 4 as heat transfer from point B to point C. After releasing the above hydrogen, the first tape 7#'i in the high pressure chamber enters the low pressure chamber and is cooled.Meanwhile, the second tape 9tj in the high pressure chamber after absorbing the above hydrogen. , enters the low pressure chamber,
Due to the pressure difference between the first tape 7 and the MIH equilibrium decomposition pressure, hydrogen is endothermically released at temperature T4. l), this hydrogen is occluded by the MIH of the first tape 7 (point F) 1
Due to the endothermic reaction of MIH at point I, heat exchange roll 1
4 obtains cold output at temperature No. 1. In addition, points! The reaction heat resulting in MIH is dissipated to the outside of the yarn by the heat exchange roll 13.

In this way, the MIHti of the first tape 7 moves back and forth between point M and point 7 according to FIG. In other words, this tape pair undergoes a cycle of B→1→A→M.

Next, as described above, the heat exchange roll 17H in the medium pressure chamber
M of the third team 18 receives heat from the heat circuit 27
IH at temperature 1!1. , to release hydrogen (point C), and this hydrogen is occluded by M and H of the fourth tape at a temperature of 〒$ in a medium pressure chamber (point D), and the heat of reaction at this time is It is radiated out of the yarn by the heat exchange roll 18. After the above hydrogen absorption, the fourth tape 10 it enters the low pressure chamber and the temperature is 〒
Due to the pressure difference between the equilibrium decomposition pressure of the MIH of the third tape 8 held at Ij, hydrogen is released endothermically. (point F)
. That is, the temperature of the heat exchange roll 16 is maintained at point 1, and the cold output is obtained at the temperature T4.

In this way, the third tape 8 companies (FIG. 2) move back and forth between points 0 and 1, and the fourth tape 10 moves back and forth between points 1 and 1, thereby absorbing and releasing hydrogen from each other. That is, this tape pair performs a cycle of 0→D-4'E→r→C.

In order to obtain the first type thermal output according to the first type cycle diagram shown in FIG. The heat of reaction accompanying hydrogen storage by MIH and MsII at point 1 is obtained as thermal output, and the required amount of heat for releasing hydrogen from the heat source at temperature T4 at point I is supplied to MIH and Man.

As described above, in the heat pump device of the present invention, using MIH of the first tape 7 and M and H of the second tape,
Due to the driving heat source at temperature T, Mu→B -1-4! →The cycle of the third team 18 is performed, and the amount of heat generated at point B of the above cycle is supplied to point 0 as a driving heat source, and the third team 18
C-D-'l- to 0MIH and MsH of fourth tape 10
The 7-0 cycle reduces the amount of energy required for operation and improves the coefficient of performance of the device.

In the heat pump device as described above, if sensible heat loss accompanying heating and cooling of the tape supporting the metal hydride itself is ignored, the coefficient of performance is calculated as follows.

Let Ml and jHs be the reaction heats associated with absorption and desorption of 14 liters of hydrogen in MiB and MSIl, respectively, and consider a case where 14 liters of hydrogen are absorbed and desorbed between the first tape and the second tape, respectively. In the cycle of M → B → 1-1 → M, the input of heat is ΔH1 at point M and JHs at point 1, and the output of heat is jH at point 1, and IH1'' at point 1. Assume that the amount of heat generated at point B''e is supplied to point C without any loss. So, C-4D
-41! It spills into the cycle of l-4A→C, and M at point C.
Since the hydrogen released by IH is H1/H, moles,

Since υ is given by (thermal output obtained by heating and heating/heating output at point A), -...(2).

In addition, according to the present invention, the low pressure chamber 5 can be divided into two pressure chambers at 911130. Therefore, heat exchange rolls 13 and 15 and heat exchange rolls 14 and 16 are
and can be set to different temperatures. Therefore, the heat exchange roll 13 is set at a temperature T6 as shown in FIG.
Temperature of heat exchange roll 14! set to 1, first chi 17
And the second tape 9 is subjected to the cycle of Mu → B-I → J → Mu Zeng, the third tape 8 and the fourth tape IO&-C

Figure S shows the company's triple effect type and one pump device, and Figure 6 is its type 1 cycle diagram. This device 4: Imperial Rule T is a sealed container 111a! The high pressure chamber 4, two medium pressure chambers 116m and 6b, and the low pressure chamber 5 are divided by 111H13 and H29. However, as is clear from comparing Fig. S with Fig. 3, the equipment company in Fig. 5 has a high pressure chamber 4 in the apparatus shown in Fig. 3, and the high pressure chamber 4 in Fig. S is replaced with an intermediate pressure chamber 6.
1, it is formed by setting the medium pressure chamber 6 in Ij3 &:iB to medium pressure gsb. In general, high-pressure chambers, medium-pressure chambers, and low-pressure chambers are distinguished only by the level of working hydrogen pressure of the metal element in the compartment, so the compartment with the highest working hydrogen pressure is the high-pressure room, and the compartment with the lowest is the high-pressure room. The chamber is called a low-pressure chamber, and the intermediate compartments are called the first intermediate-pressure chamber, the second intermediate-pressure chamber, etc. in descending order of the operating hydrogen pressure, and the device of the present invention is generally referred to as a high-pressure chamber. A pair of tapes carrying MIH and MsB, respectively, is run continuously between the low pressure chambers and between each intermediate pressure chamber and the low pressure chamber in the form of a rotating belt, hydrogen is transferred between the tape pairs in each compartment, and hydrogen is transferred between the high pressure chambers. The MlH and the MIH of the first medium pressure chamber are thermally connected, and the Ms of the first mountain main chamber is
H and the MtH in the second medium pressure chamber are thermally connected, and in this way, it can be used as a heat source for the hydrogen storage of MIH in the medium pressure chamber, accompanying the hydrogen storage of MmH in the previous high pressure chamber or medium pressure chamber. It utilizes heat generation, and hydrogen is transferred from MIH to MIH between each pair of tapes in the low pressure chamber.

Therefore, in the triple effect type device shown in FIG. 5, a fifth tape 44 carrying MIH is placed between the heat exchange roll 40 disposed in the high pressure chamber and the heat exchange roll 43 disposed in the low pressure chamber.
is run, a sixth tape 45 carrying MIH is run between a heat exchange roll 41 disposed in the high pressure chamber and a heat exchange roll 42 disposed in the low pressure chamber, and
A heat exchange roll 11 for MIH in the first intermediate chamber 6a is connected to the roll 41 that exchanges heat with the heat exchange roll 41 through a heat pipe or other suitable heat circuit 28.The heat exchange roll 12 and the heat exchange roll 17 are connected The configuration of the tapes between the first and second intermediate pressure chambers and the low pressure chambers, including the thermal circuit 27, is the same as described above.aS, the rolls for precooling and preheating each tape are not shown.

FIG. 6 is a type 1 cycle diagram showing the operation of the triple effect m device. The alphabets marked on each heat exchange roll in FIG. 5 correspond to each point in the cycle diagram in FIG. input, and causes MIH to release hydrogen at a temperature of 1lfll (point G
], this hydrogen is applied to M and III of the sixth tape 45 at a temperature of +
71. It is exothermically occluded by (point H). This heat is applied to the MIH of the first tape 7 in the first medium pressure chamber 6a&: by the thermal circuit 28, causing hydrogen to be released from the MIH (
Point Mun.

After the hydrogen release described above, Mll of the fifth tape 44 enters the low pressure chamber and reaches a temperature of T4. M of the sixth tape 45
mH is the temperature after entering the low pressure chamber after absorbing hydrogen as described above! M and Ill endothermically release hydrogen due to the pressure difference between the equilibrium decomposition pressures, and MIII absorbs this hydrogen exothermically (point F). The hydrogen movement of each tape pair running between the medium pressure chamber and the low pressure chamber of 2.
Comparing this figure with FIG. 4 reveals that they are completely equivalent. Therefore, the fifth and sixth tape pairs on the right side of this device are G
The cycle of →■→1g-F-G is performed, the first and second tape pair performs the cycle of A-B→E→F→mu, and the third and fourth tape pairs perform the cycle of C→D- A cycle of 1 → F → M is carried out, and in this way, the cold output can be obtained from point I, or it is turned on and then on! More thermal output can be obtained.

The coefficient of performance when obtaining cooling output with this triple effect type device is determined as follows.

As mentioned above, if the amount of hydrogen transferred from point G to point H is 1 mole, the amount of heat of IHL is generated at point H and this is given to point M, so the amount of hydrogen transferred from point A to AB is /jH1 mole. Therefore, at point B ()Ha/
IH1) lHs=ノUs''/IHl A heat quantity is generated, and this heat quantity is lost (if supplied) to point C by the thermal circuit 27, then the amount of hydrogen transferred from point C to point #'i (]US

Next, the fifth and sixth tapes G→■→I→1→Gf

and A-B-1→! by the second tape. → In the cycle of A, the amount of hydrogen transfer between points I and 1 is calculated as follows:
Since Hs / ΔH1 mole, the point xk - the cooling and heating output () / ΔHt) no Hm - 7Hs'' / ΔH1. Also, for the third and fourth tapes, 0 → D - 1 →! →C
In the cycle, the amount of hydrogen transferred between points 1 and 1 is no H, m/no H1fi mole as described above, so by invoking point I, ()1111''/1Hj) IHl = no H?/I
Obtain H- cold output.

Therefore, this coefficient of performance OOP1cm is also the coefficient of performance 00Pxhs when obtaining thermal output.
Input ノH into point G and get the thermal output at point G and F, so similarly = 1 +0OPxcs --(4)
It is.

Although not shown, it is possible to divide the low-pressure chamber into sections and place each pair of tapes to be cycled at different temperatures (thereby, it is possible to obtain cold or heat output at different temperatures. This is the same as described above. .

Next, the case where heating or cooling output is obtained by the second type cycle using the apparatus shown in FIG. 9J3 will be explained with reference to the 182M cycle diagram shown in FIG. 137. 1] Comparing Figure 1F7 with Figure 4, it is clear that the input of driving energy to point M, hydrogen movement from point A to point B, heat transfer from point B to point C, and from point C to The hydrogen transfer to point 1 is equivalent in both cycles, and in the cycle diagram of Figure 7, from point 1 to point ! Hydrogen transfer to point 1 occurs on the high temperature and high pressure side, similar to the case in Figure 4, and this hydrogen transfer is used to
Get thermal output from. Therefore, when carrying out the cycle shown in Fig. 7, the temperature is set at a temperature different from that in the case of the Type 1 cycle, as shown in Fig. 7, by the letters added for each heat exchange roll in Fig. 3. , point I
A heat exchange roll having a temperature of point r and a temperature of point r is placed in a high pressure chamber 5t, a heat exchange roll having a temperature of point m and point B is placed in a medium pressure chamber 4',
Furthermore, heat exchange rolls having temperatures at points 0 and D may be disposed in the low pressure chamber 6'.

The coefficient of performance of this device is determined as follows. 1st

NoEx)NoH1=NoHl.

Therefore, there are several companies that perform well when obtaining thermal output.

Similarly, the coefficient of performance when obtaining cooling output is It is.

In the case of this type 2 cycle, two or more intermediate pressure chambers are provided, and the heat generated when M and H absorb hydrogen in the higher pressure chamber is successively removed from the lower pressure chamber &l.
by providing it as a heat source to release hydrogen.
It will be clear that more than triple effect devices can be constructed.

As described above, according to the carbon pump device of the present invention, a pair of tapes carrying a metal hydride having different equilibrium decomposition pressure characteristics is run at a constant speed between the eight chambers where the operating pressure is different. Because of this, there is no heat loss consumed in heating and cooling the metal hydride-filled heat exchanger itself as in conventional equipment, and a stable and essentially continuous output can be obtained. . Furthermore, the heat generated when the metal hydride absorbs hydrogen in the input tape pair is used as driving energy for another tape pair, and if necessary, the heat generated in this tape pair is used to drive another tape pair. Since it is a multiple effect type used as driving energy for
The coefficient of performance of the device increases significantly.
