The most commonly used absorption refrigerator at present is a water-lithium bromide absorption refrigerator. Such an absorption refrigerator has a part that operates under high vacuum, and the internal pressure of the evaporator is 5.
~10 (mmHg.abs), in the condenser its internal pressure is
It is 50-70 (mmHg.abs). Therefore, air may leak from the outside into parts that operate under high vacuum, or hydrogen gas may be generated internally due to corrosion of the metal that makes up the parts or the action of corrosion inhibitors, resulting in non-condensable conditions. When gas accumulates, even a small amount of gas accumulates, it has a large effect on the performance of the refrigerator. Let us further examine the relationship between the accumulation of noncondensable gas and the performance of the refrigerator. In an actual refrigerator, if the hydrogen partial pressure outside the machine is virtually zero, the hydrogen partial pressure inside the machine will depend on the degree of hydrogen gas generation, but even a few (mmHg) will greatly affect the refrigeration performance. Are known. For example, the pressure in the evaporator of an absorption refrigerator is 7.01 (mmHg.abs)
At this time, the refrigerant water will evaporate at 6 (℃), but if hydrogen gas is generated inside the machine and the hydrogen partial pressure becomes 3 (mmHg.abs), the pressure in the evaporator will increase to 10.01 (mmHg.abs). ) and the refrigerant is 11 (℃)
This results in evaporation and the refrigerating capacity is greatly reduced. In other words, it can be seen that the refrigerating capacity decreases in proportion to the amount of hydrogen gas generated.
そこで、従来は、真空ポンプを設置し、又はパ
ラジウムセルを設置することにより、これら不凝
縮性ガスを除去して冷凍能力の低下を抑えてき
た。 Therefore, in the past, these non-condensable gases were removed by installing a vacuum pump or a palladium cell to suppress the decrease in refrigerating capacity.

However, installing a vacuum pump
In addition to the problem of the high cost of the pump itself, there is also the problem of increasing the external dimensions and weight of the refrigerator. In addition, there is also the problem of having to maintain and inspect the vacuum pump.

的に水素を除去した場合に、機内外の水素分圧差
が極めて小さくなると、第６図からもわかるよう
に、水素拡散速度が極めて小さくなる。 As can be seen from Figure 6, installing a palladium cell requires heating the palladium itself to over 300 degrees Celsius in order to release the non-condensable hydrogen gas inside the refrigerator outside the machine at a practical rate. There is a problem that there is. In addition, when installing a palladium cell, in order to increase the amount of hydrogen gas permeating from inside the refrigerator to the outside, the contact area between palladium metal and hydrogen gas must be made as large as possible, and mechanical strength must be There is a problem in that the amount of precious metal palladium used increases, such as the need to make the board thick enough to maintain the same. Furthermore, Figure 6 shows the hydrogen diffusion rate in palladium, and it can be seen that the diffusion rate of hydrogen in palladium is governed by the square root of the difference between the hydrogen partial pressure inside the refrigerator and the hydrogen partial pressure outside the refrigerator. I understand. When hydrogen is continuously removed outside the machine, if the hydrogen partial pressure difference between the inside and outside of the machine becomes extremely small, the hydrogen diffusion rate becomes extremely small, as can be seen from FIG.

をもつ水素吸蔵合金を選択した。 As can be understood from this figure, there is a pressure plateau region in which the pressure does not increase even if the amount of hydrogen storage increases in the hydrogen storage alloy, and the lower the temperature, the wider the pressure plateau width becomes. It has a wide range of storage capacity. FIG. 4 shows the temperature dependence of the plateau pressure of hydrogen absorption and dissociation for various representative hydrogen storage alloys. As mentioned above, the hydrogen partial pressure of the non-condensable hydrogen gas in the absorption refrigerator is as low as several mmHg in absolute terms, so the plateau pressure of hydrogen storage and dissociation in the hydrogen storage alloy must be kept as low as possible. In other words, it was found that unless the pressure is below the above-mentioned number (mmHg), a sufficient amount of hydrogen storage cannot be expected and it cannot be put to practical use.
Therefore, in order to store sufficient non-condensable hydrogen gas without heating the hydrogen storage alloy, we have developed a hydrogen storage alloy that is capable of storing sufficient non-condensable hydrogen gas even under the temperature and pressure conditions during cooling operation in the summer, when hydrogen gas is likely to be generated and hydrogen gas has a significant impact on operation. A hydrogen storage alloy that exhibits the following characteristics was selected.
Here, for the temperature and pressure conditions, we selected a hydrogen storage alloy that has a plateau pressure of about 0.001 (atm) (0.76 mmHg) in absolute pressure when the outside air temperature is 30 (℃) during cooling operation. .

る。 As shown in Figure 5, the alloys used in this example are Ti-Fe alloy, Ti-Co alloy, Zr
(AxB 1-x ) 2 [(A: V, Cr, Mn), (B: Fe, Co),
(X=0-1)] type alloy was used. This is a typical hydrogen storage alloy that satisfies the aforementioned operating conditions. This alloy was selected because it is possible to shift the pressure-temperature characteristics to a certain extent as desired by changing the alloy composition or adding a small amount of different metals. . Further, the hydrogen storage capacity of these alloys is about 1% of the weight of the alloy, and 1 (g) of the alloy can store approximately 100 (ml) of hydrogen. The reaction rate between the alloy and hydrogen is high, and the pressure is extremely low when used in an absorption refrigerator, but in the case of an absorption refrigerator, such a high reaction rate is not originally required, so it is fully practical. Furthermore, this type of hydrogen storage alloy can be absorbed by water vapor, oxygen, nitrogen, etc.
Although it depends on the type of alloy, it may become poisoned and lose its hydrogen storage ability. For this reason, a protective film was provided on the surface of the alloy to allow only hydrogen to pass through. In this way, it is also possible to prevent the alloy from becoming pulverized. When this hydrogen storage alloy is used in an absorption refrigerator, the alloy is poisoned by the water vapor of the refrigerant that is the refrigeration composition, and loses its hydrogen storage ability. Therefore, an alloy coating was applied. One example of forming a film on this type of alloy is to plate the surface of the hydrogen storage alloy with Cu, Ni, etc. Oguro et al. applied electroless copper plating to LaNi5 powder as a battery material, and reported that its properties did not change even after repeatedly absorbing and desorbing hydrogen in an aqueous solution (Keisuke Oguro et al. Chemistry”, 53, No. 9 (1985), No.
722 pages). By forming a metal film on the surface of the hydrogen storage alloy, it is possible to block poisonous gases such as water vapor and allow only hydrogen gas to pass through, making it suitable for practical use in absorption refrigerators. Furthermore, similar effects can be expected even if the hydrogen storage alloy is coated with a resin or the like that has a low permeability for gases such as water vapor and oxygen, and a large permeability for hydrogen.
