液中のオクチルアルコールの量が次第に減ってしまう。(b) Prior Art In the above-mentioned absorption refrigerator, octyl alcohol has the effect of increasing the refrigerant absorption ability of the absorption liquid, so there is an advantage that the refrigerating ability can be improved. However, the octyl alcohol dissolved in the absorption liquid is completely heated and vaporized in the generator, and the vaporized octyl alcohol passes through the condenser together with the refrigerant until it liquefies and reaches the evaporator, where it reaches the upper layer of the liquid in the refrigerant reservoir. Since the octyl alcohol liquid floats and stagnates in the absorption liquid, if the absorption refrigerator is operated for a long period of time, the amount of octyl alcohol in the absorption liquid will gradually decrease.

発器の気相部に滞留するという問題点もある。(c) Problems to be Solved by the Invention In the conventional absorption refrigerator described above, it is possible to reduce the amount of octyl alcohol in the refrigerant reservoir by vaporizing it, but the amount of octyl alcohol in the refrigerant reservoir can be reduced. Since the refrigerant liquid is also vaporized, it is necessary to use an absorber to absorb the refrigerant that is not used for the refrigeration action, which causes a problem of loss. In addition, normally, an amount of octyl alcohol is added to the absorption liquid in the absorber that exceeds its solubility in the absorption liquid, so the octyl alcohol vaporized in the evaporator is not sufficiently dissolved in the absorption liquid in the absorber and the octyl alcohol is added to the absorption liquid in the absorber. There is also the problem that it remains in the gas phase.

The adsorbent (X) is not limited to PP fiber felt or cloth, but also materials that have an affinity for octyl alcohol, such as cotton, valve fiber, wood fiber, or other vegetable fiber cloth, inorganic fiber sheets, or urethane foam.

The flexible tube (T) made of, for example, Teflon is fitted, and the liquid suction conduit (W) is formed by this tube and the pipe (BP). Note that the flexible tube (T) and the float (F) may be made of materials other than Teflon as long as they are not susceptible to absorption by an absorbing liquid such as an aqueous lithium bromide solution.

It goes without saying that the opening may be opened above the cooler (28) or the like.

発器(6)の冷媒液溜めに滞留することも殆んどない。In an absorption refrigerator or absorption heat pump (hereinafter referred to as this machine) with such a configuration, a flexible tube (T
) is the solution reservoir (35) by the action of the float (F).
Since the solution reservoir (35) is located near the liquid level, during operation of the machine that operates the absorption pump (PA), the solution reservoir (35)
The aspirator of the dilute absorption liquid (FA) discharges the octyl alcohol floating in the top layer of the liquid using the pump (FA).
By the ejector action at A), it is sucked into this aspirator, joins with the concentrated absorption liquid in the pipe (22), and is distributed to the cooler (28) of the absorber (7). In addition, the octyl alcohol floating in the solution reservoir (35) of the absorber (7) hardly flows to the generators (1) and (3), so it boils together with the absorption liquid in these generators and cools the refrigerant. There is almost no chance of the refrigerant getting mixed into the refrigerant, and there is also almost no stagnation in the refrigerant reservoirs of the condenser (4) or evaporator (6).

本機の起動時の立ち上がり性能などに弊害を及ぼすこと
も殆んどない。Therefore, most of the octyl alcohol injected into the absorber (7) is used to enhance the refrigerant absorption capacity of the absorption liquid, which is useful for improving the capacity of the machine. In addition, since the stagnation of octyl alcohol in the solution reservoir (35) is also prevented, it is also useful for maintaining the sustainability of the performance improvement of the machine. In addition, since a large amount of octyl alcohol adheres to the heat exchanger (27) of the evaporator (6) and hardly interferes with wetting of the refrigerant liquid, the evaporation effect of the evaporator (6) and the There is almost no adverse effect on startup performance at startup.

ため、オクチルアルコールの溶液溜め(35)での滞留
は確実に防止される。During operation of this machine, even if the liquid level in the solution reservoir (35) moves up and down, the opening of the liquid suction pipe (Ken) will remain at the liquid level due to the action of the float (F) and flexible tube (T). Since it moves up and down at the same time, stagnation of octyl alcohol in the solution reservoir (35) is reliably prevented.

止される。In this machine, the octyl alcohol dissolved in the absorption liquid of the absorber (7) reaches the refrigerant reservoir (36) of the evaporator (6) via the high temperature generator (1) and the condenser (4). When the refrigerant begins to float on the surface of the refrigerant, the adsorbent (X) adsorbs octyl alcohol on its outer surface and diffuses it into the interior. The octyl alcohol that has moved upward from the point of contact with the adsorbent and has moved to the top end of the adsorbent is entrained in the flowing refrigerant liquid by the siphon function of the inverted U-shaped pipe (U) and is then transferred to the absorber (7). Solution reservoir (35)
fall to. In addition, this machine uses PP fibers (polypropylene fibers) that have a strong affinity for octyl alcohol as the adsorbent (X), so the so-called capillary action of these PP fibers promotes the movement of octyl alcohol. The lactyl alcohol in the refrigerant reservoir (36) quickly flows into the solution reservoir (35). As a result, stagnation of octyl alcohol in the refrigerant reservoir (36) is effectively prevented.

用換言すれば冷凍〔ヒートポンプ〕能力向上作用を長期
間持続できる。In this way, this machine is different from a conventional absorption refrigerator in which the octyl alcohol dissolved in the absorption liquid gradually accumulates in the refrigerant reservoir of the evaporator, while the amount of octyl alcohol sprayed into the absorber cooler gradually decreases. Unlike an [absorption heat pump], the octyl alcohol floating in the refrigerant reservoir (36) is returned to the absorption liquid side to prevent a decrease in the amount of octyl alcohol that can be sprayed into the cooler (28). In other words, the function of improving the capacity of the absorber (7) can be maintained for a long period of time.

部近くまで配備されているので、本機の運転中に冷媒液
溜め(36)の液面が上下動してもこの液面に浮遊して
いるオクチルアルコールの吸着作用に支障を来たすこと
はない。In addition, since the adsorbent (X) is arranged from the top of the refrigerant reservoir (36) to near the bottom, even if the liquid level of the refrigerant reservoir (36) moves up and down during operation of the machine, this liquid level will not change. It does not interfere with the adsorption effect of octyl alcohol floating in the water.
