（蒸発）作用を促進することによって被熱媒体の冷却作
用を実現するようになっている。In such an adsorption-type refrigeration apparatus, an adsorbate such as water is installed at the bottom of a vacuum vessel forming an adsorption tower, and an adsorbent such as zeolite or silica gel is installed above the vacuum vessel. By promoting the vaporizing (evaporating) action of the adsorbate by the agent, the cooling action of the medium to be heated is realized.

により加熱作用を実現する。When the refrigerant vapor adsorbing action to the adsorbent progresses and reaches a saturated state, the adsorbent is heated by heating means to release the refrigerant vapor (adsorbate) to activate the desorbing action. Is performed. Then, a heating effect is realized by the heat released during the desorption.

実現されるようになる。For example, according to Japanese Patent Application Laid-Open No. 230069/1990, at least two or more adsorption towers each having a built-in adsorbent and a heat transfer tube are used, and the body of each of the adsorption towers is connected so that the heat medium can circulate. At the same time, the adsorption and desorption steps are alternately switched so that one or more of the two or more adsorption towers has an operation step different from that of the other adsorption tower, and the reversible operation is performed. A refrigerating device has been proposed. By connecting the two adsorption towers directly with a heating medium pipe via a heater and a cooler in this way, for example, a refrigeration circuit as shown in FIG. 12 is formed. If switching is performed in accordance with the completion of the adsorption / desorption operation of the tower, each step of adsorption or desorption in each adsorption tower can be repeatedly executed, and a continuous refrigerating operation can be realized.

As described above, a heating heat medium from a heater or a cooling heat medium from a cooler is used for controlling the temperature of the adsorbent necessary for the adsorption / desorption action, and the supply direction thereof is, for example, as shown in FIG. 2 or FIG. By reversibly switching, an adsorption or desorption action is realized.

ものが必要となる問題がある。By the way, the heating input of the heating heat medium to the adsorbent of the adsorption column on the desorption side in the operation state of the heat pump cycle in FIG. 12 is represented by the heat input to the adsorbent. The heat quantity is determined by the inlet-side temperature and outlet-side temperature of the desorption-side adsorption tower. Therefore, assuming that the heating medium supply state of FIG. 2 or FIG. 3 is continued from the start of desorption to the completion of desorption, for example, as shown in the characteristics of FIG. 13, the inlet temperature gradually increases from about 60 ° C. and the outlet temperature about 40 ° C. It changes greatly like ab, cd. Therefore, naturally, there is a problem that the heating input heat amount in the heater needs to be large accordingly.

る。Further, the heat input of the heat pump cycle shown in FIG. 12 is only the amount of heating by the heater 3 to the desorption tower after all, and as shown in FIGS. If the length becomes longer, there is a problem that the load on the heater also increases due to the progress of the adsorption action on the adsorption tower side, while the heating efficiency decreases with the progress of the desorption action on the desorption tower side.

る。(1) The operation of the invention according to the first aspect In the adsorption refrigeration apparatus according to the first aspect of the invention, the first and second two heat exchangers each having an adsorbent in the adsorption chamber as described above. The two adsorption towers 1 and 2 are used, and the respective adsorption chambers of the respective adsorption towers 1 and 2 are connected endlessly through a heater 3 and a cooler 4, and the first and second two The heat medium heated or cooled by the heater 3 or the cooler 4 is alternately supplied and circulated in the reverse direction to the adsorbents of the heat exchangers with adsorbents of the adsorption towers 1 and 2 so that the adsorption / desorption operation is performed. In the adsorption type refrigeration apparatus, the first adsorption tower 1, the heater 3, the second
The first operation control state in which the entire heat medium circulation loop is communicated with the heat medium pipes 21, 22, 23, and 24 between the adsorption tower 2, the cooler 4, and the first adsorption tower 1, A heat medium circulation loop including only the adsorption tower 1 and the heater 3 or the cooler 4;
Two types of operation states, a second operation control state forming two sets of mutually interrupted heat medium circulation loops of the second adsorption tower 2 and a heat medium circulation loop of only the cooler 4 or the heater 3 (11, 18), (5,
6) and temperature sensors (S 1 , S 4 ) for detecting the temperature of the heat medium at the heat medium inflow / outflow portions of the first and second adsorption towers 1 and 2;
(S 2 , S 3 ), and when the temperature of the heat medium at the outlet of the adsorption tower on the adsorption side becomes equal to the temperature of the heat medium at the outlet of the adsorption tower on the desorption side, the heat medium circulation loop switching means ( 11-1
8) and (5, 6) are operated to switch from the first operation control state to the second operation control state.

り、加熱器３へは今まで加熱されていた一方側の吸着塔
２からの高温の熱媒が流入するので、該状態での加熱器
３への加熱入力は、その分低減される。Therefore, for example, desorption (regeneration) of the adsorbent by heating one of the first and second adsorption towers 1 and 2 shown in FIG. The flow of the heating medium for heating when the adsorbent is desorbed (regenerated) by heating the adsorption tower 1 is as shown in FIG. 3, for example. Since the high-temperature heat medium flows from the adsorption tower 2 on the side, the heating input to the heater 3 in this state is reduced correspondingly.
【００１８】しかし、時間が経つに連れて、当該一方側
吸着塔２の出口側熱媒の温度は低下し、他方側吸着塔１
の出口側の熱媒温度が上昇して行く。However, as time passes, the temperature of the heat medium on the outlet side of the one-side adsorption tower 2 decreases, and the temperature of the other-side adsorption tower 1 decreases.
The temperature of the heat medium on the outlet side increases.

幅に低減される。Then, when the temperature of the heat medium on the outlet side of the one-side adsorption tower 2 becomes equal to the temperature of the heat medium on the outlet side of the other-side adsorption tower 1, the heat medium circulation loop switching means (11 to 18)
By operating (5, 6), a heat medium circulation state is formed from the first operation state of FIG. 2 to the second operation state of FIG. 5, for example. In this way, the heating medium 3 from the one-side adsorption tower 2 whose temperature gradually decreases from the heating medium temperature at the time of the switching is not flown into the heater 3,
Conversely, the heat medium having a higher temperature flows through the other adsorption tower 1 whose temperature gradually rises, and the above-described FIG.
As compared with the second conventional configuration, the amount of heat required for the heater itself is greatly reduced.

Without this, a low-temperature heat medium is supplied from the outlet side of the same-side adsorption tower 2 whose temperature gradually decreases, so that the amount of heat required for cooling is greatly reduced.

応じた大きなものが必要となる問題がある。In the first operation control state of the first and second heat pump operation cycles shown in FIG. 2 or FIG. 3, the heating input of the heating heat medium to the adsorbent of the desorption-side adsorption tower is based on the regeneration of the adsorbent. It is expressed by the input calorific value.
Alternatively, if the heat medium circulation state in FIG. 3 is continued as it is until the adsorption / desorption operation is completed, for example, as shown in the characteristics of FIG. The temperature gradually rises from about 60 ° C. and about 40 ° C. at the time of switching of desorption, and greatly changes as a to b and c to d. Therefore, naturally, there is a problem that a large amount of heating heat necessary in the heater 3 is required.

A to b) and the outlet side temperature (c to d in FIG. 13). Therefore, in order to reduce the heating amount, it is preferable that the inlet temperature at the time of the adsorption / desorption switching is not reduced.

The flow of the heating medium for heating when the desorption (regeneration) is performed is as shown in FIG. 3, and the high-temperature heat from the second adsorption tower 2 which has been heated up to now is supplied to the heater 3. As the medium flows in, the heating input is reduced accordingly.

The openings 1 to 18 are opened to the side of the bypass pipes 25 to 28 to form a heat medium circulation state in the second operation state as shown in FIG. By doing so, the heat medium from the second adsorption tower 2 whose temperature gradually decreases from the heat medium temperature at the time of switching of the three-way switching valves 11 to 18 is prevented from flowing into the heater 3. Conversely, a heat medium of at least 80 ° C. or more flows through the first adsorption tower 1 whose temperature gradually rises, so that compared with the case of the above-described conventional configuration (FIG. 12), The amount of heat required for the heater 3 itself is greatly reduced (see the characteristics in FIG. 6).

Since the low-temperature heat medium is supplied from the outlet side of the second adsorption tower 2 whose temperature gradually decreases, the amount of heat required for cooling is greatly reduced.
