Abstract

PURPOSE:To get a superior heating performance and a cooling performance and shorten a heating time and a cooling time for a reactivation process by a method wherein metallic nets and punched metal plates are held among several structures of honeycomb member having adsorptive material carried therein so as to make an adsorptive operating member and this member is installed to make a reversible heat generating and cooling generator. CONSTITUTION:In an adsorptive operating member 2 stored in a container 1 a complex member of alumina silica fiber is employed as its honeycomb base member. As an adsorptive material, zeorite 13X is adhered, carried and formed. As a valve 5 is opened, operating liquid 4 to be adsorbed which is stored in the container 3 is evaporated due to a heard adsorption force of the adsorption member 2, its vapor 6 may pass through pipes 9 and 9a and is adsorbed into the adsorptive operating member 2 stored in the container 1. At this time, since the adsorption operating member 2 may promote forcedly an adsorption of the operating liquid vapor 6 to be adsorbed, a temperature of the container 1 is increased and a heating part is formed. Since an occurrence of the operating liquid vapor 6 to be adsorbed is thermo-insulatively and rapidly promoted in a continuous manner, a rapid reduction of the temperature of the operating liquid 4 to be adsorbed is realized. Accordingly, the container 1 can be utilized as cooling material.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention effectively adsorbs the adsorbed liquid vapor and desorbs the adsorbed liquid component by heating the adsorbing body involved in the reactivation process after adsorption. This invention relates to a reversible heating and cooling generator that can be used to generate heat and cold.

Conventional technology In the past, an adsorbent was used as the operating body, and the adsorbent and the operating liquid to be adsorbed were housed in separate containers, connected by a communicating pipe equipped with a valve that could be shut off and opened at will, and the system was evacuated. Apparatuses capable of heating and cooling are known, for example, from Japanese Patent Publication No. 61-4008, Japanese Patent Publication No. 61-6307, and Japanese Patent Application Laid-open No. 60-232242. In all of these techniques, the adsorbent, which is the operating body, is a single flake, granule, or molded body. In addition, the adsorbent material, which is the operating body, is specially designed for the purpose of facilitating the adsorption of the adsorbed liquid vapor, improving the transfer of heat generated by this, and effectively desorbing the adsorbed liquid component involved in the reactivation process. In JP-A-60-232242 and JP-A-59-206047, a measure was taken in which voids in a three-dimensional net structure of a metal porous body were filled with zeolite.

Problems to be Solved by the Invention In such conventional reversible heating/cooling generators, the adsorbed liquid vapor slowly diffuses through the gaps between the particles of the adsorbing body, so it takes time for adsorption to proceed. In short, it will be extremely slow.

In addition, the heat generated by the adsorption member due to the adsorption of the liquid vapor to be actuated is not sufficiently diffused, resulting in a temperature higher than the temperature range in which the adsorption member has sufficient adsorption capacity, so rapid adsorption action cannot be expected. It was long. Furthermore, the heat propagation due to heating during the reactivation treatment of the adsorbing body whose adsorption capacity has been exhausted was poor, and furthermore, the desorbed adsorbed liquid vapor did not scatter smoothly, making this operation time-consuming. there were.

The object of the present invention is to provide a reversible heat generating cooling generator that solves the above problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention aims to provide a method for solving the above-mentioned problems by distributing a material between a large number of honeycomb-like structures carrying adsorbents, such as metal nets, punched metal plates, porous metal bodies, and metal fibers. selected 1
Seeds or more are sandwiched and stacked to form an adsorption action body, and a reversible heating/cooling generator is constructed with this attached.

Function The adsorption structure used in the present invention is made up of a large number of individual honeycomb-like structures carrying adsorbent, and a metal mesh, punched metal plate, porous metal body, or metal that is a good conductor of heat is placed between the individual honeycomb structures. One or more selected fibers are combined and stacked in a sandwiched state. Therefore, the liquid vapor to be adsorbed that has flowed into the through holes of the honeycomb structure passes through while being successively adsorbed, and flows out to the sandwiched metal layers in b. Here, the liquid vapor to be adsorbed is disturbed to homogenize its concentration, and then moves to the through holes of the next honeycomb-shaped solid. Because this kind of movement is repeated many times with the sandwiched metal bodies, the adsorption action of the liquid vapor to be adsorbed is much faster than in the case of a conventional uncut honeycomb or a particulate or flake adsorption member. The speed and amount of adsorption into the body will be greatly improved. Adsorption bodies generally have poor thermal conductivity, which is comparable to that of insulating bricks, and the metal bodies placed between the honeycomb-like bodies also play a role in promoting the dissipation of self-heating due to adsorption, so the suction bodies have a poor adsorption force. Since it is possible to maintain the temperature within the same temperature range, the inherent adsorption ability can be maintained. Furthermore, by heating the adsorption body whose adsorption power has run out, the adsorbed liquid vapor can be discharged and the adsorption activity can be regained.

It also serves to smoothly transfer heat from the heat source to the adsorption member during reactivation, thereby shortening the time. In addition, it becomes possible to speed up the cooling process after the reactivation process.

EXAMPLE An example of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 showing the basic configuration of the reversible exothermic/cold generator of the present invention, 1 is a container for accommodating the adsorption member 2 used in the present invention, which is based on the configuration shown below, and 3 is the adsorbed member. This is a container that contains liquid 4. The valve 5 is connected to a vibrator 9, 9a that guides the liquid vapor 6 to be adsorbed, and maintains a vacuum inside the system after the initial heating vacuum treatment is completed.

Next, this operation will be explained. In FIG. 1, valve 5
When opened, the adsorbed liquid 4 contained in the container 3 evaporates due to the strong adsorption force of the adsorption body 2 contained in the container 1, and the vapor 6 passes through the pipes 9 and 9a and enters the container 1. It is adsorbed by the suction operating body 2 housed therein.

At this time, the adsorption body 2 strongly promotes the adsorption of the adsorbed liquid vapor 6, so that the temperature of the container 1 rises and a heated portion is formed. Since the generation of the adsorbed working liquid vapor 6 continues to be rapidly and adiabatically promoted, the temperature of the adsorbed working liquid 4 suddenly decreases. Therefore, the container 2 can be used as a cooling section.

The reversible heating/cooling generator of this embodiment shown here is an example, and the shape is not limited to this as long as the principle that heating and cooling can be performed by adsorption is satisfied.

Next, the suction action body used in this example will be explained. FIG. 2 is a partial cross-sectional view showing the suction body of this embodiment housed in a container. In this figure, the adsorption action body 2 housed in a container 1 is formed by using an aggregate of alumina-silica fibers as a honeycomb-like base, adhering and supporting zeolite 13X as an adsorbent, and forming holes in the honeycomb-like structure. A wire net 3 made of steel wire with a wire diameter of 1 mm is sandwiched between each of the 5 mm thick pieces cut perpendicularly to the vertical direction, and the adsorption action body is made by stacking them in multiple layers. In addition, when water is used as the adsorption liquid, water vapor that has moved due to the strong adsorption power of zeolite passes through the holes in the honeycomb structure while being adsorbed by the zeolite, and is not adsorbed. The water vapor is agitated by the sandwiched metal mesh and the concentration is made uniform, and then it moves to the next hole and is adsorbed. The temperature drop in the cooler during this operation, as shown in curve 1 in Figure 3, is larger than the cooling effect shown in curve 2 when it is filled with a conventional particulate compact with a diameter of about 3IIIffl. Shows strong cooling properties. When the suction ability of the suction body is lost due to the continuation of such suction operation, the suction body is heated from the outside to perform a reactivation process. In this case, compared to the present example shown in curve 1 in FIG. 4, where the horizontal axis represents the treatment time and the vertical axis represents the desorption of water, the situation is as follows: curve 2, which represents the conventional product. Since the amount of water desorbed is small, the time for reactivation treatment can be shortened. In addition to the above, the honeycomb substrate for forming the adsorption member effectively used in this embodiment may be a sintered ceramic body, porous carbon fiber, or a thin metal plate. In addition to the above-mentioned adsorbent components, zeolite 10
X-A3, A4, A5, Y types, silica gel, silica alumina gel, and activated carbon are effective. The liquid to be adsorbed used in this embodiment may be water having a single composition, a single organic solvent, a mixture of water and an organic solvent, or even a fluorocarbon compound or ammonia. The cutting thickness of the honeycomb structure used in this example is not particularly limited;
It is sufficient that the thickness is such that heat can be transferred well to the metal body sandwiched between the two bodies, and furthermore, the adsorbed liquid vapor can be disturbed at v4'l. In addition, in this example, the metal body is a conductive wire, but it is also possible to use a punch metal plate or
Similar results can be obtained by using porous metal bodies and metal fibers, and similar results can also be obtained by using these in combination.

Effects of the Invention As explained above, one or more of metal nets, punched metal plates, porous metal bodies, metal fibers, etc., is formed between a large number of cut honeycomb-shaped structures containing adsorbents. By combining the above, sandwiching and stacking them to form an adsorption action body, and attaching this to form a reversible exothermic cooling generator, excellent heating and cooling performance can be obtained, and the heating and cooling times involved in reactivation processing can be shortened. This has made it possible to provide a reversible heat/cold generator that can be used in a variety of ways.
