【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for efficiently operating an adsorbent-based heat pump that pumps heat from a low-temperature heat source by simply switching a valve. An object of the present invention is to provide a heat pump that can pump heat from a low-temperature heat source without using power, and in particular to provide an algorithm for optimizing its operation. The heat pump of the present invention that achieves this objective and its operating method will be explained with reference to the drawings. As shown in FIG. 1, the basic configuration of the heat pump of the present invention is that an evaporator 2 and a condenser 3 are connected so that a working fluid can flow to an adsorption tower 1 containing an adsorbent. An on-off valve 4 is interposed in the working fluid passage connecting the adsorption tower 1 and the condenser 2, and an on-off valve 5 is interposed in the working fluid passage connecting the adsorption tower 1 and the condenser 3. configured to selectively flow the fluid for use. The adsorption tower 1 is filled with an adsorbent such as activated carbon,
A fluid passage 6 is provided to enable heat exchange with the activated carbon.
Cooling fluid 7 and heating fluid 8 are made to flow selectively through this fluid passage 6 by operating valves 9 and 10. As the cooling fluid 7, low-temperature waste water or low-temperature air can be used, and as the heating fluid 8, high-temperature waste water or high-temperature air can be used. Figures 2 and 3 show a specific example of this adsorption tower 1, with a cylindrical container 1
A mesh working fluid passage 12 is provided in the axial direction at the center of the cylindrical container 11, and the activated carbon 13 is loaded into the inner space of the cylindrical container 11 surrounded by the working fluid passage 12, and the fluid passage is used to heat and cool the activated carbon. , a jacket 6a that covers the outer peripheral surface of the cylindrical container 11, and a large number of pipes 6b that penetrate the activated carbon layer.
is provided. The evaporator 2 consists of a closed container in which a working fluid such as water is sealed. The evaporator 2 and the adsorption tower 1 are connected by a working fluid passage 15 (FIG. 1),
An on-off valve 4 is interposed in this working fluid passage 15 .
In the adsorption tower 1 shown in FIGS. 2 and 3, the working fluid passage 12 of the net body is the working fluid passage 15 of the on-off valve 4 interposed.
connected to. The evaporator 2 itself constitutes a heat exchanger that exchanges heat with the low temperature heat source fluid 17, and as shown in FIG. Although not shown, a jacket through which the low-temperature heat source fluid 17 flows may be installed around the periphery of the evaporator 2. It is also beneficial to appropriately attach fins or the like to increase heat exchange efficiency. The condenser 3 also consists of a closed container, and is connected to the adsorption tower 1 through a working fluid passage 16 (FIG. 1) in which an on-off valve 5 is interposed. In the adsorption tower 1 shown in FIGS. 2 and 3, the working fluid passage 12 of the network is connected to the working fluid passage 16 of the on-off valve 5 interposed therebetween. This condenser 3
In order to efficiently extract the heat generated in the evaporator 2, a coil 20 through which the external fluid 19 flows is provided, or a jacket is installed, and fins or the like may be installed as the case may be. The evaporator 2 and the condenser 3 are connected by a communication passage 21 for returning the liquid working fluid condensed in the condenser 3 to the evaporator 2 in liquid form, and a normally closed valve 22 is connected to this passage. It is advisable to attach it to the communication path 21. The operation mode of the heat pump configured in this way will be explained next. [Operation 1] Open the valve 9 and close the valve 10, cool the adsorbent by flowing the cooling fluid 7 into the fluid passage 6 of the adsorption tower 1, open the on-off valve 4, and close the on-off valve 5. In this way, the working fluid in the evaporator 2 is adsorbed onto the adsorbent. That is, the working fluid is evaporated in the evaporator 2, and the vapor is adsorbed by the adsorbent in the adsorption tower 1. With this operation, latent heat is released in the adsorption tower 1. [Operation 2] After continuing [Operation 1] for a certain period of time, close the on-off valve 4, open the on-off valve 5, open the valve 10, close the valve 9, and open the fluid passage 6 of the adsorption tower 1.
The heating fluid 8 is passed through to heat the adsorbent. That is, the adsorbent is heated to desorb the working fluid adsorbed thereon, and the working fluid is condensed in the condenser 3, and the heat of condensation is released. [Operation 3] When the amount of condensation in the condenser 3 reaches a certain level, close the on-off valves 4 and 5, open the valve 22,
The working fluid in the condenser 3 is returned to the evaporator 2. By repeating this series of operations, heat is pumped up from the evaporator 2 and released in the adsorption tower 1, allowing the evaporator 2 to function as a refrigerator and the adsorption tower 1 to function as a temperature riser. In addition, heat can be released to the condenser 3 through the desorption operation, and the fluid that has reached a higher temperature than the heat source fluid supplied to the evaporator 2 can be taken out in the adsorption tower 1 or in the condenser 3. . Therefore, for example, various wastewater and exhaust gases (exhaust air) from the process are transferred to the evaporator 2.
It is used as the heat source fluid 17 flowing to the side of the cooling fluid 17 and the heat source fluid 19 flowing to the condenser 3, and the cooling fluid 7 flowing to the adsorption tower 1.
When a process fluid is flowed as the heating fluid 8, the high temperature fluid necessary for the process can be taken out from the adsorption tower 1 by simply opening and closing the valve, and the lower temperature fluid can be taken out from the evaporator 2. can be taken out. If the combination of working fluid and adsorbent is appropriately selected, for example, if water is used as the working fluid and activated carbon is used as the adsorbent, a heat pump that is easy to handle without problems such as corrosion or toxicity can be obtained. By the way, when actually driving such a heat pump using an adsorbent, it is necessary to perform the driving optimally. The inventors of the present invention conducted repeated experiments on the optimal operation algorithm, and found that the adsorption operation in which the working fluid of the evaporator 2 is adsorbed onto the adsorbent in the adsorption tower 1 is terminated when the adsorption rate reaches the maximum. The working fluid adsorbed in the adsorption tower 1 is transferred to the condenser 3
It has been found that the operating method that yields the best results is to switch the on-off valves 4 and 5 so that the desorption operation for condensation is terminated when the desorption speed reaches its maximum. Below, we will explain about this optimal driving algorithm.
This will be explained in detail with reference to experimental results conducted by the present inventors. FIG. 4 is an equipment layout system diagram of the apparatus used in the experiment, and the same numbers as in FIG. 1 indicate the same equipment contents as explained in FIG. 1. The structure of the adsorption tower 1 used was the same as that shown in FIG. 2, and a water jacket was provided around the outer periphery of the adsorption tower 1. In FIG. 4, 24 is a low-temperature constant temperature bath (chilled water, 18°C), and the cold water therein is supplied to the evaporator 2 and condenser 3 for transfer of heat, and is also used for cooling the adsorption tower 1. Fluid 7 (first
Also used as (Figure). Further, 25 is a high temperature constant temperature bath (hot water, 62° C.), and the hot water therein is used as the heating fluid 8 (FIG. 1) of the adsorption tower 1.
A valve 2 is installed in the cold water pipe between the low temperature constant temperature bath 24 and the adsorption tower 1.
6 and 27 are provided, and valves 28 and 29 are provided in the hot water pipeline between the high temperature constant temperature bath 25 and the adsorption tower 1. The opening and closing operations of the valves 26 to 29, the on-off valves 4 and 5 are controlled by a computer 30.
It is carried out by the directive of Temperature meters are installed at various points in the system.
is attached, and this temperature information is sent to a recorder 31 and a digital voltmeter 32 of a computer 30 and used as a control signal. On the other hand, both thermostats 2
The control operation of the heat sources 33 and 34 for controlling the water temperatures of water 4 and 25 is carried out by driving the power controller 35 in accordance with commands from the computer 30. Further, the opening/closing operation of each valve is performed by driving the valve driver 36. The adsorbent filled in the adsorption tower 1 is activated carbon,
Water is used as the working fluid. To explain the test procedure, first, evaporator 2,
A low-temperature constant temperature bath 2 is installed at each location of the condenser 3 and adsorption tower 1.
When cold water is supplied from 4 and kept at a constant temperature and the on-off valve 4 is opened, the working fluid evaporates from the evaporator 2 and is adsorbed by the adsorbent. At this time, the temperature of the evaporator 2 decreases and the temperature of the adsorption tower 1 increases. next,
The on-off valve 4 is closed, the valves 26 to 29 are switched, and hot water is supplied from the high temperature constant temperature bath 25 to the adsorption tower 1 to heat it. When the on-off valve 5 is opened, the adsorbed working fluid is condensed into the condenser 3. This regenerates the adsorbent and returns it to its initial state. Through this series of operations, the evaporator 2 becomes a refrigerator and a low heat source is obtained. The test results shown below are the results of implementing this refrigeration system, but the following temperature raising system can also be easily implemented. That is, first of all, the adsorption tower 1
The evaporator 2 is heated with hot water in a high temperature constant temperature bath 25, and the condenser 3 is cooled with cold water in a low temperature constant temperature bath 24. When the on-off valve 4 is opened, the working fluid is adsorbed by the adsorbent, and the adsorption tower 1 becomes high in temperature due to the heat of adsorption. With this operation, the adsorption tower 1 becomes a temperature riser and can obtain a high temperature higher than the supply temperature. Regeneration of the adsorbent in this case is similar to that of a refrigeration system. FIG. 5 shows the relationship between the amount of adsorption of working fluid and time when implementing the refrigeration system. Measurement starts at point A, and adsorption starts at point B. At this time, the suction is stopped at the point where the slope {(Q 1 −Q 0 )/(t C −t A )} from point A is maximum, that is, contact point C. The slope according to the above equation is the adsorption rate referred to in this specification. Next, the adsorption tower 1 is heated, but since the valve is closed, there is no change in the amount of adsorption. At point D, when the temperature reaches 60℃, open the valve and start desorption. At that time, the slope from point C where adsorption was stopped | (Q 1 − Q 0 )/
The valve is closed at point A′ where (t A ′−t C ) | is maximum, and the same procedure is repeated from point B′ where the adsorbent is cooled to 20°C. The slope from this point C is the desorption rate referred to in this specification. Figure 6 shows an example of the temperature change of the adsorbent when the apparatus shown in Figure 4 is operated according to this algorithm (the temperature of the cold water and hot water flowing into the adsorption tower 1 are 18
℃, 62℃). A, B, C,... in Figure 6
correspond to the symbols in FIG. As seen in FIG. 6, when adsorption starts, the adsorbent temperature rises due to the generation of adsorption heat. Then, hot water is poured into the jacket of adsorption tower 1, and when the adsorbent temperature reaches 60°C, the valve is switched to connect condenser 3 and adsorption tower 1, and the working fluid is desorbed and condensed into condenser 3. I'm going to go. At this time, latent heat is removed from the adsorption tower 1 and the adsorbent temperature decreases. In the example shown in Figure 6, the average of three measurement points is used as the representative temperature of the adsorbent, and the switching period is almost constant each time (adsorption time is 43 minutes, desorption time is 24 minutes, and one cycle is 92 minutes). ). In order to confirm the optimality of this algorithm, Table 1 shows examples of the results of operation with the adsorption/desorption time (period) fixed at various values. "Optimum operation" in Table 1 is the above-mentioned embodiment of the present invention. As is clear from the results in Table 1, the adsorption operation in which the working fluid in the evaporator 2 is adsorbed onto the adsorbent in the adsorption tower 1 is terminated when the adsorption rate reaches its maximum, and the working fluid adsorbed in the adsorption tower 1 is It can be seen that when the algorithm of the present invention is used to switch the on-off valves 4 and 5 so that the desorption operation of condensing the heat in the condenser 3 is terminated when the desorption speed reaches the maximum, the heat pumping speed becomes the highest. . 【table】
