Description

  The present invention relates to an absorption heat generation control method and an absorption heat pump device of a second type absorption heat pump device that generates high-temperature water and steam using exhaust heat such as hot water as a heat source.

In cogeneration using an engine, steam produced by recovering heat from exhaust gas is used effectively, but jacket hot water has little effective use other than hot water supply, and often dissipates heat in a cooling tower. Absorption heat pumps that generate high-temperature heat from such a low-quality heat source such as waste water or waste steam are known from, for example, Patent Document 1 and Patent Document 2. An absorption heat pump that generates high-temperature and high-pressure steam from low-temperature exhaust heat has also been proposed.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration example (first embodiment) of an absorption heat pump apparatus according to the present invention. The absorption heat pump apparatus 100-1 includes an absorber A, an evaporator E, a regenerator G, a condenser C, a solution heat exchanger 10, a solution pump 11, a concentrated solution pipe 12, a diluted solution pipe 13, a refrigerant pump 14, and a refrigerant. Pipe 15, heat source hot water pipe 16, heat source hot water pipe 17, cooling water pipe 18, feed water pump 19, feed water preheating heat transfer pipe 20, steam generation heat transfer pipe 21, refrigerant bypass pipe 30, refrigerant bypass valve 31, refrigerant return pipe 32, refrigerant The return valve 33 is configured.

  In the absorption heat pump apparatus 100-1 having the above structure, the concentrated solution in the regenerator G is heated by the solution pump 11 through the concentrated solution pipe 12 and the heated side of the solution heat exchanger 10, and then the absorber. It is sprayed in A. The concentrated solution sprayed in the absorber A absorbs the refrigerant vapor flowing from the evaporator E to generate absorption heat, and heats the heated medium flowing in the vapor generation heat transfer tube 21 with this absorption heat. The dilute solution whose concentration has been reduced by absorbing the refrigerant vapor passes through the dilute solution pipe 13, passes through the heating side of the solution heat exchanger 10, and returns to the regenerator G to be dispersed. The dilute solution sprayed on the regenerator G is heated by the heat source hot water flowing through the heat source hot water pipe 17, generates refrigerant vapor and is concentrated into a concentrated solution, and goes through the solution cycle.

  The refrigerant vapor generated in the regenerator G is guided to the condenser C, and is cooled and condensed by the cooling water flowing through the cooling water pipe 18 to become a refrigerant liquid. The refrigerant liquid is sent from the refrigerant pump 14 through the refrigerant pipe 15 into the evaporator E and dispersed. The sprayed refrigerant liquid is heated and evaporated by the heat source hot water flowing in the heat source hot water pipe 16 and guided to the absorber A. The above is the cycle of the refrigerant and the solution.

  On the other hand, the medium to be heated (water) is pressurized by the feed water pump 19 and guided to the feed water preheating heat transfer tube 20. In the feed water preheating heat transfer tube 20, the refrigerant vapor generated in the evaporator E is condensed to heat the medium to be heated (water), and then the concentrated solution generates refrigerant vapor in the vapor generation heat transfer tube 21 in the absorber A. It is heated by absorption heat generated by absorption and becomes water vapor. As described above, by supplying the heat source hot water to the heat source hot water pipes 16 and 17 and the cooling water to the cooling water pipe 18 of the absorption heat pump 1, the absorber A can generate high-temperature absorption heat.

  In addition, as an installation place of the feed water preheating heat transfer tube 20, heat recovery from the solution circulation system, direct heating with heat source hot water, condensation heat of the condenser C, or the like can be used. Moreover, you may combine these. Further, a heat exchanger may be installed in the refrigerant pipe 15 to preheat the refrigerant supplied to the evaporator E.

  FIG. 2 shows an absorption cycle of the absorption heat pump shown in FIG. 1 on a Duering diagram. In the absorption heat pump, when the demand for high-temperature heat decreases, it is necessary to reduce the amount of heat generated by the absorber A. A method of reducing the amount of heat input by simply reducing the flow rate of the heat source hot water and reducing the amount of heat generated in the absorber A is considered, but considering the jacket water of the gas engine cogeneration as an example of the heat source hot water, Since it is necessary to always remove heat because it is a cooling water, it is necessary to ensure the heat radiation of the heat source hot water. For example, the heat source hot water can be cooled with the cooling water to cool the heat source hot water. In this case, a large heat exchanger is required as described above. In addition, it is possible to use a motorized valve or the like without using a heat exchanger to mix waste heat water with cooling water to dissipate heat, but in this case the motorized valve has a large diameter as described above, which is expensive. In addition, considerable space is required for handling large-diameter piping.

Therefore, in this embodiment, the configuration in which the refrigerant liquid held in the condenser C is guided to the regenerator G by opening the refrigerant bypass valve 31 of the refrigerant bypass pipe 30 and the concentrated solution of the regenerator G is diluted. . This will be explained with reference to the Duling diagram of FIG. 2. A dilute solution having a concentration ξ1 from the absorber A is concentrated in the regenerator G to become ξ2, and then the refrigerant liquid is introduced from the condenser C through the refrigerant bypass pipe 30 and mixed. When diluted, the concentration becomes ξ ^* . The solution having this concentration ξ ^* is sent to the absorber A by the solution pump 11. As a result, the concentration range of the cycle is narrowed, and a part of the energy consumed for concentration in the regenerator G (the amount of heat necessary for concentration from ξ ^* to ξ2) passes through the cooling water pipe 18 of the condenser C. Since COP is reduced by radiating heat to the cooling water, the amount of heat generated in the absorber A can be reduced. In FIG. 2, TA, TC, TE, and TG respectively indicate the temperature of the absorber A, the temperature of the condenser C, the temperature of the evaporator E, and the temperature of the regenerator G.

  At this time, the amount of heat generated in the absorber A decreases, while the amount of heat input to the evaporator E decreases, so that the amount of solution circulation, that is, the flow rate of the solution pump is not reduced so as to reduce the amount of heat of the heat source hot water. Need to be increased. This may be a throttle valve provided on the discharge side of the solution pump, or the rotational speed of the solution pump 11 may be controlled by inverter control or the like.

  Further, as another method for securing the heat input amount of the evaporator E, the absorption heat pump of FIG. 1 is provided with a refrigerant return pipe 32 and a refrigerant return valve 33 connected from the evaporator E to the condenser C. The high-temperature refrigerant liquid that has not evaporated is allowed to flow into the condenser C and dissipate heat to the cooling water passing through the cooling water pipe 18. According to this method, the solution pump 11 can be downsized because it is not necessary to provide an excessive margin for the flow rate of the solution pump 11.

  FIG. 3 is a diagram showing a configuration example (second embodiment) of the absorption heat pump device according to the present invention. The absorption heat pump apparatus 100-2 differs from the absorption heat pump apparatus 100-1 in FIG. 1 in that the refrigerant bypass pipe 30 and the refrigerant bypass valve 31 in FIG. The bypass valve 41 is provided. That is, only the connection location of the refrigerant bypass pipe and the refrigerant bypass valve is different. Other components, absorption cycle, flow, etc. are the same as those of the absorption heat pump of FIG.

  As described above, in the present absorption heat pump 100-2, the refrigerant liquid sent to the evaporator E through the refrigerant pipe 15 by the refrigerant pump 14 is branched from the refrigerant pipe 15 by the refrigerant bypass pipe 40 and led to the absorber A. ing. That is, here, the refrigerant liquid held in the condenser C is caused to flow to the solution inlet side of the absorber A by opening the refrigerant bypass valve 41 of the refrigerant bypass pipe 40 and flows into the absorber A from the regenerator G. The concentrated solution is diluted.

This will be described with reference to the Duering diagram shown in FIG. 4. The concentrated solution having the concentration ξ2 flowing from the regenerator G into the absorber A is mixed with the refrigerant liquid from the refrigerant bypass pipe 40 and diluted to a concentration ξ ^* . Then, it is dispersed in the absorber A, absorbs the refrigerant vapor from the evaporator E, becomes a dilute solution having a concentration ξ1, and is sent to the regenerator G. As a result, similar to the absorption heat pump shown in FIG. 1 described above, the cycle concentration range becomes narrower, and a part of the energy consumed for concentration in the regenerator G (the amount of heat necessary for concentration from ξ ^* to ξ2) is reduced. Since heat is dissipated in the cooling water of the condenser C and COP is reduced, the amount of heat generated in the absorber A can be reduced. Further, in this embodiment, in order to secure the heat input amount of the evaporator E, the refrigerant return pipe 32 and the refrigerant return valve 33 connected from the evaporator E to the condenser C are provided in FIG. A high-temperature refrigerant liquid is caused to flow into the condenser C, and the heat is radiated to the cooling water.

  FIG. 5 is a diagram showing a configuration example (third embodiment) of an absorption heat pump device according to the present invention. In the present absorption heat pump device 100-3, the refrigerant liquid in the condenser C is sent to the heated side of the refrigerant heat recovery device 50 through the refrigerant pipe 15 by the refrigerant pump 14, heated, and further sent to the evaporator E to be dispersed. The The refrigerant liquid that has not evaporated in the evaporator E flows through the refrigerant return pipe 51 and flows into the heating side of the refrigerant heat recovery unit 50, is cooled, and returns to the condenser C. Thereby, without installing a refrigerant spray pump, the amount of refrigerant sprayed in the evaporator E can be increased, and the sensible heat loss caused by returning the non-evaporated refrigerant in the evaporator E to the condenser C can be reduced. .

  The absorption heat pump 100-3 is configured to circulate and spray the refrigerant while recovering the heat as described above, and the refrigerant heat recovery unit 50 is connected to the refrigerant pipe 15 that sends the refrigerant liquid from the condenser C to the evaporator E. A refrigerant bypass pipe 52 and a refrigerant bypass valve 53 are installed so as to bypass. At the time of capacity control, the refrigerant bypass valve 53 is opened so that part or all of the refrigerant liquid sent from the condenser C to the evaporator passes through the refrigerant bypass pipe 52 so that it does not evaporate in the evaporator E. The amount of heat recovered from the high-temperature refrigerant liquid by the refrigerant heat recovery unit 50 can be reduced, and the high-temperature refrigerant liquid flows into the condenser C and dissipates heat to the cooling water. As a result, as described in the first embodiment and the second embodiment, the amount of heat input to the evaporator can be ensured during capacity control, so that the capacity of the solution pump 11 is excessive. There is no need to increase the size, and the solution pump 11 can be downsized.

  The refrigerant liquid of the condenser C is mixed with the concentrated solution of the regenerator G through the pipe 54 and the valve 55 branched from the discharge pipe of the refrigerant pump 14. Thereby, the refrigerant liquid of the condenser C can be sent into the regenerator G without physical restrictions using the discharge pressure of the refrigerant pump 14. On the other hand, in the absorption heat pump having the configuration shown in FIG. 1, it is necessary to make the refrigerant liquid level of the condenser C higher than the concentrated solution liquid level of the regenerator G. This is a physical restriction on the arrangement of the heat exchanger. There is.

  In the above embodiment, the exhaust heat form is the engine jacket warm water, but the present invention is not limited to this, and the present invention can be similarly applied to driving the absorption heat pump with factory exhaust heat. Moreover, not only warm water but another heat medium may be used.

  Further, in the above embodiment, water is used as the medium to be heated, and the steam is generated by heating with the steam generation heat transfer tube 21, but the phase may not be changed and may be taken out as high temperature water. Further, the heat medium is not limited to water.

  In the absorption heat pump device 100-1 of FIG. 1 as the first embodiment, the connection destination of the refrigerant bypass pipe 30 is not limited to the can body of the regenerator G, but from the suction pipe and the absorber A of the solution pump 11. It may be upstream of the inlet of the regenerator G of the dilute solution.

  In the absorption heat pump apparatus 100-2 of FIG. 3 which is the second embodiment, the connection destination of the refrigerant bypass pipe 40 is not limited to the concentrated solution inlet side from the regenerator G of the absorber A, but of the absorber A. It can be inside the can body.

  In the absorption heat pump apparatus 100-3 of FIG. 5 as the third embodiment, the refrigerant bypass pipe 52 is not limited to the refrigerant pipe 15 from the condenser C to the evaporator E, but is the refrigerant return side, that is, the evaporator. You may install in the refrigerant | coolant return piping 51 which goes to the condenser C from E.

  In the above embodiment example, the heating amount of the heating medium of the single-stage temperature rising type absorption heat pump has been described. However, although not shown, the present invention can be similarly applied to a multi-stage temperature rising type absorption heat pump.
