Description

  The present invention includes an adsorber comprising a set of two adsorbers having a built-in adsorbent and functioning as an adsorbing tank or a desorbing tank for a refrigerant, and an evaporator and a condenser having flow paths that can communicate with the adsorbers. The present invention relates to an adsorption refrigeration system that prevents a reduction in refrigeration capacity and saves energy consumption even when the amount of heat of the heat medium for regeneration of the adsorbent supplied to the adsorber is insufficient. .

  Conventionally, an adsorption refrigerator is known as a refrigerator using water which is a natural refrigerant. As shown in FIG. 4, the adsorption refrigeration machine 50 includes a pair of adsorbers 51a and 51b that incorporate an adsorbent and function as a refrigerant adsorption or desorption tank, and the adsorbers 51a and 51b. An evaporator 52 having a flow path communicable with each other, a flow path capable of communicating with each of the adsorbers 51a and 51b, and a condenser having a flow path for supplying condensed refrigerant to the evaporator 52 53 is a closed system.

  The adsorption refrigerator 50 causes one adsorber 51a to function as a refrigerant adsorption tank and the other adsorber 51b to function as a refrigerant desorption tank, and the evaporator 52 and one adsorber 51a. The other adsorber 51b and the condenser 53, the one adsorber 51a functions as a refrigerant desorption tank, and the other adsorber 51b functions as a refrigerant adsorption tank. The operation mode in which the evaporator 52 communicates with the other adsorber 51b and the one adsorber 51a communicates with the condenser 53 is alternately switched. As a result, cold energy is produced by heat exchange with the heat of vaporization generated as the refrigerant evaporates in the evaporator 52.

  The adsorbent filled in the adsorbers 51a and 51b is desorbed (regenerated) when heated to about 60 ° C. or higher, and exhaust heat from a boiler, solar heat, etc. can be used as a heat source for the regeneration. Recommended.

  As such an adsorption refrigeration machine, the following Patent Document 1 discloses that a refrigerant pump desorbed from an adsorbent by an adsorber is disposed by a suction pump in a refrigerant passage from an adsorber to a condenser. As it is sucked and pressurized, it enters the condenser and condenses.At the same time, the pressure at the inlet side of the suction pump decreases due to suction.Therefore, the equilibrium pressure relationship is lost, and more refrigerant vapor is discharged from the adsorbent in the adsorber. A chemical heat pump is disclosed.

Japanese Patent Laid-Open No. 11-37596

  However, exhaust heat or solar heat used as a heat source for adsorbent regeneration is not a stable supply source that fluctuates depending on the operating conditions of the boiler and the weather, so if there is no exhaust heat or solar heat supply Although the situation that the heat source for regeneration becomes zero may occur, the chemical heat pump described in Patent Document 1 can forcibly discharge the refrigerant vapor from the adsorbent by suction of the suction pump until such a case. It was n’t like that.

  As described above, when the heat source for regeneration is insufficient, the adsorbent is not sufficiently regenerated, which causes a problem that the adsorbed amount of the adsorbent decreases. As a result, the pressure in the evaporator rises, the refrigerant hardly evaporates in the evaporator, and the generation of heat of vaporization is suppressed, so that the temperature of the produced cold heat rises. Thus, there has been a problem that the refrigerating capacity is lowered due to insufficient regeneration (desorption) of the adsorbent.

  On the other hand, when a heat source device for separately heating the heat medium is provided to make up for the shortage of the heat source for regeneration, there is a problem that the operating efficiency is lowered because the amount of consumed energy increases accordingly.

  Accordingly, a main object of the present invention is to provide an adsorption refrigeration system that prevents a reduction in refrigeration capacity and saves energy.

In order to solve the above-mentioned problems, the present invention according to claim 1 is provided with a regeneration flow path that functions as a refrigerant adsorption tank or a desorption tank with a built-in adsorbent and through which at least a heat medium for regenerating the adsorbent flows. A set of two tanks provided, an evaporator provided with a flow path capable of communicating with each of the adsorbers, a flow path capable of communicating with each of the adsorbers, and condensed refrigerant to the evaporator A condenser having a flow path for feeding,

An adsorption refrigeration system is provided in which the refrigerant compressed by operation control of the compressor can be supplied to the condenser when the amount of heat of the heat medium is insufficient.

  The invention described in claim 1 is a first embodiment of the adsorption refrigeration system according to the present invention, and evaporates compared to the conventional adsorption refrigeration system consisting of a set of two tanks, an evaporator and a condenser.

For this reason, even if the amount of heat of the heat medium supplied to the adsorber is insufficient and the adsorbent is not sufficiently regenerated, even if the adsorbent adsorbed amount decreases, the operation control of the compressor controls the inside of the evaporator. Since the refrigerant vapor is fed to the condenser, the pressure inside the evaporator is kept constant, and the rise in pressure inside the evaporator makes it difficult for the refrigerant to evaporate, suppressing the generation of heat of vaporization and increasing the temperature of the cold. The situation of doing does not occur. Therefore, it is possible to prevent a decrease in the refrigerating capacity due to insufficient regeneration of the adsorbent.

  Further, in order to compensate for the shortage of the heat source for regeneration, there is no need to provide a separate heat source device for heating the heat medium, and energy consumption can be saved. The compressor may be operated when the amount of heat of the heat medium supplied to the adsorber is insufficient, and the compressor can be stopped as long as the refrigerating capacity is satisfied, and energy consumption is saved. Can be

  Furthermore, in a normal adsorption refrigerator, the switching timing of the two tank adsorbers is determined at a time interval (about 5 to 20 minutes) with a sufficient adsorbent adsorption capacity in order to stabilize the cold water temperature. However, in the present adsorption refrigeration system, since the compressor is operated in combination, it is possible to lengthen the switching time interval. By doing so, it is possible to prevent loss of precooling / preheating energy consumption at the time of switching, and to extend the life of the equipment.

[First embodiment]
The first embodiment of the present invention will be described in detail below with reference to FIG.

  As shown in FIG. 1, the adsorption refrigeration system 1A according to the first embodiment includes a set of two adsorbers 2a and 2b that contain an adsorbent and function as a refrigerant adsorption tank or a desorption tank. An evaporator 3 having a flow path that can communicate with the adsorbers 2a and 2b, a flow path that can communicate with each of the adsorbers 2a and 2b, and a flow path for supplying condensed refrigerant to the evaporator 3 9 is a closed system including a condenser 4 with 9. A first valve 5 and a second valve 6 are interposed in the flow path between the evaporator 3 and the adsorbers 2a and 2b, respectively, and the flow path between the condenser 4 and the adsorbers 2a and 2b. A third valve 7 and a fourth valve 8 are interposed in each. The adsorbers 2a and 2b respectively adsorb the adsorbent by the regeneration flow path 10 through which the adsorbent regeneration heat medium flows to desorb the adsorbed refrigerant by heating the adsorbent during the regeneration (desorption) of the adsorbent. A cooling flow path 11 through which cooling water for cooling the adsorbent that sometimes cools the adsorbent and promotes adsorption of the refrigerant is provided. Further, the evaporator 3 is provided with a heat exchanger 12 through which a refrigerant such as cold water flows, and the refrigerant in the heat exchanger 12 is cooled by the heat of vaporization accompanying the evaporation of the refrigerant in the evaporator 3. Is manufactured. On the other hand, the condenser 4 is provided with a heat exchanger 13 through which cooling water produced by a cooling tower or the like flows, and the heat exchanger 13 comes into contact with the refrigerant vapor in the condenser 4 to thereby generate refrigerant vapor. To cold water.

  In this adsorption refrigeration system 1A, one adsorber 2a functions as an adsorption tank, the other adsorber 2b functions as a desorption tank, the first valve 5 is closed, and the second valve 6 is opened. 3 and one adsorber 2a are communicated, the third valve 7 is opened, the fourth valve 8 is closed and the other adsorber 2b and the condenser 4 are communicated, and one adsorber 2a is The first adsorber 2b functions as an adsorbing tank, and the first valve 5 is opened and the second valve 6 is closed to allow the evaporator 3 and the other adsorber 2b to communicate with each other. The operation is performed so that the operation mode in which the three valves 7 are closed and the fourth valve 8 is opened and the one adsorber 2a and the condenser 4 are communicated with each other is alternately switched.

  Further, in the first embodiment, a flow path 20 for taking out a part of the refrigerant vapor evaporated by the evaporator 3 and introducing it into the condenser 4 is formed, and the refrigerant vapor flowing in the middle of the flow path 20 is compressed. A compressor 21 is disposed. Further, valves 22 and 23 are provided in the vicinity of the evaporator 3 and the condenser 4 in the flow path 20, respectively.

  In the adsorption refrigeration system 1A, the refrigerant compressed by the operation control of the compressor 21 can be supplied to the condenser 4 when the amount of heat of the heat medium supplied to the adsorber 2a or 2b is insufficient. ing.

  Therefore, since the heat quantity of the heat medium flowing through the regeneration channel 10 is insufficient and the adsorbent built in the adsorber functioning as the desorption tank is not sufficiently regenerated, the adsorber functioning as the adsorption tank is used. Even when the adsorption amount of the built-in adsorbent decreases, the refrigerant vapor in the evaporator 3 is sent to the condenser 4 through the flow path 20 by the operation control of the compressor 21, so that the evaporation The pressure rise in the vessel 3 is suppressed. As a result, it is possible to prevent a situation in which the pressure in the evaporator 3 rises and the refrigerant hardly evaporates, the generation of heat of vaporization is suppressed, and the temperature of the cold heat rises. As a result, it is possible to prevent a decrease in the refrigerating capacity of the adsorbent.

  Further, in order to compensate for the shortage of the heat source for regeneration, it is not necessary to provide a separate heat source device for heating the heat medium, and energy consumption for operating the heat source device can be saved. The compressor 21 can be operated when the amount of heat of the heat medium supplied to the adsorber is insufficient, and the compressor 21 can be stopped as long as the refrigerating capacity is satisfied. Can save labor.

  Furthermore, since the refrigerant taken out from the evaporator 3 is compressed by the compressor 21 and supplied to the condenser 4, the temperature of the refrigerant rises as a result of this compression, so that the condensation efficiency in the condenser 4 is improved. From such a viewpoint, even when the heat quantity of the heat medium supplied to the adsorbers 2a and 2b is satisfied, the compressed refrigerant is supplied to the condenser 4 by controlling the operation of the compressor 21, and the refrigerating capacity is improved. It is also possible to improve.

  On the other hand, the switching of the operation mode is usually performed by switching the adsorbers 2a and 2b of the two tanks and the valves 5 to 8 at a time interval (about 5 to 20 minutes) with a sufficient adsorbent adsorption capacity. Although the open / close state is controlled, in the present adsorption refrigeration system 1A, the refrigerant of the evaporator 3 can be supplied to the condenser 4, so that it can be longer than the normal time interval. As a result, energy loss for pre-cooling / pre-heating at the time of switching the adsorbent can be reduced, the thermal efficiency can be improved, and the life of the system can be extended. A specific operation mode switching time interval can be approximately 10 minutes to 30 minutes.

  As described above, the compressor 21 is operated when the amount of heat of the heat medium supplied to the adsorbers 2a and 2b is insufficient. Therefore, the evaporator 3 has a pressure gauge (not shown) for detecting the vapor pressure in the evaporator 3 in order to determine whether or not the heat quantity of the heat medium supplied to the adsorbers 2a and 2b is insufficient. And a thermometer (not shown) for detecting the temperature of the refrigerant (water) accumulated in the evaporator 3 is preferably installed. Based on the pressure detected by the pressure gauge, the lack of cooling capacity can be compensated by controlling the operation of the compressor 21 so as to be equal to or lower than a predetermined pressure corresponding to the refrigerant temperature detected by the thermometer. The pressure in the evaporator 3 is preferably such that the refrigerant temperature is 1.0 kPa or less at 7 ° C. and 2.3 kPa or less (absolute pressure) at 20 ° C., for example.

  The compressor 21 is preferably one that can be controlled in rotation speed by an inverter, and is controlled to a predetermined rotation speed according to the pressure in the evaporator 3. Further, valves 22 and 23 are respectively provided on the suction side and the discharge side of the compressor 21, and the flow rate and pressure of the flow path 20 are controlled by adjusting the opening degree of each valve 22 and 23.

  The compressor 21 may be of various types such as a roots type (rotary type), a reciprocating type, a screw type, a scroll type, and a turbo type. In particular, by using the roots compressor, the system can be reduced in size and power can be saved.

  By the way, it is preferable that the refrigerant circulating through the adsorbers 2a and 2b, the evaporator 3, the condenser 4 and the flow path 20 is a natural refrigerant such as water, ammonia and hydrocarbons. Desirably water.

  The heat medium supplied to the adsorbers 2a and 2b is preferably heated using exhaust heat from a boiler, an incinerator, an engine, or solar heat.

  The cooling water supplied to the adsorbers 2a and 2b and the cooling water supplied to the condenser 4 may be supplied from different cooling devices, but as shown in FIG. The cooling water supplied to the adsorbers 2a and 2b and the cooling water supplied to the condenser 4 are preferably circulated.

[Second embodiment]
As shown in FIG. 2, the adsorption refrigeration system 1 </ b> B according to the second embodiment forms a flow path 20 as compared with the adsorption refrigeration system 1 </ b> A according to the first embodiment. In place of the configuration in which the compressor 21 is disposed in the middle, a flow path 31 that can communicate with the condenser 4 via the valve 33 is provided, and a flow path 32 that supplies condensed refrigerant to the evaporator 3 is provided. The second condenser 30 is disposed, and a second compressor 34 that compresses the circulating refrigerant is disposed in the middle of the flow path 31 that connects the condenser 4 and the second condenser 30. The heat medium supplied to the devices 2a and 2b travels around the heat exchanger 36 in the second condenser 30 to form a flow path 35 that is supplied to the adsorbers 2a and 2b, thereby the adsorbers 2a and 2b. To prevent the refrigerating capacity from being lowered when the amount of heat supplied to the heating medium is insufficient It is obtained by the.

  Specifically, the refrigerant compressed by the operation control of the second compressor 34 can be supplied to the second condenser 30 when the amount of heat of the heat medium supplied to the adsorbers 2a and 2b is insufficient.

  In this way, by making the condenser into two stages, the refrigerant vapor in the first stage condenser 4 is pressurized by the second compressor 34 and supplied to the second condenser 30 in the second stage, Since the temperature of the refrigerant rises as the second compressor 34 is pressurized, the heat medium around the heat exchanger 36 in the second condenser 30 is heated and the regeneration of the adsorbent is promoted, resulting in a decrease in the refrigerating capacity. Can be prevented.

  The operation of the second compressor 34 and the circulation of the heat medium to the heat exchanger 36 are started on the inlet side of the regeneration channel 10 through which the heat medium flows in the adsorbers 2a and 2b. A thermometer (not shown) for detecting this temperature is provided, and the detected temperature can be set to a timing lower than 60 ° C. Even if the heat quantity of the heat medium supplied to the adsorbers 2a and 2b is satisfied, the operation of the second compressor 34 and the circulation of the heat medium to the heat exchanger 36 are performed to improve the refrigerating capacity. You can also plan.

While forming the flow path 20, the compressor 21 which compresses the refrigerant | coolant which distribute | circulates in the middle of this flow path 20, and the flow path 31 which can be connected with the condenser 4 are provided, and the condensed refrigerant | coolant is evaporator A second compressor 30 having a flow path 32 to be fed to the compressor 3 and compressing the refrigerant flowing in the middle of the flow path connecting the condenser 4 and the second condenser 30. 34, and a heat medium supplied to the adsorber forms a flow path 35 to be supplied to the adsorber around the heat exchanger 36 in the second condenser 30, and the adsorber 2a. When the amount of heat of the heat medium supplied to 2b is insufficient, the compressor 21 and / or the second compressor 3 Is a refrigerant compressed by the operation control of those can be supplied to the condenser 4 and / or the second condenser 30.

  In this way, by combining the systems of the first embodiment and the second embodiment, each system can be selectively operated, and both systems can be operated simultaneously. In particular, when both systems are used in combination, the refrigerating capacity is improved in each stage by the synergistic effect of the improvement of the evaporation efficiency in the evaporator 3 and the improvement of the regeneration efficiency of the adsorbent.
