The absorption refrigeration system 100 is filled with a working medium pair consisting of a high-boiling absorbent and a low-boiling refrigerant. For convenience of description, the absorbent is water, and the refrigerant is lithium bromide. It will be appreciated by those skilled in the art that the absorption refrigeration system 100 of the present application can be adapted for use with various types of working substance pairs of high boiling point absorbents and low boiling point refrigerants.

The absorption refrigeration system 100 is filled with a lithium bromide solution. The lithium bromide solution comprises water and lithium bromide. The arrows in fig. 1 indicate the direction of the fluid (i.e., the lithium bromide solution) when the absorption refrigeration system 100 is operating. The flow of lithium bromide solution in absorption refrigeration system 100 when absorption refrigeration system 100 is in operation is described as follows:

in the generator 112, a working heat source (e.g., municipal heat supply, not shown) in the generator 112 heats the lithium bromide solution (dilute lithium bromide solution), causing water in the lithium bromide solution to evaporate and flow out of the generating absorption system outlet 1022. The water vapor flows into the condenser 104 through the refrigeration system first passage 132. In the condenser 104, the water vapor exchanges heat with an ambient medium (the arrows entering the condenser 104 and exiting the condenser 104 in fig. 1 indicate the direction of the ambient medium, e.g., cooling water). The water vapor releases heat, is liquefied and then is condensed into liquid water. Liquid water exits the condenser 104 through the condenser outlet 1042 and flows into the evaporator 108 through the heat exchange system connection 136. In the evaporator 108, the liquid water is heat-exchanged with a cooled medium (the arrows entering the evaporator 108 and exiting the evaporator 108 in fig. 1 indicate the direction of the cooled medium, such as chilled water). The liquid water absorbs heat, is vaporized and then becomes gas, and becomes water vapor. The water vapor exits the evaporator 108 through the evaporator outlet 1082 and flows into the absorber 114 through the refrigeration system second passage 134. The concentrated lithium bromide solution (lithium bromide and non-evaporated water) after the process (i.e., water is evaporated) in generator 112 flows into absorber 114 through the second path 124 of the generation absorption system. In the absorber 114, the concentrated lithium bromide solution from the generator 112 is mixed with the water vapor from the evaporator 108 to recover a dilute lithium bromide solution. A cooling device (not shown) is provided in the absorber 114 to reduce the temperature of the concentrated lithium bromide solution from the generator 112 and the water vapor from the evaporator 108 in the absorber 114. Because the absorption process (i.e., dilution of the rich solution to the dilute solution) is an exothermic process, reducing the temperature of the solution in the absorber 114 can help speed the absorption process. The dilute lithium bromide solution is then fed into the generator 112 through the generation absorption system first path 122.

In absorption refrigeration system 100, the cycle of generator 112, absorber 114, generating absorption system first pass 122, and generating absorption system second pass 124 is referred to as generating absorption system 102. Wherein the outlet of the absorption generating system 102 is disposed on the generator 112, which becomes the absorption generating system outlet 1022. The inlet of the generating absorption system 102 is disposed on the absorber 114, which is a generating absorption system inlet 1021. The condenser 104, the heat exchange system connection passage 136 and the evaporator 108 are connected to form the heat exchange system 101. The inlet of the heat exchange system 101 is the condenser inlet 1041. The outlet of the heat exchange system 101 is the evaporator outlet 1082. Thus, in other words, the generative absorption system outlet 1022 of the generative absorption system 102 is connected to the inlet of the heat exchange system 101 through the refrigeration system first pass 132. The generating absorption system inlet 1021 of the generating absorption system 102 is connected to the outlet of the heat exchange system 101 through the refrigeration system second pass 134.

There is a liquid flow path in the heat exchange system 101. In the heat exchange system 101, a liquid flow path is formed where the liquid water flows. It will be appreciated that when the absorption refrigeration system 100 is operating, a certain amount of liquid water will be deposited in the condenser 104 at the bottom of the condenser 104, thereby forming a condenser liquid level. When the evaporator 108 is a falling film evaporator and the absorption refrigeration system 100 is operating, a quantity of unevaporated liquid water is also deposited on the bottom of the evaporator 108, forming an evaporator liquid level. Thus, the liquid flow path includes at least the bottom of the condenser 104, the heat exchange system connection passage 136, and the bottom of the evaporator 108.

The absorption refrigeration system 100 also includes a solution passageway 142. One end of the solution path 142 is connected to the absorption generation system 102. That is, one end of the solution passage 142 may be connected to any one of the generator 112, the absorber 114, the generation absorption system first passage 122, and the generation absorption system second passage 124. The other end of the solution passage 142 is connected to the liquid flow path of the heat exchange system 101. That is, the other end of the solution passage 142 can be connected to any point on the liquid flow path. The solution passageway 142 enables liquid in the liquid flow path to flow into the generating absorption system 102 through the solution passageway 142.

In addition, the solution passage 142 can be controllably connected or disconnected. As an example, the solution passage 142 is provided with a switch device 152, and the opening or closing of the switch device 152 can control the connection or disconnection of the solution passage 142 accordingly. As one example, the switching device 152 is a valve.

The absorption refrigeration system 100 also includes a refrigeration detection device 144 and a control device 148. A cold detecting device 144 is installed on the evaporator 108 for detecting the cold supplied from the evaporator 108. The control device 148 is connected in communication with the coldness detection device 144 and the switching device 152. The control device 148 can control the opening or closing of the switch device 152 according to the signal provided by the cold quantity detection device 144, thereby controlling the connection or disconnection of the solution passage 142.

As one example, the evaporator 108 includes a cooled medium inlet pipe 162 and a cooled medium outlet pipe 164 that lead out from the inside of the evaporator. The cooled medium flowing into the evaporator 108 from the cooled medium inlet pipe 162 can be cooled by water inside the evaporator 108. The cooled medium flows out of the evaporator 108 from the cooled medium outlet pipe 164, so that the evaporator 108 supplies cooling energy to the cooled medium. The coldness detection device 144 may be installed on the cooled medium outlet pipe 164 of the evaporator 108 to detect the coldness supplied from the evaporator 108 by detecting the temperature of the cooled medium. When the amount of cold provided by the evaporator 108 is less than the predetermined amount of cold, the control device 148 sends a signal to the switching device 152 to open the switching device 152, thereby communicating with the solution passageway 142. When the amount of cold provided by the evaporator 108 is greater than or equal to the predetermined amount of cold, the control device 148 sends a signal to the switching device 152 to cause the switching device 152 to close, thereby disconnecting the solution path 142.

In conventional absorption refrigeration systems, the amount of heat provided to the operating heat source of the generator 112 is constant. For example, municipal heating provides a certain amount of heat. When the amount of cold provided by the evaporator 108 is less than the predetermined amount of cold, the amount of heat consumed in the generator 112 is correspondingly reduced. However, since the amount of heat provided to the working heat source of the generator 112 is constant, an additional system for consuming the heat of the working heat source is required, thereby ensuring that a certain amount of heat is consumed. However, this method requires another system for consuming heat from the working heat source, and is costly and occupies a large area.

In the absorption refrigeration system 100 of the present application, one end of the solution passage 142 is connected to the absorption generation system 102, and the other end of the solution passage 142 is connected to the liquid flow path of the heat exchange system 101. When the cold quantity provided by the evaporator 108 is less than the predetermined cold quantity, the switching device 152 is opened to communicate with the solution passage 142. At this time, the liquid water in the heat exchange system 101 can flow to the generation absorption system 102 through the solution passage 142. This provides liquid water to the generating absorption system 102 while reducing the liquid evaporated in the evaporator 108. In one aspect, reducing the amount of liquid evaporated in the evaporator 108 can reduce the amount of cooling provided by the evaporator 108, thereby satisfying the need to both reduce the amount of cooling provided. On the other hand, providing liquid water into the generation absorption system 102 ensures that the liquid water absorbs heat provided by the working heat source in the generator 112, thereby ensuring that a sufficient amount of heat from the working heat source is consumed. As the liquid water absorbs heat in the generator 112, the water changes from a liquid state to a gaseous state, and more heat can be consumed as the water undergoes a phase change.

Fig. 2A is a first embodiment using the absorption refrigeration system 100 shown in fig. 1. Fig. 2A is substantially the same as fig. 1, and the description thereof is omitted here. In fig. 2A, one end of the solution passage 142 is connected to the generation absorption system first passage 122 in the generation absorption system 102, and the other end of the solution passage 142 is connected to the evaporator 108 in the heat exchange system 101. Specifically, when the amount of cold supplied from the evaporator 108 is less than the predetermined amount of cold, the switching device 152 is opened, thereby communicating with the solution passage 142. The liquid that is not vaporized in the vaporizer 108 at this time can flow to the absorption system first passage 122 through the solution passage 142. This ensures that the liquid water absorbs heat in the generator 112 to evaporate while reducing the liquid evaporated in the evaporator 108, thereby ensuring consumption of the working heat source in the generator 112.

Fig. 2B is a second embodiment using the absorption refrigeration system 100 shown in fig. 1. Fig. 2B is substantially the same as fig. 1, and the description thereof is omitted here. In fig. 2B, one end of the solution passage 142 is connected to the absorber 114 in the absorption generation system 102, and the other end of the solution passage 142 is connected to the evaporator 108 in the heat exchange system 101. Specifically, when the amount of cold supplied from the evaporator 108 is less than the predetermined amount of cold, the switching device 152 is opened, thereby communicating with the solution passage 142. The unevaporated liquid in the evaporator 108 at this time can flow to the absorber 114 through the solution passage 142. This allows the liquid water to be further cooled in the absorber 114 while reducing the liquid evaporated in the evaporator 108, thereby allowing this portion of the liquid exiting the evaporator 108 to enter the generator 112 at a lower temperature to ensure consumption of the working heat source in the generator 112.

Fig. 2C is a third embodiment using the absorption refrigeration system 100 shown in fig. 1. Fig. 2C is substantially the same as fig. 1, and the description thereof is omitted here. In fig. 2C, one end of the solution passage 142 is connected to the generation absorption system first passage 122 in the generation absorption system 102, and the other end of the solution passage 142 is connected to the heat exchange system connection passage 136 in the heat exchange system 101. Specifically, when the amount of cold supplied from the evaporator 108 is less than the predetermined amount of cold, the switching device 152 is opened, thereby communicating with the solution passage 142. The liquid that does not enter the evaporator 108 at this time can flow to the absorption system first passage 122 through the solution passage 142. This ensures that the liquid water absorbs heat in the generator 112 and evaporates, thereby ensuring consumption of the working heat source in the generator 112, while reducing the liquid entering the evaporator 108.

Fig. 2D is a fourth embodiment using the absorption refrigeration system 100 shown in fig. 1. Fig. 2D is substantially the same as fig. 1, and the description of the same parts is omitted here. In fig. 2D, one end of the solution passage 142 is connected to the absorber 114 in the generation absorption system 102, and the other end of the solution passage 142 is connected to the heat exchange system connection passage 136 in the heat exchange system 101. Specifically, when the amount of cold supplied from the evaporator 108 is less than the predetermined amount of cold, the switching device 152 is opened, thereby communicating with the solution passage 142. The liquid that does not enter the evaporator 108 at this time can flow into the absorber 114 through the solution passage 142. This allows the liquid water to be further cooled in the absorber 114 while reducing the liquid entering the evaporator 108, thereby allowing this portion of the liquid exiting the heat exchange system connection 136 to enter the generator 112 at a lower temperature to ensure consumption of the working heat source in the generator 112.

Fig. 2E shows a fifth embodiment using the absorption refrigeration system 100 shown in fig. 1. FIG. 2E is substantially the same as FIG. 1, and the description thereof is omitted here. In fig. 2E, one end of the solution passage 142 is connected to the generation absorption system second passage 124 in the generation absorption system 102, and the other end of the solution passage 142 is connected to the heat exchange system connection passage 136 in the heat exchange system 101. Specifically, when the amount of cold supplied from the evaporator 108 is less than the predetermined amount of cold, the switching device 152 is opened, thereby communicating with the solution passage 142. The liquid that does not enter the evaporator 108 at this time can flow to the absorption system second passage 124 through the solution passage 142, thereby flowing into the absorber 114. This allows the liquid water to be mixed with the concentrated lithium bromide solution prior to entering the absorber 114 and then further cooled in the absorber 114 while reducing the liquid entering the evaporator 108, thereby allowing the liquid water to be mixed more uniformly with the concentrated lithium bromide solution and allowing the diluted lithium bromide solution, which has been cooled in the absorber 114 after mixing, to enter the generator 112 at a lower temperature to ensure consumption of the operating heat source in the generator 112.

As an example, a driving device (not shown) may be disposed in the first passage 122 of the generation absorption system or the second passage 124 of the generation absorption system to drive the lithium bromide solution to circulate in the generator 112 and the absorber 114.

While only certain features of the application have been illustrated and described herein, many modifications and changes will occur to those skilled in the art.
