下面对本实用新型的实施例作详细说明，本实施例在以本实用新型技术方案为前提下进行实施，给出了详细的实施方式和具体的操作过程，但本实用新型的保护范围不限于下述的实施例。The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.
实施例1Example 1
本实施例提供了一种带有喷射调压装置的吸收式制冷系统，具有如图1所示的结构，包括发生器1、冷凝器2、蒸发器4、吸收器6和设于吸收器6内的喷射器7，其中：This embodiment provides an absorption refrigeration system with a spray pressure regulating device, which has a structure as shown in Figure 1, including a generator 1, a condenser 2, an evaporator 4, an absorber 6 and an absorber 6 Injector 7 within which:
所述发生器1的气体出口连接至冷凝器2的气体入口，冷凝器2的溶液出口通过一减压阀3连接至蒸发器4的溶液入口，蒸发器4的气体出口连接至喷射器7的气体入口，发生器1的溶液出口通过另一减压阀8连接至喷射器7的溶液入口，喷射器7的喷射口位于吸收器6内，吸收器6的溶液出口通过循环泵5连接至蒸发器4的入口；The gas outlet of the generator 1 is connected to the gas inlet of the condenser 2, the solution outlet of the condenser 2 is connected to the solution inlet of the evaporator 4 through a pressure reducing valve 3, and the gas outlet of the evaporator 4 is connected to the injector 7 The gas inlet, the solution outlet of the generator 1 are connected to the solution inlet of the injector 7 through another pressure reducing valve 8, the injection port of the injector 7 is located in the absorber 6, and the solution outlet of the absorber 6 is connected to the evaporator through a circulation pump 5 The entrance of device 4;
所述喷射器7的蒸汽入口位于喷射器7的侧面，其溶液入口位于喷射器7的顶部，其喷射口朝下面对吸收器6的底部，所述发生器1、冷凝器2、蒸发器4、吸收器6和喷射器7之间均通过管道连接。The steam inlet of the injector 7 is positioned at the side of the injector 7, and its solution inlet is positioned at the top of the injector 7, and its injection port faces down to the bottom of the absorber 6, and the generator 1, the condenser 2, the evaporator 4. Both the absorber 6 and the injector 7 are connected by pipelines.
工作时，发生器1内的稀溶液经加热后，稀溶液中的制冷剂蒸发成气态进入冷凝器2内，在冷凝器2中气态制冷剂经降温后变成液态，经减压阀减压后进入蒸发器4，在蒸发器4中液态制冷剂因为压力的降低气化吸热，并产生低温冷量送至应用端。由于蒸发温度与蒸发器4中的压力成正比，气态制冷剂经喷射器7的气体引流入口进入吸收器6，同时发生器1内的稀溶液中制冷剂蒸发后的浓溶液经减压阀减压后，通过喷射器7进入吸收器6，将气态制冷剂吸收，吸收后获得的稀溶液通过循环泵5再次送入发生器1中，完成循环。本实用新型的关键点为喷射器7的使用，喷射器7设于吸收器6内，由于蒸发压力越小，蒸发温度越低，因此，在喷射器7的作用下，通过流经溶液的喷射引流作用，使蒸发器4中的压力低于吸收器6压力，在保证吸收压力的同时获得更低的蒸发压力，对应蒸发器4内也获得了更低的蒸发温度。在保证系统保持较高吸收/解吸效率的同时获得更低的制冷温度，可以大幅拓宽吸收式制冷系统的实际使用领域和应用范围。When working, after the dilute solution in the generator 1 is heated, the refrigerant in the dilute solution evaporates into a gaseous state and enters the condenser 2. In the condenser 2, the gaseous refrigerant becomes liquid after cooling down, and is decompressed by the pressure reducing valve. After entering the evaporator 4, the liquid refrigerant in the evaporator 4 gasifies and absorbs heat due to the decrease in pressure, and generates low-temperature cooling capacity and sends it to the application end. Since the evaporation temperature is directly proportional to the pressure in the evaporator 4, the gaseous refrigerant enters the absorber 6 through the gas introduction inlet of the ejector 7, and at the same time, the concentrated solution of the refrigerant in the dilute solution in the generator 1 is reduced by the pressure reducing valve. After compression, it enters the absorber 6 through the ejector 7 to absorb the gaseous refrigerant, and the dilute solution obtained after absorption is sent to the generator 1 again through the circulation pump 5 to complete the cycle. The key point of the utility model is the use of the injector 7, which is arranged in the absorber 6. Since the evaporation pressure is smaller, the evaporation temperature is lower. The diversion effect makes the pressure in the evaporator 4 lower than that of the absorber 6 , and obtains a lower evaporation pressure while ensuring the absorption pressure, corresponding to a lower evaporation temperature in the evaporator 4 . Obtaining a lower refrigeration temperature while maintaining a high absorption/desorption efficiency of the system can greatly expand the practical use field and application range of the absorption refrigeration system.
