Technical Field

[0001] The utility model relates to the field of refrigeration equipment, and particularly to a new type of steam cycle jet pump refrigerator. Background Art

[0002] In the field of refrigeration technology, traditional refrigeration systems generally use the method of directly compressing refrigerants by compressors to achieve cyclic refrigeration. This technical path has been quite mature after long-term development and is widely used in various refrigeration scenarios. However, with the continuous improvement of society's requirements for energy efficiency, environmental friendliness, and equipment operation stability, traditional refrigeration systems have gradually revealed their limitations in terms of energy efficiency, noise control, and system complexity.

[0003] Specifically, the traditional compressor-driven refrigeration system has the following deficiencies: First, the energy efficiency needs to be improved. The compressor consumes a large amount of energy during the compression of refrigerants and may generate unnecessary energy losses due to mechanical friction. Second, the noise problem. The mechanical vibration and airflow noise generated during the operation of the compressor have a certain impact on the working environment and user experience. Third, the system complexity. Traditional refrigeration systems often require multiple components and complex control logics to ensure the refrigeration effect, increasing the maintenance difficulty and cost of the system.

[0017] More preferably, the diameter of the end of the diffuser pipe connected to the mixing chamber is smaller than the diameter of the end connected to the condenser.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present utility model provides a novel steam cycle jet pump refrigerating machine, which has the following beneficial effects:

[0020] High efficiency and energy saving:

[0021] The high-pressure steam provided by the steam compressor generates a jet effect through the jet pump, effectively sucking in and accelerating the low-temperature and low-pressure fluid in the evaporator, and realizing an efficient heat exchange process. This process reduces energy loss and improves the refrigeration efficiency compared with the traditional method of directly compressing the refrigerant by a compressor.

[0022] The design of the conical nozzle enhances the jet effect, makes the fluid mixing more sufficient, and further improves the heat exchange efficiency.

[0023] The introduction of the circulating heat pump reduces the dependence on external energy by recovering the waste heat in the system, and further improves the energy efficiency ratio of the system.

[0024] Compact structure and small floor area:

[0025] By integrating core components such as a steam compressor, a condenser, an evaporator, a jet pump, a mixing chamber, and a diffuser tube, the refrigerator achieves a compact design of the refrigeration system. Compared with traditional refrigeration systems, it occupies less floor space and is convenient for installation and maintenance.

[0026] Stable operation and low noise:

[0027] The working principle of the jet pump avoids the noise and vibration generated by traditional compressors due to mechanical friction, making the entire refrigeration system operate more smoothly and significantly reducing the noise level.

[0028] The setting of the vapor-liquid separator effectively prevents the vapor bubbles in the condensate from entering the subsequent pipelines and equipment, ensuring the stable operation of the system.

[0029] Flexible adjustment and strong adaptability:

[0030] By adjusting the output pressure of the steam compressor and the working state of the jet pump, the refrigerating capacity and refrigerating temperature of the refrigeration system can be flexibly controlled to meet the refrigeration requirements in different scenarios.

[0031] The design of the conical diffuser tube makes the fluid more stable during the process of decelerating and boosting pressure, enhancing the adaptability of the system to changes in fluid parameters.

[0032] Improve the mixing effect and enhance heat exchange:

[0033] The driving motor and conveying paddle installed in the mixing chamber further enhance the mixing effect between fluids through the stirring action of the propeller blades, making the heat exchange more sufficient and improving the overall performance of the system.

[0034] Reduce maintenance costs and extend service life:

[0035] Due to the relatively simple working principle of the jet pump and the avoidance of complex mechanical structures in traditional compressors, the number of failure points and maintenance difficulties are reduced, and the maintenance costs are lowered.

[0036] At the same time, the stable operation and efficient heat exchange of the system also reduce the wear and corrosion of components, extending the service life of the equipment.

[0037] In summary, the new steam cycle jet pump refrigerator shows significant beneficial effects in terms of high efficiency and energy conservation, compact structure, stable operation, flexible adjustment, improved mixing effect, and reduced maintenance costs, providing new ideas and directions for the development of refrigeration technology.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Please refer to Figures 1 - 3 , a new type of steam cycle jet pump refrigerating machine of the present utility model includes the following components:

[0044] Steam compressor 1: used to provide high-pressure steam;

[0045] Condenser 5: used to condense steam into liquid;

[0046] Evaporator 2: used to absorb heat and generate low-temperature and low-pressure steam or fluid;

[0047] Jet pump 3: having an input end and an output end, the input end is provided with an input pipe 8, and the steam compressor 1 is communicated with the input pipe 8 through a pipeline;

[0048] Mixing chamber 4: the output end of the jet pump 3 is communicated with the mixing chamber 4 through a pipeline, a nozzle 11 is arranged on the pipeline at the output end of the jet pump 3, the evaporator 2 is communicated with the mixing chamber 4 through a pipeline, used to mix the high-speed fluid and the low-temperature and low-pressure fluid from the evaporator 2, the mixing chamber 4 is communicated with the condenser 5 through a diffuser pipe 9, the diffuser pipe 9 is of a conical structure, and the diffuser pipe 9 is used to decelerate and boost the mixed fluid in the mixing chamber 4 and then send it into the condenser 5.

[0049] In the preferred scheme of the above new type of steam cycle jet pump 3 refrigerating machine:

[0050] Integration of the vapor-liquid separator 6 and the circulating heat pump 7: Connect the vapor-liquid separator 6 with the condenser 5, the evaporator 2 and the circulating heat pump 7 through pipelines, which not only improves the integration degree of the system, but also realizes the efficient recovery and utilization of heat.

[0051] Design of the drive motor 10 and the conveying paddle 12 of the mixing chamber 4: The introduction of the drive motor 10 and the propeller blades enhances the mixing effect of the fluid in the mixing chamber 4, improves the heat exchange efficiency, and thus further enhances the performance of the refrigerator.

[0052] Conical structure design of the nozzle 11: The design of the conical nozzle 11 optimizes the jet effect, making the fluid more efficient during the suction and acceleration processes, which helps to improve the overall performance of the system.

[0053] Layout of the mixing chamber 4, the jet pump 3, and the evaporator 2: The jet pump 3 is connected to the upper end of the mixing chamber 4 through a pipeline, and the evaporator 2 is connected to the bottom end of the mixing chamber 4 through a pipeline. This layout is conducive to the smooth flow and efficient mixing of the fluid.

[0054] Conical design of the diffuser tube 9: The diameter of the end of the diffuser tube 9 connected to the mixing chamber 4 is smaller than the diameter of the end connected to the condenser 5. This design helps the fluid maintain a relatively high pressure during the deceleration process, so as to enter the condenser 5 more stably for condensation.

[0055] The present utility model describes a new type of steam cycle jet pump 3 refrigerator, whose working principle is mainly based on thermodynamic processes such as steam compression, condensation, evaporation, and jet effect. Through the coordinated operation of a series of precisely designed components, an efficient refrigeration effect is achieved. The following is a detailed summary of the working principle of this refrigerator:

[0056] Steam compressor 1: As the power source of the system, the steam compressor 1 compresses the steam to a high-pressure state. During this process, the internal energy of the steam increases and the temperature rises, providing the necessary energy for the subsequent heat exchange process.

[0057] Input of high-pressure steam: The compressed high-pressure steam is transported to the input end of the jet pump 3 through a pipeline. The jet pump 3 utilizes the kinetic energy of the high-pressure steam to generate a high-speed jet through the nozzle 11.

[0058] Jet pump 3 and nozzle 11: The nozzle 11 of the jet pump 3 is designed in a special shape (such as conical) to ensure that the steam accelerates in the nozzle 11 and forms a high-speed jet. The diameter of the output end of the nozzle 11 is smaller than that of the input end, so that the speed of the steam increases sharply when flowing out of the nozzle 11, and a low-pressure area is formed at the outlet of the nozzle 11.

[0059] Suction of low-temperature and low-pressure fluid: The low-temperature and low-pressure steam or fluid generated in the evaporator 2 is sucked into the mixing chamber 4 through a pipeline. Due to the low-pressure effect at the outlet of the nozzle 11 of the jet pump 3, these low-temperature and low-pressure fluids are effectively sucked in and mixed with the high-speed steam.

[0060] Mixing chamber 4: Inside the mixing chamber 4, high-speed steam and low-temperature and low-pressure fluid undergo intense mixing and heat exchange. The kinetic energy of the steam is converted into the internal energy of the fluid. At the same time, the temperature of the steam decreases while the temperature of the fluid increases. During this process, the heat released by the steam is absorbed by the fluid, thereby achieving a refrigeration effect.

[0061] Diffuser 9: The mixed fluid enters the condenser 5 through the diffuser 9. The diffuser 9 is designed as a conical structure, and the pipe diameter gradually increases from one end of the mixing chamber 4 to one end of the condenser 5. This design enables the fluid to gradually slow down and the pressure to gradually increase during the flow process, which helps the fluid enter the condenser 5 smoothly and efficiently.

[0062] Condenser 5: In the condenser 5, the mixed fluid releases heat and condenses into a liquid. The heat released during the condensation process can be carried away by a cooling medium (such as water or air), thereby achieving heat transfer and discharge.

[0063] Refrigeration cycle: The condensed liquid can be further processed through other components in the system (such as a vapor-liquid separator 6, a liquid storage tank, etc.) and finally return to the evaporator 2 to be re-evaporated to form low-temperature and low-pressure steam or fluid, thus completing the entire refrigeration cycle.

[0064] In summary, this new type of steam-cycle jet pump 3 refrigeration machine provides power through the steam compressor 1, generates high-speed jets through the jet pump 3, realizes heat exchange in the mixing chamber 4, and completes the processes of fluid deceleration, pressure increase, and condensation through the diffuser 9 and the condenser 5, achieving an efficient and stable refrigeration effect.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
