Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically a refrigeration water cooling load detection device. Background Technology

[0002] Currently, the operating status of the refrigeration system in a typical refrigeration room is adjusted based on real-time feedback data from sensors. The overall performance of the refrigeration system is affected by many factors, among which the cooling load has a significant impact on the energy efficiency of the refrigeration system. A reasonable operating strategy for the refrigeration system based on the cooling load can improve the operating performance of the refrigeration system.

[0003] Currently, most refrigeration system cooling load detection is performed using real-time data from sensors. However, since the entire refrigeration system is quite large and requires many sensors, there are numerous power supply lines for these sensors. Furthermore, the tangled nature of these lines makes it difficult to detect a faulty sensor, posing a significant challenge to maintaining the refrigeration system's operation.

[0004] To address the aforementioned issues, we propose a refrigeration water cooling load detection device, which improves upon the shortcomings of existing technologies. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a refrigeration water cooling load detection device. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution:

[0006] This utility model is a refrigeration water cooling load detection device, including a refrigeration system. The feature is that a microprocessor is installed on the pipes of the refrigeration system, and the microprocessor includes a microcontroller, a detection module and a power module.

[0007] The detection module is used to detect parameters of the operating conditions inside the pipeline and transmit the data to the signal processing module of the microcontroller via wires. The detection module includes a pressure sensor, a temperature sensor, a differential pressure sensor, and a flow sensor.

[0008] The microcontroller includes a display screen, a communication module, control buttons, a storage module, and a signal processing module. The signal processing module decodes the data from the detection module, displays it on the display screen, and stores it in the storage module. The communication module can transmit the data in the storage module to a remote monitoring terminal via a wireless signal.

[0009] The power module extends through the pipes of the refrigeration system and is equipped with a drive end. The flow conditions inside the pipes drive the drive end to rotate and generate electricity, which is then supplied to the microcontroller and the detection module.

[0010] Furthermore, the power module includes a generator and a battery. The generator is located on one side of the pipeline, and its shaft extends through the pipeline and has a drive end. A regulator is mounted on the generator, and the generator is connected to the battery via the regulator. The battery supplies power to the microcontroller and the detection module.

[0011] Furthermore, a sealing adapter is provided on the pipeline, and the generator shaft is connected to the drive end through the sealing adapter.

[0012] Furthermore, the generator's rotating shaft is connected to the output shaft of the speed increaser, and the speed increaser's input shaft passes through the pipe and is connected to the drive end.

[0013] Furthermore, the drive end is a water turbine.

[0014] Furthermore, the drive end is a axial-flow turbine.

[0015] Furthermore, the driving ends of the detection module and the power module are located inside the main pipe of the pipeline.

[0016] Furthermore, the pipeline is provided with a branch pipe for power generation, the drive end of the power module is located inside the branch pipe, and a valve is provided on the branch pipe.

[0017] The beneficial effects of this utility model are:

[0018] 1. By segmenting the detection modules, the detection modules transmit data from numerous sensors in each segment together, which is then displayed on the screen on the microcontroller. The remote monitoring terminal integrates the received data to calculate the cooling load and adjusts the refrigeration system's operating strategy in a timely manner. In addition, inspectors can view the current data on the screen and check the data using their own equipment. They can also review the overall data through the remote monitoring terminal, greatly improving the efficiency of refrigeration system maintenance.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Example 1

[0030] like Figure 1 As shown, a refrigeration water cooling load detection device includes a refrigeration system, and a microprocessor is installed on the pipes of the refrigeration system. The microprocessor includes a microcontroller 7, a detection module and a power module 2.

[0031] The detection module is used to detect parameters of the operating conditions inside the pipeline and transmit the data to the signal processing module 71 of the microcontroller 7 via wires. The detection module includes a pressure sensor 3, a temperature sensor 4, a differential pressure sensor 5, and a flow sensor 6.

[0032] Pressure sensor 3 is used to detect the pressure within the pipeline. Temperature sensor 4 is used to detect the temperature within the pipeline, such as saturated evaporation temperature, saturated condensation temperature, subcooling, and superheat. Differential pressure sensor 5 can detect the pressure difference between the inlet and outlet. Flow sensor 6 can detect the flow rate within the pipeline. Other sensors or detection devices can also be installed as needed, such as ammeters and voltmeters to monitor compressor operation, and to detect parameters such as full-load line current, minimum-load line current, real-time phase current, and full-load phase current.

[0033] The microcontroller 7 includes a display screen 72, a communication module 73, control buttons 74, a storage module 75, and a signal processing module 71. The signal processing module 71 decodes the data from the detection module, displays it on the display screen 72, and stores it in the storage module 75. The communication module 73 can transmit the data in the storage module 75 to the remote monitoring terminal 76 via wireless signals. The communication module 73 includes units that can transmit data wirelessly, such as Bluetooth, Ethernet, and WiFi, meaning it can use any known network communication protocol to establish a communication connection and interact with the remote monitoring terminal 76.

[0034] Furthermore, the microcontroller 7 can also be equipped with a wired interface. During inspections, the inspector can connect to the communication module 73 via Bluetooth or WiFi to access data stored in the storage module 75, or connect via a data cable to the wired interface to access data stored in the storage module 75. Data can also be directly displayed on the display screen 72 using the control buttons 74 on the microcontroller 7. Outside of inspections, the remote monitoring terminal 76 connects wirelessly to the communication module 73 to read or write relevant data. The storage module 75 stores software programs and data. The microcontroller 7 executes data processing and other functions by running the software programs or data stored in the storage module 75.

[0035] The power module 2 runs through the pipes of the refrigeration system and is equipped with a drive end. The flow conditions in the pipes drive the drive end to rotate and generate electricity, which is then supplied to the microcontroller 7 and the detection module.

[0036] Example 2

[0037] See Figure 5-6To facilitate the storage of generated electricity, based on Embodiment 1, the power module 2 includes a generator 21 and a battery 23. The generator 21 is located on one side of the pipeline, and its shaft extends through the pipeline, with a drive end provided. A regulator is mounted on the generator 21, and the generator 21 is connected to the battery 23 via the regulator. The battery 23 supplies power to the microcontroller 7 and the detection module. The generator 21 is connected to the regulator via wires, and the regulator is connected to the battery 23 via wires, thereby storing the electricity generated by the generator 21 in the battery 23. The battery 23 is also connected to the microcontroller 7 and the detection module via wires, supplying power to them. In this embodiment, the generator 21 is located at a corner of the pipeline.

[0038] Example 3

[0039] See Figure 5-6 To ensure the airtightness of the pipeline, based on Example 2, a sealing adapter 24 is provided on the pipeline, and the shaft of the generator 21 is connected to the drive end through the sealing adapter 24.

[0040] Example 4

[0041] See Figure 5-6 In order to increase the power generation of generator 21, based on embodiment 2, the shaft of generator 21 is connected to the output shaft of speed increaser 22, and the input shaft of speed increaser 22 passes through the pipe and is connected to the drive end. Increasing the speed increaser 22 can change the transmission ratio and realize the change of speed and torque between the drive end and generator 21.

[0042] Example 5

[0043] See Figure 6 Based on Example 1, the driving end is a water turbine 25. The water turbine 25 is driven to rotate by the working conditions in the pipeline, and drives the shaft of the generator 21 to rotate to generate electricity.

[0044] Example 6

[0045] See Figure 6 To adapt to the flow conditions within the pipeline, based on Example 5, the drive end is a cross-flow turbine 25. The cross-flow turbine 25 reduces hydraulic losses within the flow channel (pipeline), has high efficiency, and a small diameter. A suitable turbine 25 can be selected for high-head refrigeration systems. The cross-flow turbine 25 is a reaction turbine 25. For head ranges exceeding 30m, axial-flow, oblique-flow, or mixed-flow reaction turbines 25 can be used, and their structures will require corresponding modifications.

[0046] Example 7

[0047] See Figure 2 and Figure 7The drive ends of the detection module and the power module 2 are located inside the main pipeline 1 of the pipeline.

[0048] Example 8

[0049] See Figure 3 and Figure 7 To avoid hydraulic loss, a branch pipe 101 for power generation is provided in the pipeline, and the drive end of the power module 2 is located in the branch pipe 101. A valve 102 is provided on the branch pipe 101. When the power supply is sufficient or when the refrigeration system is under maintenance, the branch pipe 101 can be closed by the valve 102 to shut down the generator 21 and stop power generation. This also ensures that the operation of the refrigeration system is not delayed when the generator 21 is under maintenance.

[0050] See Figure 4 Detection modules can also be installed on the cold water inlet pipe 103 and hot water outlet pipe 104 of the evaporator 105. Alternatively, detection modules can be installed on the pipes of the refrigeration system according to actual needs. The number and location of the power modules 2 can be set according to the number and location of the detection modules.

[0051] The principle and advantages of this utility model:

[0052] The operating conditions drive the water turbine 25 inside the pipeline to rotate, thereby driving the generator 21 outside the pipeline to work. The power generated by the generator 21 is stored in the battery 23. The battery 23 supplies power to the surrounding microcontroller 7 and detection module, maintaining the normal operation of the microcontroller 7 and detection module. The detection module sends the parameters of the pipeline's industrial control to the microcontroller 7. After being decoded by the signal processing module 71, the parameters are output on the display screen 72 and sent to the remote monitoring terminal 76 through the communication module 73 for calculating the cooling load. When inspectors are inspecting the machine room, they can interact with the microcontroller 7 and read the data for review.

[0053] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
