Abstract
Description
Technical Field
[0001] This utility model relates to the field of online environmental monitoring technology, and in particular to a low-energy monitoring station for environmental monitoring. Background Technology
[0002] With the development of environmental monitoring technology, online monitoring stations need to operate stably for extended periods, and their internal instruments have strict temperature requirements (typically maintained at 25-30℃). Current technology generally uses air conditioning systems for temperature control, which works by transferring indoor heat to the outdoors through a refrigerant phase change cycle (compression, condensation, throttling, evaporation). However, this approach has significant drawbacks:
[0003] Air conditioning systems rely on the continuous operation of compressors, which need to work at full load for extended periods in extreme high-temperature environments. Taking a typical 1.5 horsepower, energy-efficient air conditioner as an example, its annual power consumption is as high as 6132 kWh (calculated based on an average daily operation of 18 hours), leading to a significant increase in operation and maintenance costs.
[0004] In high-temperature environments, the heat dissipation capacity of the air conditioner's outdoor unit decreases, and the refrigerant condensation efficiency reduces, causing the temperature inside the station building to easily exceed 30°C, affecting the accuracy and lifespan of monitoring instruments. Furthermore, air conditioners rely solely on air convection for heat exchange, resulting in a limited heat dissipation area and making it difficult to achieve rapid and uniform cooling. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a low-energy monitoring station for environmental monitoring, so as to solve the problems in the background art.
[0006] In view of this, the present invention provides a low-energy monitoring station for environmental monitoring, comprising:
[0007] An air-source heat pump temperature control system includes a compressor, a condenser, and cooling water piping. The compressor generates cooling capacity through a refrigerant phase change cycle.
[0008] The station building has embedded cooling pipes in its walls, forming a closed loop.
[0009] The plate heat exchanger is provided with a first heat exchange channel and a second heat exchange channel. The first heat exchange channel is connected to the cooling water pipeline of the air source temperature control system to form a first circulation loop, and the second heat exchange channel is connected to the embedded cooling pipeline of the station building wall to form a second circulation loop.
[0010] The first and second circulation loops achieve cross-type heat exchange through a plate heat exchanger.
[0011] Optionally, the air-source temperature control system further includes:
[0012] The evaporator is located at the compressor outlet.
[0013] An expansion valve connects the condenser and the evaporator.
[0014] Optionally, the cooling water pipe is installed inside the evaporator, and the refrigerant flow channel and the cooling water flow channel form a heat exchange structure.
[0015] Optionally, the embedded cooling pipes in the station building wall are arranged in a reciprocating "bow" shape on the wall.
[0016] Optionally, the plate heat exchanger is coated with a graphene nano-coating, and the graphene nano-coating is applied to the plate contact surface of the plate heat exchanger.
[0017] Optionally, an electronic water pump is installed at the water inlet of the embedded cooling pipe in the station building wall, and the electronic water pump is located on the second circulation loop.
[0018] Optionally, a temperature sensor and a flow regulating valve are also provided at the nodes of the second loop, and the flow regulating valve and the temperature sensor are connected to form a closed-loop control system.
[0019] Optionally, the COP value of the air source temperature control system is 3.2-4.1.
[0020] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:
[0021] 1. This utility model discloses a low-energy-consumption monitoring station for environmental monitoring. Through an air-source heat pump temperature control system, embedded cooling pipes in the station wall indirectly exchange heat via plate heat exchangers, reducing cooling loss. Combined with an electronic water pump and closed-loop flow regulation technology, the system's annual power consumption can be reduced to below 2450 kWh, achieving an energy saving rate of over 60%. The air-source system indirectly cools through cooling water circulation, avoiding the problem of a sharp drop in heat dissipation efficiency of traditional air conditioning outdoor units in high-temperature environments, making it suitable for outdoor extreme temperature scenarios.
[0022] 2. This utility model discloses a low-energy monitoring station for environmental monitoring. The station's walls are embedded with cooling pipes arranged in a "bow" shape within the concrete, forming a large heat dissipation surface. This allows for rapid absorption and even distribution of heat, ensuring the station's temperature remains stable within the range of 25±2℃. Furthermore, the plate heat exchanger utilizes a graphene nano-coating and an orthogonal cross-flow channel design, further enhancing heat transfer efficiency.

[0030] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0031] The following describes in detail, with reference to the accompanying drawings, a low-energy monitoring station for environmental monitoring according to an embodiment of the present invention.
[0032] Example
[0033] For easier understanding, please refer to Figures 1 to 4 An embodiment of a low-energy monitoring station for environmental monitoring provided by this utility model includes:
[0034] An air source temperature control system 100 includes a compressor 101, a condenser 102 and a cooling water pipeline 103. The compressor 101 generates cooling capacity through a refrigerant phase change cycle.
[0035] The station building wall is embedded with cooling pipes 200, which are embedded in the wall structure of the monitoring station building 300 to form a closed loop.
[0036] The plate heat exchanger 400 is provided with a first heat exchange channel 401 and a second heat exchange channel 402. The first heat exchange channel 401 is connected to the cooling water pipe 103 of the air source temperature control system 100 to form a first circulation loop, and the second heat exchange channel 402 is connected to the embedded cooling pipe 200 of the station building wall to form a second circulation loop.
[0037] The first and second circulation loops achieve cross-type heat exchange through a plate heat exchanger 400. The air-source heat pump temperature control system 100 further includes:
[0038] Evaporator 104 is located at the outlet end of compressor 101;
[0039] An expansion valve 105 is connected between the condenser 102 and the evaporator 104. The cooling water pipe 103 passes through the interior of the evaporator 104, and the refrigerant flow channel and the cooling water flow channel form a heat exchange structure. The COP value of the air source temperature control system 100 is 3.2-4.1.
[0040] It should be noted that the air source heat pump temperature control system 100 consists of a compressor 101, a condenser 102, an evaporator 104, an expansion valve 105, and a cooling water pipe 103. The outlet end of the compressor 101 is connected to the evaporator 104. The refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 101 and then enters the evaporator 104 to release its cooling capacity. The condenser 102 is connected to the evaporator 104 via the expansion valve 105. After liquefaction in the condenser 102, the refrigerant is throttled and depressurized by the expansion valve 105 to form a low-temperature gas-liquid mixture, which returns to the evaporator 104 to complete the phase change cycle. The cooling water pipe 103 runs through the interior of the evaporator 104, forming a counter-current heat exchange structure with the refrigerant flow channel. After being cooled to 5-10°C by the refrigerant in the evaporator 104, the cooling water enters the first heat exchange channel 401 of the plate heat exchanger 400 via the cooling water pipe 103, forming the first circulation loop. The system's energy efficiency ratio (COP) is 3.2-4.1, which is significantly higher than that of traditional air conditioners.
[0041] The second circulation loop exchanges heat with the first circulation loop through the second heat exchange channel 402 of the plate heat exchanger 400.
[0042] The plate heat exchanger 400 is made of stacked 316L stainless steel plates, with the first heat exchange channel 401 and the second heat exchange channel 402 arranged orthogonally. After the cooling water completes heat transfer in the plate heat exchanger 400, the water temperature in the first circulation loop rises to 12-15℃ and returns to the air source temperature control system 100 for recooling; the water temperature in the second circulation loop drops to 18-22℃ and enters the embedded cooling pipes 200 in the station building wall to dissipate heat evenly into the station building.
[0043] In some embodiments, the station building wall-embedded cooling pipes 200 are arranged in a reciprocating "bow" shape on the wall.
[0044] It should be noted that the embedded cooling pipes 200 in the station building wall are preferably made of HDPE pipes, which are embedded in the concrete wall of the monitoring station 300 in a reciprocating "bow" shape layout. The pipe diameter is preferably 20mm and the pipe spacing is preferably 150mm, forming a closed second circulation loop.
[0045] In some embodiments, the plate heat exchanger 400 is coated with a graphene nano-coating, and the graphene nano-coating is applied to the plate contact surface of the plate heat exchanger 400.
[0046] It should be noted that the plate contact surfaces of the plate heat exchanger 400 are coated with a graphene nano-coating with a thickness of 50-100 nm to enhance the thermal conductivity.
[0047] In some embodiments, an electronic water pump is installed at the water inlet of the embedded cooling pipe 200 in the station building wall, and the electronic water pump is located on the second circulation loop. A temperature sensor and a flow regulating valve are also installed at the nodes of the second circulation loop, and the flow regulating valve 603 and the temperature sensor 602 are connected to form a closed-loop control system.
[0048] It should be noted that the inlet of the embedded cooling pipe 200 in the station building wall is equipped with an electronic water pump 500 (such as a DC12V micro water pump), which drives the cooling water to circulate at a flow rate of 0.5-1.2 m / s. Temperature sensors 602 are installed at the inlet and outlet of the second circulation loop to monitor the water temperature in real time and compare it with a preset threshold, which is 25℃. When the detected outlet water temperature is higher than the threshold, the connected PLC controller adjusts the flow regulating valve 603 to increase the opening and increase the cooling water flow; conversely, it decreases the opening to save energy. The electronic water pump 500, temperature sensor 602, and flow regulating valve 603 constitute a closed-loop control system to ensure that the station building temperature is stable within the range of 25±2℃.
[0049] Working principle: After compressor 101 starts, the refrigerant absorbs heat from the water in cooling water pipe 103 within evaporator 104, cooling it down. The low-temperature cooling water enters plate heat exchanger 400 via first heat exchange channel 401, exchanging heat with the station building cooling water in second heat exchange channel 402. Driven by an electronic water pump, the station building cooling water flows through embedded cooling pipes 200 in the station building walls, absorbing heat from inside the station building before returning to plate heat exchanger 400 to release heat, forming a continuous heat dissipation cycle. This ensures the normal operation of equipment 5 inside monitoring station building 300. Temperature sensors provide real-time data feedback, dynamically adjusting the flow control valve to optimize system energy efficiency.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
