The waste generated by the experiments cannot be properly treated and is directly discharged into the atmosphere, which will more or less cause adverse effects on the atmospheric environment; the other is small-scale indoor experiments. Ordinary laboratories cannot meet the temperature, pressure or humidity conditions required for various meteorological experiments. For example, it is difficult to simulate the low temperature and negative pressure environment at an altitude of 10,000 meters, and it is not repeatable. Since scientific experiments often require precise control of experimental conditions and repeated attempts to find better ways to affect the environment, a large laboratory body has been established to simulate various weather environments by controlling the pressure, temperature and humidity of its closed inner cavity; on this basis, how to provide a temperature control system to stably control the temperature inside the laboratory body and provide conditions for meteorological experiments has become a technical problem that technicians in this field currently need to solve.

[0022] The temperature control system for an artificial weather modification laboratory system provided by the present invention comprises a refrigeration unit, a heating unit, an automatic control system, and an external connection interface. Through information interaction between the automatic control system and the laboratory body, the series and parallel operations of the refrigeration unit, the heating unit, and the external connection interface are adjusted to adjust the temperature of the liquid flowing into the laboratory interlayer and other required subsystems to the required temperature, and ultimately the temperature of the gas in the laboratory body is controlled to reach the required value.

[0023] The refrigeration unit adopts multi-stage compression refrigeration to reduce the temperature of the liquid flowing into the laboratory interlayer and other required subsystems to the required temperature. The liquid reduces the gas in the laboratory to the required temperature through heat conduction through the tank wall or direct heat exchange with the gas-liquid heat exchanger. According to the design parameters of the laboratory body and the specific heat capacity of the gas and liquid required for the laboratory experiment, the power, cooling capacity and heat exchanger parameters of the refrigeration unit are calculated. Finally, according to the reasonably designed refrigeration unit, the temperature of the laboratory gas is adjusted with the help of the liquid with temperature information. Since the liquid has a higher specific heat capacity than the gas, it is more conducive to the temperature control accuracy of the gas in the laboratory.

[0024] The heating unit raises the temperature of the liquid flowing into the laboratory interlayer and other subsystems to the required temperature through controllable electric heating and steam heat exchange. The liquid raises the gas in the laboratory to the required temperature through heat conduction from the tank wall or direct heat exchange with the gas-liquid heat exchanger. According to the design parameters of the laboratory body and the specific heat capacity of the gas and liquid required for the laboratory experiment, the maximum heating capacity and the minimum controllable heating capacity of the heating unit are calculated. According to the reasonably designed heating unit, the temperature of the laboratory gas is adjusted with the help of the liquid with temperature information. Since the liquid has a higher specific heat capacity than the gas, it is more conducive to the temperature control accuracy of the gas in the laboratory.

[0025] The automatic control system can adjust the operating status of the refrigeration unit and the heating unit according to the set needs, adjust the temperature of the liquid flowing into the laboratory interlayer and other required subsystems to the required temperature, and the liquid raises the gas in the laboratory to the required temperature through the heat conduction of the tank wall or the direct heat exchange with the gas-liquid heat exchanger. The automatic control system collects the liquid temperature information in the pipeline and the gas temperature information in the laboratory body in real time, adjusts the opening of the valve group, the power of the compressor, the power of the heater and the amount of steam to accurately control the liquid temperature, and finally stabilizes the temperature of the gas in the laboratory body. At the same time, with the help of the information interaction of the control system of the laboratory body, the data is exchanged with the pressure control system and the humidity control system in the laboratory, and the influence of pressure and humidity changes on the temperature control system is continuously learned. When the gas pressure and humidity change, the temperature of the gas in the laboratory body is stabilized, or changed to the temperature selected by the experiment.

[0026] The external connection interface is connected to the laboratory body and other subsystems in a switchable manner between series and parallel. The series and parallel modes between different interfaces are switched according to experimental needs, and the flow direction of the liquid containing temperature control information is changed to change the temperature distribution in the laboratory body. The series mode can use the temperature difference between the liquid inlet and outlet to produce a gradient temperature control effect in the laboratory, and the parallel connection mode can ensure uniform heat distribution in various parts of the laboratory, resulting in a uniform temperature control effect.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Please refer to Figure 1 , Figure 1 This is a structural block diagram of a specific embodiment of the temperature control system of the artificial weather modification laboratory system provided by the present invention.

[0029] In this embodiment, the temperature control system 100 is used in an artificial weather modification laboratory system. The artificial weather modification laboratory system includes a laboratory body, which has a closed inner cavity. The closed inner cavity is a space for simulating various weather phenomena. Specifically, various weather phenomena are simulated by controlling the temperature, pressure and humidity of the inner cavity of the body to conduct meteorological experiments, thereby providing an experimental basis for artificial weather modification.

[0030] The temperature control system provided in this embodiment is used to control the gas temperature in the inner cavity of the main body according to the experimental requirements, so as to make the experiment repeatable and provide accurate experimental data for artificial weather modification.

[0031] In this embodiment, the temperature control system 100 includes a refrigeration unit 110, a heating unit 120, an automatic control system 130 and an external connection interface; wherein the refrigeration unit 110 is used to reduce the gas temperature in the main body of the laboratory system to a set temperature; the heating unit 120 is used to increase the gas temperature in the main body of the laboratory system to a set temperature. The set temperature here is determined according to the experimental requirements.

[0032] In a specific solution, the refrigeration unit 110 can use multi-stage compression refrigeration to reduce the temperature of the liquid flowing into the main body interlayer 200 of the laboratory system, thereby controlling the temperature of the gas in the main body.

[0033] In a specific solution, the heating unit 120 can be used to increase the temperature of the liquid flowing into the main body interlayer 200 of the laboratory system by means of electric heating and steam heat exchange, thereby controlling the temperature of the gas in the main body.

[0034] Specifically, the liquid may be a coolant, and of course may also be other liquid refrigerants containing temperature control information.

[0035] The main body of the experimental system has a closed inner cavity with a main body interlayer 200 on the outer periphery. The temperature of the main body inner cavity can be controlled by the temperature of the liquid flowing in the main body interlayer 200, that is, the gas temperature of the main body inner cavity can be controlled by heat conduction through the tank wall.

[0036] Of course, in addition to the heat conduction method of the tank wall, the gas temperature in the main body can also be controlled by a gas-liquid heat exchanger. Obviously, the liquid temperature in the gas-liquid heat exchanger is controlled by the refrigeration unit 110 or the heating unit 120. The gas in the gas-liquid heat exchanger is transported to the inner cavity of the main body after heat exchange with the liquid, thereby changing the gas temperature in the inner cavity of the main body.

[0037] The automatic control system 130 is used to adjust the operating status of the refrigeration unit 110 and the heating unit 120 to adjust the temperature of the liquid flowing into the main body interlayer 200 of the laboratory system to a set temperature.

[0038] Obviously, the automatic control system 130 is in communication connection with the refrigeration unit 110 and the heating unit 120, and can control the operation of the refrigeration unit 110 and the heating unit 120 according to the required temperature of the gas in the main body cavity.

[0039] In a specific scheme, the automatic control system 130 can collect the temperature information of the liquid in the pipeline between the temperature control system 100 and the main body interlayer 200, as well as the temperature information of the gas in the main body, and adjust the parameters of the refrigeration unit 110 or the heating unit 120 according to the collected temperature information to stabilize the gas temperature in the main body.

[0040] Specifically, the power, cooling capacity and heat exchanger parameters of the refrigeration unit 110 can be designed and calculated based on the design parameters of the main body of the laboratory system and the specific heat capacity of the gas and liquid required for the laboratory system to conduct experiments, so as to reasonably design the refrigeration unit 110.

[0041] Specifically, design parameters such as the maximum heating capacity and the minimum controllable heating capacity of the heating unit 120 can also be designed and calculated based on the design parameters of the main body of the laboratory system, the specific heat capacity of the gas and liquid required for the laboratory system to conduct experiments, etc., so as to reasonably design the heating unit 120.

[0042] When the automatic control system 130 adjusts the refrigeration unit 110 or the heating unit 120, it can control the liquid temperature by adjusting the opening of the valve group in the connecting pipeline, the power of the compressor involved, the power of the heater and the amount of steam, so as to ultimately stabilize the gas temperature in the main body.

[0043] In a specific scheme, the automatic control system 130 of the temperature control system 100 is communicatively connected with the main control system of the main body. The main control system can collect data information of the pressure control system 400 and the humidity control system of the laboratory system. The automatic control system 130 can adjust the refrigeration unit 110 or the heating unit 120 according to the data information collected by the main control system to stabilize the gas temperature in the main body or adjust the gas temperature in the main body to the set temperature.

[0044] It can be understood that changes in the pressure and humidity parameters of the main cavity of the laboratory system will affect the temperature changes. After the automatic control system 130 communicates with the main control system, it can understand the interaction of the various parameters in the main cavity, which is convenient for experimenters to know the interaction between the various parameters. At the same time, it is also convenient to determine different experimental conditions. When the gas pressure and humidity in the main cavity change, the temperature control system 100 can control the temperature of the main cavity accordingly. The control includes stabilizing the temperature at a set value or adjusting the temperature to a desired set value.

[0045] In addition to the temperature control system 100, the weather modification laboratory system also includes other subsystems, such as a pressure control system 400 for adjusting the pressure in the main body cavity, and a cryogenic drying system 300 for controlling the temperature and humidity in the main body cavity.

[0046] In a specific scheme, the cryogenic drying system 300 may include a multi-stage heat exchange device and a high-efficiency air supply device, which can rapidly cool the air and then send it into the inner cavity of the main body; it can be understood that for the multi-stage heat exchange device of the cryogenic drying system 300, a liquid capable of heat exchange is also required, so in actual applications, the external connection interface of the temperature control system 100 also includes an interface connected to the cryogenic drying system 300, so as to send the liquid into the cryogenic drying system 300 for heat exchange, wherein the temperature of the liquid sent into the cryogenic drying system 300 can be controlled according to actual needs.

[0047] In the specific solution, the pressure control system 400 includes structures such as a dryer and a heat exchanger unit, and also requires a liquid that can perform heat exchange. Therefore, in actual applications, the external connection interface of the temperature control system 100 may also include an interface connected to the pressure control system 400 to allow liquid to be sent into the pressure control system 400 for heat exchange. Similarly, the temperature of the liquid sent into the pressure control system 400 can be controlled according to actual needs.

[0048] As described above, it can be understood that for other subsystems of the artificial weather modification laboratory system connected to the temperature control system 100, the refrigeration unit 110 is also used to reduce the liquid temperature of the subsystem flowing into the laboratory system to a set temperature through multi-stage compression refrigeration, and the heating unit 120 is also used to increase the liquid temperature of the subsystem flowing into the laboratory system to a set temperature through electric heating and steam heat exchange.

[0049] The subsystems here include the pressure control system 400 and the cryogenic drying system 300 mentioned above; of course, for other necessary subsystems of the laboratory system, the temperature control system 100 can also be connected to other necessary subsystems through its external connection interface.

[0050] like Figure 1 As shown, the temperature control system 100 is connected to the corresponding interfaces of the main body interlayer 200, the cryogenic drying system 300 and the pressure control system 400 through pipelines through its external connection interface, so that the liquid forms a flow loop between the corresponding pipelines; in actual applications, the external connection interface of the temperature control system 100 and the subsystems of the main body interlayer 200 and the laboratory system can be connected in series or in parallel to meet different experimental requirements.

[0051] Specifically, a first liquid flow circuit is provided between the temperature control system 100 and the main interlayer 200 via an external connection interface, a second liquid flow circuit is provided between the temperature control system 100 and the deep cold drying system 300 via an external connection interface, and a third liquid flow circuit is provided between the temperature control system 100 and the pressure control system 400 via an external connection interface; valve components are provided on the above-mentioned first, second and third liquid flow circuits. In actual applications, the switching state of each valve component is controlled by the automatic control system 120, so that the first, second and third liquid flow circuits can be connected in series or in parallel.

[0052] It can be understood that the temperature control system 100 can be provided with multiple external connection interfaces as needed, or multiple branches can be divided as needed.

[0053] Specifically, corresponding valves can be arranged on the connecting pipelines, and the series connection or parallel connection between the flow circuits can be realized by switching the valves.

[0054] In addition, the temperature control system 100 can also change the flow direction of the liquid containing temperature control information in the main body interlayer 200 through the series-parallel design of corresponding pipelines, thereby changing the temperature distribution of the main body inner cavity.

[0055] Specifically, the main body interlayer 200 is divided into more than two mutually unconnected sub-layers from top to bottom, and the external connection interface of the temperature control system 100 has interface parts corresponding to the number of sub-layers, and each interface part of the temperature control system 100 is connected with the corresponding sub-layer through a connecting pipeline, that is, the temperature control system 100 forms a flow circuit with each sub-layer, and the automatic control system 130 can control each flow circuit to be connected in series or in parallel; specifically, when each flow circuit is connected in series, a gradient temperature control effect can be generated in the main body, and when each flow circuit is connected in parallel, a uniform temperature control effect can be generated in the main body.

[0056] The temperature control system of the weather modification laboratory system provided by the present invention is introduced in detail above. Specific examples are used in this paper to illustrate the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
