Detailed Description of the Embodiments

[0017] The following further describes the present invention in detail with reference to the drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0018] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the existence or addition of one or more other elements or their combinations.

[0019] As Figure 1 shown, the present invention provides a cold and warm air circulation system of compression refrigeration and electromagnetic heating, including: an electromagnetic heating device 1 and a refrigeration device 2 arranged in parallel. The air outlet ends of both are connected to the heat exchange tube 6 in the target environmental space through a circulating gas storage tank 3, and the air inlet ends of both are connected to the recovery gas storage tank 4 and the heat exchange tube 6 in sequence through a circulating device 5.

[0020] Among them, the target environmental space includes, but is not limited to, the environmental space where people live, work and reside; The electromagnetic heating device 1 uses an electromagnetic heating body to heat the passing gas, the refrigeration device 2 uses a refrigeration compressor to refrigerate the passing gas, and the circulation device 5 uses a circulation device capable of transporting high-temperature and low-temperature gases and pressurizing the gases; The gas used in the system can be air. The air needs to be dried and then introduced into the recovery gas storage tank 4 of the system. When the dry air circulates in the system, the equipment, pipelines and valves in the circulation path will not rust or corrode, which can improve the service life of the entire system; During operation, the circulation device 5 provides power for gas circulation. The gas in the recovery gas storage tank 4 enters the electromagnetic heating device 1 for heating under the heating condition, and enters the refrigeration device 2 for cooling under the refrigeration condition. The gas that has been heated or refrigerated enters the heat exchange tube 6 in the target environmental space and exchanges heat with the target environmental space to achieve the purpose of heating or refrigeration; then, the gas in the heat exchange tube 6 will flow back to the recovery gas storage tank 4 after heat exchange, and thus circulates for refrigeration or heating.

[0021] The present invention sets the electromagnetic heating device 1 and the refrigeration device 2 in one system, replaces the traditional boiler heating method and the refrigeration and heating methods of air conditioners, realizes the combination of refrigeration and heating, and can be switched according to the needs of refrigeration and heating; moreover, the dry gas circulates in the system, which can prevent the equipment in the circulation path from rusting and corroding, and improves the service life of the entire system; the heat exchange tube 6 is used to exchange heat with the target environmental space, avoiding blowing air into the target environmental space, realizing the recycling of gas and making people more comfortable, and achieving energy conservation, environmental protection and hygiene.

[0022] As Figure 1 shown, further, a first valve 7 is connected between the electromagnetic heating device 1 and the circulation device 5, a second valve 8 is connected between the refrigeration device 2 and the circulation device 5, a third valve 9 is connected between the circulation gas storage tank 3 and the intake end of the heat exchange tube 6, and a fourth valve 10 is connected between the recovery gas storage tank 4 and the outlet end of the heat exchange tube 6.

[0023] Among them, the first valve 7, the second valve 8 and the third valve 9 adopt globe valves, and the fourth valve 10 adopts a check valve.

[0024] Under the heating condition, the first valve 7 is opened and the second valve 8 is closed. Under the refrigeration condition, the second valve 8 is opened and the first valve 7 is closed. The third valve 9 can adjust the gas flow rate discharged from the circulation gas storage tank 3; All valves in the system are controlled by the control module of the system to enable the stable circulation of gas in the system under different control strategies, and cooperate with the electromagnetic heating device 1 and the refrigeration device 2 to work, so as to improve the temperature control accuracy in the target environmental space.

[0025] Further, when the circulation device 5 works, the temperature of the gas passing through is 2°C - 300°C, and the gas pressure provided for the circulation gas storage tank 3 is 0.2 MPa - 3 MPa.

[0026] The temperature control of the gas in the system is within the range of 2°C - 300°C to prevent damage to the equipment in the system caused by too high or too low temperature. The circulation device 5 pressurizes the gas and transports it into the circulation gas storage tank 3. The gas pressure in the circulation gas storage tank 3 is controlled within the range of 0.2 MPa - 3 MPa. On the premise of ensuring the stable circulation of the gas in the system, prevent the gas pressure from exceeding the bearing capacity of the circulation gas storage tank 3.

[0027] Further, in the refrigeration condition, the temperature in the circulation gas storage tank 3 is 2°C - 20°C, and the pressure is 0.2 MPa - 3 MPa; in the heating condition, the temperature in the circulation gas storage tank 3 is 20°C - 200°C, and the pressure is 0.2 MPa - 3 MPa; according to actual needs, set and adjust the temperature and pressure of the gas within the above temperature range and pressure range.

[0028] In one embodiment, it further includes: a control module, which is used to switch the working states of the electromagnetic heating device 1 and the refrigeration device 2, and control the temperature and pressure of the gas in the circulation gas storage tank 3 under the refrigeration condition and the heating condition.

[0029] When refrigeration is required, the control module controls the first valve 7 to close, and the second valve 8 and the third valve 9 to open, and the refrigeration device 2 starts to work; when heating is required, the control module controls the second valve 8 to close, and the first valve 7 and the third valve 9 to open, and the electromagnetic heating device 1 starts to work; The gas flow rate entering the refrigeration device 2 is adjusted by adjusting the opening degree of the second valve 8, the gas flow rate entering the electromagnetic heating device 1 is adjusted by adjusting the opening degree of the first valve 7, and the gas flow rate discharged from the circulation gas storage tank 3 is adjusted by adjusting the opening degree of the third valve 9, so as to control the pressure of the gas in the circulation gas storage tank 3. The control module is used to control the refrigeration temperature of the refrigeration device 2 or the heating temperature of the electromagnetic heating device 1 to control the temperature of the gas in the circulation gas storage tank 3; by controlling the temperature and pressure of the gas in the circulation gas storage tank 3, the real-time temperature and real-time pressure of the gas can meet the set operation requirements.

[0030] As Figure 2 shown, in one embodiment, the control module includes: A load prediction unit predicts the load demand within a set future time based on the preprocessed real-time environmental status data and in combination with the time dimension. Among them, the load demand includes: the cooling load demand under the cooling condition and the heating load demand under the heating condition.

[0031] Among them, the real-time environmental status data includes: the temperature and humidity inside and outside the target environmental space, and the personnel density inside the target environmental space; the temperature and humidity can be obtained through temperature sensors and humidity sensors inside the target environmental space, and the personnel density inside the target environmental space can be detected by infrared detection or cameras. If the target environmental space is a space with large personnel mobility such as a shopping mall and an office building, it is necessary to obtain the personnel density. If the target environmental space is a living environment of people, it is not necessary to obtain the personnel density and can be ignored. The time dimension includes one or more of: season, time period, and weekday or holiday mode; for example, if the target environmental space is a space with large personnel mobility such as a shopping mall and an office building, the time dimension includes season, time period, and weekday or holiday mode. If the target environmental space is a living environment of people, the time dimension includes season and time period. Preprocessing the real-time environmental status data includes filtering and normalization processing (which is prior art and will not be elaborated further) to eliminate noise interference and obtain the preprocessed real-time environmental status data. To predict the load demand within a set future time, a trained LSTM (Long Short-Term Memory Network) neural network model or a Transformer time series model can be used for prediction. The preprocessed real-time environmental status data and time dimension data are input into the trained prediction model to predict the heating load demand or cooling load demand within a set future time. The set time can be from 1 hour to 24 hours. An optimization unit optimizes the system operation parameters using an optimization algorithm based on the predicted load demand to obtain the target system operation parameters. A control unit executes the target system operation parameters.

[0032] The following provides two optimization methods for the optimization unit: The first optimization method is to determine the initial system operation parameters based on the predicted load demand, and then use an optimization algorithm to optimize the initial system operation parameters; the initial system operation parameters include: the working parameters of the electromagnetic heating device 1 or the refrigeration device 2, the opening degree of each valve, and the pressure setting value of the circulating gas storage tank 3. Specifically, the optimization unit adopts a multi-objective optimization algorithm, aiming at maximizing the system energy efficiency ratio, and taking the set range of the gas pressure in the circulating gas storage tank 3, the temperature fluctuation range of the circulating pipeline, and the operating temperature range of the electromagnetic heating device 1 or the refrigeration device 2 as the constraint conditions, to optimize the operating parameters of the electromagnetic heating device 1 or the refrigeration device 2, the opening degree of each valve, and the pressure setting value of the circulating gas storage tank 3, so as to obtain the target system operating parameters.

[0033] Among them, the system energy efficiency ratio under the refrigeration condition is: the ratio of the refrigeration capacity to the sum of the power consumption of the refrigeration device 2 and the power consumption of the circulating device 5; the system energy efficiency ratio under the heating condition is: the ratio of the heating capacity to the sum of the power consumption of the electromagnetic heating device 1 and the power consumption of the circulating device 5; The set range of the gas pressure in the circulating gas storage tank 3: 0.2 MPa - 3 MPa; it can be adjusted according to the actual situation of the circulating gas storage tank 3, mainly to prevent the gas pressure from exceeding the safety threshold of the circulating gas storage tank 3, and at the same time ensure that the gas pressure in the circulating gas storage tank 3 can make the gas be transported to the heat exchange tube 6; The temperature fluctuation range of the circulating pipeline: ±1 °C, under the condition that the load requirements in the target environmental space are the same, to avoid frequent temperature adjustment; The operating temperature range of the electromagnetic heating device 1: 20 °C - 200 °C; the operating temperature range of the refrigeration device 2: 2 °C - 20 °C; The operating parameters of the electromagnetic heating device 1 or the refrigeration device 2 are used to adjust the temperature of heating or cooling the gas, the opening degree of each valve is used to adjust the gas pressure in the circulating gas storage tank 3, and the size of the pressure setting value of the circulating gas storage tank 3 is used to balance the influence of the gas temperature after pressurization when storing gas. For example, when the gas is pressurized and stored in the circulating gas storage tank 3, the temperature of the gas may drop, which has a positive impact on the refrigeration temperature under the refrigeration condition and a negative impact on the heating temperature under the heating condition. Therefore, setting a suitable pressure setting value for the circulating gas storage tank 3 can further reduce the energy consumption of the electromagnetic heating device 1 or the refrigeration device 2.

[0034] As Figure 3 shown, the second optimization method is that the optimization unit includes: A determination subunit, which determines the control strategy of the system according to the predicted load demand and establishes a set of system operating parameters corresponding to the control strategy; The set of system operating parameters includes all possible combinations of system operating parameters under the control strategy; it represents the range within which the system operating parameters can vary during the adjustment process. For example, under the control strategy corresponding to the predicted load demand, the duty cycle range of the electromagnetic heating device 1 is a~b (the duty cycle of the electromagnetic heating device 1 is adjusted to control the output power size, thereby adjusting the heating temperature), the opening range of the first valve 7 is c~d, the opening range of the third valve 9 is e~f, and the pressure set value range of the circulating gas storage tank 3 is g~h. Then, multiple values are taken corresponding to each range of operating parameters, and multiple combinations formed by the multiple values of multiple operating parameters are used to establish the set of system operating parameters; The optimization subunit uses an optimization algorithm to seek the optimal system operating parameters from the set of system operating parameters corresponding to the control strategy and obtains the target system operating parameters; Based on the established set of system operating parameters, the optimal system operating parameters can be found using an optimization algorithm, that is, a set of optimal system operating parameters formed by the values of multiple operating parameters; the optimization algorithm will continuously search and try different combinations of system operating parameters in the set of system operating parameters, and evaluate each combination of system operating parameters. Based on the evaluation results, the optimization algorithm will adjust or change the search strategy to gradually approach the optimal system operating parameters. Iterate the above process to find the optimal system operating parameters. If the iteration reaches the set maximum number of times, stop searching and use the currently found set of optimal operating parameter values as the optimal system operating parameters, that is, the target system operating parameters.

[0035] As Figure 4 shown, further, the control unit includes: The adjustment subunit adjusts the temperature and pressure of the gas in the circulating gas storage tank 3 according to the target system operating parameters and obtains the feedback temperature data and feedback pressure data of the gas in the circulating gas storage tank 3; After adjustment according to the target system operating parameters, it will be fed back to the temperature and pressure of the gas in the circulating gas storage tank 3. During the adjustment process, multiple real-time temperatures and multiple real-time pressures of the gas in the circulating gas storage tank 3 are obtained, that is, the feedback temperature data and feedback pressure data, and these data represent the effects when the target system operating parameters are executed; The analysis subunit performs an optimization analysis on the feedback temperature data and feedback pressure data of the gas in the circulating gas storage tank 3 when at least one of the feedback temperature data and feedback pressure data in the circulating gas storage tank 3 does not meet the set operating requirements, and obtains the change trend of the system operating parameters; If both the feedback temperature data and the feedback pressure data meet the set operating requirements, it indicates that no adjustment is required for the current target system operating parameters; The analysis subunit analyzes the feedback temperature data and feedback pressure data, and compares the actual operation effect of the system with the preset operation effect. For example, by comparing the difference between the feedback temperature data (or feedback pressure data) in the circulating gas storage tank 3 and the preset temperature data (feedback pressure data), the operation effect can be compared from aspects such as the fluctuation situation and energy consumption situation, and the main problems affecting the operation effect of the system can be found. Analyze the main problems to determine the system operation parameters that need to be adjusted and their change trends. For example, if the system operation parameter to be adjusted is the opening degree of a certain valve, it is necessary to determine whether to increase or decrease the opening degree of this valve; of course, when adjusting the opening degree of a certain valve, it is also necessary to consider whether it affects other system operation parameters; in short, when at least one of the feedback temperature data and feedback pressure data does not meet the set operation requirements, it is necessary to optimize and analyze the feedback temperature data and feedback pressure data in the circulating gas storage tank 3 to obtain the change trend of the system operation parameters, so as to further adjust the target system operation parameters; The adjustment subunit sets an operation parameter adjustment model according to the change trend of the system operation parameters, uses the operation parameter adjustment model to adjust and optimize the comparison of the target system operation parameters, and uses the obtained optimized system operation parameters to adjust the temperature and pressure of the gas in the circulating gas storage tank 3; The function of the operation parameter adjustment model is to generate a new parameter value corresponding to the operation parameter to be adjusted according to the known change trend, so as to recombine with the other operation parameters that do not need to be adjusted to find a more optimal set of operation parameter values, so as to make the operation effect of the system better, such as better energy efficiency ratio, smaller temperature fluctuation and stable gas pressure and other operation effects; use the operation parameter adjustment model to optimize and compare the new set of system operation parameters, and obtain the system operation effects corresponding to different operation parameter combinations (which can be detected in the simulation model), so as to obtain the operation parameter combination that makes the system operation effect optimal as the new system operation parameters, that is, the optimized system operation parameters, so as to use the optimized system operation parameters to adjust the temperature and pressure of the gas in the circulating gas storage tank 3.

[0036] Among them, the operation parameter adjustment model can adopt any relationship model in the prior art that can reflect the relationship between the original position of an operation parameter and the position after the adjustment and change of this operation parameter; The operation parameter adjustment model is: Among them, is a random value between 0 and 1, which is used to introduce randomness into the process of adjusting and changing the operation parameters, and can explore different change trends to find possible more optimal system operation parameters, and are respectively the original position of an operation parameter and the position after the adjustment and change, is the tangent trigonometric function, which is beneficial for the operating parameters to vary within a large range, and is beneficial for increasing the range of searching for the optimal system operating parameters. is a constant. is the mathematical expectation of the normal distribution of a certain operating parameter, representing the average value of the operating parameter during the adjustment and change process, and is used to control the change range of the operating parameter.

[0037] Through the above operating parameter adjustment model, more possibilities can be sought for the change process of the operating parameters, so as to find more optimal system operating parameters.

[0038] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the present invention, the present invention is not limited to the specific details and the illustrated examples here.
