[0041] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings form a part of the present application and are used to explain the principles of the embodiments of the present application, but are not used to limit the scope of the present application.

[0042] The state of the temperature control cycle system is divided into four working conditions: automatic stop working condition, automatic heating working condition, automatic refrigeration working condition, and automatic ventilation working condition. The four working conditions influence and restrict each other.

[0043] Example 1

[0044] One specific embodiment of the present application mainly aims at feedback regulation of the temperature in the automatic stop working condition. The feedback mechanism is a manifestation of the systematization and institutionalization of the relationship in the feedback system, and is an automatic regulation phenomenon, which enables the system to maintain a stable state. Through the feedback mechanism, the functions and dynamic mechanisms of various complex systems can be deeply understood, and the common relationship between different forms of matter motion is further revealed.

[0045] The present application discloses an automatic control temperature control cycle method based on a feedback mechanism, as shown in Figure 1 The wind flows to control the temperature, enters the cabin from the inlet, exits from the outlet and returns to the temperature control equipment, and the wind from the temperature control equipment enters the cabin from the inlet, forming a closed loop.

[0046] Specifically, the method comprises the following steps:

[0047] Step S1: determining target temperature: a℃, b℃ or c℃;

[0048] Step S2: determining different temperature control strategies according to different target temperatures;

[0049] Step S3: controlling system automatically adjusting temperature according to control strategies under different target temperatures, and inlet temperature, return air temperature and outlet temperature of temperature control equipment, and air humidity of the environment where the temperature control equipment is located.

[0050] Step S4: real-time monitoring inlet temperature, return air temperature, outlet temperature of the temperature control equipment and humidity information of the environment where the temperature control equipment is located by sensors, and sending to the control system.

[0051] In one specific embodiment of the application, the specific value of the target temperature is set according to the needs.

[0052] In one specific embodiment of the application, a, b and c are an arithmetic sequence.

[0053] Alternatively, a=k1xd, b=k2xd+10, c=k3xd+15, wherein d is a natural number between 10 and 25, k1, k2 and k3 are fixed values between 0.6 and 1.5 (set according to seasonal characteristics and temperature and humidity characteristics), and a, b and c are an arithmetic sequence, and k1, k2 and k3 can accurately adjust the temperature difference of a, b and c, and can be suitable for temperature control adjustment under different geographical conditions and different climate conditions, and have better adaptability and are closer to actual needs.

[0054] For example, set d=20, k1=1.2, k2=0.8 and k3=0.6, then a=20x1.2=24, b=0.8x20+10=26 and c=0.6x20+15=27; that is, the target temperature in winter is 24℃, the target temperature in spring and autumn is 26℃, and the target temperature in summer is 27℃.

[0055] For example, set d=15, k1=1.4, k2=1 and k3=0.8, then a=15x1.4=21, b=1x15+10=25 and c=0.8x15+15=27; that is, the target temperature in winter is 21℃, the target temperature in spring and autumn is 25℃, and the target temperature in summer is 27℃.

[0056] In actual application, the specific values of a, b and c can be determined by setting the specific values of d, k1, k2 and k3, and the target temperature can be set according to the region, climate and production needs of actual application, so that the automatic control and temperature adjustment method of the application can be more suitable for actual needs.

[0057] In one embodiment of the present application, different target temperatures are set according to different seasons.

[0058] For example, b°C=a°C+10°C and c°C=a°C+20°C; the target temperature in summer is c°C, the target temperature in spring and autumn is b°C, and the target temperature in winter is a°C.

[0059] The target temperature can be a value or a range.

[0060] For example, when the target temperature is a value, a=10, b=20, and c=30; the target temperature in summer is 30°C; the target temperature in spring and autumn is 20°C, and the target temperature in winter is 30°C.

[0061] Alternatively, a=15, b=20, and c=25; the target temperature in summer is 25°C; the target temperature in spring and autumn is 20°C, and the target temperature in winter is 15°C.

[0062] Alternatively, when the target temperature is a range, for example, the target temperature in winter is <15°C, the target temperature in spring and autumn is 15°C≤target temperature≤25°C, and the target temperature in summer is 25°C<target temperature<30°C.

[0063] In step S1, the season is determined according to the specific date of each year (for example, X month X day, X is a natural number), and then the target temperature of the corresponding season is determined.

[0064] For example, it is set that April to June is spring, July to September is summer, October to November is autumn, and December, January to March is winter; when in winter, the target temperature is a°C; when in spring and autumn, the target temperature is b°C; and when in summer, the target temperature is c°C. That is, the season is determined according to the time node in a year, and then different target temperatures are set according to different seasons.

[0065] Preferably, the season judgment of the specific time node is artificially set according to the north-south hemisphere position and the specific latitude and longitude position of the temperature adjusting device.

[0066] Further, the demand of the user is to meet the standard of temperature and humidity at the same time, so the humidity must also be monitored. The humidity refers to the humidity in the cabin, as shown in Figure 1

[0067] Further, in step S2,

[0068] When the target temperature is a°C, step S21 is performed; the automatic temperature adjusting flowchart when the target temperature is a°C is shown in Figure 2

[0069] ​​When the target temperature is b℃, step S22 is executed; the automatic temperature adjustment flow chart when the target temperature is set to b℃ is shown in Figure 3 .

[0070] When the target temperature is c℃, step S23 is executed; the automatic temperature adjustment flow chart when the target temperature is set to c℃ is shown in Figure 4 .

[0071] (1) In the step S21:

[0072] It is judged whether the humidity (the humidity in the cabin) is greater than m%; when the humidity is greater than m%, step S211 is performed; when the humidity is less than or equal to m%, step S212 is performed.

[0073] Step S211: compare the return air temperature with b℃, and judge whether the return air temperature is less than b℃; if yes, enter the automatic heating working condition, otherwise enter the automatic refrigeration working condition.

[0074] That is, when the return air temperature is less than b℃, the temperature adjusting equipment enters the automatic heating working condition; when the return air temperature is greater than b℃, the temperature adjusting equipment enters the automatic refrigeration working condition.

[0075] Step S212: judge whether the temperature difference between the inlet temperature and the outlet temperature is greater than n℃, if yes, enter the automatic ventilation working condition; if not, enter step S213;

[0076] That is: when the temperature difference between the inlet temperature and the outlet temperature is greater than n℃, the temperature adjusting equipment enters the automatic ventilation working condition; when the temperature difference between the inlet temperature and the outlet temperature is less than or equal to n℃, the temperature adjusting equipment enters step S213.

[0077] Step S213: judge whether the outlet temperature is less than (a-1)℃ and the return air temperature is less than (a+5)℃, if yes, enter the automatic heating working condition, if not, keep the automatic stop working condition.

[0078] (2) In the step S22:

[0079] It is judged whether the humidity (the humidity in the cabin) is greater than m%; if yes, enter step S221, otherwise enter step S222.

[0080] That is, when the humidity is greater than m%, step S221 is performed; when the humidity is less than or equal to m%, step S222 is performed;

[0081] Step S221: when the humidity is greater than m%, judge whether the return air temperature is less than b℃;

[0082] If yes, enter the automatic heating working condition,

[0083] Otherwise, enter the automatic refrigeration working condition;

[0084] Step S222: When the humidity is less than or equal to m%, determine whether the temperature difference between the inlet temperature and the outlet temperature is greater than n℃;

[0085] If yes, enter the automatic ventilation working condition;

[0086] If no, enter step S223.

[0087] Step S223: Determine whether the outlet temperature is less than (b-10)℃ and the return air temperature is less than (b-5)℃; if yes, enter the automatic heating working condition; otherwise, execute step S224;

[0088] Step S224: Determine whether the outlet temperature is greater than (b+10)℃ and the return air temperature is greater than b℃;

[0089] If yes, enter the automatic refrigeration working condition;

[0090] If no, keep the automatic stop working condition.

[0091] (3) In the step S23:

[0092] Determine whether the humidity (the humidity in the cabin) is greater than m%; if yes, enter step S231, otherwise enter step S232.

[0093] Step S231: When the humidity is greater than m%, determine whether the return air temperature is less than b℃; if yes, enter the automatic heating working condition; otherwise, enter the automatic refrigeration working condition;

[0094] Step S232: When the humidity is less than or equal to m%, determine whether the temperature difference between the inlet temperature and the outlet temperature is greater than n℃; if yes, enter the automatic ventilation working condition; otherwise, enter step S233.

[0095] Step S233: Determine whether the outlet temperature is greater than (c+1)℃ and the return air temperature is greater than b℃; if yes, enter the automatic heating working condition; otherwise, keep the automatic stop working condition.

[0096] In implementation:

[0097] Due to the influence of the external environment, the present application sets three target temperature conditions, a℃, b℃ and c℃, for example, and the relationship between the three is b=a+10℃, c=a+20℃. The division of the three temperature conditions is more suitable for the change of different seasons, so that the feedback temperature of the temperature regulating system is different in different seasons.

[0098] The temperature control device adjusts different working conditions of the device according to seasonal changes and real-time monitoring of inlet temperature, return air temperature, outlet temperature and humidity information of the environment where the temperature control device is located through sensors, and realizes real-time automatic switching of automatic shutdown working condition, automatic heating working condition, automatic refrigeration working condition and automatic ventilation working condition.

[0099] Embodiment 2

[0100] In one specific embodiment of the present application, the temperature of the cabin in the device is regulated based on the automatic control temperature regulation cycle method based on the feedback mechanism in Embodiment 1,

[0101] 1) According to different time nodes, the season is set as:

[0102] April to June is spring, July to September is summer, October to November is autumn, and December, January to March is winter.

[0103] 2) For different seasons, the given target temperature index requirement is:

[0104] In summer, the environment needs to be cooled, and the target temperature is c℃; in spring and autumn, the target temperature is b℃; in winter, the environment needs to be heated, and the target temperature is a℃.

[0105] Specifically: taking a=10℃, b=20℃, c=30℃ as an example to illustrate the operation process of the automatic control temperature regulation cycle method of the present application.

[0106] When in summer, the target temperature is 30℃; when in spring and autumn, the target temperature is 20℃; when in winter, the target temperature is 10℃.

[0107] 3) Further, the humidity index is 48%, the return air temperature index b℃ is 20℃, and the return air temperature index n℃ is 8℃.

[0108] Winter is cold and dry, and summer is hot and humid; the automatic control temperature cycle method of the present application can calibrate the determination of the season according to the judgment of the high and low humidity.

[0109] That is, after determining the season by time, the control strategy to be executed is further determined by judging the humidity, so as to realize accurate judgment of the environment and ensure the accuracy of temperature regulation.

[0110] 4) When the target temperature is 10℃:

[0111] As shown in Figure 2 , it is judged whether the humidity (cabin humidity) is greater than 48%;

[0112] When the humidity is greater than 48%, compare the return air temperature with 20℃, to determine whether the return air temperature is less than 20℃; if yes, enter the automatic heating working condition, otherwise enter the automatic refrigeration working condition. That is, when the return air temperature is less than or equal to 20℃, it is determined that the ambient temperature is low, and the temperature adjusting device enters the automatic heating working condition; when the return air temperature is greater than 20℃, it is determined that the ambient temperature is high, and the temperature adjusting device enters the automatic refrigeration working condition.

[0113] When the humidity is greater than 48%, the main temperature control requirement at this time is to adjust the temperature, and the ambient temperature is determined according to the return air temperature. By comparing the size of the return air temperature, the running condition of the temperature control device is determined, when greater than 20℃, refrigeration is performed to reduce the ambient temperature, when the return air temperature is less than or equal to 20℃, heating is performed to increase the ambient temperature, and finally the ambient temperature is kept stable at about 20℃.

[0114] When the humidity is less than or equal to 48%, it is determined whether the temperature difference between the inlet temperature and the outlet temperature is greater than 8℃, when the temperature difference between the inlet temperature and the outlet temperature is greater than 8℃, the temperature difference is greater than 8, which represents that the temperature difference before and after is large, and ventilation is needed to balance the temperature difference before and after, and the temperature adjusting device enters the automatic ventilation working condition; when the temperature difference between the inlet temperature and the outlet temperature is less than or equal to 8℃, it is within the temperature difference range, and the next condition is judged.

[0115] Next, it is determined whether the outlet temperature is less than 9℃ and the return air temperature is less than 15℃, if yes, the return air temperature (ambient temperature) is too low, and the automatic heating working condition is entered; if not, it means that the ambient temperature is too high, and the automatic stop working condition is entered.

[0116] When the humidity is less than or equal to 48%, it is determined that the season is in a relatively low temperature and not hot environment, at this time the main temperature control requirement is to improve the temperature comfort, therefore, according to the return air temperature, the ambient temperature is determined, when the ambient temperature is less than 15℃, the heating working condition is entered, when the ambient temperature is greater than 15℃, the stop working condition is entered.

[0117] 5) When the target temperature is 20℃:

[0118] As shown in Figure 3 , it is determined whether the humidity (humidity in the cabin) is greater than 48%;

[0119] Further, when the humidity is greater than 48%, it is determined whether the return air temperature is less than 20℃; if yes, enter the automatic heating working condition, otherwise enter the automatic refrigeration working condition; when the humidity is greater than 48%, the temperature can be controlled to be stable at about 20℃.

[0120] When the humidity is less than or equal to 48%, it is determined whether the temperature difference between the inlet temperature and the outlet temperature is greater than 8°C; if yes, it enters the automatic ventilation working condition; if no, it is determined whether the outlet temperature is less than 10°C and the return air temperature is less than 15°C; if yes, it enters the automatic heating working condition; if no, it is determined whether the outlet temperature is greater than 30°C and the return air temperature is greater than 20°C; if yes, it enters the automatic refrigeration working condition; if no, it remains in the automatic stop working condition.

[0121] When the humidity is less than 48°C, the ambient temperature is determined according to the return air temperature; when the return air temperature is less than 10°C, it enters the heating working condition to increase the ambient temperature. When the return air temperature is greater than 20°C, it enters the refrigeration working condition to decrease the ambient temperature.

[0122] 6) When the target temperature is 30°C:

[0123] As shown in Figure 4 , it is determined whether the humidity (cabin humidity) is greater than 48%;

[0124] When the humidity is greater than 48%, it is determined whether the return air temperature is less than 20°C; if yes, it enters the automatic heating working condition; otherwise, it enters the automatic refrigeration working condition.

[0125] When the humidity is greater than 48%, the main temperature control requirement at this time is to adjust the temperature, and the ambient temperature is determined according to the return air temperature. By comparing the size of the return air temperature, the running condition of the temperature control device is determined; when it is greater than 20°C, refrigeration is performed to decrease the ambient temperature; when the return air temperature is less than or equal to 20°C, heating is performed to increase the ambient temperature, and finally the ambient temperature is kept stable at about 20°C.

[0126] When the humidity is less than or equal to 48%, it is determined whether the temperature difference between the inlet temperature and the outlet temperature is greater than 8°C;

[0127] Further, if the temperature difference between the inlet temperature and the outlet temperature is greater than 8°C, it enters the automatic ventilation working condition; if the temperature difference is greater than 8, it means that the temperature difference before and after is large, and ventilation is needed to balance the temperature difference before and after. The temperature difference should not be too large.

[0128] If the temperature difference between the inlet temperature and the outlet temperature is less than 8°C, it is determined whether the return air temperature is greater than 20°C; if the return air temperature is greater than 20°C, it enters the automatic heating working condition; otherwise, the return air temperature is less than or equal to 20°C, and it remains in the automatic stop working condition.

[0129] When the humidity is less than 48°C, the ambient temperature is determined according to the return air temperature; when the return air temperature is less than 20°C, it ventilates to increase the ambient comfort; when the return air temperature is greater than 20°C, it enters the refrigeration working condition to decrease the ambient temperature.

[0130] Compared with the prior art, the application is based on the temperature information collected by the sensor, and the temperature information is fed back to automatically control the temperature regulation cycle, mainly aiming at the feedback regulation of the temperature under the automatic shutdown working condition of the temperature regulation system, and an automatic control temperature regulation cycle method based on a feedback mechanism is provided, so that the time cost and resource waste of manpower and financial resources of temperature regulation control are solved.

[0131] The automatic control temperature regulation cycle method of the application not only realizes the index requirement of the temperature, but also guarantees the use safety of the equipment, saves the human resource cost, and greatly improves the reliability and safety of the equipment.

[0132] The automatic control temperature regulation cycle method of the application determines the season through time, calibrates the season judgment through the monitoring of humidity, judges the size of the environment temperature through the monitoring of the return air temperature, determines the switching between different working conditions of the temperature control system, and realizes the self-feedback temperature control through the feedback of the return air temperature, the inlet temperature and the outlet temperature.

[0133] The above is only the preferred specific implementation of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application.
