Description

Technical Field

[0001] The present invention relates to the technical field of air handling equipment, and in particular to a method for adjusting environmental parameters of multiple rooms, a device for adjusting environmental parameters of multiple rooms, an air handling equipment and a computer-readable storage medium. Background Art

[0002] The fresh air system has the ability to adjust temperature and humidity, and can control the temperature and humidity of multiple rooms at the same time. Each room is equipped with an operator that interacts with the fresh air system, allowing users to independently control the status of the room. When the whole-house smart mode is selected, it is inevitable that cooling and heating settings will exist at the same time.

[0003] In the related art, the target temperature and current temperature that the fresh air system needs to control are usually based on the average value, boundary value or the last setting of each room. If the target temperature and the current temperature are based on the average value of each room, the control of individual rooms may be easily ignored. If the boundary value or the last setting is used as the control basis, excessive temperature control may occur, which is not conducive to energy saving. At the same time, when the control target is opposite to the target expected by the user, it will lead to extremely poor comfort. Summary of the invention

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following describes in detail the multi-room environmental parameter adjustment method, device, air handling equipment and medium according to the embodiments of the present invention with reference to the accompanying drawings.

[0035] In the embodiment of the present invention, the air treatment device may be a fresh air system. Taking the fresh air system as an example, the fresh air system has the ability to adjust the temperature and humidity. For example, refer to Figure 1 As shown, the fresh air system 100 controls the temperature and humidity of N rooms at the same time. The N rooms are respectively room R1, room R2, ..., room Rn, and each room is equipped with a human-machine interface operator, at least one temperature sensor and at least one humidity sensor. The temperature sensor is used to detect the actual temperature in the room, and the humidity sensor is used to detect the relative humidity in the room. According to the actual temperature and relative humidity in the room, the actual humidity in the room can be calculated. For example, room R1 is equipped with operator P1, temperature sensor T1 and humidity sensor D1, room R2 is equipped with operator P2, temperature sensor T2 and humidity sensor D2, and room Rn is equipped with operator Pn, temperature sensor Tn and humidity sensor Dn. The fresh air system 100 is also equipped with a temperature sensor T and a humidity sensor D, which are used to detect the return air temperature Tr and the return air relative humidity of the fresh air system, respectively, and the return air humidity Dr can be calculated according to the relationship between the return air temperature and the return air relative humidity.

[0036] When the fresh air system is working, the room environment can be controlled independently. When at least two rooms are turned on through the operator, the whole house will uniformly execute the last set mode, such as cooling mode, heating mode, dehumidification mode, humidification mode, fresh air ventilation mode or smart mode. When the smart mode is selected, the energy demand of each room may be different, or even opposite. For example, cooling and heating may exist at the same time. If the average target temperature of each room and the average current temperature are taken as the control basis, the control of individual rooms is easy to be ignored. If the boundary value or the last setting is used as the control basis, the temperature and humidity will be over-adjusted, which is not conducive to energy saving and will also lead to extremely poor comfort.

[0037] In order to solve the above problems, this application proposes a method for adjusting environmental parameters of multiple rooms. Figure 2 When the user selects the intelligent mode, the temperature sensor and humidity sensor of each room detect the actual temperature and relative humidity of the corresponding room respectively, and obtain the corresponding actual humidity through the relationship between the actual temperature and relative humidity of the corresponding room, and transmit the actual temperature and humidity data of each room to the fresh air system. The fresh air system collects the set temperature Tsn, set humidity Dsn, actual room temperature Tn and actual room humidity Dn of each room, and statistically analyzes the data of each room to obtain the final data involved in energy control, that is, the optimal values ​​of target temperature, target humidity, current temperature and current humidity.

[0038] Figure 3 FIG. 1 is a flow chart of a method for adjusting environmental parameters of multiple rooms according to a second embodiment of the present invention. Figure 3 , the multi-room environmental parameter adjustment method may include:

[0039] S210, obtaining the actual temperature and set temperature of each room.

[0040] For example, refer to Figure 1 , rooms R1, R2 to Rn are all equipped with a human-machine interface operator and at least one temperature sensor. For example, room Rn is equipped with operator Pn and temperature sensor Tn. In room Rn, the user can select the fresh air system to run in intelligent mode through operator Pn, directly set the set temperature of room Rn to Tsn, and obtain the actual temperature Tn of room Rn through temperature sensor Tn. It should be noted that the actual temperature and set temperature of rooms R1 to Rn-1 are obtained in the same way as room Rn, and no examples are given here.

[0041] S220, determining the number of rooms to be heated, the number of rooms to be cooled, and the number of rooms to be kept at a constant temperature according to the actual temperature and the set temperature of each room.

[0042] For example, when the set temperature of the current room is greater than the actual temperature, it is determined that the room needs to be heated, that is, the room is a heated room; when the set temperature of the current room is less than the actual temperature, it is determined that the room needs to be cooled, that is, the room is a cooled room; when the set temperature of the current room is equal to the actual temperature, it is determined that the room needs to be kept at a constant temperature, that is, the room is a constant temperature room. The fresh air system collects the actual temperature and set temperature of each room, and compares the actual temperature and set temperature of each room to determine the situation of each room, and finally determines the number of heated rooms, cooled rooms, and constant temperature rooms.

[0043] S230, determining the target temperature and the current temperature according to the number of heating rooms, the number of cooling rooms and the number of constant temperature rooms.

[0044] Specifically, after the fresh air system determines the number of heated rooms, cooled rooms, and constant temperature rooms, it determines the energy requirements of the fresh air system when working in intelligent mode by comparing the number of heated rooms, cooled rooms, and constant temperature rooms, thereby determining the target temperature and current temperature.

[0045] For example, when there are a large number of cooling rooms, or a large number of cooling rooms and a large number of constant temperature rooms, and a small number of heating rooms, it can be considered that most rooms need to be cooled, and the target temperature and current temperature can be determined by the cooling demand. When there are a large number of heating rooms, or a large number of heating rooms and a large number of constant temperature rooms, and a small number of cooling rooms, it can be considered that most rooms need to be heated, and the target temperature and current temperature can be determined by the heating demand. When there are a large number of constant temperature rooms, and a small number of cooling rooms and heating rooms, it can be considered that most rooms need to be kept at a constant temperature, and the target temperature and current temperature can be determined by the constant temperature demand. In addition, when the fresh air ventilation mode is turned on in the room, the temperature of each room does not directly participate in the energy demand control, and the target temperature and current temperature can be determined by the return air data.

[0046] S240, performing energy demand control on the air handling equipment according to the target temperature and the current temperature.

[0047] Specifically, when the intelligent mode is selected, by comparing the number of heated rooms, the number of cooled rooms and the number of constant temperature rooms, the energy demand of the air handling equipment (fresh air system) is determined, which can be cooling, heating, constant temperature or fresh air ventilation. The target temperature and current temperature are determined under different energy demands. At the same time, the fresh air system intelligently adjusts the indoor environment according to the target temperature and current temperature.

[0048] In this way, by conducting statistical analysis on the actual temperature and set temperature of each room, the target temperature and current temperature are obtained, the energy demand control of the air handling equipment is realized, and the indoor temperature is intelligently adjusted to make the indoor environment more comfortable. At the same time, the needs of each room can be balanced to improve the energy efficiency of the entire machine.

[0049] In some embodiments, the target temperature and the current temperature are determined based on the number of heated rooms, the number of cooled rooms, and the number of constant temperature rooms, including: when the number of heated rooms is greater than or equal to the number of constant temperature rooms, or the number of cooled rooms is greater than or equal to the number of constant temperature rooms, determining the temperature difference for each room, and determining the target temperature and the current temperature based on the temperature difference for each room.

[0050] Specifically, when the number of rooms that need to be heated is greater than or equal to the number of rooms that need to be heated, it means that the number of rooms that need to be heated is large. At this time, the temperature difference between the set temperature and the actual temperature of each room can be analyzed according to the heating demand, and then the target temperature and current temperature are determined according to the temperature difference of each room. For example, the target temperature and current temperature are determined according to the set temperature and actual temperature of the room corresponding to the largest temperature difference, or according to the set temperature and actual temperature of the room corresponding to the smallest temperature difference. Then, the air conditioning processing equipment is controlled according to the target temperature and current temperature to intelligently adjust the room temperature.

[0051] When the number of cooling rooms is greater than or equal to the number of constant temperature rooms, it means that the number of rooms that need cooling is large. At this time, the temperature difference between the set temperature and the actual temperature of each room can be analyzed according to the cooling demand, and then the target temperature and current temperature are determined according to the temperature difference of each room. For example, the target temperature and current temperature are determined according to the set temperature and actual temperature of the room corresponding to the largest temperature difference, or according to the set temperature and actual temperature of the room corresponding to the smallest temperature difference. Then the air conditioning processing equipment is controlled according to the target temperature and current temperature to intelligently adjust the room temperature.

[0052] In some embodiments, when the number of cooling rooms is greater than or equal to the number of constant temperature rooms, the target temperature and current temperature are determined based on the temperature difference of each room, including: if the number of cooling rooms is greater than the number of heating rooms, then when the temperature difference of each room is greater than the first temperature threshold, and the temperature difference of any room is greater than or equal to the second temperature threshold, the room with the largest temperature difference is determined, and the minimum set temperature is determined from the room with the largest temperature difference as the target temperature, and the actual temperature of the room corresponding to the minimum set temperature is used as the current temperature, wherein the second temperature threshold is greater than the first temperature threshold, and the first temperature threshold and the second temperature threshold can be calibrated according to actual conditions.

[0053] Specifically, when the number of cooling rooms is greater than or equal to the number of constant temperature rooms, and the number of cooling rooms is greater than the number of heating rooms, it means that most rooms need to be cooled. At this time, the relationship between the temperature difference value of each room and the first temperature threshold value Tdif1 and the second temperature threshold value Tdif2 is further determined, and the target temperature and the current temperature are determined according to the relationship between the temperature difference value of each room and the first temperature threshold value Tdif1 and the second temperature threshold value Tdif2. Among them, the temperature difference value between the actual temperature and the set temperature of each room is obtained. If the temperature difference value of all rooms is greater than the first temperature threshold value Tdif1, and the temperature difference value of any room is greater than or equal to the second temperature threshold value Tdif2, then the room corresponding to the maximum temperature difference value of all rooms is obtained, and the set temperature of the room with the largest temperature difference value is used as the target temperature, and the actual temperature is used as the current temperature. Since the room with the largest temperature difference value may not be unique, when there are multiple rooms with the largest temperature difference value, the minimum set temperature among the multiple rooms is used as the target temperature, and the actual temperature of the room corresponding to the minimum set temperature is used as the current temperature. In this way, the target temperature and the current temperature can be determined, and then the air handling equipment is controlled according to the target temperature and the current temperature.

[0054] Taking the example that the temperature difference values ​​corresponding to rooms R1 and R2 are equal and both are maximum values, the actual temperature of room R1 is 25℃, the set temperature is 20℃, the actual temperature of room R2 is 26℃, the set temperature is 21℃, and the temperature difference between the actual temperature and the set temperature of the two rooms is 5℃. At this time, the minimum set temperature of 20℃ (the set temperature corresponding to room R1) is selected as the target temperature, and the actual temperature of room R1 corresponding to the minimum set temperature of 25℃ is used as the current temperature.

[0055] In some embodiments, when the number of cooling rooms is greater than or equal to the number of constant temperature rooms, the target temperature and the current temperature are determined according to the temperature difference of each room, including: if the number of cooling rooms is greater than the number of heating rooms, then when the temperature difference of any room is less than or equal to the first temperature threshold, the room with the smallest temperature difference is determined, and the maximum set temperature is determined from the room with the smallest temperature difference as the target temperature, and the actual temperature of the room corresponding to the maximum set temperature is used as the current temperature. The first temperature threshold can be calibrated according to actual conditions.

[0056] Specifically, when the number of cooling rooms is greater than or equal to the number of constant temperature rooms, and the number of cooling rooms is greater than the number of heating rooms, it means that most rooms need to be cooled. At this time, the relationship between the temperature difference value of each room and the first temperature threshold value Tdif1 is further determined, and the target temperature and current temperature are determined according to the relationship between the temperature difference value of each room and the first temperature threshold value Tdif1. Among them, the temperature difference value between the actual temperature and the set temperature of each room is obtained. If there is any room whose temperature difference value is less than or equal to the first temperature threshold value Tdif1, the room corresponding to the smallest temperature difference value of all rooms is obtained, and the set temperature of the room with the smallest temperature difference value is used as the target temperature, and the actual temperature is used as the current temperature. Since the room with the smallest temperature difference value may not be unique, when there are multiple rooms with the smallest temperature difference value, the maximum set temperature among the multiple rooms is used as the target temperature, and the actual temperature of the room corresponding to the smallest set temperature is used as the current temperature. In this way, the target temperature and the current temperature can be determined, and then the air handling equipment is controlled according to the target temperature and the current temperature.

[0057] Taking the example that the temperature difference values ​​corresponding to rooms R1 and R2 are equal and both are minimum values, the actual temperature of room R1 is 25°C and the set temperature is 20°C, the actual temperature of room R2 is 26°C and the set temperature is 21°C, and the temperature difference between the actual temperature and the set temperature of the two rooms is 5°C. At this time, the maximum set temperature of 21°C (the set temperature corresponding to room R2) is determined as the target temperature, and the actual temperature of room R2 corresponding to the maximum set temperature, 26°C, is used as the current temperature.

[0058] In some embodiments, when the number of cooling rooms is greater than or equal to the number of constant temperature rooms, the target temperature and current temperature are determined based on the temperature difference value of each room, including: if the number of cooling rooms is greater than the number of heating rooms, then when the temperature difference value of each room is greater than the first temperature threshold, the average set temperature of each room is used as the target temperature, and the average actual temperature of each room is used as the current temperature.

[0059] Specifically, when the number of cooling rooms is greater than or equal to the number of constant temperature rooms, and the number of cooling rooms is greater than the number of heating rooms, it means that most rooms need to be cooled. At this time, the relationship between the temperature difference value of each room and the first temperature threshold Tdif1 is further determined, and the target temperature and current temperature are determined according to the relationship between the temperature difference value of each room and the first temperature threshold Tdif1. Among them, the temperature difference value between the actual temperature and the set temperature of each room is obtained. If the temperature difference values ​​of all rooms are greater than the first temperature threshold Tdif1, the average value of the set temperature of each room is used as the target temperature, and the average value of the actual temperature of each room is used as the current temperature. In this way, the target temperature and the current temperature can be determined, and then the air handling equipment can be controlled according to the target temperature and the current temperature.

[0060] In some embodiments, when the number of heated rooms is greater than or equal to the number of constant temperature rooms, the target temperature and current temperature are determined based on the temperature difference of each room, including: if the number of heated rooms is greater than the number of cooled rooms, then when the temperature difference of each room is less than the third temperature threshold and the temperature difference of any room is less than or equal to the fourth temperature threshold, the room with the largest temperature difference is determined, and the maximum set temperature is determined from the room with the largest temperature difference as the target temperature, and the actual temperature of the room corresponding to the maximum set temperature is used as the current temperature, wherein the third temperature threshold is greater than the fourth temperature threshold, and the third temperature threshold and the fourth temperature threshold can be calibrated according to actual conditions.

[0061] Specifically, when the number of rooms with increased temperature is greater than or equal to the number of rooms with constant temperature, and the number of rooms with increased temperature is greater than the number of rooms with decreased temperature, it means that most rooms need to be heated. At this time, the relationship between the temperature difference value of each room and the third temperature threshold value Tdif3 and the fourth temperature threshold value Tdif4 is further determined, and the target temperature and the current temperature are determined according to the relationship between the temperature difference value of each room and the third temperature threshold value Tdif3 and the fourth temperature threshold value Tdif4. Among them, the temperature difference value between the actual temperature and the set temperature of each room is obtained. If the temperature difference value of all rooms is less than the third temperature threshold value Tdif3, and the temperature difference value of any room is less than or equal to the fourth temperature threshold value Tdif4, the room corresponding to the maximum absolute value of the temperature difference value of all rooms is obtained, and the set temperature of the room with the maximum absolute value of the temperature difference value is used as the target temperature, and the actual temperature is used as the current temperature. Since the room with the largest absolute value of the temperature difference value may not be unique, when there are multiple rooms with the largest temperature difference value, the maximum set temperature among the multiple rooms is used as the target temperature, and the actual temperature of the room corresponding to the maximum set temperature is used as the current temperature. Thereby, the target temperature and the current temperature can be determined, and then the air handling equipment can be controlled according to the target temperature and the current temperature.

[0062] Taking the example that the temperature difference values ​​corresponding to rooms R1 and R2 are equal and the absolute values ​​of the temperature difference values ​​are both maximum values, the actual temperature of room R1 is 20℃, the set temperature is 25℃, the actual temperature of room R2 is 21℃, the set temperature is 26℃, and the absolute value of the temperature difference between the actual temperature and the set temperature of the two rooms is 5℃. At this time, the maximum set temperature of 26℃ (the set temperature corresponding to room R2) is selected as the target temperature, and the actual temperature of room R2 corresponding to the maximum set temperature, 21℃, is used as the current temperature.

[0063] In some embodiments, when the number of rooms with increased temperature is greater than or equal to the number of rooms with constant temperature, the target temperature and the current temperature are determined according to the temperature difference of each room, including: if the number of rooms with increased temperature is greater than the number of rooms with decreased temperature, then when the temperature difference of any room is greater than or equal to the third temperature threshold, the room with the smallest temperature difference is determined, and the minimum set temperature is determined from the room with the smallest temperature difference as the target temperature, and the actual temperature of the room corresponding to the minimum set temperature is used as the current temperature. The third temperature threshold can be calibrated according to actual conditions.

[0064] Specifically, when the number of rooms with increased temperature is greater than or equal to the number of rooms with constant temperature, and the number of rooms with increased temperature is greater than the number of rooms with decreased temperature, it means that most rooms need to be heated. At this time, the relationship between the temperature difference value of each room and the third temperature threshold value Tdif3 is further determined, and the target temperature and current temperature are determined according to the relationship between the temperature difference value of each room and the third temperature threshold value Tdif3. Among them, the temperature difference value between the actual temperature and the set temperature of each room is obtained. If there is a room with a temperature difference value greater than or equal to the third temperature threshold value Tdif3, the room corresponding to the minimum absolute value of the temperature difference value of all rooms is obtained, and the set temperature of the room with the minimum temperature difference value is used as the target temperature, and the actual temperature is used as the current temperature. Since the room with the minimum absolute value of the temperature difference value may not be unique, when there are multiple rooms with the minimum absolute value of the temperature difference value, the minimum set temperature among the multiple rooms is used as the target temperature, and the actual temperature of the room corresponding to the minimum set temperature is used as the current temperature. In this way, the target temperature and the current temperature can be determined, and then the air handling equipment is controlled according to the target temperature and the current temperature.

[0065] Taking the example that the temperature difference values ​​corresponding to rooms R1 and R2 are equal and the absolute values ​​of the temperature difference values ​​are both minimum values, the actual temperature of room R1 is 20℃, the set temperature is 25℃, the actual temperature of room R2 is 21℃, the set temperature is 26℃, and the absolute values ​​of the temperature difference values ​​between the actual temperature and the set temperature of the two rooms are both 5℃. At this time, the minimum set temperature of 25℃ (the set temperature corresponding to room R1) is determined as the target temperature, and the actual temperature of room R1 corresponding to the minimum set temperature, 20℃, is used as the current temperature.

[0066] In some embodiments, when the number of rooms to be heated is greater than or equal to the number of rooms to be kept at a constant temperature, the target temperature and the current temperature are determined based on the temperature difference of each room, including: if the number of rooms to be heated is greater than the number of rooms to be cooled, then when the temperature difference of each room is less than a third temperature threshold, the average set temperature of each room is used as the target temperature, and the average actual temperature of each room is used as the current temperature.

[0067] Specifically, when the number of rooms to be heated is greater than or equal to the number of rooms to be kept at a constant temperature, and the number of rooms to be heated is greater than the number of rooms to be cooled, it means that most rooms need to be heated. At this time, the relationship between the temperature difference value of each room and the third temperature threshold value Tdif3 is further determined, and the target temperature and the current temperature are determined according to the relationship between the temperature difference value of each room and the third temperature threshold value Tdif3. Among them, the temperature difference value between the actual temperature and the set temperature of each room is obtained. If the temperature difference values ​​of all rooms are less than the third temperature threshold value Tdif3, the average value of the set temperature of each room is used as the target temperature, and the average value of the actual temperature of each room is used as the current temperature. In this way, the target temperature and the current temperature can be determined, and then the air handling equipment can be controlled according to the target temperature and the current temperature.

[0068] In some embodiments, the target temperature and the current temperature are determined based on the number of heating rooms, the number of cooling rooms and the number of constant temperature rooms, and also include: when the number of constant temperature rooms is greater than the number of heating rooms and the number of cooling rooms, or the number of constant temperature rooms is equal to the number of heating rooms and the number of cooling rooms, respectively, the average of the set temperatures of all constant temperature rooms is used as the target temperature, and the average of the actual temperatures of all constant temperature rooms is used as the current temperature.

[0069] Specifically, when the number of constant temperature rooms is the largest, that is, the number of constant temperature rooms is greater than the number of heating rooms, and greater than the number of cooling rooms, or the number of heating rooms, cooling rooms and constant temperature rooms are the same, it means that most rooms need to be kept at a constant temperature. At this time, the target temperature and current temperature can be determined based on the constant temperature demand, that is, the average of the set temperatures of all constant temperature rooms is used as the target temperature, and the average of the actual temperatures of all constant temperature rooms is used as the current temperature. In this way, the target temperature and current temperature can be determined, and then the air handling equipment can be controlled based on the target temperature and current temperature.

[0070] In some embodiments, when the number of cooling rooms is equal to the number of heating rooms and is greater than the number of constant temperature rooms, the method also includes: setting the return air temperature of the air handling equipment as the target temperature, and setting the return air humidity of the air handling equipment as the target humidity, so as to control the air handling equipment to operate in fresh air ventilation mode.

[0071] Specifically, in the aforementioned embodiments, it has been explained how to determine the target temperature and the current temperature based on the cooling demand, the heating demand and the constant temperature demand. In addition to these three situations, there is also a situation where the number of cooling rooms is equal to the number of heating rooms, and the number of heating rooms and the number of cooling rooms are both greater than the number of constant temperature rooms. At this time, the temperature and humidity of each room are not directly involved in the energy demand control. The return air temperature of the air treatment equipment (fresh air system) is directly used as the target temperature, and the return air humidity of the air treatment equipment (fresh air system) is used as the target humidity. That is, the fresh air ventilation mode of the air treatment equipment (fresh air system) is turned on. This mode has no heat exchange demand, only introduces outdoor fresh air, and discharges indoor air at the same time.

[0072] It can be seen from the above embodiments that the present application determines the target temperature and the current temperature according to the relationship between the number of cooling rooms, the number of heating rooms and the number of constant temperature rooms, as well as the temperature difference value of each room, and then controls the energy demand of the air handling equipment according to the target temperature and the current temperature, thereby balancing the needs of each room, making the environment in each room more comfortable, and at the same time improving the energy efficiency of the entire machine.

[0073] Figure 4 FIG. 1 is a flow chart of a method for adjusting environmental parameters of multiple rooms according to a third embodiment of the present invention. Figure 4 , the multi-room environmental parameter adjustment method may include:

[0074] S310, obtaining the actual humidity and the set humidity of each room.

[0075] For example, refer to Figure 1 , rooms R1, R2 to Rn are all equipped with a human-machine interface operator and at least one humidity sensor. For example, room Rn is equipped with operator Pn and humidity sensor Dn. In room Rn, when the user selects the fresh air system to operate in intelligent mode through operator Pn, the set humidity of room Rn can be directly set to Dsn. At the same time, the relative humidity of room Rn is obtained through humidity sensor Dn. According to the relationship between the actual temperature and relative humidity in the room, the actual humidity Dn of room Rn can be calculated. It should be noted that the actual humidity and set humidity of rooms R1 to Rn-1 are obtained in the same way as those of room Rn, and no examples are given here one by one.

[0076] S320, determining the number of dehumidification rooms, the number of humidification rooms, and the number of constant humidity rooms according to the actual humidity and the set humidity of each room.

[0077] For example, when the set humidity of the current room is greater than the actual humidity, it is determined that the room needs to be humidified, that is, the room is a humidified room; when the set humidity of the current room is less than the actual humidity, it is determined that the room needs to be dehumidified, that is, the room is a dehumidified room; when the set humidity of the current room is equal to the actual humidity, it is determined that the room needs to be constant humidity, that is, the room is a constant humidity room. The fresh air system collects the actual humidity and set humidity of each room, and compares the actual humidity and the set humidity of each room to determine the situation of each room, and finally determines the number of humidified rooms, dehumidified rooms, and constant humidity rooms.

[0078] S330, determining the target humidity and the current humidity according to the number of dehumidification rooms, the number of humidification rooms, and the number of constant humidity rooms.

[0079] Specifically, after the fresh air system determines the number of humidified rooms, dehumidified rooms and constant humidity rooms, it determines the energy requirements of the fresh air system when working in intelligent mode by comparing the number of humidified rooms, dehumidified rooms and constant humidity rooms, thereby determining the target humidity and current humidity.

[0080] Exemplarily, when the number of dehumidification rooms is the largest, or the number of dehumidification rooms and the number of constant humidity rooms are relatively large, and the number of humidification rooms is small, it can be considered that most rooms need to be dehumidified, and the target humidity and current humidity can be determined by the dehumidification demand. When the number of humidification rooms is the largest, or the number of humidification rooms and the number of constant humidity rooms are relatively large, and the number of dehumidification rooms is small, it can be considered that most rooms need to be humidified, and the target humidity and current humidity can be determined by the humidification demand. When the number of constant humidity rooms is large, and the number of dehumidification rooms and the number of humidification rooms are small, it can be considered that most rooms need to be constant humidity, and the target humidity and current humidity can be determined by the constant humidity demand. In addition, the humidity value of each room is compared with a preset threshold value, and the target humidity and current humidity are determined by judging the relationship between the humidity value and the preset threshold value.

[0081] S340, controlling the air handling equipment to adjust the humidity according to the target humidity and the current humidity.

[0082] Specifically, when the intelligent mode is selected, by comparing the number of dehumidification rooms, the number of humidification rooms and the number of constant humidity rooms, the energy demand of the air treatment equipment (fresh air system) is determined to be dehumidification, humidification and constant humidity, and the target humidity and current humidity are determined under different energy demands. At the same time, the fresh air system intelligently adjusts the indoor environment according to the target humidity and current humidity.

[0083] In this way, by conducting statistical analysis on the actual humidity and set humidity in each room, the target humidity and current humidity can be obtained, the energy demand control of the air handling equipment can be achieved, and the indoor humidity can be intelligently adjusted to make the indoor environment more comfortable. At the same time, the needs of each room can be balanced to improve the energy efficiency of the entire machine.

[0084] In some embodiments, the target humidity and the current humidity are determined based on the number of dehumidification rooms, the number of humidification rooms and the number of constant humidity rooms, including: when the number of dehumidification rooms is greater than the number of humidification rooms, and the number of dehumidification rooms is greater than or equal to the number of constant humidity rooms, the room with the maximum humidity difference is determined based on the humidity difference of each room, and the maximum actual humidity is determined from the room with the maximum humidity difference as the current humidity, and the set humidity of the room corresponding to the maximum actual humidity is used as the target humidity.

[0085] Specifically, when the number of dehumidified rooms is greater than the number of humidified rooms, and the number of dehumidified rooms is greater than or equal to the number of constant humidity rooms, it means that most rooms need to be dehumidified. At this time, the humidity difference between the actual humidity and the set humidity of each room can be analyzed based on the dehumidification demand, and the room with the largest humidity difference among all rooms can be obtained. The set humidity of the room with the largest humidity difference is used as the target humidity, and the actual humidity of the room with the largest humidity difference is used as the current humidity. Since there is no unique room with the largest humidity difference, when there are multiple rooms with the largest humidity difference, the maximum actual humidity among the multiple rooms is used as the current humidity, and the set humidity of the room corresponding to the maximum actual humidity is used as the target humidity.

[0086] Taking the example that the humidity differences corresponding to rooms R1 and R2 are equal and both are maximum values, the actual humidity of room R1 is 9g / kg, the set humidity is 7g / kg, the actual humidity of room R2 is 8g / kg, and the set humidity is 6g / kg. The humidity difference between the actual humidity and the set humidity of the two rooms is 2g / kg. At this time, the maximum actual humidity of 9g / kg (the actual humidity of room R1) is determined as the current humidity from the room with the largest humidity difference, and the set humidity of 7g / kg corresponding to the maximum actual humidity in room R1 is used as the target humidity.

[0087] In some embodiments, the target humidity and the current humidity are determined based on the number of dehumidified rooms, the number of humidified rooms, and the number of constant humidity rooms, including: when the number of humidified rooms is greater than the number of dehumidified rooms, and the number of humidified rooms is greater than or equal to the number of constant humidity rooms, the room with the largest humidity difference is determined based on the humidity difference of each room, and the minimum actual humidity is determined from the room with the largest humidity difference as the current humidity, and the set humidity of the room corresponding to the minimum actual humidity is used as the target humidity.

[0088] Specifically, when the number of humidification rooms is greater than the number of dehumidification rooms, and the number of humidification rooms is greater than or equal to the number of constant humidity rooms, it means that most rooms need humidification. At this time, the humidity difference between the actual humidity and the set humidity of each room can be analyzed according to the humidification demand, and the room corresponding to the maximum absolute value of the humidity difference of all rooms is obtained. The set humidity of the room with the maximum absolute value of the humidity difference is used as the target humidity, and the actual humidity of the room with the maximum absolute value of the humidity difference is used as the current humidity. Since there is no unique room with the maximum absolute value of the humidity difference, when there are multiple rooms with the maximum absolute value of the humidity difference, the minimum actual humidity among the multiple rooms is used as the current humidity, and the set humidity of the room corresponding to the minimum actual humidity is used as the target humidity.

[0089] Taking the case where the humidity differences corresponding to rooms R1 and R2 are equal and the absolute values ​​of the humidity differences are both maximum values, the actual humidity of room R1 is 7g / kg, the set humidity is 9g / kg, the actual humidity of room R2 is 6g / kg, and the set humidity is 8g / kg. The absolute values ​​of the humidity differences between the room humidity and the set humidity of the two rooms are both 2g / kg. At this time, the minimum actual humidity of 6g / kg (the actual humidity of room R2) is determined as the current humidity from the room with the largest absolute value of the humidity difference, and the set humidity of 8g / kg corresponding to the minimum actual humidity in room R2 is used as the target humidity.

[0090] In some embodiments, the target humidity and the current humidity are determined based on the number of dehumidification rooms, the number of humidification rooms and the number of constant humidity rooms, including: when the number of constant humidity rooms is greater than the number of humidification rooms and the number of dehumidification rooms, or the number of constant humidity rooms is equal to the number of humidification rooms and the number of dehumidification rooms, respectively, taking the average set humidity of all constant humidity rooms as the target humidity, and taking the average actual humidity of all constant humidity rooms as the current humidity.

[0091] Specifically, when the number of constant humidity rooms is the largest, or the number of dehumidification rooms, humidification rooms and constant humidity rooms is the same, it means that the number of rooms that require constant humidity is the largest, that is, the target humidity and current humidity are determined based on the constant humidity demand. For example, the average value of the set humidity of all constant humidity rooms is used as the target humidity, and the average value of the actual humidity of all constant humidity rooms is used as the current humidity. In this way, the target humidity and current humidity can be determined, and then the air handling equipment can be controlled based on the target humidity and current humidity.

[0092] In some embodiments, the target humidity and the current humidity are determined according to the number of dehumidified rooms, the number of humidified rooms, and the number of constant humidity rooms, including: when the number of dehumidified rooms is equal to the number of humidified rooms and is greater than the number of constant humidity rooms, if the actual humidity of any room is greater than the first humidity threshold, the room with the largest humidity difference is determined according to the humidity difference of each room, and the maximum actual humidity is determined from the room with the largest humidity difference as the current humidity, and the set humidity of the room corresponding to the maximum actual humidity is used as the target humidity. The first humidity threshold can be calibrated according to actual conditions.

[0093] Specifically, in the aforementioned embodiments, it has been explained how to determine the target humidity and the current humidity based on the dehumidification demand, the humidification demand and the constant humidity demand. In addition to these three situations, there is also a situation where the number of dehumidification rooms is equal to the number of humidification rooms, and the number of dehumidification rooms and the number of humidification rooms are both greater than the number of constant humidity rooms. At this time, the target humidity and the current humidity are determined based on the humidity value of each room.

[0094] If the actual humidity of any room among all the rooms is greater than the first humidity threshold Ddif1, the humidity difference between the actual humidity and the set humidity of each room is determined. When there is only one room with the largest absolute value of the humidity difference, the set humidity of this room is directly used as the target humidity, and the actual humidity is used as the current humidity; when there are multiple rooms with the largest absolute value of the humidity difference, the maximum actual humidity among the multiple rooms is used as the current humidity, and the set humidity of the room corresponding to the maximum actual humidity is used as the target humidity.

[0095] Taking the example that the humidity differences corresponding to room R1 and room R2 are equal and the absolute values ​​of the humidity differences are both maximum values, the actual humidity of room R1 is 9g / kg, the set humidity is 7g / kg, the actual humidity of room R2 is 8g / kg, and the set humidity is 6g / kg. The absolute value of the humidity difference between the actual humidity and the set humidity of the two rooms is 2g / kg. At this time, the maximum actual humidity of 9g / kg (the actual humidity of room R1) is determined as the current humidity from the room with the largest absolute value of the humidity difference, and the set humidity of 7g / kg corresponding to the maximum actual humidity in room R1 is used as the target humidity.

[0096] If the actual humidity of any room is less than the second humidity threshold, and the actual humidity of each room is less than the third humidity threshold, the room with the maximum humidity difference is determined according to the humidity difference of each room, and the minimum actual humidity is determined from the room with the maximum humidity difference as the current humidity, and the set humidity of the room corresponding to the minimum actual humidity is used as the target humidity, wherein the second humidity threshold is less than the third humidity threshold, and the third humidity threshold is less than the first humidity threshold, and the second humidity threshold and the third humidity threshold can be calibrated according to actual conditions.

[0097] Specifically, when the actual humidity in any room is less than the second humidity threshold Ddif2, and the actual humidity in each room is less than the third humidity threshold Ddif3, the humidity difference between the room humidity and the set humidity in each room is determined. When there is only one room with the largest absolute value of the humidity difference, the set humidity of this room is directly used as the target humidity, and the actual humidity is used as the current humidity; when there are multiple rooms with the largest absolute value of the humidity difference, the minimum actual humidity among the multiple rooms is used as the current humidity, and the set humidity of the room corresponding to the minimum actual humidity is used as the target humidity.

[0098] Taking the example that the humidity differences corresponding to room R1 and room R2 are equal and the absolute values ​​of the humidity differences are both maximum values, the actual humidity of room R1 is 7g / kg, the set humidity is 9g / kg, the actual humidity of room R2 is 6g / kg, and the set humidity is 8g / kg. The absolute value of the difference between the actual humidity and the set humidity of the two rooms is 2g / kg. At this time, the minimum actual humidity of 6g / kg (the actual humidity of room R2) is determined as the current humidity from the room with the largest absolute value of the humidity difference, and the set humidity of 8g / kg corresponding to the minimum actual humidity in room R1 is used as the target humidity.

[0099] If the actual humidity of any room is less than or equal to the first humidity threshold and greater than or equal to the third humidity threshold, or the actual humidity of each room is less than or equal to the second humidity threshold, the average actual humidity of all humidified rooms and all dehumidified rooms is taken as the current humidity, and the set humidity average of all humidified rooms and all dehumidified rooms is taken as the target humidity.

[0100] In the above embodiment, the method for selecting the current humidity and the target humidity has been described for the two cases where the actual humidity of any room is greater than the first humidity threshold Ddif1 and the actual humidity of any room is less than the second humidity threshold Ddif2, and the actual humidity of each room is less than the third humidity threshold Ddif3. In addition to these two cases, that is, when the actual humidity of any room is less than or equal to the first humidity threshold and greater than or equal to the third humidity threshold, or the actual humidity of each room is less than or equal to the second humidity threshold, the average value of the actual humidity of all humidified rooms and all dehumidified rooms is directly used as the current humidity, and the average value of the set humidity of all humidified rooms and all dehumidified rooms is used as the target humidity.

[0101] Therefore, through the above embodiments, it can be seen that the present application determines the target humidity and the current humidity according to the relationship between the number of dehumidification rooms, the number of humidification rooms and the number of constant humidity rooms, as well as the humidity value of each room, and then controls the energy demand of the air handling equipment according to the target humidity and the current humidity, thereby balancing the needs of each room, making the environment of each room more comfortable, and at the same time improving the energy efficiency of the entire machine.

[0102] When the air handling equipment (fresh air system) is selected to work in intelligent mode, the data to be controlled is determined according to the number of rooms to be heated, the number of rooms to be cooled, and the number of rooms to be kept at a constant temperature. For a specific example, refer to Figure 5 , the method for adjusting the environmental parameters of multiple rooms may also include:

[0103] S401, determine whether the number of cooling rooms>the number of heating rooms, and the number of constant temperature rooms≤the number of cooling rooms. If yes, execute S407; if not, execute S402.

[0104] S402, determine whether the number of heating rooms>the number of cooling rooms, and the number of constant temperature rooms≤the number of heating rooms. If yes, execute S406; if no, execute S403.

[0105] Exemplarily, when the number of heated rooms is the largest and the number of heated rooms is equal to the number of constant temperature rooms, it means that most rooms need to be heated. In this case, S406 is executed, otherwise S403 is executed.

[0106] S403, determine whether the number of constant temperature rooms is the largest, or the number of temperature reduction / increase / constant temperature rooms are the same. If yes, execute S405; if no, execute S404.

[0107] Exemplarily, when the number of constant temperature rooms is the largest, or the number of warm rooms, the number of cooling rooms and the number of constant temperature rooms are the same, it means that most rooms need to be kept at a constant temperature. In this case, S405 is executed, otherwise S404 is executed.

[0108] S404, the target temperature and the target humidity are the return air temperature and the return air humidity content respectively.

[0109] In addition to the judgment conditions of S401, S402 and S403, there is a situation where the number of cooling rooms is equal to the number of heating rooms and is greater than the number of constant temperature rooms. At this time, the temperature and humidity of each room do not directly participate in the energy demand control. The return air temperature of the air treatment equipment (fresh air system) is directly used as the target temperature, and the return air humidity of the air treatment equipment (fresh air system) is used as the target humidity. That is, the fresh air ventilation mode of the air treatment equipment (fresh air system) is turned on. This mode has no heat exchange demand, only introduces outdoor fresh air, and exhausts indoor air at the same time.

[0110] S405, the target temperature and the current temperature are averaged in the constant temperature room.

[0111] When most rooms need to be kept at a constant temperature, the average set temperature of all the constant temperature rooms is used as the target temperature, and the average actual temperature of all the constant temperature rooms is used as the current temperature.

[0112] S406, processing of the source of the heating demand setting temperature.

[0113] When the energy demand in most rooms is heating, the data for energy control, namely the target temperature and the current temperature, is determined based on the heating demand.

[0114] S407, processing the source of the cooling demand setting temperature.

[0115] When the energy demand in most rooms is cooling, the data for energy control, namely the target temperature and the current temperature, is determined based on the cooling demand.

[0116] In this way, by comparing the number of rooms that need to be cooled, heated, and kept at a constant temperature, the air handling equipment (fresh air system) is controlled to determine the data that needs to be controlled in cooling, heating, constant temperature, or fresh air ventilation mode, thereby avoiding the situation where the control of individual rooms is ignored.

[0117] When most rooms require cooling, the data for energy demand control will be determined based on the cooling demand. For a specific example, refer to Figure 6 , step S407 may include:

[0118] S501, determine whether the room temperature difference between all rooms and the set temperature △T>Tdif1, and whether any room △T≥Tdif2 is established. If yes, execute S505; if not, execute S502.

[0119] S502, determine whether the temperature difference value △T≤Tdif1 of any room is established. If yes, execute S504; if not, execute S503.

[0120] S503, taking the average value of all room-related data.

[0121] Exemplarily, in addition to the judgment conditions of S501 and S502, there is a situation where the temperature difference △T of any room is greater than the first temperature threshold Tdif1. At this time, the average set temperature of each room is used as the target temperature, and the average actual temperature of each room is used as the current temperature.

[0122] S504, select the room with the highest set temperature among the rooms with the smallest ΔT.

[0123] Exemplarily, when the judgment condition of S502 is met, the difference △T between the room temperature and the set temperature of each room is determined. If the room with the smallest temperature difference △T is unique, the set temperature of this room is determined as the target temperature, and the actual temperature is used as the current temperature. If the room with the smallest temperature difference △T is not unique, the maximum set temperature in the room with the smallest temperature difference △T is determined as the target temperature, and the actual temperature of the room corresponding to the maximum set temperature is used as the current temperature.

[0124] S505, select the room with the lowest set temperature among the rooms with the largest ΔT.

[0125] Exemplarily, when the judgment condition of S501 is met, the difference △T between the room temperature and the set temperature of each room is determined. If the room with the largest temperature difference △T is unique, the set temperature of this room is determined as the target temperature, and the actual temperature is determined as the current temperature. If the room with the smallest temperature difference △T is not unique, the minimum set temperature in the room with the largest temperature difference is determined as the target temperature, and the actual temperature of the room corresponding to the minimum set temperature is determined as the current temperature.

[0126] In this way, when cooling is required, the air handling equipment (fresh air system) determines the data that needs to be controlled by judging the threshold range of the difference between the room temperature of each room and the set temperature, thereby avoiding over-adjustment.

[0127] When the energy demand in most rooms is heating, the data of energy demand control will be determined by heating demand. As a specific example, refer to Figure 7 , step S406 may include:

[0128] S601, determine whether the temperature difference between the room temperature of all rooms and the set temperature △T<Tdif3, and whether any room △T≤Tdif4 is established. If yes, execute S605; if not, execute S602.

[0129] S602, determine whether △T≥Tdif3 is true for any room. If yes, execute S604; if no, execute S603.

[0130] S603, taking the average value of all room-related data.

[0131] Exemplarily, in addition to the judgment conditions of S601 and S602, there is a situation where the temperature difference △T of any room is less than the third temperature threshold Tdif3. At this time, the average set temperature of each room is used as the target temperature, and the average actual temperature of each room is used as the current temperature.

[0132] S604, select the room with the lowest set temperature among the -△T minimum rooms.

[0133] Exemplarily, when the judgment condition of S602 is met, the difference △T between the room temperature and the set temperature of each room is determined. If the room with the smallest temperature difference value -△T is unique, the set temperature of this room is determined as the target temperature, and the actual temperature is used as the current temperature. If the room with the smallest temperature difference value -△T is not unique, the minimum set temperature in the room with the smallest temperature difference value is determined as the target temperature, and the actual temperature of the room corresponding to the minimum set temperature is used as the current temperature.

[0134] S605, select the room with the highest set temperature among the -△T maximum rooms.

[0135] Exemplarily, when the judgment condition of S601 is met, the difference △T between the room temperature and the set temperature of each room is determined. If the room with the largest temperature difference value -△T is unique, the set temperature of this room is determined as the target temperature, and the actual temperature is used as the current temperature.

[0136] In this way, when heating is required, the air handling equipment (fresh air system) determines the data that needs to be controlled by judging the threshold range of the difference between the room temperature of each room and the set temperature, thereby avoiding over-adjustment.

[0137] When the air handling equipment (fresh air system) is selected to work in intelligent mode, the data to be controlled is determined according to the number of dehumidification rooms, the number of humidification rooms, and the number of constant humidity rooms. As a specific example, refer to Figure 8 , the method for adjusting the environmental parameters of multiple rooms may also include:

[0138] S701, determine whether the number of dehumidification rooms> the number of humidification rooms, and the number of constant humidity rooms≤ the number of dehumidification rooms. If yes, execute S711; if not, execute S702.

[0139] Exemplarily, when the number of dehumidification rooms is the largest and the number of dehumidification rooms is equal to the number of constant humidity rooms, it means that most rooms need to be dehumidified. In this case, S711 is executed, otherwise S702 is executed.

[0140] S702, determine whether the number of humidification rooms>the number of dehumidification rooms, and the number of constant humidity rooms≤the number of humidification rooms. If yes, execute S710; if no, execute S703.

[0141] Exemplarily, when the number of humidification rooms is the largest and the number of humidification rooms is equal to the number of constant humidity rooms, it means that most rooms need to be humidified, and S710 is executed at this time, otherwise S703 is executed.

[0142] S703, determine whether the number of constant humidity rooms is the largest, or whether the number of dehumidification / addition / constant humidity rooms is the same. If yes, execute S709; if no, execute S704.

[0143] Exemplarily, when the number of constant humidity rooms is the largest, or the number of dehumidification rooms, the number of humidification rooms and the number of constant humidity rooms are the same, it means that most rooms need to be constant humidity. In this case, S709 is executed, otherwise S704 is executed.

[0144] S704, determine whether the actual humidity of any room is greater than Ddif1. If yes, execute S708; if no, execute S705.

[0145] S705, determine whether the actual humidity of any room is less than Ddif2, and the actual humidity of all rooms is less than Ddif3. If yes, execute S707; if no, execute S706.

[0146] S706, taking the average value of the actual humidity of each dehumidification room and humidification room.

[0147] Exemplarily, in addition to the judgment conditions of S704 and S705, there is a situation where the third humidity threshold Ddif3 ≤ the actual humidity of any room ≤ the first humidity threshold Ddif1, or the actual humidity of each room ≤ the second humidity threshold Ddif2. At this time, the average actual humidity of all humidified rooms and all dehumidified rooms is directly used as the current humidity, and the set humidity average of all humidified rooms and all dehumidified rooms is used as the target humidity.

[0148] S707, select the room with the lowest actual humidity among the -△D maximum humidity differences.

[0149] Exemplarily, when the judgment condition of S705 is met, the difference between the room humidity and the set humidity of each room is determined to be △D. When there is only one room with the largest humidity difference -△D, the set humidity of this room is directly used as the target humidity, and the actual humidity is used as the current humidity. When there is more than one room with the largest humidity difference -△D, the minimum actual humidity is determined from the room with the largest humidity difference -△D as the current humidity, and the set humidity of the room corresponding to the minimum actual humidity is used as the target humidity.

[0150] S708, select the room with the highest actual humidity among the △D maximum humidity differences.

[0151] Exemplarily, when judgment condition S704 is met, the difference △D between the room humidity and the set humidity of each room is determined. When there is only one room with the largest humidity difference △D, the set humidity of this room is directly used as the target humidity, and the actual humidity is used as the current humidity. When there is more than one room with the largest humidity difference △D, the maximum actual humidity is determined from the room with the largest humidity difference △D as the current humidity, and the set humidity of the room corresponding to the maximum actual humidity is used as the target humidity.

[0152] S709, taking the average value of the actual humidity of each constant humidity room.

[0153] Exemplarily, when judgment condition S703 is met, the target humidity and the current humidity are determined based on the constant humidity requirement, that is, the average set humidity of all constant humidity rooms is used as the target humidity, and the average actual humidity of all constant humidity rooms is used as the current humidity.

[0154] S710, select the room with the lowest actual humidity among the rooms with the largest -ΔD.

[0155] Exemplarily, when judgment condition S702 is met, the target humidity and current humidity are determined based on the humidification demand, and the difference between the room humidity and the set humidity of each room is determined as △D. When there is only one room with the largest humidity difference -△D, the set humidity of this room is directly used as the target humidity, and the actual humidity is used as the current humidity. When there is more than one room with the largest humidity difference -△D, the minimum actual humidity is determined from the room with the largest humidity difference -△D as the current humidity, and the set humidity of the room corresponding to the minimum actual humidity is used as the target humidity.

[0156] S711, select the room with the highest actual humidity among the rooms with the largest ΔD.

[0157] Exemplarily, when judgment condition S701 is met, the target humidity and current humidity are determined based on the dehumidification demand, and the difference between the room humidity and the set humidity of each room is determined as △D. When there is only one room with the largest humidity difference △D, the set humidity of this room is directly used as the target humidity, and the actual humidity is used as the current humidity. When there is more than one room with the largest humidity difference △D, the maximum actual humidity in the room with the largest humidity difference △D is determined as the current humidity, and the set humidity of the room corresponding to the maximum actual humidity is used as the target humidity.

[0158] In this way, by comparing the number of dehumidification, humidification and constant humidity rooms, the air handling equipment (fresh air system) is controlled to determine the data that needs to be controlled under the needs of dehumidification, humidification and constant humidity, so as to avoid the situation where the control of individual rooms is ignored. At the same time, by judging the threshold range of the difference between the actual humidity and the set humidity in each room, the data that needs to be controlled is determined to avoid over-adjustment.

[0159] In summary, according to the multi-room environmental parameter adjustment method of the embodiment of the present invention, the number of heating rooms, the number of cooling rooms, and the number of constant temperature rooms are determined according to the actual temperature and set temperature of each room, and the target temperature and the current temperature are determined according to the number of heating rooms, the number of cooling rooms, and the number of constant temperature rooms, and the air handling equipment is energy demand controlled according to the target temperature and the current temperature. Therefore, by statistically analyzing the actual temperature and the set temperature of each room, the energy demand control of the air handling equipment is realized, so that the needs of each room can be balanced, so that the environment of each room is more comfortable, and the energy efficiency of the whole machine can be improved.
