Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to an embodiment of the present invention, there is provided a control apparatus of a multi air conditioning system. Referring to fig. 1, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The control device of the multi-air-conditioning system is applied to the load output control of multiple zones corresponding to the multi-air-conditioning system, and the control device of the multi-air-conditioning system in the load output control of the multiple zones can comprise: the device comprises a setting unit, a determining unit and a control unit.

In an alternative example, the setting unit may be configured to control the multiple air conditioning systems to be set in a manner of sharing the same air duct, that is, to control the air ducts of the air conditioning systems in the multiple air conditioning systems to be set in a sharing manner. The multi-air-conditioning system may include more than two air-conditioning systems, and the air ducts of the more than two air-conditioning systems are arranged in a shared manner, that is, the more than two air-conditioning systems can share the ventilation air duct.

For example: and a plurality of air conditioning systems carry out output sharing in a way of sharing an air duct. Specifically, when the air conditioner is installed in a project, a plurality of air conditioning systems can share the air duct. The air ducts are shared by gathering the air outlets of all units together through the air pipes, and then controlling the air outlet flow direction to different areas through the air valves.

In an alternative example, the determination unit may be configured to determine a theoretical output load of the multi-air conditioning system.

Alternatively, the determining unit determines the theoretical output load of the multi-air conditioning system, and may include:

the determining unit may be further configured to uniformly receive and compile the temperature controllers and the air valves of all the regions corresponding to the multi-air-conditioning system, that is, the temperature controllers and the air valves of all the regions are uniformly received and compiled to be managed by one region-controlled multi-air-conditioning system.

More optionally, the determining unit may perform unified management of the temperature controllers and the air valves of all the zones corresponding to the multi-air conditioning system, where the unified management may include at least one of the following management situations:

the first scenario for compilation management: the determining unit may be further specifically configured to determine, according to the number of air conditioning systems in the multi-air conditioning system and the maximum number of areas corresponding to areas before the air duct is not shared by the multi-air conditioning system, the number of areas that can be controlled after the air duct is shared by the multi-air conditioning system.

For example: when n sets of air conditioning systems are judged, the area control multi-air conditioning system widens the existing controllable maximum area number m to be n m, wherein m and n are natural numbers.

Second compilation management scenario: the determining unit may be further configured to perform unified management of the temperature controllers of the air conditioning systems in the multi-air conditioning system according to the arrangement sequence of the air conditioning systems in the multi-air conditioning system.

For example: the temperature controllers are collected and numbered uniformly. Specifically, the management of the temperature controllers of each set of system is performed, and if the first air conditioning system 21 is connected with 2 zone temperature controllers, the numbers are defined as No. 1 and No. 2; if the second air conditioning system 22 is connected with 4 zone thermostats, the numbers are defined as 3, 4, 5, 6 on the basis of the first air conditioning system 21, and so on.

The third scenario for revenue management: the determining unit may be further configured to perform unified management of the air valves of the air conditioning systems in the multi-air conditioning system according to the arrangement sequence of the air conditioning systems in the multi-air conditioning system and corresponding to the arrangement sequence of the temperature controllers of the air conditioning systems in the multi-air conditioning system.

Therefore, the temperature controllers and the air valves of all the areas corresponding to the multi-air-conditioning system are managed in a unified manner, the output load can be supplied based on the starting requirement according to the management mode, the reliable supply of the starting requirement is guaranteed, and the energy waste caused by overload output is avoided.

The determining unit may be specifically configured to determine a total output load of the multi-air conditioning system.

More optionally, the determining unit determines a total output load of the multi air conditioner system, and may include: the determining unit may be specifically configured to calculate, according to an area size of each region corresponding to the multi-air-conditioning system, a total output load required by all the regions corresponding to the multi-air-conditioning system; and determining the total output load required by all the areas corresponding to the air conditioning systems as the total output load of the multi-air conditioning system.

For example: and calculating the maximum allowable output load Tmax according to the total area of the region. Specifically, when receiving and compiling, the total output load of the air conditioners required by all the regions is calculated according to the area size of each region, the maximum allowable output load Tmax of the whole set of region control system is determined, and overload output in subsequent control is avoided.

Therefore, the total output load of the multi-air-conditioning system is determined by the determining unit, the output load capacity of each air-conditioning system in the multi-air-conditioning system can be determined within the capacity range of the total output load, and the reliability and the safety of supplying the output load based on the starting requirement can be ensured.

The determining unit may be specifically configured to determine the output load capacity of each air conditioning system in the multi-air conditioning system within a capacity range of the total output load of the multi-air conditioning system. The output capacity grading among the air conditioning systems can be divided according to actual conditions, for example, the back-and-forth switching among the air conditioning systems is reduced as much as possible.

More optionally, the determining unit determines the output load capacity of each air conditioning system in the multi-air conditioning system, and may include: the determining unit may be specifically configured to determine an output load capacity of a single air conditioning system in the multi-air conditioning system, and determine an output load capacity of a combined air conditioning system of two or more single air conditioning systems in the multi-air conditioning system.

Wherein, the first to nth air conditioning systems may include: a single air conditioning system of a multi-air conditioning system, and/or a combined air conditioning system of two or more single air conditioning systems of a multi-air conditioning system.

The regions corresponding to the first to nth air conditioning systems may include: the single area corresponding to a single air-conditioning system in the multi-air-conditioning system and/or the collocation area corresponding to a combined air-conditioning system of more than two single air-conditioning systems in the multi-air-conditioning system.

Specifically, the single air conditioner output load of a single air conditioner system in the multi-air conditioner system is determined, the combined air conditioner output load of each combined air conditioner system after combination between more than two air conditioner systems in the multi-air conditioner system is determined, and the area output load of each area after single area and multi-area collocation in an area controlled by the multi-air conditioner system is determined. That is, the single air conditioner output load capacities of the air conditioning systems in the multi-air conditioning system are arranged according to a set sequence, and the area output load capacities of the areas after the single area and the multiple areas are matched are arranged according to the set sequence; and arranging the combined air conditioner output load capacities of the combined air conditioner systems combined among more than two air conditioner systems in the multi-air conditioner system according to a set sequence.

For example: sequencing and numbering the air conditioning systems according to the sequence of the output load capacity T from small to small, and recording as A1-An; and sorting the output load capacity T of single-region and multi-region collocation from small to large, and recording as T1-Tmax. Specifically, the air conditioning systems may be numbered according to the output capacity from small to large: a1 and A2 … … An, the output load capacities are T1 and T2 … … Tn respectively; synchronously, the sum of the output load capacities obtained by combining a plurality of systems is calculated, and sorting processing is carried out from small to large and is marked as T (n +1) … … Tmax.

Therefore, the starting requirement can be supplied according to the output load capacity by determining the output load capacity of each air-conditioning system in the multi-air-conditioning system, the supply of the starting requirement is ensured, and energy is not wasted.

The determining unit may be further configured to arrange the air conditioning systems into first to nth air conditioning systems in order of increasing output load capacities of the air conditioning systems. The output load capacities of the areas corresponding to the first to nth air conditioning systems are correspondingly from the first output load to the total output load.

Specifically, within the capacity range of the total output load of the multi-air-conditioning system, determining the air-conditioning output load of each air-conditioning system in the multi-air-conditioning system, and arranging the air-conditioning systems into a first air-conditioning system to an nth air-conditioning system according to the sequence from small to large of the capacity of the air-conditioning output load; and determining the regional output loads of the regions corresponding to the first to nth air-conditioning systems in the multi-air-conditioning system within the capacity range of the total output load of the multi-air-conditioning system, and arranging the regions into the first to total output loads according to the sequence from small to large of the capacity of the regional output loads. n is a natural number.

Therefore, by determining the theoretical output load of the multi-air-conditioning system, the starting or closing of the multi-air-conditioning system can be adjusted based on the theoretical output load of the multi-air-conditioning system so as to supply the starting requirement, and the user requirement is met.

In an optional example, the determining unit may be further configured to determine, in a case where the multi-air conditioning system has a start-up demand, a total load required by an area having the start-up demand. For example: and in the comprehensive management of the air conditioning system according to the requirements of each area, when the unit has a starting requirement, counting the total load X required by the area with the requirement.

In an optional example, the control unit may be configured to control at least some air conditioning systems in the multi-air conditioning system to be turned on according to a total load required by an area with a start-up requirement and a theoretical output load of the multi-air conditioning system, where the at least some air conditioning systems are capable of meeting the total load required by the area with the start-up requirement, so as to utilize the total load required by the area with the start-up requirement of the at least some air conditioning systems in the multi-air conditioning system.

Therefore, in multi-zone control, intelligent control of all zones is realized through output sharing of multiple sets of air conditioning systems and unified allocation of each zone; therefore, the optimized output of a plurality of sets of air conditioning systems in multi-region control can be realized, and energy waste is avoided.

Optionally, the control unit controls at least part of air conditioning systems in the multi-air conditioning system to be turned on according to a total load required by an area with a starting requirement and a theoretical output load of the multi-air conditioning system, where the at least part of air conditioning systems can meet the total load required by the area with the starting requirement, and the control unit may include any one of the following control situations:

the first control scenario: the control unit may be further configured to, for a single air conditioning system, that is, for the first to nth air conditioning systems, control the nth air conditioning system to be turned on if the total load required by the area with the start-up demand is less than or equal to the nth output load. For example: and when the total load X required by the area with the n-1 th output load capacity T (n-1) < the demand is less than or equal to the n-th output load capacity Tn, starting the air conditioning system An with the n-th output capacity to meet the demand of the area.

For example: if the total load required by the area with the starting requirement is less than or equal to the first output load, controlling the first air conditioning system to be started; if the total load X required by the required area is less than or equal to the first output load capacity T1, the air conditioning system A1 corresponding to the first output capacity is started to meet the requirement of the area.

For another example: if the total load required by the area with the starting requirement is greater than the first output load and less than or equal to the second output load, controlling the second air conditioning system to be started; for example, when the first output load capacity T1 is less than the total load X required by the area with demand and less than or equal to T2, the air conditioning system A2 with the second output capacity is started to meet the demand of the area.

The second control scenario: the control unit can be specifically used for controlling the simultaneous opening of more than two air conditioning systems corresponding to the (n +1) th output load if the total load required by the area with the starting requirement is greater than the (n) th output load and less than or equal to the (n +1) th output load for the combined air conditioning system formed by combining more than two air conditioning systems from the first air conditioning system to the (n) th air conditioning system; and the (n +1) th output load is greater than the nth output load and less than or equal to the total output load.

For example: when the nth output load capacity Tn is smaller than the required area, the required total load X is smaller than or equal to the nth +1 output load capacity T (n +1), two or more air conditioning systems corresponding to the nth +1 output load capacity T (n +1) need to be started simultaneously to meet the requirement of the area. And repeating the steps until the total load X required by the region with the demand is equal to the maximum output load capacity Tmax, simultaneously starting all the units, and controlling the units to output according to the maximum allowable output load Tmax of the region.

Therefore, at least part of the air-conditioning systems in the multi-air-conditioning system are controlled to be started by aiming at the setting forms of the air-conditioning systems corresponding to different output capacities of the multi-air-conditioning system, the at least part of the air-conditioning systems can meet the total load required by the area with the starting requirement, different starting requirements can be met, and energy can be saved.

In an alternative embodiment, at least one additional control process of: such as a first additional control process, a second additional control process, etc.

The first additional control process: after controlling at least part of the air conditioning systems in the multi-air conditioning system to be turned on, wherein the at least part of the air conditioning systems can meet the total load required by the area with the starting requirement, the method further comprises the following steps: and (3) a process of maintaining the multi-air-conditioning system.

And the control unit can be further used for removing the failed air conditioning system from the multiple air conditioning systems if the air conditioning system in at least one turned-on air conditioning system fails after controlling at least part of the multiple air conditioning systems to be turned on and meeting the total load required by the area with the starting requirement.

And the control unit can be further used for controlling at least part of the air conditioning systems in the remaining air conditioning systems, which can meet the total load required by the area with the starting requirement, to be turned on according to the total load required by the area with the starting requirement and the theoretical output load of the multiple remaining air conditioning systems by using the remaining air conditioning systems after the failed air conditioning system is removed from the multiple air conditioning systems, so that the total load required by the area with the starting requirement is met by using at least part of the air conditioning systems in the remaining air conditioning systems.

Therefore, at least part of the air-conditioning systems in the multi-air-conditioning system are controlled to be started, and the multi-air-conditioning system is maintained after the at least part of the air-conditioning systems can meet the total load required by the area with the starting requirement, so that the operation reliability of the multi-air-conditioning system can be improved, and the comfort experience of a user can be improved.

The second additional control process: in addition to the allocation by using the output load to match with the multi-air conditioning system, the method can further comprise the following steps: and (3) carrying out balanced control on the running time of each air-conditioning system in the multi-air-conditioning system.

The control unit may be further configured to, after controlling at least some of the air-conditioning systems in the multi-air-conditioning system to be turned on and the at least some of the air-conditioning systems can meet a total load required by an area with a start-up requirement, allocate, by using an operation time of the started-up air-conditioning system, other air-conditioning systems in the multi-air-conditioning system except the started-up air-conditioning system, so as to implement balanced control of the operation times of all the air-conditioning systems in the multi-air-conditioning system.

For example: except for utilizing output collocation to allocate, the system can also monitor the service time of each set of air conditioning system, and realize the balance of the running time of each system through allocation, thereby avoiding long-time uninterrupted running of a certain unit.

Therefore, the operating time of each air conditioning system in the multi-air conditioning system is subjected to balance control by utilizing the output load to match the multi-air conditioning system for allocation, so that damage caused by overlong operating time of some air conditioning systems can be avoided, and the reliability and the safety of operation can be improved.

Through a large number of tests, the technical scheme of the invention is adopted, and the output sharing of a plurality of sets of air conditioning systems and the uniform allocation of each area are realized in the multi-area control, so that the intelligent control of all areas is realized, the optimized output of all areas can be realized, and the energy waste is avoided.

According to an embodiment of the present invention, there is also provided a multi air conditioning system corresponding to a control apparatus of the multi air conditioning system. The multi air conditioning system may include: the control device of the multi-air conditioning system is described above.

Some regional control systems are realized by adding air valve controllers and regional control multi-air-conditioning systems on the basis of one-to-one unit, and can realize independent control of a plurality of small regions by controlling the opening and closing of air valves through the regional control multi-air-conditioning systems.

Although a set of zone control system can control a plurality of zones, if the whole area of a zone exceeds the load capacity of the air conditioning system, the air conditioning system needs to be matched to operate, and each air conditioning system is responsible for independent control of a part of the zones. Thus, there are some problems inevitable, such as: when only a small number of regions in the regional boards in charge of different air conditioning systems have the starting-up requirements, the air conditioning systems must keep the starting-up output state, so that the resource waste is caused, and the total load of the whole machine required by the regions with the possible starting-up requirements can be supplied only by one set of machine set.

In an optional embodiment, at least in order to solve the problem that the regional control system can cause energy waste when in overload output, for example, in order to solve the problem that the energy of overload output is wasted in regional control in which a plurality of sets of air conditioning systems are operated in a matched manner, the invention provides a multi-system regional intelligent control scheme for the regional control system, and the intelligent control of all regions is realized by output sharing of the plurality of sets of air conditioning systems and unified allocation of each region in multi-region control; therefore, the optimized output of a plurality of sets of air conditioning systems in multi-region control can be realized, and energy waste is avoided.

In an alternative embodiment, a specific implementation process of the scheme of the present invention can be exemplarily described with reference to the examples shown in fig. 2 to 4.

FIG. 2 is a schematic diagram of an embodiment of a zone control system. The zone control system as shown in fig. 2 may include: the system comprises a first area system 11, a second area system 12 and a third area system 13, wherein the first area system 11, the second area system 12 and the third area system 13 are independently arranged in parallel. The first area system is provided with a first air valve 21, a second air valve 22, a third air valve 23 and a fourth air valve 24, the second area system is provided with a fifth air valve 25, a sixth air valve 26 and a seventh air valve 27, and the third area system is provided with an eighth air valve 28, a ninth air valve 29 and a thirteenth air valve 30.

Some regional control systems (such as the regional control system shown in fig. 2) can control multiple regions, but if the total area of the region exceeds the load capacity of the air conditioning system itself, then the multiple air conditioning systems need to be considered to work together. Each set of air conditioning system operates independently and is in charge of control and management of the designated area independently.

When only a small number of regions in the regional plates in charge of different air-conditioning systems have starting requirements, the air-conditioning systems must keep a starting output state, and the total load of the whole machine required by the regions with the possible starting requirements can be supplied by only one set of unit, so that energy waste is caused. In the zone control system shown in fig. 2, if there is a start-up demand only at the first damper 21 of the first zone system 11, all the dampers of the first zone system 11, the second zone system 12 and the third zone system 13 must be kept in the start-up output state, which results in waste of energy.

The invention relates to a scheme, in particular to a multi-zone intelligent control scheme based on multiple sets of air conditioning systems.

FIG. 3 is a schematic diagram of an embodiment of a zone control system with multiple air conditioning system outputs shared. In the multiple air conditioning systems shown in fig. 3, a first air conditioning system 31, a second air conditioning system 32, and a third air conditioning system 33 are provided. For the first air conditioning system 31, a first air damper 41, a second air damper 42, a third air damper 43, and a fourth air damper 44 are provided. For the second air conditioning system 32, a fifth air damper 45, a sixth air damper 46 and a seventh air damper 47 are provided. For the third air conditioning system 33, an eighth damper 48, a ninth damper 49 and a tenth damper 50 are provided.

The output ends of the first air conditioning system 31, the second air conditioning system 32 and the third air conditioning system 33 share and output in a shared air duct manner. The first air valve 41, the second air valve 42, the third air valve 43, the fourth air valve 44, the fifth air valve 45, the sixth air valve 46, the seventh air valve 47, the eighth air valve 48, the ninth air valve 49 and the tenth air valve 50 share a control end.

Fig. 4 is a flowchart illustrating an embodiment of a multi-zone intelligent control method of a multi-zone control system. As shown in fig. 4, the multi-zone intelligent control process of the multi-zone control system may include:

and step 1, carrying out output sharing on a plurality of sets of air conditioning systems in a way of sharing air channels. Specifically, when the air conditioner is installed in a project, a plurality of air conditioning systems can share the air duct. For example: in the example shown in fig. 3, the air ducts of the first air conditioning system 31, the second air conditioning system 32, and the third air conditioning system 33 may be shared.

Step 2, the temperature controllers and air valves of all the areas receive, compile and return to the mouth one area control multi-air-conditioning system management in a unified way, and the specific receiving and compiling process can comprise the following steps:

and step 21, when n sets of air conditioning systems are judged, widening the existing controllable maximum area number m of the area control multi-air conditioning system to be n m, wherein m and n are natural numbers.

For example: in some air conditioning systems, each set of regional control system can only control m air valves (namely regions) due to the limitation of hardware, all regions need to be uniformly coordinated and controlled in an air duct sharing mode in the scheme of the invention, n sets of air conditioning systems correspond to n sets of regional control systems, and the whole controllable region is naturally widened to n m.

And step 22, uniformly collecting and coding the temperature controllers and numbering the temperature controllers. Specifically, the management of the temperature controllers of each set of system is performed, and if the first air conditioning system 21 is connected with 2 zone temperature controllers, the numbers are defined as No. 1 and No. 2; if the second air conditioning system 22 is connected with 4 zone thermostats, the numbers are defined as 3, 4, 5, 6 on the basis of the first air conditioning system 21, and so on.

And 23, uniformly collecting and coding the air valves and numbering the air valves. Specifically, the blast gate refers to the pairing relation with the temperature controller, and the numbering management is carried out by referring to the mode.

And 3, calculating the maximum allowable output load Tmax according to the total area of the region. Specifically, when receiving and compiling, the total output load of the air conditioners required by all the regions is calculated according to the area size of each region, the maximum allowable output load Tmax of the whole set of region control system is determined, and overload output in subsequent control is avoided.

And 4, sequencing and numbering the air conditioning systems according to the sequence of the output load capacity T from small to small, and recording as A1-An. And sorting the output load capacity T of single-region and multi-region collocation from small to large, and recording as T1-Tmax.

Specifically, numbering is carried out on the air conditioning system according to the size of the output capacity from small to large: a1 and A2 … … An, the output load capacities are T1 and T2 … … Tn respectively; synchronously, the sum of the output load capacities obtained by combining a plurality of systems is calculated, and sorting processing is carried out from small to large and is marked as T (n +1) … … Tmax.

Optionally, the output capacity grading among multiple sets of air conditioning systems may be divided according to actual conditions, for example, to minimize the switching back and forth among the air conditioning systems.

Step 5, realizing the comprehensive management of the air conditioning system according to the requirements of each area, which specifically comprises the following steps:

step 51, when the unit has a power-on demand, counting the total load X required by the area with the demand.

For example: the statistics is executed according to the actual area of the region, the region control system needs to input the area according to the actual environment in advance in the installation and debugging stage, and the refrigerating or heating capacities required by different areas are different. The statistics is mainly that when some areas need to be started, the total areas of the areas are counted, and then matching is carried out according to the capacity requirements corresponding to the total areas and the unit output capacity, so that all the air conditioning systems are uniformly allocated.

And step 52, when the total load X required by the required area is less than or equal to the first output load capacity T1, starting the air conditioning system A1 corresponding to the first output capacity to meet the requirement of the area.

And step 53, when the first output load capacity T1 is smaller than the total load X required by the area with the demand and is smaller than or equal to T2, starting the air conditioning system A2 with the second output capacity to meet the demand of the area.

And step 54, when the total load X required by the area with the n-1 th output load capacity T (n-1) < the demand is less than or equal to the n-th output load capacity Tn, starting the air conditioning system An with the n-th output capacity to meet the demand of the area.

And step 55, when the nth output load capacity Tn is smaller than the required area, the required total load X is smaller than or equal to the nth +1 output load capacity T (n +1), two or more air conditioning systems corresponding to the nth +1 output load capacity T (n +1) are required to be started simultaneously to meet the requirement of the area.

And repeating the steps until the total load X required by the region with the demand is equal to the maximum output load capacity Tmax, simultaneously starting all the units, and controlling the units to output according to the maximum allowable output load Tmax of the region.

And 6, if the organic unit fails in the operation process, the output collocation of the air conditioning system can actively eliminate the abnormal unit, and uninterrupted output is realized by the collocation of other systems, so that the normal use of a user is ensured.

Therefore, through the output sharing of the air conditioning system and the allocation output of the air conditioning system according to the total regional requirements, the optimal management of system energy can be realized, and the energy waste caused by overload output is avoided.

In addition, except for using output collocation for allocation, the system can also monitor the service time of each set of air conditioning system, realize the balance of the running time of each system through allocation, and avoid long-time uninterrupted running of a certain unit.

For example: in the above embodiment, all air conditioning systems are uniformly allocated according to comparison between the demand and the capacity, if the load demand is within a certain range for a long time, some units may be started to operate for a long time, and some units do not operate all the time, and the long-term operating units may be prone to failure. When a plurality of air conditioning systems are uniformly allocated, the output allocation mainly avoids energy waste, and the use time balance avoids the problem of long-time overload operation of certain units possibly caused by the output allocation.

Since the processing and functions of the multi-air conditioning system of the present embodiment are basically corresponding to the embodiments, principles and examples of the apparatus shown in fig. 1, the description of the present embodiment is not detailed, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.

Through a large number of tests, the technical scheme of the invention is adopted, a plurality of air-conditioning systems are output and shared in a way of sharing air channels, and the temperature controllers and air valves in all areas are uniformly received, compiled and returned to one area to control the management of the multi-air-conditioning system, so that the intelligent control of all areas can be realized, and the energy waste is avoided.

According to an embodiment of the present invention, there is also provided a control method of a multi-air conditioning system corresponding to the multi-air conditioning system, as shown in fig. 5, which is a schematic flow chart of an embodiment of the method of the present invention. The control method of the multi-air-conditioning system is applied to the multi-zone load output control corresponding to the multi-air-conditioning system, and the control method of the multi-air-conditioning system in the multi-zone load output control can comprise the following steps: step S110 to step S140.

At step S110, the multiple air-conditioning systems are controlled to be set in a manner of sharing the same air duct, that is, the air ducts of the air-conditioning systems in the multiple air-conditioning systems are controlled to be set in a sharing manner. The multi-air-conditioning system may include more than two air-conditioning systems, and the air ducts of the more than two air-conditioning systems are arranged in a shared manner, that is, the more than two air-conditioning systems can share the ventilation air duct.

For example: and a plurality of air conditioning systems carry out output sharing in a way of sharing an air duct. Specifically, when the air conditioner is installed in a project, a plurality of air conditioning systems can share the air duct.

At step S120, the theoretical output load of the multi air conditioning system is determined.

Optionally, the specific process of determining the theoretical output load of the multi-air conditioning system in step S120 may be further described with reference to a flowchart of an embodiment of determining the theoretical output load of the multi-air conditioning system in the method of the present invention shown in fig. 6, and may include: step S210 to step S240.

Step S210, the temperature controllers and the air valves of all the zones corresponding to the multi-air-conditioning system are collected and managed uniformly, that is, the temperature controllers and the air valves of all the zones are collected and managed uniformly and are managed by controlling the multi-air-conditioning system in one zone.

Second compilation management scenario: and according to the arrangement sequence of each air-conditioning system in the multi-air-conditioning system, uniformly collecting, managing the temperature controllers of each air-conditioning system in the multi-air-conditioning system.

The third scenario for revenue management: and according to the arrangement sequence of each air-conditioning system in the multi-air-conditioning system and corresponding to the arrangement sequence of the temperature controllers of each air-conditioning system in the multi-air-conditioning system, uniformly collecting, arranging and managing the air valves of each air-conditioning system in the multi-air-conditioning system.

In step S220, the total output load of the multi-air conditioning system is determined.

More optionally, the determining the total output load of the multi-air conditioner system in step S220 may include: calculating the total output load required by all the areas corresponding to the multi-air-conditioning system according to the area size of each area corresponding to the multi-air-conditioning system; and determining the total output load required by all the areas corresponding to the air conditioning systems as the total output load of the multi-air conditioning system.

And step S230, determining the output load capacity of each air conditioning system in the multi-air conditioning system within the capacity range of the total output load of the multi-air conditioning system. The output capacity grading among the air conditioning systems can be divided according to actual conditions, for example, the back-and-forth switching among the air conditioning systems is reduced as much as possible.

More optionally, the determining the output load capacity of each air conditioning system in the multiple air conditioning systems in step S230 may include: the output load capacity of a single air conditioning system in the multi-air conditioning system is determined, and the output load capacity of a combined air conditioning system of more than two single air conditioning systems in the multi-air conditioning system is determined.

Specifically, the single air conditioner output load of a single air conditioner system in the multi-air conditioner system is determined, the combined air conditioner output load of each combined air conditioner system after combination between more than two air conditioner systems in the multi-air conditioner system is determined, and the area output load of each area after single area and multi-area collocation in an area controlled by the multi-air conditioner system is determined. That is, the single air conditioner output load capacities of the air conditioning systems in the multi-air conditioning system are arranged according to a set sequence, and the zone output load capacities of the zones after the single zone and the multiple zones are matched are arranged according to the set sequence. And arranging the combined air conditioner output load capacities of the combined air conditioner systems combined among more than two air conditioner systems in the multi-air conditioner system according to a set sequence.

In step S130, in the case that the multi-air conditioning system has the start-up requirement, the total load required by the area having the start-up requirement is determined. For example: and in the comprehensive management of the air conditioning system according to the requirements of each area, when the unit has a starting requirement, counting the total load X required by the area with the requirement.

In step S140, at least some air conditioning systems in the multi-air conditioning system are controlled to be turned on according to the total load required by the area with the start-up requirement and the theoretical output load of the multi-air conditioning system, where the at least some air conditioning systems can satisfy the total load required by the area with the start-up requirement, so as to use the total load required by the area with the start-up requirement satisfied by the at least some air conditioning systems in the multi-air conditioning system.

Optionally, in step S140, at least a part of the air conditioning systems in the multi-air conditioning system is controlled to be turned on according to the total load required by the area with the start-up demand and the theoretical output load of the multi-air conditioning system, and the specific process that the at least part of the air conditioning systems can meet the total load required by the area with the start-up demand may include any one of the following control situations.

The first control scenario: for a single air-conditioning system, namely for the first to nth air-conditioning systems, if the total load required by the area with the starting requirement is less than or equal to the nth output load, the nth air-conditioning system is controlled to be started. For example: and when the total load X required by the area with the n-1 th output load capacity T (n-1) < the demand is less than or equal to the n-th output load capacity Tn, starting the air conditioning system An with the n-th output capacity to meet the demand of the area.

The second control scenario: for a combined air-conditioning system, namely a combined air-conditioning system formed by combining more than two air-conditioning systems from the first to the nth air-conditioning systems, if the total load required by a region with a starting requirement is greater than the nth output load and less than or equal to the (n +1) th output load, controlling the more than two air-conditioning systems corresponding to the (n +1) th output load to be started simultaneously; and the (n +1) th output load is greater than the nth output load and less than or equal to the total output load.

And step S320, after the failed air conditioning system is removed from the multiple air conditioning systems, controlling at least part of the air conditioning systems in the remaining air conditioning systems, which can meet the total load required by the area with the start-up requirement, to be turned on according to the total load required by the area with the start-up requirement and the theoretical output load of the multiple remaining air conditioning systems by using the remaining air conditioning systems after the failed air conditioning system is removed from the multiple air conditioning systems, so as to utilize the total load required by the area with the start-up requirement, which is met by at least part of the air conditioning systems, in the remaining air conditioning systems.

After at least part of the air conditioning systems in the multi-air conditioning system are controlled to be started and can meet the total load required by the area with the starting requirement, the running time of the started air conditioning system is utilized to allocate other air conditioning systems except the started air conditioning system in the multi-air conditioning system, so that the balanced control of the running time of all the air conditioning systems in the multi-air conditioning system is realized.
