BRIEF DESCRIPTION OF THE DRAWINGS
[0023] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0025] Figure 2 A schematic diagram of a building air conditioning control system according to an embodiment of the present invention Figure 2 . DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0027] The inventor found that the current building air conditioning control system is to centrally control all air conditioning temperatures, that is, the cooling capacity of all air conditioning temperatures in summer is the same, and the heating capacity of all air conditioning in winter is the same. This unified control method often causes people in the high area of the building to feel hot, and people in the low area of the building to feel cold, especially in high-rise and super high-rise building applications. The reason is that the density of air decreases with increasing temperature, so the density of low-temperature air is large and the density of high-temperature air is small, which causes low-temperature air to fall and high-temperature air to rise, making the bottom of the high-rise building a storage area for low-temperature air, while the high-rise building becomes a storage area for high-temperature air. At the same time, there are also factors such as the area and time of sunshine on the high-rise building are longer than the area and time of sunshine on the bottom of the high-rise building. All of the above factors lead to the fact that under unified temperature control, the air conditioner located in the high area of the building is in a state of insufficient cooling capacity or heating capacity, while the air conditioner located in the low area of the building is in a state of excessive cooling capacity or heating capacity, which causes energy waste.
[0028] In view of this, the present invention proposes a building air conditioning control system, such as Figure 1 As shown, including:
[0029] An air-conditioning cluster for the upper area of the building, used for providing air-conditioning cooling / heating services for the upper area of the building, an air-conditioning cluster for the lower area of the building, and a first communication protocol gateway, an industrial switch, and a display control terminal connected in sequence; the air-conditioning cluster for the upper area of the building and the air-conditioning cluster for the lower area of the building are respectively connected to the first communication protocol gateway through the first communication protocol bus.
[0030] Among them, the high area and the low area of the building are relative concepts. When arranging the building air conditioning control system, it can be divided by floor, such as the 10th floor or below is the low area of the building, and the 10th floor or above is the high area of the building; it can also be divided by height, such as the 100th floor or below is the low area of the building, and the 100th floor or above is the high area of the building. Under the building air conditioning control concept of this application, the specific division method is not limited.
[0031] The present invention arranges the air conditioning clusters in the high area of the building and the air conditioning clusters in the low area of the building respectively according to the temperature conditions in the high area of the building and the low area of the building, wherein the air conditioning clusters in the high area of the building are used to provide air conditioning cold / (slash " / " means or) hot services for the high area of the building, and the air conditioning clusters in the low area of the building are used to provide air conditioning cold / hot services for the low area of the building. The air conditioning clusters in the high area of the building and the air conditioning clusters in the low area of the building are respectively connected to the first communication protocol gateway through the first communication protocol bus, and the first communication protocol gateway is then connected to the display control terminal through the industrial switch, so that the display control terminal can interact with the air conditioning clusters in the high area of the building and the air conditioning clusters in the low area of the building.
[0032] Among them, the first communication protocol gateway can adopt a specific communication protocol (such as Modbus, BACnet, KNX, etc.) to enable the air conditioning cluster in the high area of the building and the air conditioning cluster in the low area of the building to exchange and convert data with the display control terminal. The industrial switch is used for data exchange and forwarding to ensure real-time communication between various devices in the system (such as air conditioning clusters and display control terminals). The display control terminal can be a computer terminal and / or a mobile terminal. When the display control terminal is a mobile terminal, the mobile terminal needs to establish a connection with the industrial switch through a wireless communication gateway. The mobile terminal can be a smart phone, tablet computer and other devices.
[0033] like Figure 1 As shown, the air-conditioning cluster in the upper area of the building and the air-conditioning cluster in the lower area of the building both include: an air-conditioning unit connected to the first communication protocol bus and multiple temperature sensors; in the air-conditioning cluster in the upper area of the building, the multiple temperature sensors are respectively installed outdoors and indoors in the upper area of the building; in the air-conditioning cluster in the lower area of the building, the multiple temperature sensors are respectively installed outdoors and indoors in the lower area of the building.
[0034] The display control terminal controls the required cooling capacity or heating capacity of the air-conditioning units in the air-conditioning cluster in the high area of the building based on the temperature data collected by multiple temperature sensors in the high area of the building. That is, the display control terminal ultimately controls the required cooling capacity or heating capacity of the air-conditioning units in the air-conditioning cluster in the high area of the building based on the temperature data collected by the temperature sensors installed outdoors in the high area of the building and the temperature data collected by the temperature sensors installed indoors in the high area of the building.
[0035] The display control terminal controls the required cooling capacity or heating capacity of the air-conditioning units in the air-conditioning cluster in the lower area of the building based on the temperature data collected by multiple temperature sensors in the lower area of the building. That is, the display control terminal ultimately controls the required cooling capacity or heating capacity of the air-conditioning units in the air-conditioning cluster in the lower area of the building based on the temperature data collected by the temperature sensors installed outdoors in the lower area of the building and the temperature data collected by the temperature sensors installed indoors in the lower area of the building.
[0036] The embodiments of the present invention take into account the influence of floor height factors on the cooling or heating effect and energy-saving effect of air conditioning, and provide a method for controlling the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the high area of the building according to the indoor and outdoor temperatures of the high area of the building, and controlling the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the low area of the building according to the indoor and outdoor temperatures of the low area of the building. Ultimately, the effect of accurately controlling the temperature in the high and low areas of the building can be achieved, which can maximize the comfort of people on different floors using the air-conditioning, while also saving energy consumption, avoiding waste of resources, and meeting green energy-saving requirements.
[0037] The embodiment of the present invention uses the display control terminal to control the air-conditioning units in the air-conditioning cluster in the high area of the building, and uses the display control terminal to control the air-conditioning units in the air-conditioning cluster in the low area of the building. It not only realizes precise temperature control of the zones, but also reduces the wiring difficulty compared to the wiring method of the entire building, realizes remote device-based unified management of the air-conditioning units, and reduces the difficulty of air-conditioning management operations in the building.
[0038] As for the display control end controlling the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the high-rise area of the building based on the temperature data collected by multiple temperature sensors in the high-rise area of the building, in the specific implementation process, the display control end can control the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the high-rise area of the building based on the difference between the temperature data collected by the temperature sensor installed outdoors in the high-rise area of the building and the temperature data collected by the temperature sensor installed indoors in the high-rise area of the building.
[0039] As for the display control end controlling the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the lower zone of the building based on the temperature data collected by multiple temperature sensors in the lower zone of the building, in the specific implementation process, the display control end can control the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the lower zone of the building based on the difference between the temperature data collected by the temperature sensor installed outdoors in the lower zone of the building and the temperature data collected by the temperature sensor installed indoors in the lower zone of the building.
[0040] Whether it is the regulation of the air-conditioning units in the air-conditioning cluster in the high area of the building or the regulation of the air-conditioning units in the air-conditioning cluster in the low area of the building, the present invention uses the indoor and outdoor temperature difference to control the cooling capacity or heating capacity required by the air-conditioning unit. It can be precisely adjusted according to factors such as the external environment and indoor human flow (high human flow will increase the indoor temperature; low human flow will decrease the indoor temperature), thereby providing a comfortable air-conditioning environment.
[0041] It is worth noting that the air-conditioning units referred to in various embodiments of the present invention can be understood as central air-conditioning. On this basis, the display control terminal controls the required cooling capacity or heating capacity of the air-conditioning units in the air-conditioning cluster in the high area of the building based on the temperature data collected by multiple temperature sensors in the high area of the building, which can be understood as the basic cooling capacity or basic heating capacity required by the air-conditioning units in the air-conditioning cluster in the high area of the building. Similarly, the display control terminal controls the required cooling capacity or heating capacity of the air-conditioning units in the air-conditioning cluster in the low area of the building based on the temperature data collected by multiple temperature sensors in the low area of the building, which is the basic cooling capacity or basic heating capacity required by the air-conditioning units in the air-conditioning cluster in the low area of the building.
[0042] People controlling the room temperature in each room of the building through the air conditioning control panel does not conflict with the concept of the present invention. For example, in the prior art, the cooling capacity or heating capacity required by the air conditioning unit is uniformly controlled without distinguishing between the high and low areas of the building. In summer, the temperature is uniformly set to 26°C on the air conditioning panel. The actual perceived temperature in the high and low areas of the building is different, and it often takes a long time for the temperature in the high area of the building to cool down. Based on the present invention, this problem can be effectively overcome, because the basic cooling capacity or basic heating capacity required for the air conditioning units in the air conditioning cluster in the high area of the building is different from the basic cooling capacity or basic heating capacity required for the air conditioning units in the air conditioning cluster in the low area of the building. Specifically, the present invention regulates the basic cooling capacity or basic heating capacity of the building in the high zone and the low zone respectively. In the actual operation of the air-conditioning unit, the temperature controlled by the air-conditioning control panel of each room in the high zone and the low zone of the building is then performed on the basic cooling capacity or the basic heating capacity of the corresponding zone. Compared with the prior art, people can reach the desired target temperature more quickly by controlling the temperature through the air-conditioning control panel, and the temperature control result is closer to the ideal perceived temperature, and there will be no effect of different perceived temperatures in the high zone and the low zone under the same temperature setting.
[0043] Among them, in accordance with the idea of this application that the air conditioning of the building is controlled according to the different temperatures in the high and low zones of the building to maximize the comfort of air conditioning and energy saving, the display control terminal can control the relationship between the difference in temperature data and the cooling capacity or heating capacity based on different calculation logics. In an optional embodiment, the difference in temperature data is positively correlated with the cooling capacity or heating capacity required by the air-conditioning unit. Further optionally, the difference between the temperature data collected by the temperature sensor outdoors in the high zone of the building and the temperature data collected by the temperature sensor installed indoors in the high zone of the building is proportional to the cooling capacity required by the air-conditioning unit in the air-conditioning cluster in the high zone of the building; the difference between the temperature data collected by the temperature sensor outdoors in the low zone of the building and the temperature data collected by the temperature sensor installed indoors in the low zone of the building is proportional to the cooling capacity required by the air-conditioning unit in the air-conditioning cluster in the low zone of the building.
[0044] Taking the difference between the temperature data collected by the temperature sensor installed outdoors in the high-rise area of the building and the temperature data collected by the temperature sensor installed indoors in the high-rise area of the building as an example, the cooling capacity or heating capacity required by the air-conditioning units in the air-conditioning cluster in the high-rise area of the building is controlled. The calculation formula for the cooling capacity or heating capacity is:
[0045] Q = K*t*V*ρ*ΔT;
[0046] Where Q is the cooling or heating capacity (KW); K is a constant used for unit conversion; t is time (h); V is the air flow rate (m 3 / h), that is, the amount of air entering the air conditioning equipment; ρ is the air density (kg / m 3 );ΔT is the difference between the temperature data collected by the outdoor temperature sensor in the high area of the building and the temperature data collected by the indoor temperature sensor installed in the high area of the building. The difference between the indoor temperature and the outdoor temperature is taken when cooling, and the difference between the outdoor temperature and the indoor temperature is taken when heating.
[0047] In one embodiment of the present invention (not shown in the figure), the temperature sensor installed outdoors in the high area of the building includes a first temperature sensor installed at the low point outdoors in the high area of the building and a second temperature sensor installed at the high point outdoors in the high area of the building. In the building air conditioning control system provided in this embodiment, temperature sensors are respectively provided at the low point outdoors and the high point outdoors in the high area of the building, namely, the first temperature sensor and the second temperature sensor. Compared with only one temperature sensor being provided outdoors in the high area of the building, the fault tolerance rate of inaccurate control caused by failure of the temperature sensor can be reduced; and compared with the means of providing multiple temperature sensors outdoors in the high area of the building to avoid failure of any temperature sensor, this embodiment can improve the accuracy of outdoor temperature collection in the high area of the building. It is worth noting that the low point outdoors in the high area of the building and the high point outdoors in the high area of the building are relative. Generally, the top floor of the building is the high point outdoors in the high area of the building, and the lowest point of the area divided by the high area of the building is the lowest point outdoors in the high area of the building.
[0048] Further, when the difference between the temperature data collected by the first temperature sensor and the temperature data collected by the second temperature sensor exceeds the first preset temperature threshold, the display control end determines the average value of the temperature data collected by the first temperature sensor and the temperature data collected by the second temperature sensor as the temperature data collected by the temperature sensor installed outdoors in the high area of the building. When the difference between the temperature data collected by the first temperature sensor and the temperature data collected by the second temperature sensor does not exceed the first preset temperature threshold, the display control end may determine the temperature data collected by the first temperature sensor or the temperature data collected by the second temperature sensor as the temperature data collected by the temperature sensor installed outdoors in the high area of the building. Of course, in this case, the display control end may still determine the average value of the temperature data collected by the first temperature sensor and the temperature data collected by the second temperature sensor as the temperature data collected by the temperature sensor installed outdoors in the high area of the building, and the present invention does not limit this.
[0049] In one embodiment of the present invention, the temperature sensor installed outdoors in the low zone of the building also includes a third temperature sensor installed at the low point outdoors in the low zone of the building and a fourth temperature sensor installed at the high point outdoors in the low zone of the building. Similarly, in the building air conditioning control system provided in this embodiment, temperature sensors, namely the third temperature sensor and the fourth temperature sensor, are respectively provided at the low point outdoors and the high point outdoors in the low zone of the building. Compared with only one temperature sensor being provided outdoors in the low zone of the building, the fault tolerance rate of inaccurate control caused by failure of the temperature sensor can be reduced; and compared with the means of providing multiple temperature sensors outdoors in the low zone of the building to avoid failure of any temperature sensor, this embodiment can improve the accuracy of outdoor temperature collection in the low zone of the building. It is worth noting that the low point outdoors in the low zone of the building and the high point outdoors in the low zone of the building are relative. Generally, the first floor of the building (close to the ground) is the low point outdoors in the low zone of the building, and the highest point of the area divided by the low zone of the building is the highest point outdoors in the low zone of the building.
[0050] Further, when the difference between the temperature data collected by the third temperature sensor and the temperature data collected by the fourth temperature sensor exceeds the second preset temperature threshold, the display control end determines the average value of the temperature data collected by the third temperature sensor and the temperature data collected by the fourth temperature sensor as the temperature data collected by the temperature sensor installed outdoors in the low area of the building. When the difference between the temperature data collected by the third temperature sensor and the temperature data collected by the fourth temperature sensor does not exceed the second preset temperature threshold, the display control end may determine the temperature data collected by the third temperature sensor or the temperature data collected by the fourth temperature sensor as the temperature data collected by the temperature sensor installed outdoors in the low area of the building. Of course, in this case, the display control end may still determine the average value of the temperature data collected by the third temperature sensor and the temperature data collected by the fourth temperature sensor as the temperature data collected by the temperature sensor installed outdoors in the low area of the building, and the present invention does not limit this.
[0051] In the embodiment of the present invention, Figure 2 As shown, the air-conditioning unit connected to the first communication protocol bus includes a first unit and a second unit; the first unit includes a second communication protocol interface and a protocol converter, and the protocol converter is used to convert the second communication protocol interface into a first communication protocol interface so that the first unit is connected to the first communication protocol bus; the second unit includes a first communication protocol interface to connect to the first communication protocol bus. Among them, the first unit can be an old air-conditioning unit in a building, or it can be an air-conditioning unit from a different manufacturer and with a different compatible communication protocol from the second unit. The second unit can be understood as an air-conditioning unit that supports air-conditioning networking technology on the existing market. The first communication protocol can be an RS485 communication protocol, the second communication protocol can be a CAN bus protocol, and the protocol converter is a protocol converter that supports CAN to RS485. In this embodiment, by setting a protocol converter inside the first unit, the first unit and the second unit can communicate compatibly, realize unified networking management and control, and are particularly suitable for the intelligent transformation of existing building air-conditioning networking.
[0052] The first unit and the second unit can communicate in the following ways:
[0053] In one embodiment (not shown), in the air conditioning cluster in the high area of the building, one of the multiple first units serves as the first host in the high area of the building, and the remaining first units serve as slaves of the first host to transmit their internal parameters to the first host, and the first host is used to transmit its internal parameters and the internal parameters of its slaves to the display control end; one of the multiple second units serves as the second host in the high area of the building, and the remaining second units serve as slaves of the second host to transmit their internal parameters to the second host, and the second host is used to transmit its internal parameters and the internal parameters of its slaves to the display control end. For the air conditioning cluster in the high area of the building, this embodiment utilizes the characteristics of the consistent protocol of the first unit itself and the consistent protocol of the second unit itself, and selects one host from each of the multiple first units and the multiple second units to transmit and communicate data with the display control end, thereby reducing the difficulty of networking and wiring in the high area of the building.
[0054] Similarly, in the air-conditioning cluster in the lower zone of the building, one of the multiple first units serves as the first host in the lower zone of the building, and the remaining first units serve as slaves of the first host to transmit their internal parameters to the first host, and the first host is used to transmit its internal parameters and the internal parameters of its slaves to the display control end; one of the multiple second units serves as the second host in the lower zone of the building, and the remaining second units serve as slaves of the second host to transmit their internal parameters to the second host, and the second host is used to transmit its internal parameters and the internal parameters of its slaves to the display control end. For the air-conditioning cluster in the lower zone of the building, this implementation method utilizes the characteristics of the consistent protocol of the first unit itself and the consistent protocol of the second unit itself, and selects one host from each of the multiple first units and the multiple second units to transmit and communicate data with the display control end, thereby reducing the difficulty of networking and wiring in the lower zone of the building.
[0055] In the above embodiment, each slave is provided with the communication address of its corresponding host. For example, the communication address of the first host is provided in the slave of the first host, and the slave is used to transmit its internal parameters to the first host, and then the first host transmits the internal parameters to the display control end. For example, the communication address of the second host is provided in the slave of the second host, and the slave is used to transmit its internal parameters to the second host, and then the second host transmits the internal parameters to the display control end.
[0056] In another embodiment (not shown), in the air conditioning cluster in the high area of the building, one of the multiple second units serves as the host of the high area of the building, and the multiple first units and the remaining second units located in the high area of the building serve as slaves for transmitting their internal parameters to the host, and the host is used to transmit its internal parameters and the internal parameters of its slaves to the display control end. Similarly, in the air conditioning cluster in the low area of the building, one of the multiple second units serves as the host of the low area of the building, and the multiple first units and the remaining second units located in the low area of the building serve as slaves for transmitting their internal parameters to the host, and the host is used to transmit its internal parameters and the internal parameters of its slaves to the display control end.
[0057] In each of the above embodiments, the internal parameters may include inlet and outlet water temperature, fan status, voltage and current, power, compressor status, fault alarm information, etc. During the specific operation, by transmitting the internal parameters of each unit to the display control terminal, the building operation and maintenance personnel can monitor the working status of each unit, discover and repair faults in time.
[0058] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
