Description
Technical Field
The invention belongs to the technical field of air conditioning systems, and particularly relates to a control method capable of automatically adjusting an air conditioning operation mode and a base station air conditioner designed based on the control method.
Background
With the rapid development of the mobile communication industry in China, the network scale is continuously enlarged, and the energy consumption is also increased more and more. According to the statistics of the national development and improvement commission, the annual power consumption of three operators in the mobile communication industry of China exceeds 200 hundred million degrees, wherein the annual power consumption of an air conditioning system for a base station only reaches 70 hundred million kilowatts, and accounts for 46 percent of the total power consumption of the base station.
In recent years, the chinese iron tower company has integrated base stations of three operators. After the base station is shared, the number of main devices in the communication base station is increased, the heat productivity of the devices is increased continuously, and the power consumption of the air conditioning system of the base station is increased accordingly. In the conventional base station air conditioner, a fan in an indoor unit of the conventional base station air conditioner keeps a working mode of continuous operation after an air conditioning system is started to operate, and even if the indoor temperature is adjusted to the optimum temperature for base station equipment, the indoor fan can still operate continuously, so that unnecessary waste of energy is caused, and the energy consumption of the air conditioning system is difficult to control effectively.
Therefore, the energy saving problem of the base station air conditioner has become an important issue facing the base station construction.
Disclosure of Invention
The invention provides a brand-new air conditioner control method for solving the energy-saving problem of a base station air conditioner, which achieves the design purpose of energy conservation and consumption reduction by controlling an air conditioner system to automatically switch the operation mode of the air conditioner system according to the ambient temperature and timely controlling a compressor and an indoor fan in the air conditioner system to stop operating.
In order to solve the technical problems, the invention adopts the following technical scheme:
in one aspect, the present invention provides an air conditioner control method, including: connecting and communicating an indoor unit of the air conditioner with an external controller; the controller is provided with a refrigeration set temperature Tc and a heating set temperature Th; detecting the indoor environment temperature T; if T is larger than or equal to Tc, the controller generates a refrigeration instruction, transmits the refrigeration instruction to the air-conditioning indoor unit and controls the air-conditioning system to perform refrigeration operation; if Tc-Delta T is less than T and less than Tc, the controller generates an air supply instruction, transmits the air supply instruction to the indoor unit of the air conditioner and controls the air supply operation of the air conditioning system, wherein the Delta T is temperature difference, and Tc-Delta T is more than Th; if the Th is less than or equal to T and less than or equal to Tc-Delta T, the controller generates a shutdown instruction, transmits the shutdown instruction to the air-conditioning indoor unit and controls an air-conditioning system to be shut down; and if T is less than Th, the controller generates a heating instruction and transmits the heating instruction to the indoor unit of the air conditioner to control the heating operation of the air conditioning system.
In order to avoid the influence on the running stability of the air conditioning system caused by frequent switching between the two running modes of refrigeration and air supply when the indoor environment temperature T of the air conditioning system is reduced to be close to the set refrigeration temperature Tc, the controller can be provided with a return difference temperature delta T; when the controller controls the air conditioning system to perform refrigeration operation, the operation mode of the air conditioning system is switched to the air supply mode only when the indoor environment temperature T is detected to be reduced to be lower than Tc-Deltat.
Similarly, in order to avoid the problem that the air conditioning system is frequently started and stopped when the indoor environment temperature T rises to be close to the heating set temperature Th, the controller is arranged to control the air conditioning system to be stopped when the controller controls the air conditioning to operate in a heating mode and only when the indoor environment temperature T is detected to rise to be higher than Th plus delta T.
Preferably, the temperature difference Δ T can be set manually by the controller, and Δ T is preferably selected from 5 ℃ to 15 ℃; alternatively, the temperature difference Δ T may be automatically generated by the controller, and Δ T = | (Tc-Th)/2 |.
Further, when the controller is closed, a shutdown instruction is generated and transmitted to the air conditioner indoor unit, so as to control the air conditioner system to be shut down. That is, the air conditioning system may be shut down by turning off the controller.
On the other hand, the invention also provides a base station air conditioner based on the air conditioner control method, which comprises an indoor unit, an outdoor unit and a controller, wherein the controller is externally arranged on the indoor unit and is connected and communicated with the indoor unit; the controller receives the input refrigeration set temperature Tc and the heating set temperature Th, and switches the operation mode of the base station air conditioner according to the indoor environment temperature T: if T is larger than or equal to Tc, the controller generates a refrigeration instruction, transmits the refrigeration instruction to the indoor unit and controls the air conditioner of the base station to perform refrigeration operation; if Tc-Delta T < T < Tc, the controller generates an air supply instruction, transmits the air supply instruction to the indoor unit and controls the air supply operation of the base station air conditioner, wherein the Delta T is a temperature difference, and Tc-Delta T is more than Th; if the Th is less than or equal to T and less than or equal to Tc-Delta T, the controller generates a shutdown instruction, transmits the shutdown instruction to the indoor unit and controls the base station air-conditioning system to be shut down; and if T is less than Th, the controller generates a heating instruction and transmits the heating instruction to the indoor unit to control the base station air conditioner to perform heating operation.
Further, a temperature measuring device is further arranged in the base station air conditioner and used for detecting the indoor environment temperature T, and the temperature measuring device is arranged in the indoor unit or the controller.
Still further, the base station air conditioner uploads the operation parameters to the dynamic loop monitoring equipment in the base station through the controller, so as to meet the remote monitoring requirement on the electronic equipment in the base station.
Further, under the condition that the base station air conditioner is connected with the controller, if the controller is controlled to be closed, the controller generates a shutdown instruction to be transmitted to the indoor unit, and the base station air conditioner is controlled to be shut down; and under the condition that the base station air conditioner is disconnected from the controller, the indoor unit controls the operation mode of the base station air conditioner.
Compared with the prior art, the invention has the advantages and positive effects that: the invention adopts the independent controller to automatically switch the operation mode of the air-conditioning system, when the control strategy of the air-conditioning system needs to be adjusted, the system upgrading operation is not needed to be carried out on the air-conditioning host machine one by one, and the whole air-conditioning system can be controlled to automatically operate according to the adjusted control strategy only by adjusting the software program in the controller, thereby greatly simplifying the upgrading and debugging operation of the air-conditioning system. In addition, the air conditioner control method breaks through the working mode that the indoor fan of the air conditioner system in the conventional industry continuously operates after the air conditioner system is started to operate, so that the operating mode of the base station air conditioner can be automatically switched according to the ambient temperature in the base station in the automatic operation process, and the indoor fan is automatically controlled to stop operating when the ambient temperature in the base station meets the working requirement of the electronic equipment in the base station, so that the temperature condition required by the stable and reliable operation of the electronic equipment in the base station can be ensured, the operating power consumption of the base station air conditioner can be effectively reduced, and the technical effects of energy conservation and consumption reduction are achieved.
Other features and advantages of the present invention will become more apparent from the detailed description of the embodiments of the present invention when taken in conjunction with the accompanying drawings.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
In order to improve the energy-saving effect of the air conditioning system, especially for base station air conditioners which work in a communication machine room provided with a large number of main devices, the operation mode of the air conditioning system is automatically switched, and when the indoor environment temperature reaches the working temperature suitable for indoor electronic devices, the compressor and the indoor fan in the air conditioning system are automatically controlled to stop operating, so that the energy waste is avoided, and the technical effects of energy conservation and consumption reduction are achieved.
In order to control the base station air conditioner to automatically switch the operation mode of the base station air conditioner according to the indoor environment temperature, the embodiment adopts an independent controller, the external controller is externally connected to the indoor unit of the air conditioner, and the external controller is used as an upper computer of the existing base station air conditioner, so that the automatic control of the operation mode of the base station air conditioner is realized.
On one hand, the external controller is not required to be changed on the basis of the existing base station air conditioner, and only by connecting the controller with the existing communication interface configured on the indoor unit of the base station air conditioner, the base station air conditioner can adjust the self operation mode according to the received control instruction and execute a brand new control strategy. For the base station which is put into use, the energy-saving purpose of reducing the energy consumption of the base station can be achieved without changing the construction of the existing base station. On the other hand, for the base station provided with a plurality of air conditioners, one controller can simultaneously control a plurality of base station air conditioners to synchronously operate, and system upgrading operation is not required to be carried out on each base station air conditioner one by one, so that the system upgrading and maintaining process can be greatly simplified, and the working efficiency is improved.
For most base station air conditioners at present, a communication interface, such as an RS485 interface, for connecting a moving loop monitoring device is provided. The dynamic ring monitoring equipment, namely, the dynamic environment monitoring equipment, refers to equipment for centralized monitoring of power equipment and environment variables in various machine rooms. In order to facilitate the connection and communication between the controller and the indoor unit of the base station air conditioner, in this embodiment, it is preferable that an existing RS485 interface on the indoor unit of the air conditioner is connected to the controller, that is, the controller is connected to the RS485 interface of the indoor unit of the base station air conditioner through an RS485 bus, as shown in fig. 1, a control instruction is sent to the indoor unit through the controller, so as to adjust the operation mode of the base station air conditioner.
The controller can be further provided with a RS485 interface for connecting the moving ring monitoring equipment, and the communication protocol is unchanged, so that the operating parameters of the base station air conditioner can be uploaded to the moving ring monitoring equipment through the controller to meet the requirement of remote monitoring.
As shown in fig. 2, a worker can turn on or off the controller or adjust an operation mode (e.g., cooling, heating, blowing, automatic, dehumidifying), a wind speed (e.g., low wind, medium wind, high wind), a wind direction, an operation state (e.g., operation, maintenance, malfunction), and the like of the air conditioning system by operating the human-machine interface.
When an indoor unit of the base station air conditioner is externally connected with a controller, the controller is adopted to control the base station air conditioner to operate, the controller is kept in a power-on state, and if the controller receives a power-off instruction, the controller sends the power-off instruction to the base station air conditioner connected with the controller before the controller is powered off, so that the base station air conditioner connected with the controller is controlled to be powered off together.
If the air conditioning system is not controlled by the controller, the connection between the indoor unit of the base station air conditioner and the controller is disconnected, and the working state of the base station air conditioner is directly controlled through the man-machine interface on the base station air conditioner.
The air conditioner control method according to the present embodiment will be specifically described below with reference to fig. 3 to 6.
In order to solve the energy-saving problem of the base station air conditioner, an automatic mode is added in the operation mode of the base station air conditioner, that is, the controller automatically adjusts the operation mode of the base station air conditioner according to the indoor environment temperature, such as a cooling mode, a heating mode, an air supply mode and the like, and automatically controls a compressor in an outdoor unit of the air conditioner and an indoor fan in an indoor unit to stop operating when the indoor environment temperature is at the suitable environment temperature corresponding to the electronic equipment in the base station, so that the problem of energy waste caused by the uninterrupted operation of the indoor fan after the air conditioner is started to operate in the conventional air conditioner product is solved, and the overall power consumption of the air conditioner system in the base station is reduced to a certain extent.
As shown in fig. 3, the air conditioner control method of the present embodiment mainly includes the following steps:
s301, starting up an air conditioner of the base station, and electrifying and initializing;
and operating a power-on and power-off key on the controller, controlling the base station air conditioner connected with the controller to be started up while controlling the controller to be started up, and finishing the initialization configuration of each parameter.
S302, selecting to enter an automatic mode, and controlling the air conditioner of the base station to automatically run;
and selecting an automatic mode on a human-computer interface of the controller, and controlling the base station air conditioner to work in the automatic mode, namely enabling the base station air conditioner to adaptively switch the running mode of the base station air conditioner according to the ambient temperature in the base station.
S303, setting a refrigeration set temperature Tc and a heating set temperature Th;
according to the specific requirements of electronic equipment in the base station on the temperature of the working environment, the refrigeration set temperature Tc and the heating set temperature Th are determined and input to the controller through a human-computer interface on the controller. The cooling set temperature Tc is a critical temperature for starting the cooling mode, and the heating set temperature Th is a critical temperature for starting the heating mode.
S304, detecting the indoor environment temperature T;
in this embodiment, the existing temperature measuring device in the base station air conditioner indoor unit can be used to detect the indoor environment temperature and transmit the indoor environment temperature to the controller; or, a temperature measuring device can be directly arranged on the controller, so that the controller has the indoor environment temperature detection function.
S305, if T is larger than or equal to Tc, controlling the base station air conditioner to automatically run in a refrigeration mode;
when the controller detects that the indoor environment temperature T is greater than or equal to the set refrigeration temperature Tc (the set refrigeration temperature Tc can be between 15 ℃ and 40 ℃, preferably Tc =30 ℃), it indicates that the indoor environment temperature is too high, and the base station air conditioner needs to perform refrigeration operation to quickly reduce the environment temperature in the base station. At the moment, the controller generates a refrigeration instruction, transmits the refrigeration instruction to an indoor unit of the base station air conditioner, starts an indoor fan and an outdoor compressor of the base station air conditioner to operate, and controls the base station air conditioner to work in a refrigeration operation mode.
In the process of refrigerating operation of the base station air conditioner, the indoor fan and the outdoor compressor are always kept in an operating state. During this period, when the controller detects that the indoor ambient temperature T has dropped below Tc- Δ T, that is, T < Tc- Δ T, which is the return difference temperature, the return difference temperature may be a fixed value previously written in the program, for example, Δ T =2 ℃ or Δ T =3 ℃, or the controller may be written by the operator in step S303 in accordance with actual demand. At this time, the controller generates an air supply instruction, transmits the air supply instruction to the indoor unit of the base station air conditioner, and controls the base station air conditioner to switch the operation mode from the refrigeration operation to the air supply operation so as to turn off the outdoor compressor and only keep the indoor fan continuously operating, thereby reducing the energy consumption of the system, which is shown in fig. 4. Then, the process returns to step S304.
S306, if Tc-Delta T is less than T and is less than Tc, controlling the base station air conditioner to automatically run in an air supply mode, and returning to the step S304;
when the controller detects that the indoor environment temperature T is between Tc-Delta T and Tc (the Delta T is temperature difference and meets the value requirement of Tc-Delta T & gt Th), the indoor environment temperature is moderate, the controller generates an air supply instruction, the air supply instruction is transmitted to an indoor unit of the base station air conditioner, and the air supply operation of the base station air conditioner is controlled. At the moment, the indoor fan of the base station air conditioner is in an operating state, and the outdoor compressor is in a closing state, so that the energy consumption is reduced.
In this embodiment, the temperature difference Δ T may be set manually, for example, in step S303, the operator writes the temperature difference Δ T into the controller according to actual requirements, and the temperature difference Δ T is preferably set between 5 ℃ and 15 ℃, and in this embodiment, Δ T =10 ℃. Of course, the temperature difference Δ T may be automatically generated by the controller, and for example, the temperature difference Δ T may be calculated by using the formula Δ T = | (Tc-Th)/2 |. Here, the symbol "|" indicates taking an integer.
In the process of air supply operation of the base station air conditioner, the indoor fan is always kept in an operation state, and the outdoor compressor is always kept in a closed state. During the period, when the controller detects that the indoor environment temperature T is reduced to Tc-Delta T, a stop command is generated and transmitted to an indoor unit of the base station air conditioner, and the base station air conditioner is controlled to switch the operation mode from the air supply operation to the stop mode so as to control the indoor fan to stop operating. At this time, the outdoor compressor and the indoor fan in the air conditioning system are both in a closed state, so that energy waste can be avoided, and the technical effect of further energy saving is achieved, as shown in fig. 4.
S307, if Th is less than or equal to T and less than or equal to Tc-Delta T, controlling an outdoor compressor and an indoor fan of the base station air conditioner to stop running, and returning to the step S304;
when the controller detects that the indoor environment temperature T is between Th and Tc-DeltaT, the indoor environment temperature is a very suitable environment temperature for the electronic equipment in the base station, and no adjustment is needed. At the moment, the controller generates a stop instruction, transmits the stop instruction to the indoor unit of the base station air conditioner, and controls the base station air conditioner to stop, so that the indoor fan and the outdoor compressor of the base station air conditioner are both in a closed state, and the energy waste is avoided.
During the shutdown of the base station air conditioner, if the controller detects that the indoor ambient temperature T drops below Th, that is, T < Th, a heating instruction is generated and transmitted to the indoor unit of the base station air conditioner to start the operation of the indoor fan and the outdoor compressor of the base station air conditioner, and the base station air conditioner is controlled to switch to a heating operation mode to quickly raise the ambient temperature in the base station, as shown in fig. 4.
S308, if T is less than Th, controlling the base station air conditioner to automatically run in a heating mode;
when the controller detects that the indoor ambient temperature T is lower than the heating set temperature Th (the heating set temperature Th may be set to be between 0 ℃ and 20 ℃, preferably, Th =5 ℃), it indicates that the indoor ambient temperature is too low, and the air conditioner of the base station performs heating operation to quickly raise the ambient temperature inside the base station. At the moment, the controller generates a heating instruction, transmits the heating instruction to an indoor unit of the base station air conditioner, starts an indoor fan and an outdoor compressor of the base station air conditioner to operate, and controls the base station air conditioner to operate in a heating mode.
In the process of heating operation of the base station air conditioner, the indoor fan and the outdoor compressor are always kept in an operating state. During this period, if the controller detects that the indoor ambient temperature T rises above Th +. DELTA.t, i.e., T > Th +. DELTA.t, the controller generates a shutdown command, transmits the command to the indoor unit of the base station air conditioner, controls the base station air conditioner to switch the operation mode from heating operation to shutdown, and shuts down the outdoor compressor and the indoor fan to save energy, as shown in fig. 4. Then, the process returns to step S304.
And in the process of controlling the operation of the base station air conditioner by the controller, setting the controller to send a control instruction to the base station air conditioner once every 3 seconds. If the staff in the base station executes the shutdown operation, the controller firstly generates a shutdown instruction, transmits the shutdown instruction to the indoor unit of the base station air conditioner, controls the base station air conditioner to shut down, and then controls the base station air conditioner to enter a shutdown state.
The embodiment introduces the return difference temperature Δ t into the air conditioner control method, so that the base station air conditioner can be effectively prevented from being frequently switched between two operation modes, for example, the frequent switching between the cooling operation and the air supply operation, or the frequent switching between the heating operation and the shutdown. Therefore, the stability of the operation of the base station air conditioner can be improved, and the outdoor compressor and the indoor fan can be prevented from being frequently started, so that the design purposes of energy conservation and consumption reduction are further achieved.
FIG. 5 shows the working intervals of the outdoor compressor and the indoor fan of the base station air conditioner when the ambient temperature in the base station changes between 20 ℃ and 40 ℃ within 24 hours of a certain day in summer. Wherein the refrigeration set temperature Tc =30 ℃ and the temperature difference DeltaT =10 ℃. As can be seen from fig. 5, the outdoor compressor and the indoor fan of the air conditioning system are both in working states between 5 o 'clock and 16 o' clock in summer, which results in large power consumption; and between 16 o 'clock and 5 o' clock of the next day, only the indoor fan is operated, and the outdoor compressor is stopped, so that the power consumption is relatively small.
Fig. 6 shows the working intervals of the outdoor compressor and the indoor fan of the air conditioner of a base station when the ambient temperature in the base station changes between 0 ℃ and 20 ℃ within 24 hours of a certain day in winter. The set heating temperature Th =5 ℃, the set cooling temperature Tc =30 ℃, and the temperature difference Δ T =10 ℃. As can be seen from fig. 6, the base station air conditioner is in a shutdown state between 6 o 'clock and 20 o' clock in winter, and basically has no power consumption; and between 20 o 'clock and 6 o' clock of the next day, outdoor compressor and indoor fan are all in operating condition, and the power consumption is big.
The air conditioner control technology of this embodiment can control the automatic self-adaptation of base station air conditioner according to the change of in-station ambient temperature and adjust its operational mode, when effectively reducing the system consumption, can show the intelligent level that promotes the base station air conditioner.
Of course, the air conditioning control technology of the present embodiment may also be applied to other air conditioning products besides the base station air conditioner, and the present embodiment does not specifically limit this.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
