[0046] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present application.

[0047] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can also include other order instances in addition to those illustrated or described. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0048] In the related art, with the increase of servers and communication devices in the machine room, air conditioners have become indispensable equipment in the machine room. The existing machine room refrigeration scheme generally adopts a decentralized air-cooled unit type air conditioning system (the decentralized air-cooled unit type air conditioning system is an air-cooled air conditioning module independent of each other, can adopt N+X redundancy configuration, and the refrigeration system is arranged more flexibly, has high safety, and is convenient for staged expansion construction). However, with the iterative development of network technology, the equipment in the machine room is increasing, in order to meet the refrigeration demand, the air conditioner deployed in the machine room needs to be operated at high power all the time, the power consumption of a single cabinet is continuously rising, for example, in summer, due to the hot and high temperature of the outdoor environment, heat is accumulated or cannot be discharged in time, causing the air conditioner outdoor unit high pressure alarm and causing failure, endangering the safe operation of the IT equipment in the communication machine room building, increasing the energy consumption, increasing the failure rate of the air conditioner, and reducing the safety of the communication equipment in the machine room.

[0049] Based on the above technical problem, the present application sets multiple working modes for the air conditioner in the machine room, and when the second running mode is started, the target compressor with the smallest capacity in the air conditioner is started. According to the temperature in the machine room, the working mode can be automatically switched to the matching working mode, avoiding the air conditioner in the machine room being always in a high-power running state, and only starting the target compressor with the smallest capacity when only one compressor is started, thereby reducing the energy consumption, avoiding frequent switching of the compressor, and reducing the failure rate of the air conditioner.

[0050] Figure 1A structure schematic diagram of an air conditioner provided by an embodiment of the present application is shown in Figure 1 The air conditioner can include an air conditioner body arranged in a machine room, and a controller and multiple compressors in the air conditioner. In addition, a temperature sensor is arranged in the machine room to obtain a first temperature value in the machine room. The controller is configured to obtain the first temperature value collected by the temperature sensor, and if the first temperature value is higher than a first preset temperature, a first operation mode is started, wherein the first operation mode is that the multiple compressors in the air conditioner are all in an open state, and if the first temperature value is lower than the first preset temperature and higher than a second preset temperature, it is determined whether the capacities of the multiple compressors in the air conditioner are the same, and if the capacities of the multiple compressors in the air conditioner are different, a target compressor with the smallest capacity in the air conditioner is started when a second operation mode is started. In addition, the first preset temperature is higher than the second preset temperature, and the values of the first preset temperature and the second preset temperature can be set according to actual application scenarios, which will not be discussed in detail here.

[0051] In addition, a multiple-fan assembly can be arranged in the air conditioner, and a temperature sensor can also be arranged outside the machine room to obtain a second temperature value outside the machine room. The controller can also be configured to obtain the second temperature value collected by the temperature sensor, and determine a first temperature difference between the first temperature value and the second temperature value, and if the first temperature difference is lower than a preset temperature difference threshold, the multiple-fan assembly is started.

[0052] In addition, after the multiple-fan assembly is started, the controller can also be configured to:

[0053] re-obtain a third temperature value collected by the temperature sensor, wherein the third temperature value is a temperature value in the machine room after the multiple-fan assembly is started for a preset time length, determine a second temperature difference between the third temperature value and the second temperature value, and if the second temperature difference is lower than a temperature difference threshold, switch to a warning mode.

[0054] In addition, the air conditioner can also include a condenser, and the controller can also be configured to:

[0055] determine a preset pressure range and a maximum working current corresponding to a current operation mode, wherein the current operation mode is the first operation mode or the second operation mode, obtain a condensing pressure of the condenser, current values of the compressors and the multiple-fan assembly in the current operation mode, and if the condensing pressure of the condenser is not within the preset pressure range and / or the current values of the compressors and the multiple-fan assembly are higher than the maximum working current, switch to the warning mode.

[0056] The technical solutions of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0057] Figure 2The flowchart of the air conditioner control method provided in the embodiment of the present application can be executed by a controller of an air conditioner. The air conditioner is deployed in a machine room and includes multiple compressors. As shown in Figure 2 The method of the embodiment can include the following steps.

[0058] S201: Obtain a first temperature value collected by a temperature sensor, where the first temperature value is a temperature value in the machine room.

[0059] In the embodiment, a temperature sensor can be deployed in the machine room to collect a first temperature value in the machine room. In addition, the specific setting position of the temperature sensor in the machine room can be set according to the actual application scenario.

[0060] S202: If the first temperature value is higher than a first preset temperature, start a first operation mode, where the first operation mode is that the multiple compressors in the air conditioner are all in an open state.

[0061] In the embodiment, after obtaining the first temperature value, the working mode of the air conditioner can be determined according to the relationship between the obtained first temperature value and the first preset temperature.

[0062] Optionally, if the obtained first temperature value is higher than the first preset temperature, the first operation mode can be started. The first operation mode is that the multiple compressors in the air conditioner are all in an open state.

[0063] S203: If the first temperature value is lower than the first preset temperature and higher than a second preset temperature, determine whether the capacities of the multiple compressors in the air conditioner are the same.

[0064] In the embodiment, if the first temperature value is lower than the first preset temperature and higher than the second preset temperature, the second operation mode can be started. The second operation mode is that a target compressor in the air conditioner is in an open state. In addition, the second preset temperature is lower than the first preset temperature.

[0065] S204: If the capacities of the multiple compressors in the air conditioner are different, start a target compressor with the smallest capacity in the air conditioner when the second operation mode is started.

[0066] In addition, the method can further include the following steps.

[0067] If the capacities of the multiple compressors in the air conditioner are the same, start any target compressor in the air conditioner when the second operation mode is started, and the target compressor is a variable frequency compressor.

[0068] In the embodiment, when the second operation mode is started, it can be determined whether the capacities of the plurality of compressors in the air conditioner are same. If the capacities of the plurality of compressors in the air conditioner are different, when the second operation mode is started, the target compressor with the smallest capacity in the air conditioner is started.

[0069] In addition, when the second operation mode is started, different compressors can be started according to the capacities of the compressors. Alternatively, if the capacities of the plurality of compressors in the air conditioner are same, when the second operation mode is started, any target compressor in the air conditioner is started. If the capacities of the plurality of compressors in the air conditioner are different, when the second operation mode is started, the target compressor with the smallest capacity in the air conditioner can be started.

[0070] Further, Figure 3 The principle schematic diagram of the air conditioner control method provided in the embodiment is shown in FIG. 1. In the embodiment, two compressors can be arranged in the air conditioner, which are compressor 1 and compressor 2, and the capacity of the compressor 1 is smaller than that of the compressor 2. A temperature sensor can collect a first temperature value in a machine room, and then the first temperature value can be sent to a controller. The controller can start different operation modes according to the relationship between the first temperature value and a first preset temperature. Alternatively, if the first temperature value is higher than the first preset temperature, the first operation mode can be started. If the first temperature value is lower than the first preset temperature and higher than a second preset temperature, the second operation mode can be started. If the first temperature value is lower than the second preset temperature, the third operation mode can be started. Figure 3

[0071] In summary, when two compressors with different capacities are arranged, the small-capacity compressor is preferentially started under normal circumstances, which can effectively avoid frequent switching between the compressors, and thus the use time of the compressors is prolonged.

[0072] Alternatively, when the first operation mode and the second operation mode are switched, the corresponding pipe opening and closing electromagnetic valve group can be used to achieve the switching. For example, if the compressor 1 corresponds to the evaporator 1 and the electromagnetic valve group 1, and the compressor 2 corresponds to the evaporator 2 and the electromagnetic valve group 2, the electromagnetic valve group can be used to achieve the opening and closing of the pipes at both ends of the compressor and the evaporator.

[0073] In addition, if the first temperature value is lower than the second preset temperature, the air conditioner can be turned off.

[0074] ​After the above scheme, the first temperature value collected by the temperature sensor in the machine room can be obtained. If the first temperature value is higher than the first preset temperature, the first operation mode in which all the compressors in the air conditioner are in the open state is started. If the first temperature value is lower than the first preset temperature and higher than the second preset temperature, it is determined whether the capacities of the plurality of compressors in the air conditioner are the same. If the capacities of the plurality of compressors in the air conditioner are different, the target compressor with the smallest capacity in the air conditioner is started when the second operation mode is started. By pre-setting multiple operation modes for the air conditioner in the machine room, and starting the target compressor with the smallest capacity in the air conditioner when the second operation mode is started, the air conditioner in the machine room can be automatically switched to the matching operation mode according to the temperature in the machine room, avoiding the air conditioner in the machine room being always in a high-power consumption operation state. When only one compressor is started, only the target compressor with the smallest capacity is started, which reduces the energy consumption and avoids frequent switching of compressors, thereby reducing the failure rate of the air conditioner.

[0075] Based on Figure 2 the method, the present specification embodiment further provides some specific embodiments of the method, which are described below.

[0076] In another embodiment, the air conditioner is provided with a multi-fan assembly, and the method can further include:

[0077] Obtaining a second temperature value collected by a temperature sensor, wherein the second temperature value is a temperature value outside the machine room.

[0078] Determining a first temperature difference between the first temperature value and the second temperature value.

[0079] If the first temperature difference is lower than a preset temperature difference threshold, the multi-fan assembly is started.

[0080] In the present embodiment, the air conditioner is provided with a multi-fan assembly, and a temperature sensor can also be provided outside the machine room. The second temperature value outside the machine room can be obtained by the temperature sensor provided outside the machine room, and then the first temperature difference between the first temperature value and the second temperature value can be determined. If the first temperature difference is lower than a preset temperature difference threshold, the multi-fan assembly can be started. The temperature difference threshold can be set according to the actual application scenario, and for example, can be any value between 3-5 degrees. In addition, the multi-fan assembly can be an existing component, and for example, can be a combination of multiple fans.

[0081] In summary, the multi-fan assembly can ensure the sufficiency and uniformity of the heat dissipation of the condenser, and avoid the local overheating of the condenser due to the airflow dead angle.

[0082] In addition, after the multi-fan assembly is started, the method can further include:

[0083] acquire a third temperature value collected by the temperature sensor, wherein the third temperature value is a temperature value in the machine room after the multi-fan assembly is turned on for a preset time length.

[0084] determine a second temperature difference between the third temperature value and the second temperature value.

[0085] if the second temperature difference is lower than the temperature difference threshold, switch to a pre-warning mode.

[0086] Specifically, after the multi-fan assembly is turned on for a preset time length, a third temperature value can be acquired by a temperature sensor arranged in the machine room, and then a second temperature difference between the third temperature value and the second temperature value can be determined, and if the second temperature difference is lower than the temperature difference threshold, the pre-warning mode can be switched to. The preset time length can be set according to actual application scenarios.

[0087] Further, the air conditioner comprises a condenser, and the switching to the pre-warning mode can specifically include:

[0088] determining a preset pressure range and a maximum working current corresponding to a current operation mode, wherein the current operation mode is the first operation mode or the second operation mode.

[0089] acquiring a condensing pressure of the condenser, a current value of the compressor and the multi-fan assembly in the current operation mode.

[0090] if the condensing pressure of the condenser is not in the preset pressure range and / or the current value of the compressor and the multi-fan assembly is higher than the maximum working current, switching to the pre-warning mode.

[0091] Specifically, when switching to the pre-warning mode, the preset pressure range and the maximum working current corresponding to different operation modes can be different, and therefore, the preset pressure range and the maximum working current corresponding to the current operation mode can be determined first, and then whether to switch to the pre-warning mode can be determined according to the preset pressure range and the maximum working current corresponding to the current operation mode. Optionally, a pressure monitor can be used to monitor the pressure of the condenser and the suction and discharge pressures of the compressor, and a current monitor can be used to monitor the current value input by the fan and the compressor motor. In addition, the compressor is configured with a low-pressure and high-pressure protection mechanism, and the low-pressure and high-pressure protection set values of the compressor are generally wider than the condensing pressure, and therefore, the condensing pressure can be monitored and controlled in linkage with the system. The system sets multiple working modes, and determines and energy-saving adjusts through an intelligent control module, and the system is embedded with a safety protection algorithm and an operation mechanism (invention point), which is of great significance to improve the energy efficiency and safe operation of the system.

[0092] Exemplarily, Figure 4This is a schematic diagram illustrating the application of an air conditioning control method provided in another embodiment of this application, such as... Figure 4 As shown, in this embodiment, the current operating mode is the second operating mode. A first temperature value and a second temperature value can be collected by a temperature sensor. Then, it can be determined whether the temperature difference between the first and second temperature values ​​is less than a temperature difference threshold, which, for example, is 3 degrees Celsius. If it is less, an early warning mechanism can be activated, and the intelligent control module (in the controller) can adjust multiple fan groups. If the early warning cannot be eliminated, the condensing pressure and maximum operating current (operating current of the external fan and compressor) can be used to determine whether to switch to the early warning mode. If the condensing pressure of the condenser is not within the preset pressure range, or if the current value of the compressor and multiple fan components is higher than the maximum operating current, then the early warning mode is switched to.

[0093] In summary, by setting multiple working modes and using the intelligent control module for judgment and energy-saving adjustment, while also incorporating safety protection algorithms and operating mechanisms, the system's energy efficiency and safety are improved.

[0094] Furthermore, in another embodiment, after switching to the warning mode, the method may further include:

[0095] Generate early warning information.

[0096] The warning message is sent to the remote monitoring terminal.

[0097] In this embodiment, after switching to the early warning mode, an early warning message can be generated and then sent to the remote monitoring and control system to remind maintenance personnel to check for anomalies in a timely manner, thereby ensuring the security of the system.

[0098] In another embodiment, after sending the warning message to the remote monitoring terminal, the method may further include:

[0099] The system receives a control request sent by the remote monitoring terminal, wherein the control request contains parameters to be controlled.

[0100] Based on the control request, the device in the air conditioner corresponding to the parameter to be controlled is controlled.

[0101] In this embodiment, after sending the warning message to the remote monitoring terminal, a control request containing the parameter to be controlled can be received from the remote monitoring terminal. Then, the equipment in the air conditioner corresponding to the parameter to be controlled (e.g., compressor, multi-fan assembly, etc.) can be controlled based on the control request. The parameter to be controlled can be a predefined parameter, which will not be discussed in detail here.

[0102] In summary, by regulating the equipment corresponding to the to-be-regulated parameter in the air conditioner based on the regulation request, the normal operation of the air conditioner is ensured.

[0103] Based on the same idea, the embodiment of the present specification also provides a device corresponding to the above method, Figure 5 The structure diagram of the air conditioner control device provided by the embodiment of the present application is applied to a controller of an air conditioner, the air conditioner is deployed in a machine room, and the air conditioner comprises a plurality of compressors.
