[0045] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding attached drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0046] Considering that when the set temperature of the computer room air conditioner is set relatively low, it will cause energy waste. In addition, for an air conditioner, the set temperature depends on the user's setting or works with a default value, and generally does not change the set temperature by itself. Instead, it relies on the experience of maintenance personnel to adjust the set temperature of the air conditioner to meet the energy-saving requirements, which undoubtedly increases the workload of maintenance personnel and has relatively high requirements for their experience. There are also drawbacks in practice.

[0047] For example: relying on maintenance personnel to set the status of the air conditioner (such as adjusting the set temperature of the air conditioner). If the maintenance personnel lack experience and set the set temperature of the air conditioner too high in the cooling mode, the local temperature of the room may be too high, resulting in abnormal operation of the computer room equipment; if the set temperature of the air conditioner is set too low, the energy consumption will increase. Moreover, theoretically, the set temperature of the air conditioner can be set to different temperatures according to different seasons, and it is impossible to achieve a complete match by manual adjustment alone.

[0048] Therefore, in order to enable the computer room air conditioner to operate more intelligently, the solution of the present invention proposes a control method, device, computer room air conditioner, storage medium, and computer program product for a computer room air conditioner based on the computer room scenario. Specifically, it is a control method, device, computer room air conditioner, storage medium, and computer program product for the automatic adjustment mode of the working state of a computer room air conditioner, which can realize intelligent adjustment of the current state of the computer room air conditioner according to the actual environmental conditions of the environment where the computer room air conditioner is located, and achieve energy conservation while meeting the equipment cooling requirements in special places such as computer rooms and equipment rooms.

[0049] According to an embodiment of the present invention, there is provided a control method for a computer room air conditioner, as Figure 1 shown in the flowchart of an embodiment of the method of the present invention. There are n devices (such as devices in special places such as computer rooms and equipment rooms) in the environment where the computer room air conditioner is located; in the solution of the present invention, as Figure 1 shown, the control method of the computer room air conditioner includes: step S110 to step S140.

[0050] At step S110, retrieve the current state of the computer room air conditioner recorded by the computer room air conditioner, retrieve the time of the last shutdown of the computer room air conditioner recorded by the computer room air conditioner, and retrieve the set temperature of the computer room air conditioner recorded by the computer room air conditioner; for example: retrieve the operating state of the computer room air conditioner before the last shutdown recorded by the computer room air conditioner and the set temperature of the computer room air conditioner recorded by the computer room air conditioner from the storage module of the controller of the computer room air conditioner.

[0051] At step S120, obtain the temperature of the environment where the computer room air conditioner is located, denoted as the indoor environment temperature of the computer room air conditioner, such as the indoor environment temperature T 内环 ; and obtain the temperature of at least one of the n devices in the environment where the computer room air conditioner is located, denoted as the temperature of m devices of the computer room air conditioner, where m and n are both positive integers and m ≤ n. For example: at m = 3 temperature measurement points of the n devices in the environment where the computer room air conditioner is located, a first temperature probe, a second temperature probe, and a third temperature probe are arranged, and the temperature T 设备1 of the first temperature probe, the temperature T 设备2 of the second temperature probe, and the temperature T 设备3 of the third temperature probe.

[0052] At step S130, control the computer room air conditioner to start and operate in the cooling mode or the heating mode according to the current state of the computer room air conditioner and the time of the last shutdown of the computer room air conditioner; or control the computer room air conditioner to start and operate in the cooling mode or the heating mode according to the current state of the computer room air conditioner and the temperatures of m devices of the computer room air conditioner. Wherein, the cooling mode is the cooling mode of the computer room air conditioner, and the heating mode is the heating mode of the computer room air conditioner. For example: in the case where the computer room air conditioner is powered on and needs to be started, such as when the computer room air conditioner is powered on after a long shutdown and just started, or when the computer room air conditioner reaches the temperature point and shuts down or shuts down due to protection and then starts again, control the computer room air conditioner to start and operate in the cooling mode or the heating mode according to the temperatures of m devices of the computer room air conditioner and the current operating mode of the computer room air conditioner.

[0053] At step S140, when the computer room air conditioner is operating in the cooling mode or the heating mode, adjust the set temperature of the computer room air conditioner according to the indoor environmental temperature of the computer room air conditioner and the device temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner, so as to control the computer room air conditioner to operate according to the new set temperature of the computer room air conditioner. That is, when the computer room air conditioner is operating in the cooling mode or the heating mode, adjust the set temperature of the computer room air conditioner when it is operating in the cooling mode or the heating mode according to the indoor environmental temperature of the computer room air conditioner and the device temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner, so as to control the computer room air conditioner to operate according to the new set temperature of the computer room air conditioner.

[0054] The working principle of the solution of the present invention is as Figure 11 shown. Figure 11 It is a schematic structural diagram of an embodiment of the control system where the computer room air conditioner is located. As Figure 11As shown in the figure, the control system where the computer room air conditioner is located includes: a temperature acquisition device, a control device, and a central controller; the temperature acquisition device is connected to the control device, and the central controller is respectively connected to the control device and the air conditioner unit. The number of air conditioner units can be more than one, and each air conditioner unit can execute the control logic provided by the solution of the present invention. Among them, the temperature acquisition device can include more than one temperature probe, such as the first temperature probe, the second temperature probe, the third temperature probe, etc.; the control device can include an acquisition module (such as an information acquisition module), a processing module (such as an information processing module), and an execution module (such as a control module). In the control device, the information acquisition module mainly reads the basic operation information of the computer room air conditioner through the central control. The basic operation information of the computer room air conditioner includes, but is not limited to, the set temperature of the computer room air conditioner, the indoor environment temperature and outdoor environment temperature collected by the computer room air conditioner, the set air volume of the computer room air conditioner, etc. At least one temperature probe is arranged in the room where the computer room air conditioner is located at a position convenient for detecting the equipment environment temperature in the computer room, and the equipment heat dissipation outlet needs to be avoided to prevent the collected temperature from being falsely high; the control module can send the control signal of the computer room air conditioner through the central control. The control signal of the computer room air conditioner includes, but is not limited to, the control signal of the operation mode, the control signal of the set temperature, the control signal of the set air volume, etc.

[0055] Specifically, the arrangement of the temperature probes is based on the number and heat dissipation conditions of the heating equipment in the room where the computer room air conditioner is located. In a better case, in the current room, find which equipment has the highest temperature nearby, and then arrange a temperature probe at the location of this equipment; secondly, if the temperatures at two positions are both relatively high and it is impossible to simply judge which position has a higher temperature, then two temperature probes can be arranged; even worse, the installer arranges as many temperature probes as there are heating equipment in the room.

[0056] A control solution for the automatic adjustment mode of the working state of a computer room air conditioner proposed by the solution of the present invention is based on the multi-parameter coupling control technology, and adjusts the computer room air conditioner according to the actual load demand of the environment, solves the problem of energy waste caused by setting the set temperature of the computer room air conditioner relatively low, and at the same time solves the problem of energy waste caused by the inability of the computer room air conditioner to automatically adjust the set temperature, improving the user experience and energy-saving effect.

[0057] In software engineering, coupling refers to the dependency relationships and mutual influences between modules, components, or systems. In the solution of the present invention, the multi-parameter coupling control technology refers to the associated control among the control parameters of the air conditioner. When one parameter is adjusted, one or more other parameters are correspondingly adjusted. For example, when the user adjusts the set air volume from the low air volume to the high air volume, it can be understood that the user needs to increase the cooling output of the air conditioner. Therefore, the upper limit of the compressor operating frequency will be relatively increased, and the control parameters of the electronic expansion valve will also be correspondingly adjusted. Performing coupling control can keep the operating state of the air conditioner in the best state.

[0058] In some embodiments, the current state of the computer room air conditioner includes the operating state of the computer room air conditioner before the last shutdown; wherein, the operating state of the computer room air conditioner before the last shutdown is the state when the computer room air conditioner operates in the cooling mode or the heating mode.

[0059] For the specific process of controlling the computer room air conditioner to start up and operate in the cooling mode or the heating mode according to the current state of the computer room air conditioner and the time of the last shutdown of the computer room air conditioner in step S130, refer to the following exemplary description.

[0060] The following combines Figure 2 Shown is a schematic flowchart of an embodiment of controlling the computer room air conditioner to start up and operate according to the current state of the computer room air conditioner and the time of the last shutdown of the computer room air conditioner in the method of the present invention. To further illustrate the specific process of controlling the computer room air conditioner to start up and operate according to the current state of the computer room air conditioner and the time of the last shutdown of the computer room air conditioner in step S130, it includes: step S210 to step S230.

[0061] Step S210, determine whether the first interval time between the time of the last shutdown of the computer room air conditioner and the current time of the computer room air conditioner is less than the first set time.

[0062] Step S220, if it is determined that the first interval time between the time of the last shutdown of the computer room air conditioner and the current time of the computer room air conditioner is less than the first set time, then control the computer room air conditioner to start up and operate according to the operating state of the computer room air conditioner before the last shutdown, that is, control the computer room air conditioner to start up and operate in the operating mode of the computer room air conditioner before the last shutdown.

[0063] Step S230, if it is determined that the time interval between the time of the last shutdown of the computer room air conditioner and the current time of the computer room air conditioner is greater than or equal to the first set time, then control the computer room air conditioner to start up and operate in the cooling mode or the heating mode according to the current state of the computer room air conditioner and the m device temperatures of the computer room air conditioner; wherein, the first set time is, for example, the time when the computer room air conditioner shuts down due to reaching the temperature point or other reasons such as protection shutdown and then starts up again.

[0064] In the solution of the present invention, after adjusting the set temperature of the computer room air conditioner, the current set temperature is memorized as the default set temperature, and the default set temperature is sent when starting up next time. Generally speaking, when the computer room air conditioner stops due to reaching the temperature point or for other reasons such as protection shutdown and then starts up again, the time interval between the two is not particularly long, and the room load change is not too large. Taking the state before the previous shutdown as the initial state of the current startup can avoid the readjustment process in the previous period of time and directly operate in a state that is more matched with the current environment. If the load changes, readjustment is carried out again. This is a better control logic. Among them, the state before the previous shutdown includes the state of the operation mode, the state of the set temperature, the state of the set air volume, etc.

[0065] In some embodiments, the current state of the computer room air conditioner further includes: the state that the computer room air conditioner does not operate in the corresponding mode; the state that the computer room air conditioner does not operate in the corresponding mode is: the state of not operating in the cooling mode or the state of not operating in the heating mode; among them, the state of not operating in the cooling mode, such as the state of shutdown, the state of air supply, the state of operating in the heating mode; the state of not operating in the heating mode, such as the state of shutdown, the state of air supply, the state of operating in the cooling mode.

[0066] For the specific process of controlling the computer room air conditioner to start up and operate in the cooling mode or the heating mode according to the current state of the computer room air conditioner and the m device temperatures of the computer room air conditioner in step S130, refer to the following exemplary description.

[0067] The following combines Figure 3 The schematic flowchart of an embodiment of controlling the computer room air conditioner to start up and operate according to the current state of the computer room air conditioner and the m device temperatures of the computer room air conditioner in the method of the present invention shown, and further illustrates the specific process of controlling the computer room air conditioner to start up and operate according to the current state of the computer room air conditioner and the m device temperatures of the computer room air conditioner in step S130, including: step S310 to step S330.

[0068] Step S310, determine the highest temperature among the m device temperatures of the computer room air conditioner, denoted as the device highest temperature of the computer room air conditioner, such as the device highest temperature T max = max(T 设备1 , T 设备2 , T 设备3 ); and determine the lowest temperature among the m device temperatures of the computer room air conditioner, denoted as the device lowest temperature of the computer room air conditioner, such as T min = min(T 设备1 , T 设备2 , T 设备3 ).

[0069] Step S320: If it is determined that both the maximum temperature of the equipment of the computer room air conditioner is greater than or equal to the upper limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located, and the current state of the computer room air conditioner is a state where the refrigeration mode is not running, then control the computer room air conditioner to start up and run the refrigeration mode; among them, the upper limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located, such as the allowable upper room temperature T 上限 .

[0070] Step S330: If it is determined that both the minimum temperature of the equipment of the computer room air conditioner is less than or equal to the lower limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located, and the current state of the computer room air conditioner is a state where the heating mode is not running, then control the computer room air conditioner to start up and run the heating mode. Among them, the lower limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located, such as the allowable lower room temperature T 下限 .

[0071] Figure 12 is a schematic diagram of the control process for starting up and operating modes of the computer room air conditioner. As Figure 12 shown, the control process for starting up and operating modes of the computer room air conditioner includes:

[0072] Step 11: Read the current state of the computer room air conditioner, the set air volume of the indoor fan, the set temperature T 设定 , the indoor environment temperature T 内环 , and the operating state of the compressor, and then execute Step 12. The set temperature T 设定 includes the set temperature T 制冷设定 and the set temperature T 制热设定 .

[0073] In Step 11, the current state of the computer room air conditioner, such as the state of shutdown, refrigeration, heating, air supply, etc. The set air volume of the indoor fan, such as the high gear of the indoor fan, the medium gear of the indoor fan, the low gear of the indoor fan, etc. The operating state of the compressor, such as the state where the compressor is turned on, the state where the compressor is turned off.

[0074] Step 12: Execute the control logic for starting up the air conditioner, specifically including Step 121, Step 122, and Step 123.

[0075] Step 121: Read the temperature T 设备1 of the first temperature probe, the temperature T 设备2 of the second temperature probe, and the temperature T 设备3 of the third temperature probe, and assign T max = max(T 设备1 , T 设备2 , T 设备3 ); Tmin = min(T 设备1 , T 设备2 , T 设备3 ), that is, the highest temperature of the collected device is T max , and the lowest temperature of the collected device is T min . Then, step 122 is executed. Of course, if only one temperature probe is arranged, then T max = T min = T 设备1 .

[0076] Among them, the first temperature probe, the second temperature probe, and the third temperature probe refer to the above-mentioned additionally arranged temperature probes, which are generally used to detect the temperatures of different devices. In addition, the maximum number here is not limited to 3 temperature probes. For a general computer room, it is more economical to add 1 to 3 temperature probes.

[0077] Step 122: Determine whether the following conditions are simultaneously satisfied, such as the highest temperature of the device T max ≥ T 上限 , and the operating mode of the computer room air conditioner is in the non-cooling mode: If so, control the computer room air conditioner to start cooling operation; otherwise, execute step 123. After the computer room air conditioner starts cooling operation, it will automatically adjust and control. For specific examples, please refer to Figure 13 the example shown.

[0078] In step 122, when it is detected that the highest temperature of the device T max ≥ T 上限 , if the air conditioner is in the non-cooling state, a cooling instruction is sent to the computer room air conditioner; at this time, the set temperature T 制冷设定 of the computer room air conditioner is the default value. Among them, T 上限 is the allowable upper limit temperature of the room, that is, the upper limit of the working environment temperature of the computer room equipment, with a value range of 30°C to 40°C, preferably 38°C. This value can be adjusted by the user setting.

[0079] Step 123: Determine whether the following conditions are simultaneously satisfied, such as the lowest temperature of the device T min ≤ T 下限 , and the operating mode of the computer room air conditioner is in the non-heating mode: If so, control the computer room air conditioner to start heating operation; otherwise, end the current determination. After the computer room air conditioner starts heating operation, it will automatically adjust and control. For specific examples, please refer to Figure 14 the example shown.

[0080] In step 123, when it is detected that the lowest temperature of the device T min ≤ T 下限 , if the air conditioner is in the non-heating state, a heating instruction is sent to the air conditioner; at this time, the set temperature T 制热设定 of the computer room air conditioner is the default value. T 下限is the allowable lower limit temperature of the room, that is, the lower limit of the operating environment temperature of the computer room equipment, with a value range of -10 to 10 °C, preferably 2 °C, and this value can be adjusted by user settings.

[0081] Generally speaking, the operating temperature of computer room equipment is suitable below 40 °C. Too high a temperature will affect the reliability of the equipment, and too low a temperature is likely to cause embrittlement of plastic products in the computer room. Therefore, the heating mode will be turned on when the temperature is below 0 °C. The heat dissipation of the equipment is that the equipment transfers heat to the environment through the built-in fan of the equipment, the room temperature rises, and then the air conditioner cools down the room temperature, thereby indirectly cooling the equipment. Therefore, the ambient temperature around the equipment is related to the heat dissipation capacity of the computer room equipment itself and the location of the computer room air conditioner, etc. However, generally in the relatively stable state, the temperature distribution in the room is relatively balanced, and the difference between the air temperature at the air inlet of the computer room air conditioner and the air temperature near the equipment in the room is relatively stable. Therefore, the temperature near the equipment and the temperature at the air inlet of the computer room air conditioner can be detected, and the set temperature of the computer room air conditioner can be controlled according to the temperature near the equipment and the temperature at the air inlet of the computer room air conditioner, so as to make the set temperature of the computer room air conditioner in an energy-saving state. In addition, since the computer room air conditioner is a centrally purchased product, the communication protocol between the products of each air conditioner manufacturer and the central control is developed according to the established protocol. Therefore, for air conditioner products of different manufacturers, the basic settings such as the set temperature of the air conditioner can be set through the central control.

[0082] In the solution of the present invention, according to the operating mode of the computer room air conditioner and the highest temperature T of the equipment max and the lowest temperature T of the equipment min controlling the startup and cooling or heating operation of the computer room air conditioner can make the ambient temperature of the room where the computer room air conditioner is located reach the suitable operating temperature of the equipment in the room where the computer room air conditioner is located, and ensure the safety of the equipment in the room where the computer room air conditioner is located.

[0083] In the solution of the present invention, the control device corresponding to the control scheme of the automatic adjustment mode of the working state of the computer room air conditioner can be set and configured separately to control the set states of air conditioners of different manufacturers, or can be integrated into the air conditioner to achieve self-intelligent control of the air conditioner. The control logic of the control scheme of the automatic adjustment mode of the working state of the computer room air conditioner can be integrated in the controller of the computer room air conditioner at the factory, or can be integrated in a device separated from the computer room air conditioner. Using this device can control air conditioners of different brands and models, and has a wider application range. The control parameters involved in the solution of the present invention are all parameters that are default open to users in the industry and can be adjusted using a remote control or other control tools (such as the panel of the computer room air conditioner, the upper computer, etc.). Therefore, the device integrating the control logic of the solution of the present invention can control all computer room air conditioners to achieve energy-saving effects. The user does not need to modify the computer room air conditioner, and it has a large market application prospect.

[0084] In some embodiments, when the computer room air conditioner operates in the cooling mode or the heating mode in step S140, the set temperature of the computer room air conditioner is adjusted according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner, including: when the computer room air conditioner operates in the cooling mode, the set temperature of the computer room air conditioner is adjusted according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner; or, when the computer room air conditioner operates in the heating mode, the set temperature of the computer room air conditioner is adjusted according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner. Among them, when the computer room air conditioner operates in the cooling mode, the set temperature of the computer room air conditioner is adjusted according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner, including: the first process of adjusting the set temperature of the computer room air conditioner in the cooling mode.

[0088] Step S430, when the computer room air conditioner operates in the cooling mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is less than or equal to the first preset temperature, then determine whether the difference between the highest equipment temperature of the computer room air conditioner and the upper limit of the preset working environmental temperature range of n equipment in the environment where the computer room air conditioner is located is greater than the first preset temperature.

[0089] Step S440: When the computer room air conditioner is operating in the cooling mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is less than or equal to the first preset temperature, and if it is determined that the difference between the highest equipment temperature of the computer room air conditioner and the upper limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than the first preset temperature, then reduce the set temperature of the computer room air conditioner by the second preset temperature to be the new set temperature of the computer room air conditioner, and record the new set temperature of the computer room air conditioner; wherein, the second preset temperature is greater than the first preset temperature, and the second preset temperature is, for example, 1°C.

[0090] Figure 13 It is a schematic diagram of the control process of the computer room air conditioner in the cooling mode. As Figure 13 shown, the control process of the computer room air conditioner in the cooling mode includes:

[0091] Step 21: When the computer room air conditioner is in the cooling mode and the compressor is turned on, determine whether it satisfies the indoor environmental temperature T 内环 -T 制冷设定 : If so, execute Step 22; otherwise, maintain the current state unchanged.

[0092] Step 22: When the indoor environmental temperature T 内环 -T 制冷设定 ≤0°C, determine whether it satisfies T max -T 上限 >0°C: If so, execute Step 23; otherwise, execute Step 24.

[0093] Step 23: When it is detected that T max -T 上限 >0°C, then T 制冷设定 = current setting - 1°C, to increase the air conditioner's cooling capacity output and achieve the effect of rapid cooling.

[0094] In some embodiments, in Step S140, when the computer room air conditioner is operating in the cooling mode, according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner, adjusting the set temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner further includes: the second process of adjusting the set temperature of the computer room air conditioner in the cooling mode.

[0103] Step 26, determine whether it satisfies (T 上限 -A)-T max <0: If so, execute Step 27, otherwise maintain the current state unchanged.

[0104] Step 27, if (T 上限 -A)-T max <0, then set T制冷设定 = Current setting - 1°C.

[0105] In Figure 13 the example shown, when the indoor ambient temperature T 内环 - T 制冷设定 ≤ 0°C, it indicates that the computer room air conditioner believes that the output has reached equilibrium. At this time, the computer room air conditioner generally maintains the current state unchanged or reduces the output to achieve energy conservation. Further, if (T 上限 - A) - T max ≥ 1°C, it means that there is more than 1°C of space between the highest ambient temperature around the equipment in the room and the warning temperature (the reserved margin A has been considered). Then, the set temperature of the computer room air conditioner can be increased by 1°C on the current basis to save air conditioner energy consumption; if (T 上限 - A) - T max <0, it means that there is no margin left between the highest room temperature and the warning temperature, and the set temperature of the computer room air conditioner needs to be lowered to reduce the room temperature; if 0 ≤ (T 上限 - A) - T max <1°C, it means that there is a certain distance but not too large a gap between the highest room temperature and the warning temperature, and it is in a state with relatively good comprehensive performance of energy conservation and reliability. Then, the current operating state is maintained unchanged.

[0106] In some embodiments, in step S140, when the computer room air conditioner is operating in the cooling mode or the heating mode, according to the indoor ambient temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner, the set temperature of the computer room air conditioner is adjusted to obtain the new set temperature of the computer room air conditioner. It further includes: when the computer room air conditioner is operating in the heating mode, according to the indoor ambient temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner, the set temperature of the computer room air conditioner is adjusted to obtain the new set temperature of the computer room air conditioner. Among them, when the computer room air conditioner is operating in the heating mode, according to the indoor ambient temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner, the set temperature of the computer room air conditioner is adjusted to obtain the new set temperature of the computer room air conditioner, including: the first process of adjusting the set temperature of the computer room air conditioner in the heating mode.

[0107] The following combines Figure 6 a schematic flowchart of an embodiment of the first process of adjusting the set temperature of the computer room air conditioner in the heating mode in the method of the present invention shown, and further illustrates the specific process of the first process of adjusting the set temperature of the computer room air conditioner in the heating mode in step S140, including: steps S610 to S640.

[0110] Step S630, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environment temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature, then determine whether the difference between the lowest device temperature of the computer room air conditioner and the lower limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located is less than the first preset temperature.

[0111] Step S640, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, in the case where it is determined that the difference between the indoor environment temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature, if it is determined that the difference between the lowest device temperature of the computer room air conditioner and the lower limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located is less than the first preset temperature, then increase the set temperature of the computer room air conditioner by a second preset temperature as the new set temperature of the computer room air conditioner, and record the new set temperature of the computer room air conditioner; wherein, the second preset temperature is greater than the first preset temperature, and the second preset temperature is, for example, 1°C.

[0112] Figure 14 is a schematic diagram of the control process of the computer room air conditioner in the heating mode. As Figure 14 shown, the control process of the computer room air conditioner in the heating mode includes:

[0113] Step 31: When the air conditioner is in the heating mode and the compressor is on, determine whether it satisfies the condition that the indoor environment temperature T 内环 - T 制热设定 ≥ 0°C: If so, execute Step 32; otherwise, maintain the current state unchanged.

[0114] Step 32: When the indoor environment temperature T 内环 - T 制热设定 ≥ 0°C, determine whether it satisfies T min - T 下限<0 °C: If yes, execute step 33; otherwise, execute step 34.

[0115] Step 33: When it is detected that T min -T 下限 <0 °C, then T 制热设定 = current setting + 1 °C to increase the heating capacity output of the air conditioner and achieve the effect of rapid temperature rise.

[0116] In some embodiments, when the computer room air conditioner is operating in the heating mode in step S140, according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner, adjusting the set temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner further includes: a second process of adjusting the set temperature of the computer room air conditioner in the heating mode.

[0117] The following combines Figure 7 A schematic flowchart of an embodiment of the second process of adjusting the set temperature of the computer room air conditioner in the heating mode in the method of the present invention as shown, further illustrating the specific process of the second process of adjusting the set temperature of the computer room air conditioner in the heating mode in step S140, including: step S710 to step S750.

[0118] Step S710, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature, and if it is determined that the difference between the lowest equipment temperature of the computer room air conditioner and the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than or equal to the first preset temperature, then determine the sum value between the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located and the second preset temperature margin, denoted as the first sum value; and determine whether the difference between the lowest equipment temperature of the computer room air conditioner and the first sum value is greater than or equal to the first temperature threshold; wherein, the second preset temperature margin is such as the margin constant B.

[0119] Step S720, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature and it is determined that the difference between the lowest equipment temperature of the computer room air conditioner and the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than or equal to the first preset temperature, and if it is determined that the difference between the lowest equipment temperature of the computer room air conditioner and the first sum value is greater than or equal to the first temperature threshold, then reduce the set temperature of the computer room air conditioner by the second preset temperature as the new set temperature of the computer room air conditioner, and record the new set temperature of the computer room air conditioner.

[0120] Step S730, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature, and it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than or equal to the first preset temperature, and if it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the first sum value is less than the first temperature threshold, then determine whether the difference between the lowest temperature of the equipment of the computer room air conditioner and the first sum value is less than or equal to the negative second preset temperature.

[0121] Step S740, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature, it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than or equal to the first preset temperature, and it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the first sum value is less than the first temperature threshold, and if it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the first sum value is less than or equal to the negative second preset temperature, then increase the set temperature of the computer room air conditioner by the second preset temperature as the new set temperature of the computer room air conditioner, and record the new set temperature of the computer room air conditioner.

[0122] Step S750, when the computer room air conditioner is operating in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to the first preset temperature, it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than or equal to the first preset temperature, and it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the first sum value is less than the first temperature threshold, and if it is determined that the difference between the lowest temperature of the equipment of the computer room air conditioner and the first sum value is greater than the negative second preset temperature, then maintain the set temperature of the computer room air conditioner, that is, use the set temperature of the computer room air conditioner as the new set temperature of the computer room air conditioner, and record the new set temperature of the computer room air conditioner.

[0123] As Figure 14 shown, the control process of the computer room air conditioner in the heating mode further includes:

[0124] Step 34, determine whether it satisfies T min -(T 下限+B) > 0: If so, execute step 35; otherwise, execute step 36. Here, B is a margin constant, and its value range is 0°C to 5°C, preferably 1°C.

[0125] Step 35: If T min -(T 下限 +B) > 0, then set T 制热设定 = current setting - 1°C.

[0126] Step 36: Determine whether it satisfies T min -(T 下限 +B) ≤ -1°C: If so, execute step 37; otherwise, maintain the current state unchanged.

[0127] Step 37: If T min -(T 下限 +B) ≤ -1°C, then set T 设定 = current setting + 1°C.

[0128] In Figure 14 the example shown, the heating principle is the same as the cooling. When it is detected that there is a distance between the lowest temperature and the lower limit warning temperature, the heating set temperature is reduced to save energy; when the temperature is too low, the set temperature is increased to raise the room temperature and improve reliability.

[0129] In the solution of the present invention, in combination with the room equipment temperature (such as the temperature T 设备1 of the first temperature probe, the temperature T 设备2 of the second temperature probe, the temperature T 设备3 of the third temperature probe) and the air return temperature of the air conditioner (such as the indoor environment temperature T 内环 ), when the air return temperature of the air conditioner is close to the set temperature, the difference between the equipment environment temperature and the target value is judged, and the set state of the air conditioner is controlled to achieve the purpose of energy saving. The solution of the present invention mainly detects whether the actual environment temperature of the equipment is at the energy-saving expected temperature when the room temperature is close to the air conditioner set temperature. If it is lower than the expected value, the air conditioner set temperature can be increased; and it is independent of the position and distance of the temperature probe, with simple and effective control and strong general applicability.

[0130] In some embodiments, the control method of the computer room air conditioner described in the solution of the present invention further includes: the process of dynamically adjusting the set temperature of the computer room air conditioner at intervals.

[0131] Next, in combination with Figure 8 the schematic flow chart of an embodiment of dynamically adjusting the set temperature of the computer room air conditioner at intervals in the method of the present invention shown, the specific process of dynamically adjusting the set temperature of the computer room air conditioner at intervals is further described, including: step S810 to step S820.

[0132] Step S810, when the computer room air conditioner is operating in the cooling mode or the heating mode, after adjusting the set temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner, start timing to obtain the second interval time.

[0133] Step S820, after the second interval time reaches the second set time, readjust the set temperature of the computer room air conditioner according to the indoor environmental temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner again, and obtain the new set temperature of the computer room air conditioner again, so as to control the computer room air conditioner to operate according to the newly obtained set temperature of the computer room air conditioner. Among them, the second set time is like time t 0 。

[0134] In the solution of the present invention, when the set temperature of the computer room air conditioner changes, it is necessary to judge and update the set temperature of the computer room air conditioner again at least after t 0 time (t 0 The value range is 5 min to 30 min, preferably 20 min). After adjusting the set temperature of the computer room air conditioner, the output of the computer room air conditioner and the change of the room temperature do not respond so quickly. If the adjustment time interval is too short, it is easy to cause over-adjustment. Generally speaking, 20 min can make the computer room air conditioner and the room temperature reach a stable state again.

[0135] In some embodiments, the control method of the computer room air conditioner according to the solution of the present invention further includes: the process of controlling the air volume gear of the indoor fan of the computer room air conditioner.

[0136] The current state of the computer room air conditioner further includes: the state of the air volume gear of the indoor fan of the computer room air conditioner before the computer room air conditioner last stopped; the state of the air volume gear of the indoor fan of the computer room air conditioner before the computer room air conditioner last stopped is the state of the indoor fan operating at any one of the preset maximum air volume gear, the preset medium air volume gear, and the preset minimum air volume gear.

[0137] The following combines Figure 9 The schematic flow chart of an embodiment of controlling the air volume gear of the indoor fan of the computer room air conditioner in the method of the present invention shown, and further describes the specific process of controlling the air volume gear of the indoor fan of the computer room air conditioner, including: Step S910 to Step S930.

[0138] Step S910, determine whether the first interval time between the time when the computer room air conditioner last stopped and the current time of the computer room air conditioner is less than the first set time.

[0139] Step S920, if it is determined that the first interval between the time when the computer room air conditioner last stopped and the current time of the computer room air conditioner is greater than or equal to the first set time, then when the computer room air conditioner is operating in the cooling mode or the heating mode, control the air volume gear of the indoor fan of the computer room air conditioner to the preset maximum air volume gear.

[0140] Step S930, if it is determined that the first interval between the time when the computer room air conditioner last stopped and the current time of the computer room air conditioner is less than the first set time, then when the computer room air conditioner is operating in the cooling mode or the heating mode, control the state of the air volume gear of the indoor fan of the computer room air conditioner to the state of the air volume gear of the indoor fan of the computer room air conditioner before the computer room air conditioner last stopped.

[0141] In the solution of the present invention, since the computer room environment has low requirements for noise, the air volume gear is generally set to the highest air volume gear to improve the heat exchange efficiency.

[0142] The solution of the present invention can intelligently adjust the current state of the computer room air conditioner according to the actual environmental conditions of the environment where the computer room air conditioner is located, achieve energy saving while meeting the equipment cooling requirements in special places such as computer rooms and equipment rooms, solve the problem of single control of computer room air conditioners and inability to intelligently balance the cooling requirements and energy saving requirements in scenario applications, and improve the user experience and energy saving effect.

[0143] Adopting the technical solution of this embodiment, for the computer room air conditioner, obtain the temperature in the environment where the computer room air conditioner is located and record it as the indoor environmental temperature (such as the temperature of the return air outlet of the computer room air conditioner), and obtain the temperature of the equipment in the environment where the computer room air conditioner is located and record it as the equipment temperature (such as the temperature of the temperature probe at the equipment temperature measurement point arranged in the environment where the computer room air conditioner is located). Determine whether the computer room air conditioner starts to operate in the cooling mode or the heating mode according to the equipment temperature and the current operating mode of the computer room air conditioner. After the computer room air conditioner starts to operate in the cooling mode or the heating mode, adjust the set temperature of the computer room air conditioner according to the indoor environmental temperature and the equipment temperature; thus, combining the equipment temperature and the indoor environmental temperature of the computer room air conditioner, control the computer room air conditioner to operate in the cooling or heating mode, and dynamically adjust the set temperature of the computer room air conditioner to save energy.

[0144] According to an embodiment of the present invention, there is also provided a control device for a computer room air conditioner corresponding to the control method of the computer room air conditioner. Refer to Figure 10 The structural schematic diagram of an embodiment of the device of the present invention shown. There are n devices in the environment where the computer room air conditioner is located (such as the devices in special places such as computer rooms and equipment rooms); in the solution of the present invention, as Figure 10 shown, the control device of the computer room air conditioner includes: an acquisition unit 102 and a control unit 104.

[0145] Among them, the obtaining unit 102 is configured to retrieve the current state of the computer room air conditioner recorded by the computer room air conditioner, retrieve the time of the last shutdown of the computer room air conditioner recorded by the computer room air conditioner, and retrieve the set temperature of the computer room air conditioner recorded by the computer room air conditioner; for example: retrieve the operating state of the computer room air conditioner before the last shutdown recorded by the computer room air conditioner and the set temperature of the computer room air conditioner recorded by the computer room air conditioner from the storage module of the controller of the computer room air conditioner. For the specific functions and processing of this obtaining unit 102, refer to step S110.

[0146] The obtaining unit 102 is further configured to obtain the temperature of the environment where the computer room air conditioner is located, denoted as the indoor environment temperature of the computer room air conditioner, such as the indoor environment temperature T 内环 ; and obtain the temperatures of at least one of the n devices in the environment where the computer room air conditioner is located, denoted as the temperatures of m devices of the computer room air conditioner, where both m and n are positive integers and m ≤ n. For example: at m = 3 temperature measurement points of the n devices in the environment where the computer room air conditioner is located, a first temperature probe, a second temperature probe, and a third temperature probe are arranged, and the temperature T of the first temperature probe 设备1 , the temperature T of the second temperature probe 设备2 , and the temperature T of the third temperature probe 设备3 . For the specific functions and processing of this obtaining unit 102, also refer to step S120.

[0147] The control unit 104 is configured to control the computer room air conditioner to start up and operate in a cooling mode or a heating mode according to the current state of the computer room air conditioner and the time of the last shutdown of the computer room air conditioner; or, control the computer room air conditioner to start up and operate in a cooling mode or a heating mode according to the current state of the computer room air conditioner and the temperatures of the m devices of the computer room air conditioner. For example: in the case where the computer room air conditioner is powered on and needs to be started up, such as when the computer room air conditioner is powered on after a long shutdown and just starts up, or when the computer room air conditioner reaches the temperature point and shuts down or shuts down due to protection and then starts up again, control the computer room air conditioner to start up and operate in a cooling mode or a heating mode according to the temperatures of the m devices of the computer room air conditioner and the current operating mode of the computer room air conditioner. For the specific functions and processing of this control unit 104, also refer to step S130.

[0148] The control unit 104 is further configured to, when the computer room air conditioner operates in the cooling mode or the heating mode, adjust the set temperature of the computer room air conditioner according to the indoor environmental temperature of the computer room air conditioner and the device temperature of the computer room air conditioner, so as to obtain the new set temperature of the computer room air conditioner, and control the computer room air conditioner to operate according to the new set temperature of the computer room air conditioner. That is, the control unit 104 is further configured to, when the computer room air conditioner operates in the cooling mode or the heating mode, adjust the set temperature of the computer room air conditioner when it operates in the cooling mode or the heating mode according to the indoor environmental temperature of the computer room air conditioner and the device temperature of the computer room air conditioner, so as to obtain the new set temperature of the computer room air conditioner, and control the computer room air conditioner to operate according to the new set temperature of the computer room air conditioner. For the specific functions and processes of this control unit 104, refer to step S140.

[0149] The working principle of the solution of the present invention is as Figure 11 shown. Figure 11 It is a schematic structural diagram of an embodiment of the control system where the computer room air conditioner is located. As Figure 11 shown, the control system where the computer room air conditioner is located includes: a temperature acquisition device, a control device, and a central controller; the temperature acquisition device is connected to the control device, the central controller is respectively connected to the control device and the air conditioner unit, and the number of air conditioner units can be more than one, and each air conditioner unit can execute the control logic provided by the solution of the present invention. Among them, the temperature acquisition device can include more than one temperature probe, such as a first temperature probe, a second temperature probe, a third temperature probe, etc.; the control device can include an acquisition module (such as an information acquisition module), a processing module (such as an information processing module), and an execution module (such as a control module). In the control device, the information acquisition module mainly reads the basic operation information of the computer room air conditioner through the central control, and the basic operation information of the computer room air conditioner includes but is not limited to the set temperature of the computer room air conditioner, the indoor environmental temperature and the outdoor environmental temperature collected by the computer room air conditioner, the set air volume of the computer room air conditioner, etc. At least one temperature probe is arranged in the room where the computer room air conditioner is located at a position convenient for detecting the equipment environment temperature of the computer room, and the equipment heat dissipation outlet needs to be avoided to prevent the collected temperature from being falsely high; the control module can send the control signal of the computer room air conditioner through the central control, and the control signal of the computer room air conditioner includes but is not limited to the control signal of the operation mode, the control signal of the set temperature, the control signal of the set air volume, etc.

[0150] Specifically, the temperature probes are arranged according to the number and heat dissipation conditions of the heat-generating devices in the room where the computer room air conditioner is located. In a better case, in the current room, find which device has the highest temperature nearby, and then arrange a temperature probe at the location of that device; second, if the temperatures at two positions are relatively high and it is impossible to simply determine which position has a higher temperature, then two temperature probes can be arranged; even worse, the installer arranges as many temperature probes as there are heat-generating devices in the room.

[0151] A control scheme for the automatic adjustment mode of the operating state of a computer room air conditioner proposed by the solution of the present invention, based on the multi-parameter coupling control technology, adjusts the computer room air conditioner according to the actual load demand of the environment, solves the problem of energy waste caused by setting the set temperature of the computer room air conditioner relatively low, and at the same time solves the problem of energy waste caused by the inability of the computer room air conditioner to automatically adjust the set temperature, improving the user experience and energy-saving effect.

[0152] In some embodiments, the current state of the computer room air conditioner includes: the operating state of the computer room air conditioner before the last shutdown; wherein, the operating state of the computer room air conditioner before the last shutdown is the state in which the computer room air conditioner operates in the cooling mode or the heating mode.

[0153] The control unit 104 controls the computer room air conditioner to start and operate in the cooling mode or the heating mode according to the current state of the computer room air conditioner and the time of the last shutdown of the computer room air conditioner, including:

[0154] The control unit 104 is specifically further configured to determine whether a first interval time between the time of the last shutdown of the computer room air conditioner and the current time of the computer room air conditioner is less than a first set time. The specific functions and processes of this control unit 104 are also referred to in step S210.

[0155] The control unit 104 is specifically further configured to, if it is determined that the first interval time between the time of the last shutdown of the computer room air conditioner and the current time of the computer room air conditioner is less than the first set time, then control the computer room air conditioner to start and operate in the operating state before the last shutdown of the computer room air conditioner, that is, control the computer room air conditioner to start and operate in the operating mode before the last shutdown of the computer room air conditioner. The specific functions and processes of this control unit 104 are also referred to in step S220.

[0156] The control unit 104 is specifically further configured to, if it is determined that the time interval between the time when the computer room air conditioner last stopped and the current time of the computer room air conditioner is greater than or equal to a first set time, control the computer room air conditioner to start up and operate in a cooling mode or a heating mode according to the current state of the computer room air conditioner and the m device temperatures of the computer room air conditioner; wherein, the first set time is, for example, the time when the computer room air conditioner starts up again after stopping due to reaching a temperature point or other reasons such as protection shutdown. For the specific functions and processes of this control unit 104, refer to step S230 for details.

[0157] In the solution of the present invention, after adjusting the set temperature of the computer room air conditioner, the current set temperature is memorized as the default set temperature, and this default set temperature is sent during the next startup. Generally speaking, when the computer room air conditioner stops due to reaching a temperature point or other reasons such as protection shutdown and then starts up again, the time interval between the two is not particularly far, and the room load change is not too large. Using the state before the last shutdown as the initial state for the current startup can avoid the readjustment process in the previous period of time and directly operate in a state that is more matched to the current environment. If the load changes, readjustment is carried out again. This is a relatively optimal control logic. Among them, the state before the last shutdown includes states such as the operating mode state, the set temperature state, and the set air volume state.

[0158] In some embodiments, the current state of the computer room air conditioner further includes: the state where the computer room air conditioner does not operate in a corresponding mode; the state where the computer room air conditioner does not operate in a corresponding mode is: the state of not operating in the cooling mode or the state of not operating in the heating mode; among them, the state of not operating in the cooling mode is, for example, the shutdown state, the air supply state, or the state of operating in the heating mode; the state of not operating in the heating mode is, for example, the shutdown state, the air supply state, or the state of operating in the cooling mode.

[0159] The control unit 104 controls the computer room air conditioner to start up and operate in a cooling mode or a heating mode according to the current state of the computer room air conditioner and the m device temperatures of the computer room air conditioner, including:

[0160] The control unit 104 is specifically further configured to determine the highest temperature among the m device temperatures of the computer room air conditioner, denoted as the device highest temperature of the computer room air conditioner, such as the device highest temperature T max = max(T 设备1 、T 设备2 、T 设备3 ); and determine the lowest temperature among the m device temperatures of the computer room air conditioner, denoted as the device lowest temperature of the computer room air conditioner, such as T min = min(T 设备1 、T 设备2 、T 设备3)。The specific functions and processing of the control unit 104 are also described in step S310.

[0161] The control unit 104 is specifically further configured to control the computer room air conditioner to start up and operate in the cooling mode if it is determined that both the highest temperature of the equipment of the computer room air conditioner is greater than or equal to the upper limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located and the current state of the computer room air conditioner is a state of not operating in the cooling mode; wherein, the upper limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located, such as the allowable upper room temperature T 上限 。The specific functions and processing of the control unit 104 are also described in step S320.

[0162] The control unit 104 is specifically further configured to control the computer room air conditioner to start up and operate in the heating mode if it is determined that both the lowest temperature of the equipment of the computer room air conditioner is less than or equal to the lower limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located and the current state of the computer room air conditioner is a state of not operating in the heating mode. Wherein, the lower limit of the preset working environment temperature range of n devices in the environment where the computer room air conditioner is located, such as the allowable lower room temperature T 下限 。The specific functions and processing of the control unit 104 are also described in step S330.

[0163] Figure 12 is a schematic diagram of the control process for the startup and operation mode of the computer room air conditioner. As Figure 12 shown, the control process for the startup and operation mode of the computer room air conditioner includes:

[0164] Step 11, read the current state of the computer room air conditioner, the set air volume of the indoor fan, the set temperature T 设定 , the indoor environment temperature T 内环 , the operating state of the compressor, and then execute step 12. The set temperature T 设定 includes the set temperature T 制冷设定 and the set temperature T 制热设定 .

[0165] In step 11, the current state of the computer room air conditioner, such as the state of being shut down, the state of cooling, the state of heating, the state of air supply, etc. The set air volume of the indoor fan, such as the high gear of the indoor fan, the medium gear of the indoor fan, the low gear of the indoor fan, etc. The operating state of the compressor, such as the state of the compressor being turned on, the state of the compressor being turned off.

[0166] Step 12, execute the control logic for starting up the air conditioner, specifically including step 121, step 122, and step 123.

[0167] Step 121, read the temperature T of the first temperature probe 设备1, the temperature T of the second temperature probe 设备2 , the temperature T of the third temperature probe 设备3 , assign T max = max(T 设备1 、T 设备2 、T 设备3 ); T min = min(T 设备1 、T 设备2 、T 设备3 ), that is, the highest temperature of the collected device is T max , the lowest temperature of the collected device is T min , and then step 122 is executed. Of course, if only one temperature probe is arranged, then T max = T min = T 设备1 .

[0168] Among them, the first temperature probe, the second temperature probe, and the third temperature probe refer to the above-mentioned additionally arranged temperature probes, which are generally used to detect the temperatures of different devices; in addition, there are at most no more than 3 temperature probes here. For an ordinary computer room, it is more economical to add 1 - 3 temperature probes.

[0169] Step 122, determine whether the following conditions are simultaneously met, such as the highest temperature of the device T max ≥ T 上限 , and the operating mode of the computer room air conditioner is in the non-cooling mode: if so, control the computer room air conditioner to start cooling operation, otherwise execute step 123. After the computer room air conditioner starts cooling operation, it will automatically adjust and control. For specific examples, please refer to Figure 13 shown in the example.

[0170] In step 122, when it is detected that the highest temperature of the device T max ≥ T 上限 , if the air conditioner is in the non-cooling state, send a cooling instruction to the computer room air conditioner; at this time, the set temperature T 制冷设定 of the computer room air conditioner is the default value. Among them, T 上限 is the allowable upper limit temperature of the room, that is, the upper limit of the working environment temperature of the computer room equipment, with a value range of 30°C to 40°C, preferably 38°C. This value can be adjusted by user settings.

[0171] Step 123, determine whether the following conditions are simultaneously met, such as the lowest temperature of the device T min ≤ T 下限 , and the operating mode of the computer room air conditioner is in the non-heating mode: if so, control the computer room air conditioner to start heating operation, otherwise end the current judgment. After the computer room air conditioner starts heating operation, it will automatically adjust and control. For specific examples, please refer to Figure 14 shown in the example.

[0172] In step 123, when it is detected that the lowest temperature of the device Tmin ≤T 下限 If the air conditioner is not in the heating state, a heating instruction is sent to the air conditioner; at this time, the set temperature T of the computer room air conditioner 制热设定 is the default value. T 下限 is the allowable lower limit temperature of the room, that is, the lower limit of the working environment temperature of the computer room equipment, with a value range of -10 to 10 °C, preferably 2 °C, and this value can be adjusted by user settings.

[0173] Generally speaking, the working temperature of computer room equipment is suitable below 40 °C. Too high a temperature will affect the reliability of the equipment, and too low a temperature is likely to cause embrittlement of plastic products in the computer room. Therefore, the heating mode will be turned on when the temperature is below 0 °C. The heat dissipation of the equipment is that the equipment transfers heat to the environment through the built-in fan of the equipment, the room temperature rises, and then the air conditioner cools down the room temperature, thereby indirectly cooling the equipment. Therefore, the ambient temperature around the equipment is related to the heat dissipation capacity of the computer room equipment itself and the location of the computer room air conditioner, etc. However, generally in the relatively stable state, the temperature distribution in the room is relatively balanced, and the difference between the air temperature at the air inlet of the computer room air conditioner and the air temperature near the equipment in the room is relatively stable. Therefore, the temperature near the equipment and the temperature at the air inlet of the computer room air conditioner can be detected, and the set temperature of the computer room air conditioner can be controlled according to the temperature near the equipment and the temperature at the air inlet of the computer room air conditioner, so as to make the set temperature of the computer room air conditioner in an energy-saving state. In addition, since the computer room air conditioner is a centrally purchased product, the communication protocol between the products of each air conditioner manufacturer and the central control is developed according to the established protocol. Therefore, for air conditioner products of different manufacturers, the basic settings such as the set temperature of the air conditioner can be set through the central control.

[0174] In the solution of the present invention, according to the operating mode of the computer room air conditioner and the highest temperature T of the equipment max and the lowest temperature T of the equipment min controlling the startup and cooling or heating operation of the computer room air conditioner can make the ambient temperature of the room where the computer room air conditioner is located reach the appropriate working temperature of the equipment in the room where the computer room air conditioner is located, and ensure the safety of the equipment in the room where the computer room air conditioner is located.

[0175] In the solution of the present invention, the control device corresponding to the control solution of the automatic adjustment mode of the operating state of the computer room air conditioner can be set and configured separately to control the set states of air conditioners of different manufacturers, or can be integrated into the air conditioner to achieve self-intelligent control of the air conditioner. The control logic of the control solution of the automatic adjustment mode of the operating state of the computer room air conditioner can be integrated into the controller of the computer room air conditioner at the time of leaving the factory, or can be integrated into a device and separated from the computer room air conditioner. Using this device, air conditioners of different brands and models can be controlled, and the application range is wider. The control parameters involved in the solution of the present invention are all parameters that are default open to users in the industry and can be adjusted using a remote control or other control tools (such as the panel of the computer room air conditioner, the upper computer, etc.). Therefore, the device integrating the control logic of the solution of the present invention can control all computer room air conditioners to achieve energy-saving effects. The user does not need to transform the computer room air conditioner, and it has a large market application prospect.

[0188] The control unit 104 is further specifically configured such that when the computer room air conditioner operates in the cooling mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is less than or equal to the first preset temperature, and it is determined that the difference between the highest temperature of the equipment of the computer room air conditioner and the upper limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is less than or equal to the first preset temperature, and if it is determined that the difference between the first difference and the highest temperature of the equipment of the computer room air conditioner is less than the second temperature threshold, then it is determined whether the difference between the first difference and the highest temperature of the equipment of the computer room air conditioner is less than the first preset temperature. For the specific functions and processes of this control unit 104, refer to step S530

[0189] The control unit 104 is further specifically configured such that when the computer room air conditioner operates in the cooling mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is less than or equal to the first preset temperature, it is determined that the difference between the highest temperature of the equipment of the computer room air conditioner and the upper limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is less than or equal to the first preset temperature, and if it is determined that the difference between the first difference and the highest temperature of the equipment of the computer room air conditioner is less than the second temperature threshold, and if it is determined that the difference between the first difference and the highest temperature of the equipment of the computer room air conditioner is less than the first preset temperature, then the set temperature of the computer room air conditioner is decreased by the second preset temperature to be the new set temperature of the computer room air conditioner, and the new set temperature of the computer room air conditioner is recorded. For the specific functions and processes of this control unit 104, refer to step S540

[0190] The control unit 104 is further specifically configured such that when the computer room air conditioner operates in the cooling mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is less than or equal to the first preset temperature, it is determined that the difference between the highest temperature of the equipment of the computer room air conditioner and the upper limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is less than or equal to the first preset temperature, and if it is determined that the difference between the first difference and the highest temperature of the equipment of the computer room air conditioner is less than the second temperature threshold, and if it is determined that the difference between the first difference and the highest temperature of the equipment of the computer room air conditioner is greater than or equal to the first preset temperature, then the set temperature of the computer room air conditioner is maintained, that is, the set temperature of the computer room air conditioner is used as the new set temperature of the computer room air conditioner, and the new set temperature of the computer room air conditioner is recorded.

Wherein, A is a margin constant, and the value range is 0°C to 5°C, preferably 1°C.

[0192] Step 25, if (T 上限 -A)-T max ≥1°C, then set T 制冷设定 = current setting + 1°C.

[0195] In the Figure 13 example shown, when the detected indoor environmental temperature T 内环 -T 制冷设定 ≤0°C, it means that the computer room air conditioner believes that the output has reached balance. At this time, the computer room air conditioner generally maintains the current state unchanged or reduces the output to achieve energy conservation. Further, if (T 上限 -A)-T max ≥1°C, it means that the highest environmental temperature around the equipment in the room is more than 1°C lower than the warning temperature (the margin A has been considered), then the set temperature of the computer room air conditioner can be +1°C on the current basis to save air conditioner energy consumption; if (T 上限 -A)-T max <0, it means that there is no margin left between the highest room temperature and the warning temperature, and it is necessary to lower the set temperature of the computer room air conditioner to lower the room temperature; if 0≤(T 上限 -A)-T max <1°C, it means that there is a certain distance between the highest room temperature and the warning temperature but not too much of a gap, and it is in a state where the combination of energy conservation and reliability is relatively optimal, then maintain the current operating state unchanged.

[0210] The control unit 104 is specifically further configured to, when the computer room air conditioner operates in the heating mode and the compressor is turned on, if it is determined that the difference between the indoor environmental temperature of the computer room air conditioner and the set temperature of the computer room air conditioner is greater than or equal to a first preset temperature, the difference between the minimum equipment temperature of the computer room air conditioner and the lower limit of the preset working environmental temperature range of n devices in the environment where the computer room air conditioner is located is greater than or equal to the first preset temperature, and the difference between the minimum equipment temperature of the computer room air conditioner and the first sum value is less than a first temperature threshold, and if it is determined that the difference between the minimum equipment temperature of the computer room air conditioner and the first sum value is greater than a negative second preset temperature, maintain the set temperature of the computer room air conditioner, that is, use the set temperature of the computer room air conditioner as the new set temperature of the computer room air conditioner, and record the new set temperature of the computer room air conditioner. For the specific functions and processing of this control unit 104, refer to step S750 for details.

[0211] As Figure 14 shown, the control process of the computer room air conditioner in the heating mode further includes:

[0212] Step 34: Determine whether it satisfies T min -(T 下限 +B)>0: If yes, execute step 35; otherwise, execute step 36. Where B is a margin constant, and its value range is 0°C to 5°C, preferably 1°C.

[0213] Step 35: If T min -(T 下限 +B)>0, then set T 制热设定 = current setting - 1°C.

[0214] Step 36: Determine whether it satisfies T min -(T 下限+(T + B) ≤ -1°C: If so, execute step 37; otherwise, maintain the current state unchanged.

[0215] Step 37: If T min -(T 下限 + B) ≤ -1°C, then set T 设定 = current setting + 1°C.

[0216] In Figure 14 the example shown, the heating principle is the same as the cooling principle. When it is detected that there is still a distance between the lowest temperature and the lower limit warning temperature, the heating set temperature is reduced to save energy; when the temperature is too low, the set temperature is increased to raise the room temperature and improve reliability.

[0217] In the solution of the present invention, in combination with the room equipment temperature (such as the temperature T 设备1 of the first temperature probe, the temperature T 设备2 of the second temperature probe, the temperature T 设备3 ) and the air return temperature of the air conditioner (such as the indoor ambient temperature T 内环 ), when the air return temperature of the air conditioner is close to the set temperature, the difference between the equipment ambient temperature and the target value is judged, and the set state of the air conditioner is controlled to achieve the purpose of energy saving. The solution of the present invention mainly detects whether the actual ambient temperature of the equipment is at the energy-saving expected temperature when the room temperature is close to the set temperature of the air conditioner. If it is lower than the expected value, the set temperature of the air conditioner can be increased; and it is independent of the position and distance of the temperature probe, with simple and effective control and strong general applicability.

[0218] In some embodiments, the control device of the computer room air conditioner according to the solution of the present invention further includes: the control unit 104 is further configured to execute the process of dynamically adjusting the set temperature of the computer room air conditioner at intervals, specifically as follows:

[0219] The control unit 104 is further configured to, when the computer room air conditioner is operating in the cooling mode or the heating mode, after adjusting the set temperature of the computer room air conditioner to obtain the new set temperature of the computer room air conditioner, perform timing to obtain a second interval time. For the specific functions and processes of this control unit 104, refer to step S810.

[0220] The control unit 104 is further configured to, after the second interval time reaches a second set time, re-adjust the set temperature of the computer room air conditioner according to the indoor ambient temperature of the computer room air conditioner and the equipment temperature of the computer room air conditioner, and re-obtain the new set temperature of the computer room air conditioner, so as to control the computer room air conditioner to operate according to the newly obtained new set temperature of the computer room air conditioner. Among them, the second set time is such as time t 0 . For the specific functions and processes of this control unit 104, refer to step S820.

[0221] In the solution of the present invention, when the set temperature of the computer room air conditioner changes, it is necessary to wait at least t 0 time (t 0 The value range is 5 min to 30 min, preferably 20 min) to judge and update the set temperature of the computer room air conditioner again. After adjusting the set temperature of the computer room air conditioner, the output of the computer room air conditioner and the change of the room temperature do not respond so quickly. If the adjustment time interval is too short, it is easy to cause over-regulation. Generally speaking, 20 min can make the computer room air conditioner and the room temperature reach a stable state again.
