[0002] In extremely cold and frigid areas, the heat dissipation of the equipment in the secondary equipment room of the main and auxiliary control buildings is too large, causing the temperature of the secondary equipment room to be higher than the operating temperature. However, the outdoor temperature is too low at this time, resulting in the inability of the air conditioner to cool in winter and the cabinet over-temperature alarm, making it impossible to ensure the normal operating temperature of the secondary equipment room.

The cooling and heating solutions of air conditioners and electric heaters have high building energy consumption. At the same time, the temperature control effect is poor under extreme temperature conditions. Electrical secondary equipment is a key control device to maintain the stable operation of the power grid. Therefore, it is of great significance to ensure the stable operating temperature of electrical secondary equipment rooms. At present, it is urgent to find a method that can ensure the stable temperature adjustment of the secondary equipment rooms.

[0026] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0027] Figure 1 It is a flow chart of an air conditioning method for an electrical secondary equipment room by introducing a natural cooling source proposed in an embodiment of the present disclosure.

[0028] Among them, it should be noted that the executor of the air conditioning method for electrical secondary equipment room introducing natural cooling source in this embodiment is the air conditioning device for electrical secondary equipment room introducing natural cooling source, which can be implemented by software and / or hardware, and can be configured in a computer device, which can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0029] like Figure 1 As shown, the air conditioning method for electrical secondary equipment room introducing natural cooling source comprises:

[0030] S101: Obtain the outdoor temperature, indoor temperature and indoor dew point temperature of the electrical secondary equipment room.

[0031] Among them, the electrical secondary equipment room refers to a room or area in the power system that is specifically used to install and maintain secondary equipment. Secondary equipment usually includes protection, control, measurement, automation and other equipment. The main function of these equipment is to monitor, protect and control the power system.

[0032] The outdoor temperature refers to the temperature of the air in the external environment of the above-mentioned electrical secondary equipment room.

[0033] The indoor temperature refers to the temperature of the air in the internal environment of the above-mentioned electrical secondary equipment room.

[0034] Among them, the indoor dew point temperature refers to the temperature in the internal environment of the electrical secondary equipment room when the water vapor in the air reaches saturation. When the air cools to this temperature, the water vapor begins to condense into water droplets, forming dew or fog. The dew point temperature is an important indicator for measuring air humidity. The higher the dew point, the more moisture in the air and the greater the humidity.

[0035] It is understandable that personalized scenarios may be encountered during the air conditioning process, and the air conditioning strategies required for different scenarios may be different. Therefore, in the embodiment of the present disclosure, the outdoor temperature, indoor temperature, and indoor humidity between electrical secondary equipment can be obtained, and the indoor dew point temperature can be calculated through software, thereby realizing the perception of environmental parameters and providing reliable data support for subsequent air conditioning.

[0036] S102: Determine a first comparison result between the outdoor temperature and a first preset value, a second comparison result between the outdoor temperature and a second preset value, and a third comparison result between the outdoor temperature and the indoor dew point temperature.

[0037] The first preset value refers to a threshold value configured in advance for the outdoor temperature of the electrical secondary equipment room. The specific value of the first preset value can be flexibly configured according to the scene requirements, and there is no restriction on this. For example, 15°C can be taken.

[0038] The first comparison result may be used to indicate the relationship between the outdoor temperature and the first preset value, or may be used to indicate the difference between the two.

[0039] The second preset value refers to another threshold value configured in advance for the outdoor temperature of the electrical secondary equipment room. The specific value of the second preset value can be flexibly configured according to the scene requirements, and there is no restriction on this. For example, 5°C can be taken.

[0040] The second comparison result may be used to indicate the relationship between the outdoor temperature and the second preset value, or may be used to indicate the difference between the two.

[0041] The third comparison result may be used to indicate the relationship between the outdoor temperature and the second preset value, or may be used to indicate the difference between the two.

[0042] In the disclosed embodiment, when determining the first comparison result between the outdoor temperature and the first preset value, the second comparison result between the outdoor temperature and the second preset value, and the third comparison result between the outdoor temperature and the indoor dew point temperature, a reliable judgment basis can be provided for the subsequent generation of specific control instructions.

[0043] S103: Generate a first control instruction and a second control instruction based on the first comparison result, wherein the first control instruction is used to adjust the speed of the supply fan, and the second control instruction is used to adjust the speed of the exhaust fan, the supply fan is arranged at the air inlet between the electrical secondary equipment, and the exhaust fan is arranged at the exhaust outlet between the electrical secondary equipment.

[0044] The first control instruction may refer to a control instruction for adjusting the speed of the blower generated based on the first comparison result.

[0045] The second control instruction refers to a control instruction for adjusting the speed of the exhaust fan generated based on the second comparison result.

[0046] That is, in the embodiment of the present disclosure, a first control instruction and a second control instruction can be generated based on the first comparison result to adjust the speed of the supply fan and the exhaust fan, thereby achieving air conditioning between electrical secondary equipment.

[0047] S104: Generate a third control instruction according to the second comparison result and the third comparison result, wherein the third control instruction is used to adjust the power of the electric heater arranged on the air inlet side of the blower.

[0048] Among them, the third control instruction refers to a control instruction generated based on the second comparison result and the third comparison result for adjusting the power of the electric heater arranged on the air inlet side of the blower, which can be used to control the temperature of the air delivered by the blower.

[0049] Optionally, in some embodiments, when generating the third control instruction according to the second comparison result and the third comparison result, it is also possible to determine the first difference change information between the outdoor temperature and the sum when the second comparison result indicates that the outdoor temperature is greater than the second preset value, and the third comparison result indicates that the outdoor temperature is less than or equal to the sum of the indoor dew point temperature and the third preset value; determine the first target power value based on the first difference change information; and generate the third control instruction based on the first target power value. Thus, when the second comparison result indicates that the outdoor temperature is greater than the second preset value, and the third comparison result indicates that the outdoor temperature is less than or equal to the sum of the indoor dew point temperature and the third preset value, the first target power value can be determined quickly and accurately based on the first difference change information, and then the third control instruction can be generated.

[0050] Among them, the third preset value refers to a pre-set value for adding the indoor dew point temperature, and its specific value can be flexibly adjusted according to the application scenario, for example, it can be set to 2.

[0051] The first difference change information may be used to indicate how the difference between the outdoor temperature and the sum changes over time, for example, the difference may increase over time, or the difference may decrease over time.

[0052] The first target power value may refer to a new power value of the spot heater determined based on the first difference change information.

[0053] In the embodiment of the present disclosure, when determining the first target power value based on the first difference change information, when the first difference change information indicates that the difference between the outdoor temperature and the sum value decreases over time, a new power value smaller than the current power value is determined as the first target power value according to the degree of difference reduction; conversely, when the first difference change information indicates that the difference between the outdoor temperature and the sum value expands over time, a new power value greater than the current power value is determined as the first target power value according to the degree of difference expansion.

[0054] Optionally, in some embodiments, when generating the third control instruction according to the second comparison result and the third comparison result, when the second comparison result indicates that the outdoor temperature is less than or equal to the second preset value, and the third comparison result indicates that the outdoor temperature is less than or equal to the sum of the indoor dew point temperature and the third preset value, determine the first difference change information between the outdoor temperature and the sum, and the second difference change information between the outdoor temperature and the second preset value; determine the first target power value based on the first difference change information; determine the second target power value based on the second difference change information; determine the maximum power value between the first target power value and the second target power value; and generate the third control instruction based on the maximum power value. In this way, the practicality of the obtained third control instruction can be effectively improved.

[0055] The second difference change information may be used to indicate how the difference between the outdoor temperature and the second preset value changes over time, for example, the difference may increase over time, or the difference may decrease over time.

[0056] The second target power value may refer to a new power value of the spot heater determined based on the second difference change information.

[0057] In the embodiment of the present disclosure, when determining the second target power value based on the second difference change information, when the second difference change information indicates that the difference between the outdoor temperature and the second preset value decreases over time, a new power value smaller than the current power value is determined as the second target power value according to the degree of difference reduction; conversely, when the first difference change information indicates that the difference between the outdoor temperature and the second preset value expands over time, a new power value greater than the current power value is determined as the second target power value according to the degree of difference expansion.

[0058] That is to say, in the embodiment of the present disclosure, when the second comparison result indicates that the outdoor temperature is less than or equal to the second preset value, and the third comparison result indicates that the outdoor temperature is less than or equal to the sum of the indoor dew point temperature and the third preset value, the maximum power value of the first target power value and the second target power value can be determined, and a third control instruction can be generated based on the maximum power value to ensure the practicality of the obtained third control instruction.

[0059] Optionally, in some embodiments, when generating the third control instruction according to the second comparison result and the third comparison result, when the second comparison result indicates that the outdoor temperature is less than or equal to the second preset value, and the third comparison result indicates that the outdoor temperature is greater than the sum of the indoor dew point temperature and the third preset value, the second difference change information between the outdoor temperature and the second preset value is determined; based on the second difference change information, the second target power value is determined; and based on the second target power value, the third control instruction is generated. Thus, when the second comparison result indicates that the outdoor temperature is less than or equal to the second preset value, and the third comparison result indicates that the outdoor temperature is greater than the sum of the indoor dew point temperature and the third preset value, the second target power value can be accurately and quickly determined based on the second difference change information, and then the third control instruction is generated.

[0060] For example, in the embodiment of the present disclosure, when the second difference change information indicates that the difference between the two decreases over time, the second target power value may be less than the current electric heater power; when the second difference change information indicates that the difference between the two increases over time, the second target power value may be greater than the current electric heater power.

[0061] Optionally, in some embodiments, a fan rain and sand venetian blind is provided at the air inlet of the fan, and the fan rain and sand venetian blind is interlocked with the fan start and stop; an exhaust fan rain and sand venetian blind is provided at the air outlet of the exhaust fan, and the exhaust fan rain and sand venetian blind is interlocked with the exhaust fan start and stop. In this way, the stability and safety of the operation of the fan and the exhaust fan can be effectively improved.

[0062] Optionally, in some embodiments, the start-up conditions of the electric heater include: the blower is in the on state; the rain and sand prevention shutters of the blower are enabled with the feedback function; the pressure difference switch is in the closed state, wherein the pressure difference switch is configured on the air duct where the electric heater is located. Thus, the reliability of the operation process of the electric heater can be effectively improved.

[0063] In this embodiment, by obtaining the outdoor temperature, indoor temperature and indoor dew point temperature of the electrical secondary equipment room; determining the first comparison result of the outdoor temperature and the first preset value, the second comparison result of the outdoor temperature and the second preset value, and the third comparison result of the outdoor temperature and the indoor dew point temperature; generating the first control instruction and the second control instruction according to the first comparison result, wherein the first control instruction is used to adjust the speed of the blower, and the second control instruction is used to adjust the speed of the exhaust fan, the blower is arranged at the air inlet of the electrical secondary equipment room, and the exhaust fan is arranged at the exhaust outlet of the electrical secondary equipment room; generating the third control instruction according to the second comparison result and the third comparison result, wherein the third control instruction is used to adjust the power of the electric heater arranged at the air inlet side of the blower. In this way, the air conditioning effect can be improved and energy consumption can be reduced by introducing a natural cold source.

[0064] Figure 2 It is a flow chart of an air conditioning method for an electrical secondary equipment room by introducing a natural cooling source proposed in another embodiment of the present disclosure.

[0065] like Figure 2 As shown, the air conditioning method for electrical secondary equipment room introducing natural cooling source comprises:

[0066] S201: Obtain the outdoor temperature, indoor temperature and indoor dew point temperature of the electrical secondary equipment room.

[0067] S202: Determine a first comparison result between the outdoor temperature and a first preset value, a second comparison result between the outdoor temperature and a second preset value, and a third comparison result between the outdoor temperature and the indoor dew point temperature.

[0068] The description of S201 and S202 can be specifically referred to the above embodiment, which will not be repeated here.

[0069] S203: When the first comparison result indicates that the outdoor temperature is less than or equal to the first preset value, determine a fourth comparison result of the indoor temperature and the indoor set temperature.

[0070] The indoor set temperature refers to the indoor temperature value set for the electrical secondary equipment room, that is, the temperature value that the electrical secondary equipment room needs to reach. The specific value of the indoor set temperature can be flexibly configured according to the application scenario, for example, it can be 18°C.

[0071] The fourth comparison result may be used to indicate the relationship between the indoor temperature and the indoor set temperature.

[0072] That is, in the embodiment of the present disclosure, when the first comparison result indicates that the outdoor temperature is less than or equal to the first preset value, the fourth comparison result of the indoor temperature and the indoor set temperature can be determined, thereby providing a reliable execution basis for the subsequent generation of the first control instruction.

[0073] S204: When the fourth comparison result indicates that the indoor temperature is greater than or equal to the indoor set temperature, generate a first control instruction.

[0074] Optionally, in some embodiments, a first temperature difference between the indoor temperature and the indoor set temperature at a first moment and a second temperature difference at a second moment can be determined, wherein the first moment is adjacent to the second moment and the first moment is earlier than the second moment; when the first temperature difference is greater than the second temperature difference, the speed of the blower is reduced based on the first control instruction; when the first temperature difference is less than the second temperature difference, the speed of the blower is increased based on the first control instruction. In this way, adaptive adjustment of the speed of the blower can be achieved to effectively improve the stability of the indoor temperature of the electrical secondary equipment room.

[0075] The first temperature difference may refer to the difference between the indoor temperature and the indoor set temperature at the first moment, and the second temperature difference may refer to the difference between the indoor temperature and the indoor set temperature at the second moment.

[0076] S205: Determine a first current rotation speed of the air supply fan, and generate a second control instruction according to the first current rotation speed.

[0077] That is, in the embodiment of the present disclosure, the first current speed of the supply fan can be monitored in real time, and then a second control instruction for the exhaust fan can be generated based on the first current speed to ensure the correlation between the exhaust fan control logic and the supply fan control logic.

[0078] Optionally, in some embodiments, when generating the second control instruction according to the first current speed, the second current speed of the exhaust fan may be determined; the target speed may be determined according to the difference between the first current speed and the preset speed; and the second control instruction may be generated according to the difference between the second current speed and the target speed. Thus, the control effect of the obtained second control instruction is effectively improved.

[0079] The preset speed difference refers to the difference between the preset exhaust fan speed and the supply fan speed. In the application scenario, the first current speed may be greater than the target speed, or the first current speed may be less than the target speed, without limitation.

[0080] That is, in the embodiment of the present disclosure, after determining the first comparison result between the outdoor temperature and the first preset value, the second comparison result between the outdoor temperature and the second preset value, and the third comparison result between the outdoor temperature and the indoor dew point temperature, when the first comparison result indicates that the outdoor temperature is less than or equal to the first preset value, the fourth comparison result between the indoor temperature and the indoor set temperature can be determined; when the fourth comparison result indicates that the indoor temperature is greater than or equal to the indoor set temperature, a first control instruction is generated; the first current speed of the air supply fan is determined, and the second control instruction is generated according to the first current speed. In this way, the linkage control effect of the air supply fan and the exhaust fan can be guaranteed based on the second control instruction, and the air pressure stability between the electrical secondary equipment can be guaranteed.

[0081] S206: Generate a third control instruction according to the second comparison result and the third comparison result, wherein the third control instruction is used to adjust the power of the electric heater arranged on the air inlet side of the blower.

[0082] The description of S206 can be specifically referred to the above embodiment, which will not be repeated here.

[0083] In this embodiment, after determining the first comparison result between the outdoor temperature and the first preset value, the second comparison result between the outdoor temperature and the second preset value, and the third comparison result between the outdoor temperature and the indoor dew point temperature, when the first comparison result indicates that the outdoor temperature is less than or equal to the first preset value, the fourth comparison result between the indoor temperature and the indoor set temperature can be determined; when the fourth comparison result indicates that the indoor temperature is greater than or equal to the indoor set temperature, a first control instruction is generated; the first current speed of the air supply fan is determined, and the second control instruction is generated according to the first current speed. In this way, the linkage control effect of the air supply fan and the exhaust fan can be guaranteed based on the second control instruction, and the air pressure stability between the electrical secondary equipment can be guaranteed.

[0084] Based on the above embodiments, the present invention determines to install an air conditioning system for electrical secondary equipment rooms that introduces a natural cooling source in communication rooms, stations, bipolar control and protection equipment rooms, and low-end valve group control and protection equipment rooms with relatively large heat generation according to the heat dissipation of the panel cabinets between the electrical secondary equipment rooms. The system can be composed of three sets of equipment: an air supply box, an exhaust box, and a fan control box.

[0085] The detailed components of each device are as follows:

[0086] 1) Ventilation system overview:

[0087] Equipped with one blower, air volume 9866m 3 / h, power distribution power 2.2kW, frequency conversion control, the blower is equipped with primary and secondary efficiency filters, and there are two differential pressure switches (the differential pressure switches are configured by the electrical team and installed by the electrical construction team);

[0088] The air inlet side of the blower is equipped with an electric duct heater with an electric heating power of 25kW; a pressure differential switch is installed in the duct where the electric duct heater is located (the pressure differential switch is configured by the electrical team and installed by the electrical construction team); an electric rainproof shutter is installed at the air inlet of the blower, powered by 220V and interlocked with the blower.

[0089] One exhaust fan with an exhaust volume of 10739m3 / h, a distribution power of 0.75kW, and frequency conversion control; the exhaust fan outlet is equipped with an electric rainproof shutter, 220V power supply, and interlocking switch with the fan.

[0090] 2) Brief description of power distribution control system:

[0091] A ventilation control box (PLC) is installed at the door of the room. The size of the control box is 800*600 and it is wall-mounted. A button switch is installed at the door outside the room. The ventilation control box has a reserved communication interface and can be connected to the IOT platform for remote monitoring.

[0092] The power distribution control box for the duct electric heater is installed in the suspended ceiling, arranged near the duct electric heater, and the control panel is pulled out to the ventilation control box; the supply fan inverter box and the exhaust fan inverter box are installed in the suspended ceiling, arranged near the corresponding fans, and the inverter operation screen is pulled out to the ventilation control box.

[0093] A temperature sensor is installed outdoors on the air inlet side of the fan, a temperature and humidity sensor is installed on the air outlet side of the fan (behind the air duct electric heater outlet), and one temperature sensor and one temperature and humidity sensor are installed close to the ceiling in the room.

[0094] The ventilation system is used in winter. In principle, when multiple rooms are running online, the duct electric heater should be locked and cannot be turned on to avoid tripping due to overload of the total power load.

[0095] The ventilation system and the multi-split cooling system are two options for cooling, and the cooling mode can be selected or switched manually.

[0096] 3) The fan control box operates according to the recorded temperature of the temperature sensor, where the recorded temperature is as follows:

[0097] Mark the outdoor temperature as T 新馈 , outdoor humidity is H 新馈 , outdoor dew point temperature T 新露 ; Mark the supply air temperature as T 送馈 ; Mark the supply air setting temperature as T 设送 ; Mark the room temperature as T N馈 , the room humidity is H N馈 , room indoor dew point temperature T N露 ; Mark the room's indoor set temperature as T N设 (The supply air dew point temperature is calculated by the supply air temperature and supply air humidity. The supply air dew point temperature is equal to the outdoor dew point temperature. If the outdoor temperature is known, the outdoor humidity and outdoor dew point temperature can be calculated. The indoor dew point temperature is calculated based on the indoor temperature and humidity, and the calculation result is completed by the PLC)

[0098] T N设 =18℃, T 设送 =5℃

[0099] 4) The control logic of the fan control box is as follows:

[0100] Condition 1: T 新馈 ≤15℃,

[0101] Blower frequency conversion: According to T N设 With T N馈 Adjust when T N设 (18℃)≤T N馈(25℃), when the set value is close to the feedback value, the fan speed is reduced, and when the set value and feedback value are enlarged, the fan speed is increased (Note: the air duct pressure difference setting value under the lowest frequency condition should be checked on site for the air supply fan to ensure that the air duct pressure difference can reach the set value when the air supply fan is running at the lowest frequency to avoid affecting the start-up of the air supply duct electric heater);

[0102] Exhaust fan frequency conversion: add or subtract a fixed value based on the frequency of the supply fan (the fixed value is open to be settable). The room needs to maintain a certain negative pressure, so the exhaust fan air volume needs to be slightly larger than the supply fan;

[0103] Rain and sand proof shutters for air blowers: interlocked start and stop with air blowers;

[0104] Exhaust fan rain and sand proof shutters: interlocked start and stop with the exhaust fan.

[0105] Condition 2: T 新馈 ≤T N露 +2℃ or T 新馈 ≤5℃:

[0106] Air supply duct electric heater: According to ①T 新馈 With T N露 +2℃ for adjustment; ②T 新馈 With T 设送 Make adjustments.

[0107] ①When T 新馈 (8℃)≤T N露 +2℃(10+2℃),T 新馈 With T N露 When approaching +2℃, the electric heating power output is reduced, and when expanding, the electric heating power output is increased.

[0108] ②When T 新馈 ≤T 设送 (5℃), T 新馈 With T 设送 The electric heating power output is reduced when approaching, and increased when expanding.

[0109] When conditions ① and ② are met simultaneously, the most unfavorable condition (i.e. the condition with large electric heating output power) shall be used.

[0110] Note: The prerequisite for turning on the electric heater of the air supply duct must meet the following three conditions at the same time: ① The air supply fan is in the on state; ② Feedback of the rain and sand prevention shutters of the air supply fan is in full opening; ③ The pressure difference switch is in the closed state (the pressure difference of the air duct reaches the set value).
