Description

Technical Field

[0001] The present invention belongs to the technical field of temperature control of gas generator sets, and in particular relates to a constant temperature control method and system for a skid-mounted machine room of a gas generator set in a high-cold region. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the promotion and application of gas internal combustion generator sets of various powers, the number of generator sets sold to high-altitude and cold areas or areas with large seasonal temperature differences is gradually increasing.

[0004] Gas generator sets will generate a large amount of heat energy during operation. If this heat is not dissipated in time, it will cause the generator set to overheat, affecting its normal operation and service life.

[0005] In high-altitude and cold regions, the temperature is extremely low. When the cold air enters the machine room, it can take away the heat generated by the unit during operation. However, improper temperature control in the machine room will lead to excessive heat loss in the machine room. The temperature is too low, causing low-temperature damage to various equipment in the machine room, even irreversible damage, which greatly affects the normal operation of the entire set of equipment.

[0006] In the prior art, there are two ways to control the temperature in the machine room. One is natural ventilation. When the unit is running, open the shutters in the machine room; when the unit is stopped, close the shutters at both ends of the machine room. This method has a simple control strategy and is easy to implement. The other is forced ventilation based on the temperature in the machine room. When the temperature in the machine room is high, open the air inlet and outlet shutters, turn on the air inlet fan, and force ventilation; when the temperature is appropriate, turn off the fan.

[0007] The above two control methods have some disadvantages when used in high-cold areas. First, natural ventilation is greatly affected by the ambient temperature and has poor temperature control effect; second, forced ventilation, improper temperature setting will cause frequent fan start and stop, and high failure rate; third, under both methods, the ventilation fan, fire damper, air filter and other components in the machine room that are connected to the outside world will freeze due to the high cold, with a high failure rate and unable to work normally; fourth, it is difficult to continuously control the entire machine room within a suitable temperature range by relying solely on the unit's own heating and forced air intake and exhaust control. Summary of the invention

[0008] In order to solve the above problems, the present invention proposes a constant temperature control method and system for a skid-mounted machine room of a gas generator set in a high-cold area. The present invention can ensure that the skid-mounted machine room can be continuously controlled at a temperature suitable for the operation of the unit under high-cold environmental conditions.

[0009] According to some embodiments, a first solution of the present invention provides a constant temperature control method for a skid-mounted machine room of a gas generator set in a high-cold region, using the following technical solution: A constant temperature control method for a skid-mounted machine room of a gas generator set in a high-cold region, comprising: After the gas generator set in the skid-mounted room is running, the temperature in the skid-mounted room is obtained in real time; Compare the real-time temperature in the skid-mounted machine room with the set temperature values ​​of different levels, select the corresponding air inlet fire damper and exhaust fire damper to open and close based on the comparison results, and adjust the ventilation volume of the fan to achieve temperature control in the skid-mounted machine room; When the temperature in the skid-mounted machine room is greater than the preset temperature upper limit, the angle change amount of the shutters to be adjusted is determined based on the difference between the temperature in the skid-mounted machine room and the preset temperature upper limit, the current opening angle of the shutters, and the target air intake and exhaust volumes to be adjusted, thereby increasing the opening angle of the shutters; After the shutter position has reached the opening limit, the fan speed adjustment control is entered. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change that needs to be changed is determined, and the fan speed is increased; Continuously monitor the changes in air pressure inside the skid-mounted machine room and outside air pressure. When the difference between the inlet air pressure and the exhaust air pressure exceeds the set pressure difference limit, adjust the air pressure inside the skid-mounted machine room by reducing the speed of the inlet fan and send out an alarm signal; The temperature in the skid-mounted machine room is continuously tested, and the shutter angle and fan speed are continuously adjusted according to the real-time temperature in the skid-mounted machine room, the difference between the inlet pressure and the exhaust pressure, the shutter opening angle and the fan speed, so as to achieve precise control of the air intake and exhaust volume of the machine room, thereby maintaining the temperature in the skid-mounted machine room within the set range and keeping the air pressure in the skid-mounted machine room stable. Furthermore, the real-time temperature in the skid-mounted machine room is compared with the set temperature values ​​of different levels, and the corresponding air inlet fire damper and exhaust fire damper are selected for opening and closing based on the comparison result, specifically: When the real-time temperature in the skid-mounted machine room reaches the set temperature value for natural ventilation, the air inlet and exhaust fire dampers are opened to drive the air inlet and outlet shutters to open, thus achieving natural ventilation; When the real-time temperature in the skid-mounted machine room reaches the first, second, third, or fourth level set temperature value, the corresponding level of frequency conversion signal is used to control the inverter, thereby adjusting the speed of the fan to the corresponding level; When the real-time temperature in the skid-mounted room reaches the preset upper temperature limit, the emergency standby air inlet fire damper and air inlet fan are opened, and the inverter is controlled with the maximum Hz frequency conversion signal to achieve the maximum level of ventilation; When the real-time temperature in the skid-mounted machine room drops from the preset temperature upper limit to the temperature of the corresponding level, the frequency conversion signal of the corresponding level is used to control the inverter, thereby adjusting the speed of the fan to the corresponding level; When the real-time temperature in the skid-mounted machine room reaches the preset temperature lower limit, auxiliary heating is turned on to regulate the temperature in the skid-mounted machine room.

[0010] Furthermore, the numerical values ​​of the five levels of set temperature values ​​increase in sequence as the levels increase; The preset temperature lower limit value is less than the first level set temperature value, and the preheating temperature upper limit value is greater than the fifth level temperature value.

[0011] Furthermore, when the temperature in the skid-mounted machine room is greater than the preset temperature upper limit, the angle change amount of the shutter that needs to be adjusted is determined based on the difference between the temperature in the skid-mounted machine room and the preset temperature upper limit, the current opening angle of the shutter, and the air intake and exhaust volume targets that need to be adjusted, specifically: A 需 =T 偏 ×Q 角变 ×K 1 ; Among them: A 需 is the angle change amount that the blinds need to adjust, and the relationship between the angle change amount that the blinds need to adjust and the air intake volume; T 偏 The temperature deviation is the difference between the current temperature in the skid-mounted room and the preset upper temperature limit; Q 角变 K is the change in air volume for each 1° change in angle, indicating the proportional relationship between the change in shutter angle and the change in air volume; 1 is the proportionality factor, which is used to adjust the sensitivity of temperature deviation to the adjustment of the shutter angle; According to the above formula, the change in exhaust volume corresponding to each 1° angle change is selected to determine the relationship between the angle change that needs to be adjusted for the blinds and the exhaust volume.

[0012] Furthermore, after the shutter position has reached the opening limit, the fan speed adjustment control is entered. According to the required adjusted air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change amount to be changed is determined, and then the fan speed is increased, specifically: n 需 =T 偏 ×Q 转变 ×K 2 ; Where: n 需 T is the speed change that the fan needs to adjust; 偏 is the temperature deviation, which is the difference between the current temperature in the skid-mounted room and the preset upper temperature limit; Q 转变 K is the change in air volume corresponding to each change of 1 rpm, which indicates the proportional relationship between the change in fan speed and the change in air volume; 2 is the proportionality factor, which is used to adjust the sensitivity of temperature deviation to fan speed adjustment; According to the above formula, the change in exhaust volume corresponding to each change of 1 rpm can be used to determine the relationship between the speed change that needs to be adjusted for the fan and the exhaust volume.

[0013] Further, when the temperature in the skid-mounted machine room is lower than the preset temperature lower limit, based on the difference between the temperature in the skid-mounted machine room and the preset temperature lower limit, the current opening angle of the shutters, and the air intake and exhaust volume targets that need to be adjusted, the angle change of the shutters that needs to be adjusted is determined, thereby reducing the opening angle of the shutters; After the shutter position is closed, the fan speed adjustment control is entered. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change that needs to be changed is determined, and the fan speed is then reduced.

[0014] According to some embodiments, the second solution of the present invention provides a constant temperature control system for a skid-mounted machine room of a gas generator set in a high-cold region, which adopts the following technical solution: A constant temperature control system for a skid-mounted machine room of a gas generator set in a high-cold region, comprising: The temperature detection module is configured to obtain the temperature in the skid-mounted machine room in real time after the gas generator set in the skid-mounted machine room is running; The temperature control module within the limited level is configured to compare the real-time temperature in the skid-mounted machine room with the set temperature values ​​of different levels, select the corresponding air inlet fire damper and exhaust fire damper to open and close based on the comparison result, and adjust the ventilation volume of the fan to achieve temperature control in the skid-mounted machine room; The shutter opening control module is configured to determine the angle change amount of the shutter that needs to be adjusted based on the difference between the temperature in the skid-mounted machine room and the preset temperature upper limit, the current opening angle of the shutter, and the air intake and exhaust volume targets that need to be adjusted, and then increase the opening angle of the shutter when the temperature in the skid-mounted machine room is greater than the preset temperature upper limit, thereby increasing the opening angle of the shutter; The fan speed control module is configured to enter the fan speed adjustment control after the shutter position has reached the opening limit. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change amount that needs to be changed is determined, and the fan speed is increased; The pressure monitoring and control module in the equipment room is configured to continuously monitor the changes in the air pressure in the skid-mounted equipment room and the outside air pressure. When the difference between the inlet air pressure and the exhaust air pressure exceeds the set pressure difference limit, the air pressure in the skid-mounted equipment room is adjusted by reducing the speed of the inlet fan and an alarm signal is issued; The constant temperature and pressure control module is configured to continuously detect the temperature in the skid-mounted machine room, and continuously adjust the shutter angle and fan speed according to the real-time temperature in the skid-mounted machine room, the difference between the inlet pressure and the exhaust pressure, the shutter opening angle and the fan speed, so as to achieve precise control of the air intake and exhaust volume of the skid-mounted machine room, thereby maintaining the temperature in the skid-mounted machine room within the set range and keeping the air pressure in the skid-mounted machine room stable.

[0015] According to some embodiments, a third aspect of the present invention provides a computer-readable storage medium.

[0016] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the constant temperature control method for a skid-mounted machine room of a gas generator set in a high-cold region as described in the first aspect above.

[0017] According to some embodiments, a fourth aspect of the present invention provides a computer device.

[0018] A computer device comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps in the method for constant temperature control of a skid-mounted machine room of a gas generator set in a high-cold region as described in the first aspect above are implemented.

A processor of a computer device reads the computer instructions from the computer-readable storage medium, and the processor executes the computer instructions, so that the computer device executes the steps in the constant temperature control method for a skid-mounted machine room of a gas generator set in a high-cold region as described in the first aspect above.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts graded temperature control combined with the application of frequency conversion technology to control the speed and air volume of the fan to meet the ventilation needs under different working temperature conditions, and has the effects of high efficiency, energy saving and precise control; according to the real-time monitored temperature, pressure difference, shutter position and fan speed and other information, the shutter angle and fan speed are continuously adjusted to achieve precise control of the air intake and exhaust volume of the machine room, thereby maintaining the temperature in the skid-mounted machine room within the set range and keeping the air pressure in the machine room stable, so that the skid-mounted machine room can be continuously controlled at a temperature suitable for the operation of the unit in a high-cold environment.

[0022] The present invention uses auxiliary heating equipment to provide additional heat when the temperature in the skid-mounted machine room is too low, making the constant temperature control more effective. Adding electric heating ensures that the entire temperature control system will not fail to work normally due to icing problems even in extremely cold conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention.

[0028] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0029] Embodiment 1 like Figure 1As shown, this embodiment provides a constant temperature control method for a skid-mounted machine room of a gas generator set in a high-cold area. This embodiment uses the method applied to a server as an example for illustration. It can be understood that the method can also be applied to a terminal, and can also be applied to a system including a terminal, a server, and a server, and is implemented through the interaction between the terminal and the server. The server can be an independent physical server, or a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network servers, cloud communications, middleware services, domain name services, security services CDN, and big data and artificial intelligence platforms. The terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited to this. The terminal and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in this application. In this embodiment, the method includes the following steps: After the gas generator set in the skid-mounted room is running, the temperature in the skid-mounted room is obtained in real time; Compare the real-time temperature in the skid-mounted machine room with the set temperature values ​​of different levels, select the corresponding air inlet fire damper and exhaust fire damper to open and close based on the comparison results, and adjust the ventilation volume of the fan to achieve temperature control in the skid-mounted machine room; When the temperature in the skid-mounted machine room is greater than the preset temperature upper limit, the angle change amount of the shutters to be adjusted is determined based on the difference between the temperature in the skid-mounted machine room and the preset temperature upper limit, the current opening angle of the shutters, and the target air intake and exhaust volumes to be adjusted, thereby increasing the opening angle of the shutters; After the shutter position has reached the opening limit, the fan speed adjustment control is entered. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change that needs to be changed is determined, and the fan speed is increased; Continuously monitor the changes in air pressure inside the skid-mounted machine room and outside air pressure. When the difference between the inlet air pressure and the exhaust air pressure exceeds the set pressure difference limit, adjust the air pressure inside the skid-mounted machine room by reducing the speed of the inlet fan and send out an alarm signal; The temperature in the skid-mounted machine room is continuously tested, and the shutter angle and fan speed are continuously adjusted according to the real-time temperature in the skid-mounted machine room, the difference between the inlet pressure and the exhaust pressure, the shutter opening angle and the fan speed, so as to achieve precise control of the air intake and exhaust volume of the machine room, thereby maintaining the temperature in the skid-mounted machine room within the set range and keeping the air pressure in the skid-mounted machine room stable.

[0030] like Figure 3 As shown, the method of this embodiment can be implemented mainly including three parts: a core control unit, a main actuator, and an auxiliary heating device, wherein: 1. Core control unit: It consists of three parts: centralized control cabinet, HMI touch screen and temperature sensor. The centralized control cabinet is the core component of the whole set of constant temperature control. It integrates PLC controller, frequency converter, temperature control circuit, operation button and other components and functions; the touch screen HMI centrally displays the operating status of fans, fire dampers and other components in the temperature control system, and the preset temperature control values ​​can be modified on its interface; the sensor collects the temperature in the skid-mounted room in real time. 2. Main actuators: including 1# and 2# air inlet fire dampers, 1# and 2# variable frequency air inlet fans, 1# and 2# shutters, 3# air inlet fire dampers, 3# emergency air inlet fans, 3# shutters, 4# and 5# exhaust fire dampers and 4# and 5# shutters Inlet and exhaust louvers: installed at appropriate locations in the skid-mounted machine room, used for ventilation and to prevent rain, snow or other external impurities from entering the skid-mounted machine room.

[0031] The fire damper is the electric actuator of the shutter. It is installed behind the shutter and operates according to the PLC instructions in the control cabinet to control the opening and closing of the shutter.

[0032] Inlet frequency conversion fan: The fan is controlled by the centralized control cabinet and outputs different speeds according to the different power supply frequencies to adjust the air intake volume.

[0033] Emergency fan: used in emergencies when the temperature in the skid-mounted machine room is too high.

[0034] 3. Auxiliary heating equipment: Heater In the control room and unit room, multiple graphene explosion-proof heaters and centralized control boxes are installed respectively. The heaters, control boxes and temperature sensors in the two spaces form a system. The control box receives the signal from the temperature sensor and automatically adjusts the switch state of the electric heater according to the preset temperature range (preset -15℃, the value can be adjusted). These devices are used to provide additional heat when the temperature in the skid-mounted room is too low, so as to realize automatic auxiliary control of the temperature.

[0035] The heater and control box are used to provide additional heat when the temperature in the skid-mounted machine room is too low, so as to realize automatic auxiliary control of the temperature. They are independent of the skid-mounted machine room ventilator and fire damper control system.

[0036] The skid-mounted machine room is divided into the unit room and the control room according to the functional area. According to the size of the space, the unit room is equipped with 8 sets of explosion-proof heaters and 1 temperature control box, and the control room is equipped with 2 sets of explosion-proof heaters and 1 temperature control box. The explosion-proof heaters in the control room and the unit room can work independently or simultaneously.

[0037] The temperature control box is an integrated control center for equipment such as heaters and temperature sensors. It receives the signal from the temperature sensor and controls the heater on and off according to the preset temperature value through the internal control circuit and algorithm to achieve the purpose of adjusting the temperature.

[0038] Specifically, when the temperature collected by the temperature sensor is lower than the preset temperature (5°C), the control box will send a signal to start the auxiliary heater for heating; when the temperature reaches the preset value (5°C), the control box will send a signal to turn off the auxiliary heater to avoid overheating.

[0039] The constant temperature control system is designed to ensure the stable operation of the generator set in a cold environment. The temperature control system design also takes into account the unit operation mode, gas leakage, and fire alarm conditions for linkage control. The temperature control system is linked with the generator set control system. When the unit is running, the temperature control system automatically starts, and when the unit stops, the temperature control system stops working.

[0040] When the fire protection system in the skid-mounted machine room detects a gas leak, it will transmit the leak signal to the temperature control system. The temperature control system will automatically open all the fire dampers and ventilation fans in the skid-mounted machine room and send out an alarm signal. When the gas leak is eliminated, manual reset is required and the temperature control system can resume automatic operation.

[0041] When the fire protection system detects a fire alarm, it will send a signal to the unit control system to shut down the unit, and transmit the fire signal to the temperature control system, which will automatically close all fire dampers and ventilation fans. The fire alarm level is higher than the gas leak level.

[0042] Electric heating Add electric heating equipment and control to equipment that is connected to the outside world.

[0043] Electric heating of air filter: It is designed to prevent the filter from ice, frost or being affected by low temperature in cold environment which may cause its filtering performance to decrease, and at the same time, it enables the air sucked into the engine to be effectively heated to maintain the normal operation of the engine.

[0044] Electric heating for fire dampers and air inlet fans: In cold environments, provide electric heating for these devices to ensure that they do not fail to work properly due to problems such as icing.

[0045] This embodiment detects the temperature in the skid-mounted machine room through a temperature sensor, and then transmits the signal to the PLC controller in the centralized control cabinet. The PLC will adjust the ventilation mode, the speed and air volume of the air inlet variable frequency fan, and the number of shutters of the air inlet and exhaust fire dampers in real time according to the required temperature range under different operating conditions of the unit to achieve constant temperature control; the constant temperature control system also takes into account the linkage control under gas leakage and fire alarm conditions.

[0046] PLC control methods include automatic control and manual control. In the automatic control mode, the temperature control system can realize automatic control according to the different operating states of the unit and the real-time temperature changes, such as Figure 2 As shown, the automatic control process includes: 1. Unit operation: The constant temperature control system is activated, first natural ventilation, then forced graded variable frequency ventilation. Variable frequency ventilation is considered in two cases: heating or cooling.

[0047] Compare the real-time temperature in the skid-mounted room with the set temperature values ​​of different levels, and select the corresponding air inlet fire damper and exhaust fire damper for opening and closing based on the comparison results, specifically: When the real-time temperature in the skid-mounted machine room reaches the set temperature value for natural ventilation, the air inlet and exhaust fire dampers are opened to drive the air inlet and outlet shutters to open, thus achieving natural ventilation; The unit is running to dissipate heat, and the temperature in the skid-mounted machine room gradually rises. The PLC monitors the temperature in the skid-mounted machine room in real time. When the ambient temperature reaches the natural ventilation set temperature value (20°C), the PLC will control the opening of the No. 1 and No. 2 air inlet fire dampers, as well as the No. 4-1 and No. 4-2 exhaust fire dampers. These fire dampers drive the opening of the inlet and outlet louvers to achieve natural ventilation. Forced graded variable frequency ventilation: Consider the following two situations: heating and cooling in the skid-mounted machine room: When the real-time temperature in the skid-mounted machine room reaches the first, second, third, or fourth level set temperature value, the corresponding level of frequency conversion signal is used to control the inverter, thereby adjusting the speed of the fan to the corresponding level; When the temperature in the skid-mounted machine room reaches the first level set temperature value (25°C), the PLC outputs a first-level frequency conversion signal to the inverter, which controls the 1# and 2# fans to operate at the corresponding speed of 20HZ. By analogy, when the second, third and fourth level set temperature values ​​are 30℃, 35℃ and 40℃, the PLC outputs three levels of frequency conversion signals to the frequency converter, which controls the 1# and 2# fans to operate at the corresponding speeds of 30HZ, 40HZ and 50HZ. The air volume can be adjusted by changing the fan speed. The lower the speed, the smaller the air volume; the higher the speed, the larger the air volume. Adjust the ventilation volume to take away excess heat and adjust the temperature in the skid-mounted machine room.

[0048] When the real-time temperature in the skid-mounted room reaches the preset upper temperature limit, the emergency standby air inlet fire damper and air inlet fan are opened, and the inverter is controlled with the maximum Hz frequency conversion signal to achieve the maximum level of ventilation; When the temperature in the skid-mounted machine room reaches the preset upper temperature limit of 45°C, the emergency standby 3# air inlet fire damper and 3# air inlet fan are opened and run at full speed of 50HZ to achieve maximum ventilation.

[0049] 2. Cooling control: When the real-time temperature in the skid-mounted machine room drops from the preset temperature upper limit to the temperature of the corresponding level, the frequency conversion signal of the corresponding level is used to control the inverter, thereby adjusting the speed of the fan to the corresponding level; When the real-time temperature in the skid-mounted machine room reaches the preset temperature lower limit, auxiliary heating is turned on to regulate the temperature in the skid-mounted machine room.

[0050] Specifically, when the temperature in the skid-mounted machine room drops to 35°C, turn off the 3# air inlet fan and 3# air inlet fire damper; when the temperature drops to 30°C, adjust and control the 1# and 2# fans to operate at 40HZ; when it drops to 25°C, adjust and control the 1# and 2# fans to operate at 30HZ; when it drops to 20°C, adjust and control the 1# and 2# fans to operate at 20HZ; when it drops to the preset temperature lower limit of 15°C, turn off forced ventilation and re-enter natural ventilation. When the temperature in the skid-mounted machine room reaches a high-cold ultra-low temperature, turn on auxiliary heating.

[0051] The numerical values ​​of the five-level setting temperature values ​​increase in sequence as the level increases; The preset temperature lower limit value is less than the first level set temperature value, and the preheating temperature upper limit value is greater than the fifth level temperature value.

[0052] Auxiliary control of air intake volume in skid-mounted machine rooms; 1. Add air volume regulating valve control motors to the air inlet and exhaust windows of the skid-mounted machine room to control the opening angle of the shutters in real time. At the same time, add position sensors for the shutters to accurately adjust the size of the inlet and outlet air volumes according to the control signals given by the PLC; 2. At the same time, add fan speed sensors for air intake and exhaust in the skid-mounted machine room to detect the fan speed in real time and calculate the fan air intake volume. The fan speed can be changed by PLC-controlled inverter to achieve the purpose of controlling the air intake and outlet.

[0053] Auxiliary control of air pressure in skid-mounted machine room: Pressure sensors are installed on the air inlet duct and exhaust duct of the skid-mounted machine room respectively, and an air pressure difference sensor is installed in the skid-mounted machine room. The sensor probes are led to both the inside and outside of the skid-mounted machine room to monitor the pressure difference inside and outside the machine room in real time.

[0054] The signals of the above air pressure difference sensor, position sensor, fan speed sensor and temperature sensor enter the PLC, and the programmable logic controller (PLC) serves as the core control unit and outputs them after processing.

[0055] When the PLC control system detects that the temperature in the skid-mounted machine room is higher than the set upper limit, the control system will calculate the air intake and exhaust volumes that need to be adjusted based on the temperature deviation, the angle of the louver regulating valve, the fan speed, the current air intake volume, and the air intake and exhaust pressures.

[0056] The process is: 1. The PLC reads the temperature value from the temperature sensor in the skid-mounted machine room, compares it with the set temperature value, and calculates the temperature deviation. If it is a positive value, the temperature in the skid-mounted machine room is high.

[0057] Calculation formula: Set the upper limit temperature to T 设 , the current temperature in the skid-mounted machine room is T 当 , then the temperature deviation T 偏 =T 当 -T 设 .

[0058] The ventilation volume is adjusted by adjusting the shutter opening angle. When the shutter opening angle reaches the limit, the fan speed is adjusted. The ventilation pressure difference between the inside and outside of the skid-mounted room is used as the limit signal for system monitoring. The main control logic is as follows: When the temperature in the skid-mounted machine room is greater than the preset temperature upper limit, the angle change amount of the shutter that needs to be adjusted is determined based on the difference between the temperature in the skid-mounted machine room and the preset temperature upper limit, the current opening angle of the shutter, and the air intake and exhaust volume targets that need to be adjusted, specifically: The PLC reads the shutter opening position signal through the position sensor and records the current shutter opening angle. Based on the temperature deviation and the required air intake target, the PLC calculates the required angle change of the shutter. Then, by outputting the control signal, the shutter opening angle is precisely adjusted to change the air intake.

[0059] Calculation formula (according to the air intake volume, the exhaust volume can be calculated in the same way): For the angle adjustment calculation of the blinds, the proportionality factor K is introduced 1 The equivalent is that the shutter angle is linearly related to the air intake volume. The change in air intake volume for each 1° change in angle is Q. 角变 The relationship between the angle change that the blinds need to adjust and the air intake is: A 需 =T 偏 ×Q 角变 ×K 1 ; When the temperature deviation is positive, the calculated required opening angle is also positive, which means that the opening angle needs to be increased.

[0060] in: A需 is the angle change amount that the blinds need to be adjusted, and the relationship between the angle change amount that the blinds need to be adjusted and the air intake volume, that is, the angle size that the blinds should be adjusted to calculated based on the temperature deviation and other relevant factors, in degrees (°); T 偏 The temperature deviation is the difference between the current temperature in the skid-mounted machine room and the preset temperature upper limit, reflecting the degree to which the temperature in the skid-mounted machine room is higher than the set upper limit. The unit is generally Celsius (℃); Q 角变 The change in air volume for each 1° change in angle, indicating the proportional relationship between the change in shutter angle and the change in air volume, in cubic meters per second (m 3 / s); K 1 is the proportionality coefficient, which is used to adjust the sensitivity of temperature deviation to the adjustment of the shutter angle; under different skid-mounted machine room environments and control requirements, K 1 The value of is different. It plays a role in adjusting the influence of temperature deviation on the adjustment of the blinds. It is a parameter used to optimize the control effect and has no specific unit.

[0061] According to the above formula, the change in exhaust volume corresponding to each 1° angle change is selected to determine the relationship between the angle change that needs to be adjusted for the blinds and the exhaust volume.

[0062] 2. After the PLC detects that the position of the shutter has reached the opening limit, it enters the fan speed adjustment control. By reading the signal of the fan speed sensor, the current fan speed is obtained. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the PLC calculates the amount of fan speed change required. By outputting a control signal to the inverter, the fan speed is adjusted, thereby changing the air intake and exhaust volumes.

[0063] After the shutter position has reached the opening limit, the fan speed adjustment control is entered. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change amount to be changed is determined, and the fan speed is increased. Specifically: Calculation formula (calculated based on intake air, exhaust air can be calculated in the same way): For the fan speed adjustment calculation, the proportional coefficient K is introduced 2 The equivalent is that the fan speed is linearly related to the air intake volume. The change in air intake volume corresponding to each change in speed of 1 rpm is Q. 转变 The relationship between the speed change that the fan needs to adjust and the air intake volume is: n 需 =T 偏 ×Q 转变 ×K 2 ; When the temperature deviation is positive, the calculated required speed is also positive, which means that the fan speed needs to be increased.

[0064] in: n 需 The speed change that the fan needs to adjust is the speed that the fan should adjust based on the temperature deviation and other related factors, in revolutions per second (r / s). T 偏 The temperature deviation is the difference between the current temperature in the skid-mounted room and the preset temperature upper limit, reflecting the degree to which the temperature in the skid-mounted room is higher than the set upper limit. The unit is generally Celsius (℃); Q 转变 The change in air volume for each 1 rpm change is expressed in cubic meters per second. 3 / s); K 2 is the proportional coefficient, which is used to adjust the sensitivity of temperature deviation to fan speed adjustment; under different skid-mounted room environments and control requirements, K 2 The value of is different. It plays a role in adjusting the influence of temperature deviation on the fan speed adjustment. It is a parameter used to optimize the control effect and has no specific unit.

[0065] According to the above formula, the change in exhaust volume corresponding to each change of 1 rpm can be used to determine the relationship between the speed change that needs to be adjusted for the fan and the exhaust volume.

[0066] When the temperature in the skid-mounted machine room is lower than the preset temperature lower limit, the angle change amount of the shutters to be adjusted is determined based on the difference between the temperature in the skid-mounted machine room and the preset temperature lower limit, the current opening angle of the shutters, and the air intake and exhaust volume targets to be adjusted, thereby reducing the opening angle of the shutters; After the shutter position is closed, the fan speed adjustment control is entered. According to the required air intake and exhaust volume targets, combined with the current air intake pressure and exhaust pressure conditions, the fan speed change that needs to be changed is determined, and the fan speed is then reduced.

[0067] The PLC continuously monitors the changes in air pressure inside the skid-mounted room and outside through the pressure difference sensor. When the pressure difference exceeds the limit, the system will adjust the air pressure inside the skid-mounted room by appropriately increasing the angle of the shutters and reducing the speed of the air intake fan, and send out an alarm signal to remind the on-site staff to check the system to confirm whether there is any abnormality.

[0068] Finally, by repeating the above process, the PLC control system continuously adjusts the shutter angle and fan speed according to the real-time monitored temperature, pressure difference, shutter position, fan speed and other information to achieve precise control of the air intake and exhaust volume of the skid-mounted machine room, thereby maintaining the temperature in the skid-mounted machine room within the set range and keeping the air pressure in the skid-mounted machine room stable.

[0069] When the PLC control system detects that the temperature in the skid-mounted machine room is lower than the set lower limit, the control system will make opposite adjustments, reducing the air intake and exhaust volumes, and closing the angles of the air intake and exhaust control valves to maintain stable air pressure and temperature.

[0070] When the air inlet pressure is low, the air inlet volume and the air inlet fan speed can be appropriately increased. At the same time, the exhaust air regulating valve and the exhaust air fan speed can be adjusted according to the exhaust air pressure to maintain a suitable air pressure balance, thereby more effectively controlling the temperature in the skid-mounted machine room. (Vice versa when it is higher) When the temperature in the skid-mounted machine room is high in summer, the temperature starts to rise. The control system detects that the inlet pressure is low through the inlet pressure sensor. At this time, the control system will gradually open the air volume regulating valve and increase the fan speed to increase the air volume. At the same time, the exhaust regulating valve and exhaust fan speed are adjusted according to the feedback from the exhaust pressure sensor to keep the air pressure in the skid-mounted machine room stable and effectively reduce the temperature in the skid-mounted machine room.

[0071] In winter or when the load of the skid-mounted machine room is low, the control system will appropriately reduce the air intake and exhaust volume and lower the opening of the control valve according to the temperature drop to maintain the appropriate temperature and pressure in the skid-mounted machine room.

[0072] In manual control mode, the operator can manually open each fire damper and fan based on actual operating conditions.
