Description
Technical Field
[0001] This invention relates to the technical field of air conditioning systems, and more specifically, to a multi-parameter verification and self-repairing early warning alarm method and system for air conditioning rooms. Background Technology
[0002] With technological advancements and increased societal emphasis on energy conservation and low carbon emissions, HVAC systems, which account for over 50% of building energy consumption, have become a key focus in building energy conservation. Furthermore, with the growing demand for energy-efficient and high-quality construction, the construction of air conditioning room systems, which account for 80% of energy consumption within air conditioning systems, has become a priority. This includes the application of high-efficiency equipment and control technologies. Therefore, control based on equipment performance parameters and real-time sensor parameters has become crucial for energy-saving control technologies.
[0003] After a period of operation, some traditional systems experience data distortion due to external interference or vibration of their own sensing components caused by sensors. Although existing control systems generally have functions such as data cleaning and data distortion alarms, technical personnel must repair and verify the data before the system can be put into use. Therefore, this requires a high level of technical expertise from the technicians and is highly dependent on them. If the data cannot be repaired or verified in a short time, the parameters used as the basis for issuing commands by the control system become meaningless, and the automatic operation of the system must be suspended, requiring manual restart by technicians. Furthermore, the skill level of the technicians during the manual repair or verification process can also affect the operation of the system, thereby affecting the safe and stable operation of the air conditioning system.

[0121] The following is a description using specific examples.
[0122] When the system is not operating normally:
[0123] Temperature monitoring, early warning, alarm, and correction:
[0124] Taking the first temperature sensor installed in the cooling water return pipe as an example. When the first temperature acquisition signal T1 sensed by the first flow sensor is inconsistent with the inlet water temperature inside the cooling end of the chiller, such as when the first temperature acquisition signal T1 is higher or lower than the inlet water temperature inside the cooling end of the chiller, the deviation between the first temperature acquisition signal T1 and the inlet water temperature inside the cooling end of the chiller is calculated, and it is determined whether the deviation is less than 5%. If it is less than 5%, the control system determines that the current deviation is acceptable. At this time, the control system outputs a warning signal to remind the operator that the current data distortion of the first temperature sensor is acceptable. This will affect the system; if the deviation is greater than or equal to 5%, the control system determines that the T1 sensed by the first temperature sensor on the cooling water return pipe has a large fluctuation. At this time, the control system will refer to the inlet water temperature inside the cooling unit to repair the first temperature sensor, and adopt the parameters of the cooling unit. After T1 and the inlet water temperature inside the cooling unit stabilize (i.e., the deviation is less than 5%), wait for a preset time period (this preset time period can be adjusted as needed), switch to T1, and output an alarm signal to remind the operator to check and understand the alarm situation and manually cancel the alarm signal. The same method is used to compare and correct the second, third, and fourth temperature sensors in the same way.
[0125] For pressure monitoring, early warning, alarm, and correction:
[0126] Taking the first pressure sensor installed in the cooling water return pipe as an example, when the first pressure sensor fluctuates due to changes in the real-time operating frequency of the cooling water pump, since the pressure in the pipe is related to the square of the pump's operating frequency (P1∝(real-time operating frequency of the cooling water pump / 50)^2*rated head of the cooling water pump), a first reference value is first calculated based on the real-time operating frequency of the cooling water pump. Then, P1 is compared with the first reference value to calculate the deviation between P1 and the first reference value. It is then determined whether the deviation is less than 5%. If it is less than 5%, the control system judges the current pressure deviation to be acceptable. At this time, the control system outputs a warning signal to remind the operator that the first pressure sensor has a deviation, but it does not affect the system operation. If it is greater than or equal to 5%, the control system calculates the frequency change of the cooling water pump based on its real-time operating frequency and, combined with the direct proportionality between frequency and pressure, corrects the pressure of the first pressure sensor and outputs an alarm signal to prompt the operator to check the alarm situation and manually cancel the alarm signal. Similarly, the second, third, and fourth pressure sensors are compared and corrected in the same way.
[0127] Traffic monitoring, early warning, alarms, and correction:
[0128] Taking the first flow sensor installed on the cooling water supply pipeline as an example. When the first flow sensor fluctuates, since the flow rate is related to the first power of the pump's operating frequency (Q1∝(real-time operating frequency of the cooling water pump / 50)*rated flow rate of the cooling water pump), the control system first calculates a third reference value based on the real-time operating frequency of the cooling water pump. Then, it compares Q1 with the third reference value to calculate the deviation between Q1 and the third reference value, and determines whether the deviation is less than 5%. If it is less than 5%, the control system determines that the current flow deviation is acceptable. At this time, the control system outputs a warning signal to remind the operator that the first flow sensor has a deviation, but it does not affect the system operation. If it is greater than or equal to 5%, the control system corrects the flow rate of the first flow sensor according to the relationship between the real-time operating frequency of the cooling water pump and the flow rate, and outputs an alarm signal to prompt the operator to check the alarm situation and manually cancel the alarm signal. Similarly, the second flow sensor is compared and corrected in the same way.
[0129] This invention compares the relevant parameters of temperature, pressure, and flow sensors with those of the equipment in the air conditioning refrigeration room control system, provides warnings and alarms for changes in these parameters, and performs self-repair based on multiple parameters, thereby realizing the impact of key parameter changes on control logic or strategies in unattended operation of the refrigeration room.
