Description

Technical Field

[0001] This invention relates to the field of air conditioning operation and maintenance management, specifically to an intelligent air conditioning operation management system based on energy conservation and emission reduction. Background Technology

[0002] With the gradual improvement of people's living standards, air conditioning has been widely used in modern buildings. In today's world of increasingly scarce energy, energy efficiency management has become a hot topic of research in all sectors of society. Since the energy consumption of air conditioning systems accounts for a large proportion of that in buildings, the energy efficiency management of air conditioning systems has received even more attention.

[0003] However, because existing air conditioners operate with relatively low noise, users often forget to turn them off when opening windows for ventilation. This results in the air conditioner continuing to run even when windows are open, increasing energy consumption and causing it to operate at high load for extended periods. Furthermore, when the temperature difference between the outside environment and the air conditioner's preset temperature is too large, the air conditioner also experiences high energy consumption and poor cooling / heating performance, which is detrimental to its use and energy conservation efforts.

[0004] Therefore, a solution is needed to address the aforementioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes an intelligent air conditioning operation control system based on energy conservation and emission reduction. When monitoring air conditioning operation, this system simultaneously collects indoor and outdoor temperatures and uses the degree of change in indoor temperature to reflect the air conditioner's ability to alter the indoor temperature during operation. This analysis reveals the air conditioner's capacity to convert energy consumption into temperature, enabling monitoring of its operating efficiency. When efficiency is too low, the system promptly adjusts the air conditioning operation strategy. Through a comprehensive analysis of the air conditioner's operating efficiency, room temperature control capabilities, and heat dissipation capacity by the energy-saving control unit, it provides guidance or forcibly changes the air conditioner's operating temperature based on different situations. This improves energy conservation and emission reduction while ensuring the air conditioner's lifespan. It also solves the problems of forgetting to turn off the air conditioner when windows are open and the difficulties and excessive loads experienced when the air conditioner's operating temperature differs significantly from the outdoor temperature. Therefore, this invention presents an intelligent air conditioning operation control system based on energy conservation and emission reduction.

[0006] The technical solution adopted in this invention is as follows:

[0007] An intelligent air conditioning operation control system based on energy conservation and emission reduction includes a room temperature control unit, an environmental monitoring unit, an operation and maintenance control unit, an energy consumption statistics unit, and an energy conservation control unit. The environmental monitoring unit can acquire outdoor temperature data, process the outdoor temperature data, and send it to the operation and maintenance control unit.

[0008] The room temperature control unit acquires indoor temperature data, calculates the indoor temperature data, obtains the rate of change of indoor temperature, and sends the rate of change of indoor temperature and indoor temperature data to the operation and maintenance management unit.

[0009] The operation and maintenance management unit acquires outdoor temperature data, indoor temperature change rate, and indoor temperature data, and analyzes the outdoor and indoor temperature data to obtain the temperature control resistance value. The operation and maintenance management unit analyzes the indoor temperature change rate, indoor temperature data, and outdoor temperature data to obtain the heat exchange characteristic value, and simultaneously sends the temperature control resistance value and heat exchange characteristic value to the energy consumption statistics unit and the energy saving control unit.

[0010] The energy consumption statistics unit obtains the air conditioner's operating power, temperature control resistance value, and heat exchange characteristic value, analyzes the three to obtain the air conditioner's energy consumption conversion value, performs threshold analysis on the air conditioner's energy consumption conversion value to obtain the air conditioner's energy consumption evaluation, and sends the air conditioner's energy consumption evaluation to the energy-saving control unit.

[0011] The energy-saving control unit acquires the air conditioner energy consumption evaluation, temperature control resistance value, and heat exchange characteristic value, analyzes the air conditioner energy consumption evaluation, temperature control resistance value, and heat exchange characteristic value, generates an energy-saving control signal, and sends the energy-saving control signal to the outside world through the network.

[0012] In a preferred embodiment of the present invention, after the environmental monitoring unit acquires the outdoor temperature data, it arranges the collected outdoor temperature data in order according to the acquisition time, calculates the temperature difference between two adjacent sets of outdoor temperature data in turn, and compares the temperature difference with a threshold. If the temperature difference between two adjacent sets of outdoor temperature data is greater than a preset temperature difference change threshold, the data is marked as invalid and deleted. If the temperature difference between two adjacent sets of outdoor temperature data is less than the preset temperature difference change threshold, no reaction is made.

[0013] In a preferred embodiment of the present invention, the room temperature control unit acquires indoor temperature data, arranges the indoor temperature data in order according to the acquisition time, and calculates the rate of temperature change based on the time difference between two adjacent temperature data.

[0014] In a preferred embodiment of the present invention, the operation and maintenance management unit records the outdoor temperature data as T and the indoor temperature data as t. It calculates the temperature control resistance value F according to the formula F = k|Tt|, where k is a preset coefficient, and the value of k is related to the compression, condensation, and heat dissipation components of the air conditioner. The operation and maintenance management unit records the rate of change of indoor temperature as Δt and calculates the heat exchange characteristic value G according to the formula. Where q is a preset weighting coefficient.

[0015] In a preferred embodiment of the present invention, the energy consumption statistics unit records the air conditioner's operating power as P, and calculates and analyzes the air conditioner's energy consumption conversion value W using a formula. The unit obtains the air conditioner energy consumption conversion threshold W0. The energy consumption statistics unit compares the air conditioner energy consumption conversion value W with the air conditioner energy consumption conversion threshold W0. If the air conditioner energy consumption conversion value W is greater than or equal to the air conditioner energy consumption conversion threshold W0, a normal energy consumption signal is generated. If the air conditioner energy consumption conversion value W is less than the air conditioner energy consumption conversion threshold W0, an abnormal energy consumption signal is generated. The normal energy consumption signal or the abnormal energy consumption signal is used as the air conditioner energy consumption evaluation.

[0016] In a preferred embodiment of the present invention, the energy-saving control unit performs threshold analysis on the temperature control resistance value. If the temperature control resistance value F is less than or equal to a preset temperature control resistance threshold F0, no response is taken. If the temperature control resistance value F is greater than the preset temperature control resistance threshold F0, then according to the formula... The indoor temperature t value that ensures the temperature control resistance value F is less than the preset temperature control resistance threshold F0 is calculated and recorded as the energy-saving temperature value. When the energy-saving control unit receives a normal energy consumption signal, it sends the energy-saving temperature value through the network. When the energy-saving control unit receives an abnormal energy consumption signal, it generates an energy-saving control signal based on the energy-saving temperature value and controls the air conditioner temperature through the temperature adjustment signal.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, when monitoring the operation of an air conditioner, indoor and outdoor temperatures are collected simultaneously, and the degree of change in indoor temperature is also collected. The degree of change in indoor temperature reflects the air conditioner's ability to change the indoor temperature during operation, thereby analyzing the air conditioner's ability to convert energy consumption into temperature, realizing the monitoring of the air conditioner's operating efficiency, and making timely adjustments to the air conditioner's operating strategy when the efficiency is too low.

[0019] 2. In this invention, the energy-saving control unit comprehensively analyzes the air conditioner's operating efficiency, room temperature control capability, and heat dissipation capability. Based on different situations, it provides guidance on temperature or forcibly changes the air conditioner's operating temperature, thereby ensuring the efficiency of the air conditioner's operation. This not only improves the energy-saving and emission-reduction effect but also guarantees the service life of the air conditioner. Attached Figure Description

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0021] Figure 1 This is a system block diagram of the present invention. Detailed Implementation

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides an intelligent control system for air conditioning operation based on energy conservation and emission reduction, such as... Figure 1 As shown, the system includes a room temperature control unit, an environmental monitoring unit, an operation and maintenance management unit, an energy consumption statistics unit, and an energy-saving control unit. The environmental monitoring unit can acquire outdoor temperature data, arrange the collected outdoor temperature data in order of acquisition time, calculate the temperature difference between two adjacent sets of outdoor temperature data, and compare the temperature difference with a threshold. If the temperature difference between two adjacent sets of outdoor temperature data is greater than the preset temperature difference change threshold, it indicates that the change in temperature data exceeds the change in natural temperature and is unreasonable. In this case, the set of data is marked as invalid data and deleted. If the temperature difference between two adjacent sets of outdoor temperature data is less than the preset temperature difference change threshold, no reaction is made. The environmental monitoring unit sends the processed outdoor temperature data to the operation and maintenance management unit.

[0024] The room temperature control unit acquires indoor temperature data, arranges the indoor temperature data in order according to the acquisition time, calculates the rate of temperature change based on the time difference between two adjacent temperature data, obtains the rate of indoor temperature change, and sends the rate of indoor temperature change and indoor temperature data to the operation and maintenance management unit.

[0025] The operation and maintenance management unit acquires outdoor temperature data, the rate of change of indoor temperature, and indoor temperature data. It then analyzes this data to obtain the temperature control resistance value. The analysis process is as follows: The operation and maintenance management unit records the outdoor temperature data as T and the indoor temperature data as t. It calculates the temperature control resistance value F using the formula F = k|Tt|, where k is a preset coefficient. The value of k is related to the air conditioner's compression, condensation, and heat dissipation components. The operation and maintenance management unit analyzes the rate of change of indoor temperature, the indoor temperature data, and the outdoor temperature data to obtain the heat exchange characteristic value. The analysis process is as follows: The operation and maintenance management unit records the rate of change of indoor temperature as Δt and calculates the heat exchange characteristic value G using the formula. Where q is a preset weighting coefficient, and the temperature control resistance value and heat exchange characteristic value are sent to the energy consumption statistics unit and the energy-saving control unit at the same time.

[0026] The energy consumption statistics unit acquires the air conditioner's operating power, temperature control resistance value, and heat exchange characteristic value, and analyzes these three to obtain the air conditioner's energy consumption conversion value. The analysis process is as follows: the energy consumption statistics unit records the air conditioner's operating power as P, and calculates and analyzes it using a formula to obtain the air conditioner's energy consumption conversion value W. The system performs threshold analysis on the air conditioner energy consumption conversion value, obtaining the air conditioner energy consumption conversion threshold W0. The energy consumption statistics unit compares the air conditioner energy consumption conversion value W with the air conditioner energy consumption conversion threshold W0. If the air conditioner energy consumption conversion value W is greater than or equal to the air conditioner energy consumption conversion threshold W0, a normal energy consumption signal is generated. If the air conditioner energy consumption conversion value W is less than the air conditioner energy consumption conversion threshold W0, it indicates that the air conditioner is not effective in changing the indoor temperature. This may be due to excessive heat dissipation efficiency caused by the temperature difference between indoor and outdoor areas, poor cooling and heating effects caused by the aging of the air conditioner itself, or rapid airflow in the room due to open doors and windows, making it difficult for the air conditioner to control the room temperature. In this case, an abnormal energy consumption signal is generated. The normal energy consumption signal or the abnormal energy consumption signal is used as the air conditioner energy consumption evaluation and sent to the energy-saving control unit.

[0027] The energy-saving control unit acquires the air conditioner's energy consumption evaluation, temperature control resistance value, and heat exchange characteristic value. It analyzes these data to generate an energy-saving control signal, which is then sent to the outside via the network. The energy-saving control unit performs threshold analysis on the temperature control resistance value. If the temperature control resistance value F is less than or equal to the preset temperature control resistance threshold F0, it indicates a small indoor-outdoor temperature difference, and no response is taken. If the temperature control resistance value F is greater than the preset temperature control resistance threshold F0, then according to the formula... The system calculates the indoor temperature t value that ensures the temperature control resistance value F is less than the preset temperature control resistance threshold F0, and records this t value as the energy-saving temperature value. When the energy-saving control unit receives a normal energy consumption signal, it sends the energy-saving temperature value through the network, allowing users or managers to promptly understand the energy-saving temperature value and decide whether to change the air conditioner's operating temperature to the energy-saving temperature value according to their own wishes. When the energy-saving control unit receives an abnormal energy consumption signal, it generates an energy-saving control signal based on the energy-saving temperature value and controls the air conditioner temperature through the temperature adjustment signal, forcing the air conditioner's operating temperature to change to the energy-saving temperature value. This prevents excessive differences between the air conditioner's set temperature and the outdoor temperature, which could lead to difficulties in air conditioner operation, compromise the air conditioner's performance, increase energy consumption, and reduce its lifespan.

[0028] In one embodiment, when monitoring the operation of an air conditioner, indoor and outdoor temperatures are collected simultaneously. The degree of change in indoor temperature is used to reflect the air conditioner's ability to change the indoor temperature during operation. This allows for analysis of the air conditioner's ability to convert energy consumption into temperature, enabling monitoring of its operating efficiency. When efficiency is too low, the air conditioner's operating strategy is adjusted in a timely manner. Through the comprehensive analysis of the air conditioner's operating efficiency, room temperature control capability, and heat dissipation capability by the energy-saving control unit, guidance suggestions on temperature or forced changes to the air conditioner's operating temperature are provided according to different situations. This not only improves the effect of energy saving and emission reduction but also ensures the service life of the air conditioner.
